Calculation of tiles for the bathroom: methods of laying out and determining the amount of consumables. How to correctly calculate tiles for the floor: three reliable ways How to calculate how many tiles you need

It is important to avoid mistakes when tiling a bathroom with expensive imported tiles, as well as additional elements and accessories - cornices, decorative borders, inserts. In this article we will explain how to calculate how many bathroom tiles you need.

In fact, it is not difficult, you just need to take the correct measurements of the room and apply some mathematical calculations. Eat various options, but here we will look at the simplest method using the example of given specific parameters.

Laying different tiles

List of components for the tile collection

To make the calculation, you need to make a list of the collection’s components:

• floor (31x31cm);
• dark wall (25x30cm);
• light wall (25x30cm);
• horizontal border (6x25cm);
• decor (25x30cm);
• pencil (2x25cm).

For example, let's take a bathroom measuring 1.8m x 1.9m and a height of 2.7 meters.

The doorway is 0.7m x 1.95m. We carry out calculations for smooth walls, without taking into account possible niches and protrusions. For clarity and for ease of calculation, it would be useful to draw a plan of the room, marking the dimensions of the walls, doorway, and other planes of interest that need to be calculated.

Calculation of floor tiles

Original version bathroom floor installation

But the calculation by units is considered more accurate. Divide the width of the floor by the size of the tiles:

1.8m: 0.31m = 5.8, round up, to the whole or to the half. We get 6 horizontally.

Divide the length of the bathroom floor by the size of the piece:

1.9m: 0.31m = 6.12. Vertically we have 6.5.

The total quantity for the floor is: 6 x 6.5 pcs = 39 pcs.

As a result, we see that the calculation for tiles differs from the calculation for area. The difference of three units compared to the first calculation is due to the fact that the dimensions of the surface of the floor or walls are not a multiple of the dimensions of the slabs, so they have to be cut. It is also necessary to cut in places of protrusions, niches, pipes, etc. We write down the first result - 39 floor slabs.

Calculation of tiles for walls

All components have the same width - 25 cm. Divide the width of the wall by the width of the slab:

1.8m: 0.25m=7.2 ≈7.5 pcs. ,

and the length of the wall by the width of the tile:

1.9m: 0.25m=7.6≈8 pcs.

In total around the perimeter we get: 7.5 pieces x 2 + 8 pieces x 2 = 31 pieces.

Now you need to subtract the lining for the doorway from the total quantity:

0.7m: 0.25m=2.8≈2.5 (we round down to have a better margin than a deficit.

Subtract from the total: 31 - 2.5 = 28.5.

The row of borders around the entire perimeter is 29 pieces. Since the pencil is placed on both sides of the border (top and bottom), required amount of this element – ​​58.

Laying with decorative borders and pencils

We lay the dark tiles in three rows - the height will be 90 cm. The height of the bathroom is 60 centimeters, there will be 1 dark row above it. Multiply 3 rows by 28.5 (the number of tiles in a row along the perimeter). We get 86 pieces.

The light one will be glued above the border with a pencil and up to the ceiling. From the total height of the room (2.7m), subtract the height of the dark room (90 cm) and the border with a pencil (6cm+2cm+2cm=10cm):

2.7 m - 0.9 m -0.1 m = 1.7 m (height of cladding with light material).

Divide 1.7 m by the height of one:

1.7m: 0.3m= 5.67≈5.5.

In this case, we round down, since when installing a beautiful suspended ceiling you can save some money.

Decors in the bathroom can be glued at your discretion

Now multiply 5.5 in height by 28.5 around the perimeter:

5.5 x 28.5=156.75≈157 pieces.

We return to the area of ​​the wall above the door, which also needs to be lined. Here the number of units in width is:

0.7m: 0.25m=2.8≈3pcs (rounded to the nearest whole number).

The height is 2.7m-1.95m = 0.75m.

0.75m:0.3m= 2.5 pcs.

We multiply 3 in width by 2.5 in height, we get 7.5 (rounded) = 8.

The total number of light ones is: 157 +8 = 165 pieces.

We glue the decors at our discretion and taste: 1 or 2 on each wall, in a checkerboard or other order. Let the tiles that will be replaced with decors (if there are not very many of them, of course) be left in stock just in case (to replace those damaged during use).

Now you have general idea about calculations. If done carefully, they will prevent situations where there may not be enough tiles when laying tiles, and will also save you from unnecessary cash costs.

Typically tiles are sold in square meters. For order floor tiles It’s enough to know the square footage of the room: if your kitchen area is 10 square meters. meters, then you will need to order 10 m of tiles + a reserve for trimming and breaking (usually around 10 percent).

However, sometimes you want to imagine exactly how many tiles will go for each meter. If you just want to imagine this number in order to visualize the picture (how many tiles will go per meter: 4, 10 or 20 tiles), then this is very easy to do. If you need to calculate the exact number of tiles in pieces that you will need to buy in order to lay out a square meter in your room, then this is a little more complicated. (These two values ​​may be slightly different, yes)

Let's start with the easy one: how many tiles per square meter(any meter, completely abstract)

Calculating the area of ​​the tile

First you need to calculate the area of ​​one tile in square meters. For this her length(in meters) needed multiply by width(in meters). It is better to multiply in meters rather than in centimeters, so as not to get confused with the conversion of square centimeters to square meters)

For example, let's take a tile measuring 20x20 cm. Since there are 100 centimeters in one meter, 20 cm is 0.2 meters (20/100 = 0.2). Multiply the length by the width 0.2m x 0.2m=0.04 sq.m. Thus, a 20x20 cm format tile has an area of ​​0.04 sq.m.

If the tile measures 30 cm by 60 cm, the calculation gives 0.3 m x 0.6 m = 0.18 m2. For a tile 12.5 cm x 120 cm, the area will be 0.125 m x 1.2 m = 0.15 m2.

Counting the number of tiles

Knowing the area of ​​one tile, it is enough to divide 1 square meter by this area to get the number of tiles. For a 20x20 cm tile, the calculations will be: 1m2 / 0.04m2 = 25. Thus, there will be exactly 25 20x20 cm tiles per meter.

For a 30x60 cm tile the results will be 1/0.18 = 5.555(5). About five and a half tiles.

It is important to understand that this value is approximate, calculated. In reality, another number of tiles may be needed per meter. Let's see why.

Let's say our room measures one meter by one meter (that is, the same square meter of area), and the tiles measure 30x60 cm. According to preliminary calculations, we needed 5 and a half tiles, right? In reality, we may need 7 tiles

Why is this happening? Because in the calculations the entire area of ​​the material is considered as a whole, as if we had poured it or laid it in tiny pieces. If desired, of course, the scraps from tiles 4, 5 and 6 can be used to cover the area of ​​the seventh tile. This is quite enough, as calculations show. But the length of the remaining pieces is shorter than needed (they are 20 cm each), so it will all look questionable.

Bad news, we'll probably need eight tiles. We want the tile to look beautiful, small pieces are not very aesthetically pleasing, so we’ll align it in the center.

Well, you may decide that the whole problem is that we took a large tile of the wrong size (30x60 cm) for such a small area (1 square meter). Nobody does this, you have to take a small tile. Okay, let's take a 10x10 cm tile. What can happen to it? It would seem like nothing. Exactly 100 pieces of such tiles fit in a square meter (1/0.01=100).

Well, no.

The fact is that a square meter is not necessarily a square room measuring one meter by one meter. It could be narrow corridor measuring 2 meters by 50 cm. What's worse, it could be a passage with the exact dimensions of 57 cm by 1.76 m. Multiple sizes of 10 will instantly give us waste. As a result, the area will require 108 tiles. 18 horizontally, 6 vertically.

Of course, as the footage increases, the percentage of extra tiles usually decreases. In any case, before calculating the number of tiles, decide for yourself for what purposes you need it: just for guidance or for ordering. If you are ordering and you want to count the number of tiles accurate to the piece, you cannot divide the area of ​​the room by the area of ​​the tile. You need to either draw and look, or divide the length of the room by the length of the tiles, the width by the width, and decide how you can combine the remains.

At the very beginning of the renovation, you will inevitably face the problem of calculating the tiles for the floor. Since tile is one of the most popular types facing materials in the bathroom, kitchen and hallway, be sure to familiarize yourself with the rules for carrying out calculations.

When determining the number of tiles, some nuances are taken into account

No matter how much you would like to, it is impossible to estimate by eye how many materials you will need. There are several ways to calculate how many tiles are needed, but they are united by certain characteristics related to the specifics of the work and the properties of the material.

Features of calculations:

• To calculate how many tiles you need, take into account not only the area of ​​the room, but also the size of the tiles.
• Keep in mind that you will have to use whole elements and trim some areas.
• If the floor is not tiled under the bathtub or furniture, subtract the excess amount.
• Layout type plays important role. An offset or diagonal pattern will require more tiles than a straight layout.
• Always add a percentage to the reserve, since during the installation process it becomes necessary to trim some elements, and there is also a risk of defects in the batch, fragments of different colors or damage during work.

Be sure to take into account the presence of trim elements

Please note: when making calculations both straight and diagonally, they take into account how many tiles are needed to cover the ledges and borders.

By room area

There are several ways to calculate the number of floor tiles. The simplest one in the ratio of the areas of one fragment of tile and the room. However, keep in mind that this approach is used when simply laying a seam into a seam.

Calculation method in the first way:

1. Measure the room around the perimeter, each wall.
2. For further calculations, larger values ​​of the width and length of the sides are taken.
3. Multiply both indicators and determine the area of ​​the room.
4. The same calculations are carried out with tiles.
5. Share the results. Please note that the units of measurement must be the same.
6. Add another 10% for reserve. For diagonal laying, add 15%.

The correct calculation of tiles depends on the accuracy of measurements of the working surface area

By number of rows

How else do you calculate how many tiles you need? The best option– use of a method based on determining the number of rows. The number of tiles in each of them must be rounded up, since a fraction means the presence of cut fragments.

1. First, measure the walls of the room.
2. The length of the room is divided into one tile. This gives you the number of rows.
3. Carry out the same actions with the width value. The resulting figure is the number of elements.
4. Round all results up to whole numbers and multiply them together.
5. Add 5-10 percent.

The method is more accurate because it indirectly takes into account the number of threaded elements. The difference in results between the first and second approaches can average about 10-15 tiles, which is actually a significant shortage.

Calculation of tiles by rows

Schematically

Both methods are more suitable for a standard layout scheme, now let’s look at the calculation tiles on the floor when installed diagonally. The problem is solved by developing a circuit flooring. In other words, the number of tiles is counted in the literal sense of the word.

Graph paper is more suitable for the task. Transfer the exact dimensions of the room to scale onto it and mark the boundaries of the area to be covered. Then determine how much one tile occupies in the drawing and draw it according to the diagram (straight, diagonally, staggered) and the direction of laying. Label the whole and cut elements, and then determine the number of tiles.

Computer program

Using the software, you can quickly calculate the amount of facing material

On the Internet there are manuals and online calculators for calculating tiles, however, you should not trust such programs. They do not take into account specific factors of future masonry.

To correctly calculate the consumption of materials, specialized design programs are used. There are trial versions of similar products with limited functions on the Internet. It is not advisable to spend money on purchasing a licensed full version; it is better to seek help from a designer or a consultant at a hardware store. Elite salons will definitely provide a counting service. At the same time, determine the number of whole and cut fragments at optimal scheme laying both straight and diagonal.

The fate of your repair depends on the correct determination of the number of tiles. If you make a mistake and buy more, it’s no problem, because the leftovers will come in handy in the future. And if there is a shortage, you risk facing a situation where there is no suitable tile to buy the missing quantity.

Depending on the specific type, the cost of ceramic tiles can reach large values. Its rational use is one of the options for reducing costs finishing works. Correct calculations needs -effective method savings Money. How to accurately calculate bathroom tiles and reduce waste? The work should be done in several stages.

First, let's look at the simplest option for finishing bathroom walls - ordinary plain tiles are used for the work.

We will not touch on the decorative side of the matter; we will talk about its characteristics from the point of view of tilers. They love this material very much for several reasons:

• During installation there is no need to monitor the placement of individual tiles taking into account the pattern. This not only greatly speeds up the installation process itself, but also simplifies marking. You can start laying tiles from any corner and place; there is no need to select its position to obtain a symmetrical pattern;

  Such mistakes cannot be made when working with plain tiles.

• tiles can be cut from any side, the segments are used without reference to the location of the pattern;
• It is possible to use pieces of tile from one corner wall to another without preliminary adjustment. Less work and less waste.

Calculation technology more complex options We will describe the tiles below, but now we will consider a simple option.

Important. The tiles are sold in packages, in a pack of 0.5 m2, 1 m2 or another quantity (check the number on the package). It is unlikely that any of the sellers will agree to sell tiles individually, in this regard, you should not count the number of pieces, operate square meters. By the way, these calculations are universal and are suitable for determining ceramic tiles various sizes, and they can fluctuate within wide limits.

Step 1. Measure the length of all walls of the room. Use an ordinary tape measure, write down the data in a notepad or on a piece of paper. Add up the total length of the perimeter.

Step 2. Measure the height of the room and round off the resulting values ​​to the nearest centimeter.

Let's look at an example. How to calculate tiles for bathroom walls? First, determine the length of the perimeter. Calculation: 1.5 m+3.0 m+1.5 m+3.0 m = 9.0 m. For example, our ceiling is 2.7 m from the floor. Total surface area 9.0 m x 2.7 m = 24.3 m 2 .

Step 3. From this value, subtract the area of ​​the door and window opening.

The dimensions of the doorway are 2.0 m (height) × 0.9 m (width) = 1.8 m 2. If you wish, then add the area of ​​the platbands to the area of ​​the opening. Their width can vary from five to ten centimeters. But we do not recommend doing this for several reasons.

1. The savings are not so great as to be worth paying attention to. And any calculations may be incorrect, so there is no need to take unnecessary risks.
2. Some types of platbands are fixed to surfaces liquid nails. It's fast and beautiful, no nails or screws are visible. Liquid glue holds well on smooth surfaces; using it on ceramic tiles is the optimal technology.
3. Not all the walls in the bathroom are smooth; some have to be corrected under the trim. Why do the same work twice - lay it around the perimeter of the opening ceramic tiles, don't waste your time.

The same applies to the window opening, if there is one in the room, of course. In our example, there is no window, which means the wall area is 24.3 m2 - 1.8 m2 = 22.5 m2. But this is not the final figure yet.

Step 4. Take the dimensions of the bathtub.

If it is installed against a wall, then there is no need to tile invisible surfaces. For example, the width of the bathtub is 0.7 m, length 1.7 m, height 0.6 m. The bathtub will be adjacent to two walls, one at the end, and the second at the side. It is necessary to calculate the abutment area. From the end it is equal to 0.6 m (height) × 0.7 m (width) = 0.42 m 2. From the side it is equal to 0.6 m (height) × 1.7 m (length) = 1.02 m 2. We add these values ​​0.42 m2 + 1.02 m2 = 1.44 m2.

Step 5. We calculate the exact surface area of ​​the bathtub walls for the tiles: 22.5 m2 (without doorway) – 1.44 m2 (junction area) = 21.06 m2, after rounding we get 21 m2.

Important. If the decorative screen is finished with the same tiles, then its dimensions will not be subtracted.

As during any construction work, you can’t do without unproductive tile waste. How much stock should I leave? There are several factors to take into account:

• qualified tiler. If a professional works, then 5% is enough. For a beginner total tiles need to be increased by 10%;
• decorative characteristics of tiles. If the tiles have asymmetrical patterns, then the segments cannot be used. The margin must be increased to 10%, regardless of the skill of the performer;
• availability and location of water supply and sewer pipes. When finishing these obstacles, tile consumption may increase.

Tiles can be laid in a standard way(rows parallel to the floor), in checkerboard, ordinary diagonal and checkerboard diagonal order. Keep in mind that during the checkerboard-diagonal method the amount of waste may increase slightly, but a 10% reserve will be sufficient in any case. At this point the calculation is completed, you can go to the store to buy the material.

wall tiles for bathroom

What to do if there is a border in the bathroom

Step 1. Measure the height of the border and the number of rows of tiles. The height should correspond to the size of the tile.

Step 2. Measure the length of the walls along which the border will be laid, multiply the value by the height. This will give you the total area of ​​the curbs.

Step 3. Calculate the area of ​​one tile, divide the area of ​​the borders by the area of ​​the tile. This quantity need to increase by 3–4 pcs. depending on the number of turns.

Calculation example:

• the length of the walls minus the doorway is 9 m (perimeter of the bathroom) - 0.9 m (width of the doorway) = 8.1 m;
• border area for tiles 15 cm high: 8.1 m × 0.15 m = 1.215 m 2;
• the border has a height of one tile of 15 cm. The area of ​​the tile is 0.15 m × 0.15 m = 0.0225 m 2;
• number of tiles. 1.215 m2: 0.0225 m2 = 54 pcs. 2 pcs are enough for stock, buy 56 pcs in total.

If a decorative pattern is planned on the wall, it must be purchased separately. The size of the drawing is indicated on the packaging. Accordingly, this value must be subtracted from total area surfaces, buy only the missing tiles.

Calculation of plastic corners

The use of such corners speeds up the process of laying tiles and allows you to hide small errors made during measuring or cutting tiles. They are installed in internal and external corners, at the junction of the wall and floor. Have different color and sizes, are sold in standard lengths of 2 m and 4 m. They are easy to work with, one side is laid with glue under the tile, and the edges go into the second side freely. This allows you to hide cut irregularities, small chips, etc.

Count it up internal corners, measure their total length. Do the same with external ones. There is no need to round anything out, they will sell it in the store standard length. These elements cost pennies, and you won’t be able to save money on them. Do the same steps around the perimeter of the bath, find out the total length. Do not forget to separately count the number of each type of plastic corner.

If possible, you can also use ceramic skirting boards for bathrooms. In addition to the length, you need to know the number of angles and their type. Professional craftsmen It is recommended to use these skirting boards to finish the junction of the sides of the bathtub with the wall.

Sum up the length and width of the bathtub, find out the minimum footage. The point is that the length ceramic borders standard, they will have to be cut to fit your size. Are being cut decorative elements on a special disc trimming machine. This professional equipment, is quite expensive. It is not economically feasible to buy for finishing one bath.

Calculation of the number of floor tiles

There is less work here, everything can be done in a few minutes. How to calculate how many floor tiles you need for a bathroom?

Step 1. Measure the two side walls of the room. There is no longer a need, the perimeter of the room looks like a rectangle, the sides have the same dimensions. In our case, the length is 3.0 m and the width is 1.5 m.

Step 2. Find out the area of ​​the room. 3.0 m × 1.5 m = 4.5 m 2.

Step 3. If you do not want to tile the floor under the bathroom, then you need to subtract its area. This can only be done in cases where the bathtub has a continuous decorative screen that hides the lower space. The dimensions of our bathtub are 1.7 m by 0.7 m, the area is 1.19 m2.

Step 4. Determine the area open area bath floor. 4.5 m2 – 1.19 m2 = 3.31 m2. Taking into account the reserve, you will need approximately 3.7 m2 of tiles.

Bathroom tile quantity calculator

Any calculation using a calculator is preliminary, as it cannot take into account all the features of your premises. For a more accurate calculation, please contact our managers when placing an order.

1. Dimensions of the room - you must indicate the dimensions of the room in meters.

2. Door size - the area of ​​this area will be subtracted from the total area.

3. Dimensions of the bathtub - you need to indicate the need to lay tiles on the sides of the bathtub and under the bathtub.

4. Layout type - there are options from three types of layout (classic, single-volume and combined).

In the case of a classic layout, the cladding is divided into two parts, which are separated by a border. In this case, the lower part has dark colors tiles, top - light colors.

A single-color cladding option assumes that all tiles are laid in the same color with the addition of decorative elements.

For a combined tile layout, several colors are used, usually three.

5. Tile dimensions must be indicated in millimeters.

7. For borders, the number of rows must be indicated. The row is located along the entire perimeter with horizontal cladding, and from floor to ceiling with vertical cladding.

8. At the very end, you need to indicate the supply of tiles you need. The recommended margin is at least 5% (for trimming, accidental chips during trimming).
