Tile calculator. How many tiles per square meter

Coating from tile was and remains the best choice when it comes to decorating your bathroom. After all, such properties of ceramics as strength, moisture resistance, aesthetics are ideal for the operating conditions of this room. But in view of the not the lowest cost for tiles, there is always an intention to find out how to calculate the tiles for the bathroom. No one needs extra spending on repairs, but there should be enough material exactly so that during the repair process it is not distracted by unnecessary chores.

Room measurements

To calculate the bathroom tiles, you need to take a ruler and measure the room. That is, measure the length of all the edges of the walls. It is easier to measure the area represented by a rectangle or square. In the first situation, two sides are measured, in the other, one.

If there are different curved areas in the room, all parts are measured. The results are recorded and a large-scale plan is drawn up. He will help in drawing up a design project for the renovation. On the plan, you can indicate the location of the installation of plumbing and furnishings.

Basic Calculation Formulas

When calculating tiles for a bathroom, you should take into account the basic formulas for calculating the perimeter of a rectangle and its area.

The area is recognized according to the formula:

and the perimeter is considered as follows:

where the parameters are expressed in letters:

  • S - area, expressed in square meters;
  • P is the perimeter of the room;
  • D is the length of the wall;
  • L - width;
  • H is the height of the wall.

The area of ​​all walls is calculated as the total of the found areas of all walls. Having found this value, the areas of those surfaces that cannot be clad (door and window openings, the space behind the bathroom) are minus from it.

Please note: sometimes, for the sake of economy, they do not plan to tiled with tiles, which will be hidden behind the bathroom. Choosing this finish, the wall area is calculated by measuring the height from the side of the bathroom.

These formulas are the basis for calculating the number of bathroom tiles. In addition, information such as:

  • laying scheme;
  • planned color scheme of finishing;
  • the need to fit the elements according to the pattern;
  • presence / absence of decorative elements (borders, inserts) in addition to the main coating.

Example for calculating volume by area

For clarity on how to calculate the number of tiles in a bathroom, let's look at examples. Presumably, the volume of material must be calculated for a room with the correct rectangular dimensions, in which the following measurements were made and recorded:

  • shortened wall - 2.3 m;
  • long wall - 3.2 m;
  • the height of the walls is 2.5 m.

The calculations will look like this:

With these measurements, the perimeter of the room will be 11 meters = 2.3 * 2 + 3.2 * 2.

The area of ​​the shortened wall is 5.75 m2 = 2.3 * 2.5.

Whereas the long wall will have an area of ​​8 m2 = 3.2 * 2.5.

The total area of ​​the room will be 27.5 m2 = 5.75 * 2 + 8 * 2.

But the cladding area will be smaller. Since the area of ​​the doorway will be removed from it. Which is 1.32 m2 = 0.6 * 2.2, where the width of the opening is 0.6 meters, and its height is 2.2 m.

Then the area that needs to be tiled will be equal to 26.18 m2 = 27.5 - 1.32.

In this case, the floor area for facing will be 7.36 m2.

Examples of calculations for the floor

For example, the choice floor covering fell on elements of a square shape with side lengths of 50 by 50 cm. Therefore, the area of ​​each tile will be equal to 0.25 m2.

To determine how many tiles are needed per bathroom on the floor, the floor area should be divided by the area of ​​one element. If we take the data from the example above, then 7.36 / 0.25 = 30 tiles (round up to a higher number).

Prior to that, it was considered how to calculate the same type of bathroom tiles. However, not many people use the same type of tile. The option of combining elements is often used. In this situation, it is necessary to find out how many tiles would have to be purchased. different types... In this, specialized computer programs can come to the rescue.

Count floor covering possibly in another way. That is, count not according to the floor area, but by the piece. To do this, you also need to know the length with the width at the bathroom. If you use the data from the previous example, the sides of the room will be 230 cm, 320 cm. If the tiles have a side of 50 cm, then 230/50 = 4.6 elements in width will be required (round up to 5 whole pieces). This means that 5 tiles will fit in one row in width. Next, we calculate how many rows will be laid in length 320/50 = 6.4, round up to 7. Then we multiply 5 pieces in one row by 7, we get 35 pieces. Do not forget to add a couple or three pieces in reserve. Therefore, the seller will declare the purchase of 38 pieces.

And now let's compare the results obtained from the example, where the calculations were carried out by floor area and the data, where the quantity was calculated by the piece. The difference is 8 pieces. That is, that would not be enough for the floor cladding and would have to buy them in the future. The second variant of calculations is more accurate and it is more expedient to use a piece-by-piece calculation.

Wall Covering Quantity

To calculate the number of tiles in the bathroom on the walls, it is best to perform the calculations separately for each partition. 250 cm (wall height) must be divided by 33 (tile side in cm) = 7.57 (or exactly 8) pieces - in a row according to the height. 230 cm (wall width) divided by 33 (tile side in cm) = 6.97 (or 7) pieces will fit in a row according to the width. We multiply 8 with 7, we get 56 units with sides of 33 and 33 cm.It is necessary for a smaller wall. By analogy, the number of tile samples required to finish the larger side is calculated. It turns out 80 tiles.

Accounting for door space

For example, the height of the door is 180 cm. Divide it by 33, we get 5.45. We round down, 5 pieces come out in height. The width of the door is 75 cm, we divide it by 33 cm (element side), we get 2.27. Rounding down, we get 2 elements in width. 5 multiplied by 2, we get 10 pieces. If we subtract them, for example, from 80, then we get 70 elements.

Counting the tile on the wall, where part of it is closed by the bathroom, is done in the same way.

Example of calculations with decorative inserts

For calculations, we will consider materials with the following dimensions:

  • rectangular wall elements - dimensions 20 cm x 30;
  • pencils - 1.5 x 20 cm;
  • borders - 10 cm x 20 cm.

We count the total number of borders with pencils. For this we divide the perimeter by the length of each fragment. Remove the width of the doorway from the perimeter value. With our data, it will be like this: (11 - 0.75) / 0.2 = 51.25. Round up to a larger value, we get 52.

Since pencils are placed on each side of the curb tile, its consumption will double, in other words, 104 pieces will be needed. Further, the area that the tile will occupy is considered.

Please note: if a direct layout of elements is selected, then 5% of the material should be added to the estimated number of tiles, and when choosing more complex layout patterns (for example, with a diagonal arrangement of elements), the estimated number of elements is increased by adding 15% of the material.

These examples are enough to carry out the calculations yourself. Knowing them, calculate the required number of tiles, while taking into account doorways and inserts from decorative elements.

The calculator gives our clients an excellent opportunity to calculate the number of tiles required in order to fill the proposed space. In addition, the graphical component of the calculator allows you to combine or fill the space with tiles of the same size and visually reproduce the surface of a wall or floor with a virtual layout before it is carried out on site. To take full advantage of the functional part of the calculator, you need to decide on the tiles that will take part in the calculation, as well as indicate the parameters of the working surface and its characteristics.


1. Let's start by choosing a collection for layout. By clicking on the required type of tile, you are presented with all the options for collections and products that belong to this type. To narrow your search, you can use the site filters.

2. After the required collection or product is found, you need to follow the name link. In this case, the Sketch collection was chosen.


3. Here you need to click on the item "Layout tiles online", where all the elements of the collection on which the choice fell will be presented.


After that, you must follow the instructions given. For correct calculation, you need to indicate the plane on which the layout will be carried out - it can be a wall or a floor. Since in this case the collection is intended only for the floor, the choice of the layout on the wall is not available:


For a more accurate calculation, you need to indicate the characteristic of the seam size, which will also be visualized on the graphic part:

And to choose the direction of laying, it is worth choosing the item of the vertical or horizontal option. In cases where the tile will be different from the square shape, a choice of two options will be available. Since in this case the tile is square, the direction does not play a special role, therefore only one option is available:

In addition, it is possible to specify the size of the surface in the calculator, which will not be taken into account in the calculation. This can be done by clicking on the item "+ Add an area without tiles". The size of the area can be stretched along the edge, or set manually:


After completing the indicated actions at the very bottom, the calculation of all the tiles that took part in the graphic field on the right will be carried out, be it ceramic tiles, porcelain stoneware or various decorative elements of the collection. All counting data will be displayed on the plate. At the bottom of the table, information about the total amount will be displayed, and next to it there will be a button, by clicking which you can quickly add all items to the basket and proceed to checkout. In this case, the instructions for placing an order can be studied starting from point 4.


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 tiles for the bathroom 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 faced 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 different ways:

  • standard;
  • with friezes, borders (wide, narrow or their alternation);
  • 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 installation method, 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.

It 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 in size 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, 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 round = 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 number 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 tile, 177 for light and 31 for frieze.

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 across the width of 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 tile is trimmed 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 already prepared plastered or plasterboard wall with a thickness of 10 mm 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 of 1.5 by 1.7 m, 1.5 x 1.7 x 1.7 = 4.33 kg.

Specialization: Master in Internal and exterior decoration(plaster, putty, tile, drywall, lining, laminate and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all the necessary types of work.

To begin with, you can use a bathroom tile calculator, but I'll warn you right away - this will give you the most inaccurate result. And all the deluge that such programs are not able to take into account the nuances.

However, making such calculations yourself is easy and simple, and they will be the most accurate, up to one unit of tile (although a couple of extra pieces will still be needed in reserve). I suggest that you study a short course of study, or rather, an understanding of the very principle of calculations.

Calculation of tiles for the size of the room

Things to Consider

A room with the same quadrature may require a different amount of material. Therefore, the question of how to calculate the number of tiles in the bathroom also depends on the number and location of plumbing fixtures and pipelines.

There are several nuances that you should pay attention to, since it is most accurate to calculate how many tiles you need in the bathroom, only taking them into account. First of all, in order to understand how to calculate the area of ​​a bathroom for a tile, you need to decide exactly on the installation of plumbing units and the size of the tile itself.

Let's first understand this:

  • the very first thing you need to consider is how the tiles will look in those places that are most visible. As a rule, they are located under the ceiling (top row), as well as above sanitary facilities, for example, above the bathroom;
  • but here the catch is that you can set the height of the same bath arbitrarily, but the height of the ceiling is much more difficult to change. Therefore, the main focus should be on the level of the ceilings;
  • under the ceiling, even if they are suspended, it is desirable to have a whole row, not cut. This means that the calculation of the number of pieces vertically should come from there;

  • therefore, we measure the number of tiles from the stream to the first row (usually, these are 8 pieces of tiles 200 × 300 mm), and leave the bottom row for later;
  • but it also happens when you can fit into an integer number of tiles, then you can also make an uncut row above the bathroom, as shown in the bottom photo;

  • on the walls where the bathroom will be pressed against, the calculation of the tile for the bathroom should not be done - you can leave an empty space there, since no one needs the cladding in an invisible place;
  • The same can be said about the tiles on the floor - tiles are not needed under the bathroom and no instructions require installing them there. The bath fits perfectly on the screed, especially since it is easier to adjust its height this way ;
  • some also save tiles under the curbstones, but I do not advise doing this, it is too "slippery place" - after all, the doors open and you can see everything there;
  • another point in the question of how to calculate the tiles more economically is a shower or a box, although I do not quite understand the meaning of installing a box in a tiled room - this is just absurdity or a thoughtless waste of money;
  • no tiles are needed under the pallet, but it depends on the owner's desire (the area is not large), but why put a box where you still need to put tiles on the walls, since they will be noticeable ?! I repeat once again - this is absurd and there are hardly any arguments to convince me otherwise;

  • one more point, how to calculate the consumption of tiles, is the presence or absence of it on, but there usually the calculation is clean, without any discharges;
  • and finally, these are boxes that can be in any bathroom, although, again, I believe that a large number of them are the negligence of the plumber. They are needed only where a vertical or horizontal pipe cannot be hidden in a strobe.

Calculation examples

As they say in Odessa: "What will I have from this?" In our case, it means how to correctly calculate the tile for a certain layout of plumbing units? Let's start with the total area.

Let's imagine that our area is 3.0 × 2.5m - this, of course, private house but for the example there is no difference. We will take the height of the walls to the rough ceiling 2.6 m, therefore, we will get the whole room 3.0 × 2.5x 2.6 m. Cubature will be of little interest to us, since the tiles should be counted by area.

Again, let's move on to abstract images and, by default, take a tile with a size of 200 × 300 mm, since it is used most often. Spacer crosses will be 3 mm thick (also the most popular).

I will say right away that the thickness of the seam should not be taken into account - this, of course, also refers to the determination of the quantity, but even the most experienced tiler can have force majeure. Any of the tiles may fall and break, or simply burst when cut.

Then one row will require 3000/200 = 15 pieces exactly. But here, for symmetry, you need the width of the seam. This means that between fifteen pieces, there will be 13 seams of 3 mm each, in total, 13 * 3 = 39 mm (we count 40 mm). This means that the extreme tiles will need to be cut 2-3 cm each, leaving 180 mm, although their number will remain the same - 15 pieces.

Then we go to the vertical - everything is calculated in the same way. And if we have a room height of 260 cm (2600 mm), then we need 2600/300 = 8.6 pieces for this. That is, the first row will be slightly more than half. A bit wrong!

The price of the material will decrease if we make the correct calculation:

  1. first, we have seams;
  2. and, secondly, it is not necessary to put the tiles right next to the ceiling, because there will still be floor tiles below.

Therefore, the number of copies can be reduced to 8.5 pieces, then the bottom row will go one after two. This means that below you will need not 15, but only 8 pieces!

Now, let's define areas to skip, especially if it's expensive tiles like 3d. Since it is not needed under the bathroom, then its amount can be calculated from the total square. For example, let's take a bathtub with length / width / height dimensions 1700x700x570 mm (this is an ordinary standard bathroom).

So, if we have 570 mm in height, then the row of tiles above the bathroom will begin (third row 150 + 300 = 450 mm) from 570-450 = 220 mm, that is, practically from a whole row.

We do the same with the end and side in width - we calculate the absence of tiles on this segment. If you want to cover the bathtub with tiles, and not install a plastic screen there, then you should not do such calculations - everything will remain in place.

The calculator itself is a little lower, if you are not interested in the theoretical part, you can. Tiling the bathroom is becoming almost the only acceptable way to tiling the surfaces of sanitary facilities.

In this regard, it is important to know how to calculate the tiles in the bathroom using a calculator specially developed for this purpose by our programmers.

Such a calculation will allow you to purchase materials in the right amount in order to optimize your costs.

Such wall cladding in a room with a bathroom can be laid in a variety of ways, the choice of which depends on many factors, including the design of the material, its size and texture.

Of course, one of the decisive factors is the performer's readiness and professional training.

Calculate bathroom tiles - calculator

How to calculate correctly with an online calculator - preliminary considerations

The program provides for calculating the need for tiles when laying them in a standard way, that is, in rows parallel to the floor, horizontal arrangement of a decorative insert (decorum). Despite the large number of sizes printed on the bathroom diagrams, it should be borne in mind that not all of them are required to be filled in.

For example, if there is only one window in the bathroom, you do not need to fill in the dimensions L3 and L4 or L9 and L10; if there are no windows at all, then the sizes L1 and l2 are not filled either. If the lengths of walls 1 and 3 (diagram1) and, respectively, 2 and 4 (diagram2) are the same, then the size Lb1 is not filled. Under the inequality long walls the size of one of the short sides calculated by the program. Decorative tiles should be installed after a full (uncut) row of the main tile.

"Distance to decor" means the size from the floor to the top edge of the decorative insert, taking into account the number and width of the joints between the tiles. If the decor is missing, all dimensions related to it are not entered! If it is necessary to cover sections of the walls behind the bathroom with tiles, indicate this by clicking on the square button with the corresponding question (under the diagram); a check mark will appear on the button; you can remove it by clicking it again.

THUS, the dimensions Lh, Lb2, Lb3, L5, L6, L8 are obligatory for filling, the dimensions of the bath and the tiles, the width of the joint between the tiles. Size L7 is indicated if the tiles will be run under the door trims. Lb3 can be larger than the length of the bath. The height of the room (Lh) must take into account the skirting board.

The calculation is carried out taking into account that the tiles are laid from bottom to top, from left to right.

Diagonal bathroom cladding method

This method can be used to glue cladding of any size - both square and rectangular. When performing work in this way, the professional training and qualifications of the performer are of great importance.

Diagonal bathroom cladding has several advantages and some disadvantages. TO positive sides include the following:

  1. The rotated position of the plates in relation to each other visually separates the intersecting planes, creating the illusion of a wider space than it really is. This is important when finishing a small room.
  2. The combination of shades, patterns, patterns on the plates makes it possible to create original design premises.
  3. When installed diagonally in the bathroom, the difference in the dimensions of the wall to be finished is partially concealed, which is facilitated by the inclined position of the lines.

At the same time, there are some negative aspects:

  1. Labor intensity and complexity of installation due to a large number cutting operations. Complex markings, cutting and placement of individual parts with a slope require a master of certain experience in performing such work.
  2. When cutting parts diagonally, corners are often chipped, which requires additional refinement of the breaking off with a file.

Preparatory work on surfaces

Before starting work on laying the cladding in a room with a bathtub, it is necessary to assess the condition of the surfaces to be finished:

  1. First of all, the geometric dimensions of the walls are checked. Each surface must be strictly rectangular, if this condition is not met, the walls must be leveled, up to the installation of drywall.


  1. Potholes and irregularities on the surface of the walls also need to be leveled. Irregularities up to three millimeters deep can be leveled tile adhesive in the process of laying it. Deviations from flatness up to seven millimeters deep are best straightened using a putty.
  2. Irregularities with a depth of ten millimeters or more must be removed by wall cladding with waterproof plasterboard.

It should be noted that the alignment of the walls is imperative before using any methods of laying the decoration in the bathroom.

And one more general wish regarding surface preparation. Before starting the cladding, they must be primed with tile adhesive diluted in a ratio of 1: 3. However, this action must be performed in accordance with the instructions - the use of tile glue, for different compositions the requirement may be different.

Diagonal wall trim installation

It is no coincidence that we propose to start with wall decoration. If, during the repair, the floor finish is laid first, the rest of the work will have to be done, moving on the new coating, which can lead to its damage.

The cost of covering the walls with ceramics is not cheap. How to calculate the number of tiles in the bathroom to avoid unnecessary expenses? Diagonal placement assumes its location as a continuous canvas with the smallest fragments cut out.

Therefore, this method, with a high labor intensity, is considered the most economical. Only the parts damaged during cutting go to waste. Therefore, in order to calculate the coverage in a room with a bathroom, it is enough to calculate the total wall area, and, just in case, add about 5% for battle and marriage.

The cladding in the bathroom room should be started from the opposite wall. front door... When laying diagonally, start from the vertical axis. Laying is carried out from the initial part in both directions evenly with the installation of spacer crosses along the seams.

They are inserted between the plates, two pieces per side. The thickness of the foot of the cross is 1.5 mm.

The laying technology is as follows:

  1. A portion of glue is applied to the prepared wall surface, sufficient to install 2-3 plates. The glue is leveled along the wall with a notched trowel, its width should be equal, or better, if it is larger than the format of the part. The lines of the ridges on the adhesive layer must not intersect with each other, as an air bubble can form in this place.

  1. A tile is placed on the glue and pressed tightly against it. The starting plate must be carefully positioned on a plane: it must be installed at the same distance from the wall around the perimeter. The corners of a part installed diagonally should be placed strictly on the axial vertical line marked earlier.
  2. If the plate is skewed, alignment must be done by pressing it. As a last resort, you can besiege it by gently tapping with a sharp rubber mallet.
  3. The next elements are triangular tiles cut in half diagonally. In the gap between the plates, plastic crosses are installed - two pieces per side. The coincidence of the plane of each subsequent part is controlled by a short bubble level, and the overall flatness is controlled by a long construction level.

  1. The upper end of the cladding is formed by completely cut fragments, so it must be finished with cornice elements. You can choose cornices by size and shape in the construction market.
  2. The responsible operation - cutting the plate - is carried out on a special device - a tile cutter. You can, of course, use a glass cutter, but it is much more difficult to get the required cut quality.

The diagonal laying of the coating in the bathroom allows you to get the most decorative compositions.

Laying in a checkerboard pattern

With this method of tile placement, the seams between the individual plates are parallel to the intersections of the walls. This method involves cutting the plates to the size of the remaining gap.

This is not economical, especially if they have an asymmetrical pattern and the leftovers have to be thrown away. Therefore, checkerboarding is used for tiles of small diameter and different colors, which allows you to create original compositions.

But before you take advantage online calculator Ohm, you need to make all measurements of the room and get a clear idea for yourself about the arrangement of your bathroom.

How to use the online tile calculator?

This program is presented in the form of a table, in which for the calculation you need to enter data on your bath:

  1. The geometrical parameters of the room are the length, width of the room and the height of the finishing.
  2. Dimensions of the doorway.
  3. Dimensions of the window opening.
  4. Bath dimensions.
  5. Are the side walls of the bathtub to be tiled? - "Not really".
  6. Selecting the type of layout. There are several options: classic, monochromatic - provides for the use of tiles of the same color, combined - uses several colors.

Data on the parameters of the bathroom, such as the height of the walls, etc. entered in meters.

The dimensions of the openings for the door and window are subtracted from the total area to be finished.

Font dimensions - it is necessary to indicate whether its sides and the floor under the bathtub are to be finished.

Layout options:

  • classic way provides for finishing the room with material of several colors, separated using a border;
  • with a monochromatic finish, the use of decorated inserts is provided;
  • with the combined version, the use of plates of three or more colors is envisaged for finishing.

Thus, the built-in calculator provides a wide range of possibilities for realizing your design ideas.

The size of the plates must be indicated in millimeter units. Decorated plates are counted individually.

To calculate the need for materials for curbs, their location is taken into account along the entire coverage along the generatrix when laying horizontally, as well as along the entire vertical.

It is also necessary to indicate the stock of the main material - usually a value of 5-10% of the total is laid.

We lay with an offset

This method is used quite often, including in combination with those described above. This method does not bring anything fundamentally new to the laying technology.

The calculation of the need for materials remains the same - accordingly, the covered area. This styling method resembles brickwork and is most applicable when working with rectangular plain tiles.


But the method using mosaic inserts gives an undoubted advantage.


The displaced lines effect makes it possible to make styling defects less noticeable.

Final works

Finishing operations do not depend on the laying method. In any case, you will need to seal the seams between the tiles. For this, a special material is produced - grout.

It is usually sold ready-made, packaged in cans. Each manufacturer recommends a certain grade of this material and these tips should be followed.

The grout is applied to the inter-seam space with an elastic rubber trowel. Having typed a little mass on the tip of this tool, you need to rub it into the slot in the transverse direction.

When the gap is evenly filled to the full depth, clean the trowel and use a longitudinal movement to free the tile surface from grout residues. Then you can use a damp sponge and completely clean the surface.



How to account for door and window openings

In the built-in calculators, this calculation operation is included in the program, which will automatically and correctly calculate the number of tiles that would fit in these places.

But if the calculation is done independently, it is enough to take into account the total area of ​​free openings and divide it by the area of ​​one tile. The result obtained in pieces of plates must be subtracted from the amount of materials to cover the total area.

In this case, there is no need to take into account the method of stacking - remember that about 5% of the stock is always included in the calculation. He will serve as a compensating factor for the error in the calculation.

Calculate the need for plastic corners

When working, two crosses are installed on each side of the tile. In this case, each pair works for two tiles. The simplest calculation: divide the number of tiles by two and get the required number of inserts.

We multiply the result by 15-20%, since this little thing tends to get lost in the course of work. The costs for them are so scanty in comparison with the rest that it would not even be worth talking about them.

Calculate your glue and grout needs

The question of the need for grout for tiles in the bathroom can be considered purely theoretically. After all, its number is just as insignificant as crosses-spacers.

The consumption rate of this material is indicated on the packaging, and you can focus on this data when buying.

Tile glue is another matter. It can be sold as a dry mix in sacks and bags, or ready-made in plastic buckets... Naturally, the consumption rate per square meter is available on the package. But this is an average figure.

The actual consumption may turn out to be somewhat different, it depends on the quality of the covered surface. If there are multiple places where the tile has to be leveled due to the thickness of the adhesive layer, the consumption of the binder for its installation will be significantly increased.
