How to count the number of bathroom tiles. How to calculate the required amount of ceramic tiles for the bathroom and toilet

Tile is the most common finishing material that is used for cladding not only internal, but also external surfaces. It tolerates temperature changes, it does not care about high levels of humidity, but most importantly, it is easy to maintain. Choosing this material for an apartment or house, the first thing you think about is the question: how to calculate how many tiles you need in each specific case?

As a rule, most people initially, depending on the cost, purchase an approximate amount necessary material(tiles, wallpaper, etc.). However, approximate calculations lead to unreasonably high costs. The surplus will simply collect dust in some corner, without bringing any benefit. Within the framework of this article, we will try to do without this and carry out a more accurate calculation, based on what exactly the tile will be spent on.

The need for calculation

If you need to make repairs in your apartment or private real estate, you need to calculate everything correctly so that there is no surplus. Some people think that extra material is not a hindrance, but in reality everything is not so simple. During the repair, most people spend a considerable amount of financial resources, and the surplus of tiles leads to unjustified costs. Hardly anyone wants to overpay for floor tiles ?! In addition, its remnants are usually not needed by anyone.

Often, having made an approximate calculation of the amount of material, you can find that it is simply not enough. All that remains is to go to the store and buy the necessary balance. However, everything is not so simple here. The fact is that each batch produced has differences in shades. For this reason, in many stores, samples from the same collection have different prices. As a result of all this, on the floor or walls, you can see areas with different tones, which somewhat spoils the overall impression.

In order to prevent the destruction of harmony in the design of the room, it is better to immediately make the most accurate calculation of the tile as possible. When choosing floor or wall tiles for your room, you should know its pros and cons, so as not to be disappointed later. You may need to give preference to another finishing material, who knows ?!

Tile advantages

The popularity of tiles can hardly be underestimated or overestimated due to the presence of obvious advantages of the material:

• tolerates moisture;
• does not fade in the sun;
• immune to the effects of an aggressive environment;
• easy to clean;
• it can be used in low or high temperature environments;
• relevant for the underfloor heating system in a bathroom or kitchen.

On the market, tiles are supplied in a wide variety of shapes and shades. Thanks to this, the material deservedly enjoys fame among professional designers. It can be used to create original interiors, since the tile itself is already a good decor. In our modern time every year interior decoration of premises is becoming more and more popular. At the same time, not only bathrooms and kitchens are partially finished, as we are used to seeing. Living rooms also look good with elements of such a decor.

Disadvantages of finishing decor

To solve the question of how to calculate how many tiles are needed for different surfaces, you should also know the shortcomings of the material by sight. In comparison with the pluses, there are not so many of them. And one of them is a high degree of rigidity. On the one hand, this is even an advantage, but on the other hand, dishes that have fallen to the tiled floor will inevitably break. Also, due to this quality, serious difficulties arise when cutting tiles. Especially for materials with a glazed surface.

In addition, enamelled and polished tiles are quite slippery. Fortunately for most repair enthusiasts, all these shortcomings are not so serious, so now you can safely proceed to the direct study of calculating the required number of tiles.

Features of the calculation of the facing material

How to calculate the number of tiles? There is no universal option or special formula on this score. Some may immediately argue that it is enough to know the area of ​​the room. In fact, not everything is as simple as it might seem at first glance. It is important to take into account the condition of the floor, what will be the final version, the dimensions of one tile sample. It is also important to consider whether the drawing will be created, the way of laying the tiles and what kind of surface: floor, walls, an apron (usually in the kitchen) or a bathroom (in whole or in part).

Let's try to understand this difficult issue. By calculating using the methods described below, you can determine the net number of tiles. However, in the course of work, it will need to be cut, and therefore another 10-15% should be added to the result obtained. This is the error that is inevitable - the material will break when cutting and the like.

Number of tiles per floor

How to calculate the number of tiles per floor? The dimensions of the room and the tile itself should be taken as a basis. In this case, you can use different ways... For example, let's take the average dimensions of a room, which is typical for most residential buildings: length - 3 meters and width 2 meters. For the calculation, it is better to bring all known ones to one type: length - 300 cm, width - 200 cm, tile dimensions - 20 x 15 cm.

To begin with, you can determine the area of ​​\ u200b \ u200bthe floor in the room and one tile. It's not that difficult - the length is multiplied by the width (the answer is 60,000 cm 2 and 300 cm 2, respectively). Now you need to divide both values ​​among themselves, as a result, you get the amount of material. That is, Q = 60,000 / 300 = 200 (pieces). If the answer is fractional, it must be rounded up, for example, 63.35 = 64.

You can divide the floor length by the same tile parameter (the answer is 15 cm). The same with the width - 200 divided by 15 and we get 13.33. It remains only to multiply the obtained values ​​among themselves and calculate Q = 13.33 * 15 = 199.95, but taking into account rounding - 200 pieces. Taking into account the error - 220-230 pcs., Not less.

Calculation of tiles on the wall

How to calculate wall tiles? Here everything is already a little more complicated. If tiles of the same color will be laid on several walls (or on all 4 as when facing a bathroom), then the calculation can be carried out as with the option for the floor. First, the number of tiles is determined in relation to one wall, and then another, and so on. Finally, the results are summed up, not forgetting to add 10-15%. Only by measuring the walls, it is worth excluding the area of ​​the interior passage, as well as all other places where the tiles will not be.

It's another matter if you need to lay out a kind of pattern or ornament from the tile, as you like. Here it is worthwhile to master a little the specialty of a designer, armed with a pencil and a piece of paper, on which to draw up an approximate drawing, on which the entire drawing and the location of each tile will be clearly visible.

To begin with, it is worthwhile to carry out a standard calculation of a wall tile with a pattern for one of the walls. That is, measure its height and divide by the length of the tile. For example, the height of the room is 250 cm, and the length of the tile is 30 cm. As a result of dividing, we get the answer - 8.3, which we will round up to 9. That is how many horizontal rows there will be.

Next, we take into account the length of the wall (or width), for example, 300 cm (200 cm). Suppose we put square tiles and therefore its other parameter is also 30 cm. Now we calculate the number of vertical rows and as a result of the calculation we have - 10 (20). Now we multiply these two values: 9 * 10 (20) = 90 (180).

Now is the time to turn to our drawing and count how many tiles of a distinctive color. Then this number is subtracted from the total calculated amount.

How many tiles do you need for a bathroom

In fact, determining the number of tiles for a bathroom is practically no different from the examples above. Here you also need to measure the height and length (width) of the walls. Typically, such premises in many residential buildings are made in the correct square or rectangular shape. In this case, if it is a square, it is enough to measure the parameters of one of the walls, and then multiply by 4 during the calculation. Two walls need to be measured in a rectangular room, and again you need to multiply by 2.

Sometimes it is difficult to calculate how many tiles you need for a bathroom. The fact is that the interior of some rooms is complicated by niches and protruding elements. Then you will have to separately measure each surface on which the tile will lie.

The values ​​obtained should be recorded, but for greater convenience it is better to perform the layout of the room. At the same time, indicate the location of plumbing, furniture and other elements. This will allow you to more accurately determine how much material is required and minimize surplus.

Usually, some areas need to be excluded during the calculation. For a bathroom, this is a doorway. There is also no need to lay tiles under the bathroom, as this part of the walls will not be visible. Especially when he puts the screen, which will save a little on material. Therefore, measuring the height of those surfaces to which the bathroom adjoins, it is worth starting from its sides.

Counting tiles on an apron

How to calculate a tile for an apron? Typically, the dimensions of this area, minus the wall cabinets and the allowance for the countertop, is 55-75 cm, which corresponds to the standard. However, in some cases, this work area of ​​the kitchen can be of different dimensions.

To determine how many tiles will go to the apron, it is necessary, first of all, to find out whether it will be made for the entire length of the wall or not.

If the furniture is already present, then you need to measure the necessary parameters:

• the height of the bottom row of cabinets with a table top and legs (if any);
• the height of the top row of cabinets;
• if you have a pencil case, you will need its height.

In addition, you should also take into account the height of the hood, which is usually 72 cm from the countertop and its allowance, which is another 10 cm. It is also necessary to step back from the apron by 3-5 cm in order to hide its edge behind the headset.

If there is no furniture yet (if overhaul or for a number of other reasons), two borders should be marked on the wall below and above. The first is the base cabinet line and the second is the bottom edge of the hanging furniture. You need to draw the lines exactly with the help of a level to the required length. This will allow you to more clearly and accurately resolve the issue of how to calculate how many tiles you need.

In any case, you will get a rectangular section, in which you need to measure the length and height to calculate the area of ​​the apron. If the plot is angular, then calculations are carried out with each of the walls, and after that the two results are summed up. You also need to calculate the area of ​​the tile.

Now it remains to divide the calculated value of the apron by the area of ​​one tile, thus their total number is determined. Only in this case, do not forget about the 10% stock. Fractional numbers are rounded up.

Laying with a diamond

This way of laying tiles on the floor or walls looks more prestigious and harmonious. How to calculate is already known - to determine the area of ​​surfaces (walls, floor) and tiles. Then divide the received data among themselves. For example, the floor area was determined as 7.5 m 2, and the tile - 0.09 m 2. Then the result will be: Q = 7.5 / 0.09 = 83.33, taking into account rounding we get 84 pieces.

The tiles must be laid from the center of the surface to the periphery, the size and shape of the tiles should also be taken into account in this case. In addition, you will need to trim the edges, which increases material consumption. For this reason, the stock will already be 15-20%. That is, in the end we have 97-100 tiles.

Finally

As you can see, calculate required amount facing material is not as difficult as many people think. And to facilitate the whole process or when you are too lazy to carry out all the calculations yourself, there is a convenient opportunity - an online calculator. All you need to do is enter the required data. Therefore, measurements will still have to be carried out.

You can also contact a specialist who will calculate everything on the spot within half an hour. But at the same time, you will have to part with a certain amount of money, as well as listen to the professional opinion that it is better to entrust the installation to specialists. Perhaps even from the company where he works.

But if only an experienced person can really cope with laying tiles, then it is within the power of each of us to decide how to calculate how many tiles are needed. After all, we all went to school, at least for the most part.

A well-thought-out approach to the preparatory period during the renovation will save you the hassle of purchasing building materials and eliminate the formation of an unused, but paid, large balance. And for this it is important to know how to calculate the bathroom tiles correctly.

To calculate the number of bathroom tiles as accurately as possible, you need to measure the room, know and decide on the type of installation.

To begin with, using a tape measure, the required measurements are made. If the bathroom has a square shape, then it is enough to know the dimensions of only one wall, if it is rectangular - two.

Area of ​​a rectangular parallelepiped: S = 2 (A x B + A x C + B x C).

Perimeter: P = 2 (A + B).

Legend:

• S - area, m2;
• P - perimeter, m;
• A is the length of the room;
• B - width;
• С - height.

The existing niches and protrusions must also be fully measured. Then the total working area is the sum of the areas of all surfaces. Then, the area of ​​the doorway and areas that are not planned to be veneered are subtracted from the result.

Wanting to save money, sometimes they don't put the tiles under the bathroom. This space can be closed with a special screen, and the height to the desired level is measured starting from the side of the bath.

Different laying options differ significantly in the required number of tiles. You can lay it in different ways:

• standard;
• with friezes, borders (wide, narrow or alternating);
• diagonal;
• staggered.

With the last two, you will have to trim all the tile parts adjacent to the corners in order to lay them out neatly, which increases the consumption significantly. In addition to the method of installation, it is necessary to decide what color scheme will be applied, whether it will be necessary to fit the pattern, whether only tiles will be used or the design includes any decorative details.

Should be taken into account. It is advisable to start the first rows at some distance from the edge in order to make possible irregularities in the walls less noticeable.

Modern manufacturers produce facing material by itself different shapes and sizes, therefore, having made a choice, you must first measure one plate and calculate its area. Initially, the planned consumption is calculated in square meters, and then specified by the piece.

You cannot make a purchase end-to-end, since it is necessary to provide for a margin for pruning, as well as in case of a battle or marriage, for repairing some area damaged during operation. Based on this, the calculated amount of facing material should be increased by 5% if the selected tile is small or there is a simple pattern. The larger the tile, the more residues when trimming. Or if the drawing is not simple, but a composite of several tiles, you need to add 10%.

Examples of calculations for walls depending on the type of installation

For example, let's take a room with dimensions: A = 1.7 m, B = 1.5 m, C = 2.7 m, doorway 2 mx 0.7 m, tiles 20 x 30.

Plain or standard

The rows are laid out parallel to the floor. The result will be more accurate if you calculate it separately for each wall surface:

• 270 cm (C): 30 cm (tile height) = 9 elements in a row in height;
• 150 cm (H): 20 cm (product width) = 7.5 = 8 pieces (after rounding) in width;
• 9 x 8 = 72 units per wall.

We repeat the steps for the wall, the length of which is 170 cm, the result is - 81. Remove the door size: 200 cm (door opening height): 30 cm = 6.7 = 6 pieces in height (after rounding down):

• 70 cm (door width): 20 cm = 3.5 rounded = 3 pieces in width;
• 6 x 3 = 18 pieces;
• Total: 2 (81 + 72) - 18 + 10% = 316.8 317 pieces are required.

When the walls, near which the bath is installed, will be fully tiled, then the amount of tiles can be easily calculated using the proposed method. If it is planned not to make cladding around it, in this case the calculation is made as for a wall with a door.

We choose wall tiles 30 x 20, borders 10 x 20, border pencils 1.5 x 20.

Let's calculate how many borders and pencils are needed: the perimeter is divided by the length of the element, not forgetting to reduce it to the width of the door. The mathematical calculation looks like this: 2 (1.5 + 1.7) - 0.7 / 0.20 = 28.5 rounded = 29 borders. This is 0.58 m ?.

Usually a pencil is placed on both sides of the curb, which means that it will take twice as much, which means 58 pieces and 0.174 m?.

From the total area of ​​the walls without a door, we subtract the areas of curbs and pencils 15.88 - (0.58 + 0.174) = 15.126 m2. S of one tile: 0.3 m * 0.2 m = 0.06 m ?.

Combined

The bottom is dark tiles, the top is light 20 x 30 and the horizontal frieze is 8 x 20. In this case, we divide three zones: the border is 0.08 m, let the height of the dark “bottom” be 1 m, then the light “top” is 1.62 ...

Laying tiles with decorative borders and crayons

We find the number of dark tiles: the area of ​​the bottom without a door is 2 (1.5 + 1.7) * 1 - 0.7 * 1 = 5.7 m2. The area of ​​one tile: 0.2 * 0.3 = 0.06 m2. Divide the values ​​and add 10%: 5.7: 0.06 * 10% = 104.5, round to 104.

We calculate how many light tiles are needed: the area of ​​the light strip is 2 (1.5 + 1.7) * 1.62 - 0.7 * 1 = 9.668 m2. The area of ​​one tile is already known: 0.06 m2, we divide them: 9.668: 0.06 = 161.13 (pieces) plus 10% = 177.24 or 177 pieces.

How many friezes: 2 (1.5 + 1.7) - 0.7: 0.2 = 28.5 s 10% = 31 pieces.

You will need 104 units of dark tiles, 177 of light tiles and 31 of friezes.

If you plan to place decorative panels or inserts sold by the piece, then the number of the main tiles is correspondingly reduced.

An example of a calculation for a floor depending on the type of installation

The calculations are carried out in the same way as before - the area of ​​the floor and the element is calculated, the amount required to cover the given area is found:

• Floor dimensions - 150 cm x 170 cm;
• Tile - 33x33 cm.

Options for laying tiles on the floor

Parallel, solid color

The calculation for the floor is the same as for the walls with the same installation.

Find the number of tiles in 1 row in width 150: 33 = 4.54, round to the nearest whole - 5 pieces.

How many such rows are in length: 170: 33 cm = 5.15, round up to 6.

5 x 6 = 30 in reserve 2-3 = 33 ceramic tiles.

If the calculation was made only for the floor area: 1.70 mx 1.50 m = 2.55 sq m, divide by S one tile 0.33 mx 0.33 m = 0.11 sq m with 24 tiles rounding, then 9 tiles would not be enough. The first one-by-one method is more correct, it takes into account the inevitable formation of waste when trimming the plates.

This method works well when using monochrome tiles. If a combination of several colors is used, then the amount of each type must be counted separately.

Diagonal or rhombus

The tiles are laid at 45 degrees. Since when laying diagonally, the tiles are cut at the beginning and end of the rows, the percentage of the stock should be made not 10, but 15. The floor area is divided by the area of ​​the tile. In this example, this is 56 pieces, with 15 percent stock (8.4) this would be 64 pieces. Large quantity it is not recommended to purchase, since the cut parts are also used in the work.

How much glue is needed

The cost of glue depends on: the evenness of the wall surface, their condition, the thickness of the adhesive layer. If the surfaces are flawless, then less glue will be needed. In addition, the thickness of the layer itself is of great importance, which directly depends on the height of the spatula teeth, which is selected based on the dimensions of the selected tile: so for a size of 20 x 20, a spatula 6 x 6 mm is needed, 30 x 30 already requires 8 x 8.

Sometimes, for non-professionals it is difficult to choose the right size of the prongs. The angle of inclination of the tool is also taken into account when applying the glue. By making the slope closer to 90 - a thick layer is created, pressing by 45 or less - it decreases. The following table shows the dependence of the thickness of the adhesive layer for all tile sizes on the teeth and the inclination of the trowel. If you need to know for sure, then we offer you more detailed information.

Guided by the instructions for use on the packaging, you can calculate how much glue of the selected brand goes to 1 sq. M.But this information is very approximate. Basically, adhesives for cladding work are divided into three categories: cement-based, dispersion and epoxy. It would not be correct to compare consumption data between them, since they fundamentally differ not only in composition. Tile adhesives are available in the form of powder or liquid, ready-to-use or as a set of components that must be mixed independently. The average volume of any cement-based adhesive mixture per 1 sq. M of an already prepared plastered or plasterboard wall with a thickness of 10 mm adhesive is 17-18 kg. Therefore, with 2 mm of glue (spatula 6 x 6), the consumption is: 2 mm x 17 kg / 10 mm = 1.7 kg per 1 sq.M.For a bathroom floor 1.5 x 1.7 m, 1.5 x 1.7 x 1.7 = 4.33 kg.

When buying materials for repairs, you always want to know their exact amount. On the one hand, this makes it possible not to overpay for unnecessary material, on the other hand, to continue repairs without stopping for additional equipment. not an exception. Accurate calculation of tiles for a bathroom or other premises will make the work easier and avoid additional costs.

The consumption of tiles for laying on floors or walls can depend on many factors. Therefore, before calculating the tiles in the bathroom, it is advisable to properly prepare.

What you need to know in advance

• what configuration will be the material for styling;
• how many colors do you want to use;
• whether decor will be used (borders, drawings that require precise fitting);
• how will the installation be done.

Each of these can significantly affect the number of tiles required for a renovation. For example, laying out diagonally or increasing the consumption - you will have to cut a lot.

And the choice in the catalog of tiles of a single color scheme and direct laying, on the contrary, will be more economical.

After you find the answers to these questions, you can start calculating tiles for a bathroom or any other room.

Counting options

It is enough just to set all the necessary parameters and the system will give you the final amount of material. This option is convenient when using complex patterns and styling methods.

To make tiles by hand, experts offer two options. Let's take a closer look at them.

Area count

If you want to know how many tiles you need in this way, you will have to perform the following measurements:

• measure the area of ​​the base under the tiles;
• measure areas where installation will not be carried out (doors, window openings);
• measure the area of ​​one unit of material.

When all the parameters have been found, it remains to perform simple calculations. Namely, divide the material unit by the area, and, if necessary, round the number up. It is necessary to add 10-15% to the amount of ceramics obtained in order to compensate for the expense for trimming and scrap.

When the calculation is carried out for walls, it will be necessary to first subtract the area of ​​doors and window openings from the total area, if any, and then divide the result by the area of ​​one unit of coverage.

Piecewise calculation

This method assumes a slightly different approach to calculations. And it is easier to explain it with a specific example. Let's say we need to make a calculation for a bathroom with a floor length and width of 3 and 2 m, respectively. The size of the selected ceramics is 30 × 30 cm.

We divide the floor width by the corresponding tile value: 3 / 0.3 = 10. This means that 10 pieces will fit in width. We do the same with the length: 2 / 0.3 = 6.7. Round up to seven. This means that 7 pieces are needed for one row in length. Now we multiply these numbers: 10 * 7 = 70. This is the number of tiles that will need to be used for the floor of this room.

Such a calculation will provide higher accuracy, and is guaranteed to save you from lack of material. But, when using it, it is worth considering one detail. If the required fragment for trimming is no more than 50% of the size of the whole tile, then one piece will make two of them. Accordingly, the total amount will decrease slightly.

In numbers it will look like this:

• we take a floor with dimensions of 2.5 m by 1 m and tiles 30 × 30;
• we count the number of tiles along the length - we get 8 whole and 10 cm for cutting;
• we count in width - 3 whole and 10 cm trim;
• we multiply the integers - 8 * 3 = 24 pcs.;
• count the number of cut fragments:
  • they are 8 in length, 4 in width (3 rows of whole + 1 - of cut ones);
  • we summarize - 8 + 4 = 12 pcs.;

Since the size of one fragment is less than half of one tile, two such pieces can be made from it. And, therefore, the amount of tiles for their manufacture will be 2 times less. That is 12 pcs. divide by 2 and get 6 tiles per undercut. We add them to those that will fit in one piece: 24 + 6 = 30 pcs. And do not forget about 10% to compensate for the marriage.

Those who want to save money and not buy material with interest, such a clarification will come in handy. But it is advisable to do it only with a direct installation option.

In other cases, the probability of error is very high.

The principles for performing the calculation are quite universal and are suitable for any surfaces, rooms, etc. And how to calculate the tile in your case - choose yourself. We hope that our information will help you with this.

In order not to stop work when repairing a bathroom due to a lack of material or not to think about where to put its excess, it is important to correctly calculate the need for a tile. There are several calculation methods, depending on the type of tile laying and differing from each other in accuracy.

With a monotonous bathroom finish, when all surfaces are tiled with the same type of tile laying (straight, diagonal or offset), the need for tiles is calculated in square meters or by the piece.

The amount of ceramics required to complete complex artistic cladding must be calculated separately for each independent fragment of the room's decoration. Let's consider these methods.

Calculation of the consumption of ceramics in square meters

When choosing a monotonous type of tile laying, measurements are made of the dimensions: length, width, height - premises in meters with an accuracy of one hundredth of a fraction (centimeter), rounding up the fractions of a centimeter.

Calculating the consumption of floor finishing

To calculate the squaring of the floor, multiply the metric values ​​of the length and width of the floor, after which the result is rounded to whole units. If laying is carried out in a straight way or "with an offset", add 10% to the amount obtained. If the ceramics are laid diagonally, 15% is added to the floor area.

For example:

The square of the room 4.21 meters long and 2.34 meters wide is:

• 4, 21 x 2, 34 = 9, 8514 sq. Rounded to 10 sq. meters.

Add 10%:

• 10 x 1.1 = 11 sq.

At diagonal way you need to add 15%, it turns out: 10 x 1, 15 = 11, 5 square meters. ≈ 12 sq. M.

Counting material for wall cladding

The squared surface of the bathroom walls is calculated by multiplying the perimeter of the room and its height, the resulting value is also rounded up to whole units:

(4, 21 + 2, 34 + 4, 21 + 2, 34) x 2, 68 = 35, 108 sq. ≈ 36 sq. meters.

Then measure the height and width doorway in meters with an accuracy of a centimeter, rounding down a fraction of a centimeter. Multiplying these values, you get the area of ​​the doorway, rounding it down to tenths of a square meter.

For example:

• the area of ​​the doorway with dimensions of 2, 1 x 0, 8 is 1.68 square meters. ≈ 1.6 sq. M .;
• from the surface area of ​​the walls, subtract the area of ​​the doorway 36-1, 6 m = 34, 4 square meters.

Add 10 or 15% to the result, depending on the type of tile laying and round up to whole values:

• direct or offset method: 34.4 sq. m. x 1, 1 = 37, 84 sq. ≈ 38 sq. M.
• way diagonally: 34, 4 sq. m. x 1, 15 = 39, 56 sq. ≈ 40 sq. M.

If you do not cover the walls behind bathroom, then the area of ​​this hidden surface is also subtracted from the area of ​​the walls, but this savings leads to a weakening of the waterproofing of this area behind the bathroom, which is fraught with damage to the finish in the adjacent room by leaking condensation.

Having calculated how many square meters of tiles are needed for repair, they buy finishing material... The ceramic packaging indicates how many square meters of cladding it contains. To calculate the required number of packs correctly, the need for tiles in square meters must be divided by the quadrature indicated on the package and rounded up to whole values.

Calculating the consumption of tiles by the piece

Individual counting has a smaller error, but this advantage also has a downside - with this method, there is no material left in case of accidental damage to the tile during installation or unforeseen spot repair of the cladding.

With this method, measurements are also made of the dimensions of the room, but in centimeters, rounding off the fractions of a centimeter to whole values ​​upwards. For example, the length of 420.5 cm is rounded up to 421 cm, the width of 233.7 cm - up to 234 cm, and the height of 267.6 cm - up to 268 cm.

Then, a certain tile is looked after in the retail network and the dimensions of one tile are measured. For example, the tile chosen for the walls has a width of 15 cm, a length of 20 cm, and for the floor they chose ceramic 20 x 20 cm.To calculate how many tiles are needed for wall cladding, the consumption must be calculated for each wall separately.

Piecewise calculation of ceramics for walls

In our example, the bathroom has two walls each measuring 421 x 268 cm and 234 x 268 cm.If the tiles are laid vertically, then 268: 20 = 13, 4 pieces will fit from floor to ceiling. With a minimum width of tile joints, this value should be rounded up to 14 items.

In length, 421: 15 = 28, 06 pieces will fit on one wall, on the second - 234: 15 = 15, 6 pieces. Let's round up to 28 and 16 products.

We consider how many pieces are needed for finishing:

• 14 x 28 = 392 pcs.; multiply by two walls, we get 784 products.
• 14 x 16 = 224 pcs.; we also multiply by two walls, we get 448 products.

On vertical surfaces, 1232 pieces will be required, but from this amount you need to subtract the number of tiles, corresponding to the area of ​​the doorway. Suppose the doorway has dimensions of 210 x 80 cm. Its height will fit 210: 20 = 10, 5 pieces. Round down to 10 pieces. The width of the opening will fit 80:15 = 5.33 pcs. Identically round up to 5 items.

Therefore, the area of ​​the doorway corresponds to an area of ​​10x5 = 50 pcs. tiles to be subtracted from the total for the walls: 1232-50 = 1182 pieces.

Piecewise calculation of ceramics on the floor

Let's calculate how many products in the 20x20 cm format will require floor cladding with dimensions of 421x234 cm:

• 421 cm long: 20 cm = 21.05 ≈ 21 pcs.;
• 234 cm wide: 20 cm = 11.7 ≈ 12 pcs.

Multiplying these values ​​gives the number of tiles per floor in pieces:

• 21 x 12 = 252 products.

Calculation of the consumption of ceramics for complex artistic decoration

If it is decided to make the decoration of the bathroom exclusive, the calculation of the ceramics is done in a combined way - by the footage and by the piece. On horizontal and vertical surfaces to be decorated, it is necessary to make markings according to a previously developed sketch map of the cladding. By this time, as a rule, the necessary types of ceramics have already been planned for purchase, and the format of the facing material with which the bathroom will be finished is known.

The markup is carried out with construction chalk, starting from the sections of the main plan, which will be occupied with artistic panels and ornaments, the trimming of which is not allowed for aesthetic reasons. How many tiles are needed for facing such surfaces is easy to calculate by the piece.

Then they calculate the consumption of tiles for the frieze (if available on the sketch map) and cladding under the background for the panel. How much material is needed for laying a frieze can also be calculated by the piece method.

The choice of the method for calculating the amount of ceramics when decorating the main background depends on the cost of the material, since not everyone is planning to buy excess expensive tiles.

Outcomes

The accuracy of calculating the consumption of ceramics when decorating a bathroom depends on the pricing policy. If after the end of the work there is a meter or two of facing material, do not rush to call it a calculation error. This surplus will be indispensable for unforeseen spot repairs of the cladding. It is much worse when there was not enough material, but this type is no longer on sale.

One of the most significant repair issues is the correct calculation of the material, especially when it comes to how to calculate the number of tiles. And if it is easy to buy another finishing material, then in the case of tiles, such an opportunity may not be.

It should be said right away that the correct calculation of tiles is an opportunity to save yourself not only from buying unnecessary material, but also from a more serious problem associated with a lack of tiles. The problem is that modern production tiles are quite complex and, if I may say so, an inconstant process, therefore tiles from the same collection in different batches have significant differences in colors, geometry of the ornament and other technical parameters. You don't need to be an expert to understand how this will affect the design of the entire interior.

It is also worth noting that a lack of experience in taking measurements and calculating the area of ​​a room often leads to incorrect calculations; this issue must be taken no less seriously.

Unfortunately, a single and unchanged calculation formula tile does not exist, since in each individual case everything depends on several factors: the size and features of the layout of the room, the dimensions of the tiles and the layout option. But, in general, the calculation schemes will be similar, and you can understand them at simple example... In this case, the average dimensions of the room and material are taken as a basis. The dimensions of the bathroom are 1.73 × 1.73 m, with a ceiling height of 2.6 m. There are no boxes or niches in the bathroom, and only the doorway is from the openings.

The tiles are laid out vertically in the standard way: dark bottom, border and light top with several decors. The dimensions of the floor tiles are 0.335 × 0.335 m; wall - 0.3 × 0.2 m; frieze dimensions - 0.08 × 0.2 m

There are two ways to calculate floor tiles. Some craftsmen determine the required amount of tiles by area.

Bathroom floor tiles

To do this, you need to know the total square of the room, which is calculated using standard geometric formulas, in this case for a square: 1.73 × 1.73 = 3.46 m2, the number is rounded up and an area of ​​3.5 m2 is obtained. Next, you need to find out the area of ​​one floor tiles: 0.335 × 0.335 = 0.112 m2.

Now they determine how many whole tiles are needed to pave the entire area: 3.5 / 0.112 = 31.2 pieces. The quantity is rounded up to 32 and 10% is added for scrap and trimming, in the case of a diagonal layout - 15%. The total is 35 or 37 tiles, respectively.

The second method is considered more accurate, the tiles are calculated by the piece. Calculate how many tiles fit along one side of the floor (width): 1.73 / 0.335 = 5.2 round up to 6. Now calculate the number of tiles that will fit along the adjacent wall (floor length): 1.73 / 0.335 = 5, 2 are also rounded up to 6, in this case the result is the same. From the calculations, it can be seen that 5 whole tiles and trim will be laid along each of the walls.

Now they will find out how much material is required: 6 × 6 = 36 pieces. Taking into account the fact that when rounding off the number increased by almost one, the correction for battle and marriage is introduced only in the case of a diagonal layout - 5%.

Wall tiles

In order to calculate the required number of tiles for the walls, you need to know the perimeter of the bathroom: (1.73 + 1.73) 2 = 6.92 m, round up to 7 m.Now, knowing the length of one tile, they calculate how many pieces will be laid in one row around the perimeter of the room 7 / 0.2 = 35 pcs.
The layout of the tiles in this case implies a dark bottom, as a rule, it is raised to a height of about 1 m.But since there is no need for trimming here, the height may vary depending on the dimensions of the selected tile: 1 / 0.3 = 33, three rows will be the best option.

Determine the total number of dark tiles in three rows: 35 × 3 = 105, add 3 pieces per battle, for a total of 108 dark tiles.
Dark and light tiles are usually separated by a border. The length of the frieze in this case is similar to the length of the tile - 0.2 m, but it fits only in one row, that is, 35 elements are required to lay out the border around the perimeter.

Now you need to calculate the number of rows of light tiles and their total number. It is known that the height of the room is 2.6 m, the height of the dark layer is 0.9 m, and the border is 00.8 m. It turns out 2.6 - 0.9 - 00.8 = 1.62 m - the height of the light layer. The resulting number is divided by the height of the tile and the number of rows is 1.62 / 0.3 = 5.4, that is, 5 rows of a whole tile and a cut under the ceiling.

Find out the total number of light tiles 35 × 5.4 = 189. In this case, the number need not be rounded to 6, since less than half of one tile is used for trimming in the last row. 4 spare tiles are also added to the total.
The layout of the tile assumes the presence of decors in a bright area, only 3 pieces on three walls and 2 elements on a wall with a doorway. Total: (3 × 3) + 2 = 11 elements. This number must be subtracted from the total number of light tiles 193-11 = 182.

Dark bottom, light top - classic

When calculating wall tiles, do not forget about the presence of a doorway, its height is 2 m, width is 0.7 m. A certain number of tiles can be safely subtracted from the total and save a little.
First, they find out how many whole tiles fit on the height of the opening in one row: 2 / 0.3 = 6.6, here they are rounded down to 6 pieces. Now count the number of tiles per door width: 0.7 / 0.2 = 3.5, also round down to 3 tiles.

It is known that the height of the dark layer is 3 rows, 3 × 3 = 9 dark tiles. The frieze has the same length as the tile, respectively, 3 elements fit the width of the doorway.
Now calculate the number of rows of solid light tiles (2-0.9-0.08) / 0.3 = 3.4, that is, 3 rows of light tiles. Determine the number of light tiles that can be subtracted: 3 × 3 = 9 pcs.
The number of extra tiles for window openings as well as for areas that will not be tiled, for example, behind a bathroom.

The final result

• Floor tiles will be required - 36 pcs.;
• Dark tiles - 94 pieces + 3 spare;
• Light tiles - 169 pieces + 4 pieces. spare;
• Friezes - 32 pieces + 1 piece. in reserve;
• Decors - 11 pcs. + 1 spare.

Advice! Among the more modern and convenient calculation methods, software is now especially popular. Online services enable the user not only to calculate the number of tiles and consumables, but also to create a 3D visualization of the bathtub with a future layout. The only problem is that some manufacturers and collections may not be in the program database.

Programs for calculating tiles in the bathroom

Calculation of consumables

In addition to tiles, you will also need consumables: glue, grout and installation crosses. The latter are sold in packs of 50 pieces, this amount is quite enough. As for glue and grout, it is rarely possible to calculate them perfectly accurately, but it is also easier to buy material in addition than tiles.

Tile adhesive consumption

Average material consumption using the example of Ceresit glue

The consumption of tile adhesive largely depends on the evenness of the walls, which, in practice, usually have to be leveled, and the thickness of the adhesive layer varies greatly. Also, the amount of glue is influenced by the laying technology, brand and composition, manufacturer, masonry technique, tile type and even temperature conditions.
