A preliminary calculation will allow you to plan your renovation budget and think through the bathroom design in detail. If you correctly calculate the number of tiles, you will not have to purchase additional material during the finishing process.
To measure the room you need to use a tape measure. Most exact values can be obtained using a laser device. Having found out the parameters of the bathroom (height and length of the walls, dimensions of the doorway), you can make preliminary calculations number of tiles. The simplest option is when the room has the outline of a rectangle or square. In this case, it is necessary to measure the minimum number of walls.
If the bathroom is complex shape, it is necessary to carefully measure all protruding elements and take into account existing niches.
The results need to be recorded on the diagram, so it will be easier to calculate the materials. A drawing made to scale will also allow you to take into account all the details of the bathroom design and correctly plan the arrangement of furniture. The calculation algorithm is influenced by the type of masonry floor tiles(diagonal, rectangular, diamond, etc.).
2. Basic rules for calculating tiles
The calculation algorithm is quite simple. When calculating the exact number of tiles, you will need formulas for determining the perimeter and area of a rectangle.
To calculate the wall area we use the following formula:
Parameters A and B (width and length of the room) alternate depending on the specific area.
The perimeter of the rectangle is calculated by the formula:
P = (B + A) * 2.
Designations in formulas:
- S - area of a certain surface in the bathroom, sq.m;
- P - designation of the perimeter of the room, m;
- A - bathtub width parameter, m;
- B - length dimension of the room;
- H is the value of the wall height.
Calculation scheme:
- The total area of the room is obtained by adding square meters separate walls bathroom;
- Then, from the obtained value, you should subtract those areas that will not be laid with tiles, for example, the area of the door opening to the room or window.
In order to reduce material consumption, cladding is not done in the space under the bathtub. This option possible if installation is planned decorative screen. In this case, the height of the room for calculation is measured from the top level of the side.
Some sites provide a special calculator that allows you to determine the required volume of material for purchase. Using such programs, you can make the task easier when calculating the amount of material if tiles of different shades are combined.
3. Calculation of tiles for a bathroom with a total area of 4 sq.m.
Main dimensions of this room:
- Wall with opening - 2150 mm;
- The length of the short wall is 1900 mm;
- Doorway - 700x2000 mm;
- Room height - 2700 mm.
Dimensions of the selected bathroom tile collection:
- Wall tiles white- 500x250 mm;
- Green wall tiles - 500x250 mm;
- Decor - 500x250 mm;
- Green floor tiles - 500x500 mm.
Facing plan
Tiles intended for flooring are laid in one tone. On the wall with the door it is planned white tiles. The remaining surfaces of the walls are supposed to be done with alternating colors along vertical stripes, as well as adding decor.
Calculation of floor tiles
We determine the parameter for the area of one tile: S = 0.5 x 0. 5 = 0.25 sq.m;
- Total floor area: S = 4 sq.m;
- Calculation of the number of tile elements for the entire floor area: 4 / 0.25 = 16 pieces.
Calculation of tiles for bathroom walls
Wall decoration elements have the same format (width and height).
- One of the walls (with an opening) is covered with white tiles, let's calculate its area without the door: S = (2.15x2.7) - (0.7x2) = 5.805 - 1.4 = 4.405 sq.m;
- Area of one wall tile: S = 0.5 x 0.25 = 0.125 sq.m;
- Number of white tiles for a wall with an opening: 4.405 / 0.125 = 36 pieces (round the number to big side);
Let's consider another calculation method, which is suitable for surfaces with tiles of different colors.
- Number of tiles in width for other walls:
1.9 m: 1.9 / 0.5 = 3.8 pieces;
2.15 m: 2.15 / 0.5 = 4.3 pieces; - Number of tiles around the perimeter of three walls: (3.8 x 2) +4.3 = 11.9 pieces;
- We calculate how many elements fit in height: 2.7 / 0.25 = 10.8 pieces.
This value can be rounded down if you plan to install a stretch ceiling; - In this example the tile strips different colors oriented vertically.
Laying green tiles is planned in 8 vertical rows, taking into account decorative elements: (8 x 10.8) - 4 = 86.4 - 4 = 83 pieces; - Number of white tiles for three walls in width: 11.9 - 8 = 4 pieces.
For three walls in total: 4 x 10.8 = 44 pieces.
Final volume values of tiles for bathroom walls
White tiles: (36+44) = 80 pieces;
. Green tiles: 83 pieces;
. Decor: 4 pieces.
When calculating the number of tiles, it is better to take into account the safety factor. If the material is damaged, the remains can be used without discrepancies in shades.
There are several such methods, each good in its own way. But, from the point of view of calculation and the process itself, the simplest is invariably direct masonry.
Direct tile laying
Standard, familiar masonry, this method can be recommended for beginners.
Advice! If the ceiling in the room is low, then you should choose a high one rectangular tiles and lay it using the direct laying method. This will visually “raise” the walls.
For high-quality installation diagonally you will have to work hard. But the result is worth it. It should be noted that diagonal masonry visually hides the curvature of the floors.
Important! Laying tiles diagonally requires additional material consumption, since you will have to cut a lot of tiles, moving from the corners in the center of the room. But don’t rush to throw away the leftovers, in case they come in handy in another corner of the room.
Laying tiles in a checkerboard pattern
This option is usually used when you want to lay ceramic tiles of several colors. The resulting bathrooms are very interesting from a design point of view, worth a try.
Laying tiles with offset
This type of masonry involves shifting each subsequent row by the same distance. This option looks more elegant and you can always experiment with various inserts, for example, use small square tiles, as was done in the photo.
How to calculate bathroom tiles
So, to avoid unwanted losses, we need to take measurements of the walls and floor.
On a piece of paper, write down measurements for all the walls of the room, subtracting windows and doors. You can safely go to the store to choose the tiles you need. Measure the tiles and write down the dimensions. Now we can calculate how many tiles we need.
There are two ways to calculate - separately by length and width or by area.
Counting the number of tiles (method 1)
To calculate the required number of tiles, first, we need to take measurements of the length and width of the surface.
Now we divide the height of the wall by the height of the tile. On at this stage you should already decide how you lay the tiles, if they have rectangular shape- horizontally or vertically. If you are laying tiles on the floor, measure the length of the floor and the length of the tiles accordingly.
For example, the wall height is 2.7 m, the tile height is 0.3 m.
2.7 / 0.3 = 9 tiles
That is, 9 tiles fit in a row in height.
2.25 / 0.2 = 11.25 tiles
When the number is not an integer, we always round up, in our case it’s up to 12. We get the number of tiles by width.
9 * 12 = 108 tiles
But this is not the final number yet, since 5% of the reserve should be added to the resulting quantity:
108 * 1.05 = 113.4 tiles
We round and thus we get 114 tiles for this surface.
We also do similar calculations for the remaining walls, add up the results and have the total number of tiles per room.
We take into account the doorway and window frame
In order to obtain the number of tiles required for the wall in which the door or window is installed, we need to subtract the number of tiles that correspond to the dimensions of the door or window opening from the number of tiles on the opposite wall.
Divide the height of the opening by the height of the tile:
2 / 0.3 = 6.7 tiles
round down - 6 pcs. in height. We round down in order to subtract a smaller number of tiles and you have a reserve left.
0.8 / 0.2 = 4 tiles
We multiply the results obtained and get 24 pieces, which we subtract from the total number of wall tiles. In a similar way, we can calculate the number of tiles for a wall with a window.
We calculate by area (2nd method)
We measure the area of the floor (wall) by multiplying the length (height) by the width:
0.33 * 0.33 = 0.1089 square meters
After this, we divide the floor area by the tile area:
4.5 / 0.1089 = 41.32 tiles
As you can see, we get an approximate number of tiles, so we round up, we have up to 42 tiles.
But don't forget to add 5% for the reserve.
42 * 1.05 = 44.1 tiles
We round up in this way, for laying tiles on the floor we get 45 tiles.
Advice! Sales consultants prefer to calculate using the second method - by area.
Any work related to renovation of an apartment begins with the choice of room design and selection necessary materials to bring an idea to life. Next, you need to calculate the required amount of paint, wallpaper and everything else that may be useful. Sometimes novice craftsmen have a very important question - how to calculate the tiles for the floor? Let's figure out how this is done.
IN construction stores on sale now different kinds tiles They differ not only in texture and color, but also in size - there are tiles both large and small. Among all the variety, there is sure to be an option that will suit the apartment owner both in appearance and in quality. But it is not enough just to choose a tile in accordance with its decorative characteristics; you also need to correctly calculate the quantity required for finishing a particular room.
Previously, tiles were often bought for future use, since the material was quite scarce. Now you can safely buy only the quantity that is needed at the moment. This allows you to save cash and spend it on some other types of materials that may be useful during renovation. Moreover, you can even count the number of tiles with an accuracy of one piece.
Advice! When purchasing such a fragile material as ceramic tiles, you should always have a small supply. It will be needed in case during transportation or directly during repair work some of the tiles will be damaged. Damaged elements cannot be used to decorate the premises.
Cover the walls with wallpaper, decorate the floors with laminate or self-leveling floors much easier than laying ceramic tiles. Therefore, the main advice for a beginner is that you need to purchase tiles with a small margin. Firstly, the reason for this is that the material is fragile and can easily be broken with one careless movement. Secondly, tiles, even in one batch, may differ in color or texture, or have a somewhat non-standard shape.
The correct calculation of the number of tiles is the determination of the required number of elements for finishing a specific place in the house, subject to a minimum error or rounding the required number up. It is in this case that it will be possible to avoid the fact that there is not enough material and you will have to go to the store again in search of the missing elements. The number of tiles is never determined by eye.
Despite the fact that doing the calculations seems to be a fairly simple procedure, there are some subtleties here. For example, it is important to consider the size of the room where the renovation is being carried out, the chosen type of tile installation, as well as the shape and dimensions. It is also worth remembering that some elements will have to be trimmed, that is, they will not be used whole.
Advice! The floor area located under the bathtub can not be counted when determining the number of tiles. It won’t be visible there anyway, but you will be able to save a lot of money on purchasing ceramics, since this material is not cheap.
How to calculate floor tiles - basic methods
You can determine the required number of tiles using one of several methods. They are applicable in all cases, even if the room where the floor is decorated has non-standard geometry. Of these, the one that seems most convenient to the master is selected. Let's get acquainted with methods for calculating the number of ceramic elements.
Important! To carry out calculations, you need to already know what size tiles will be laid in the room. And here it is important to take into account the chosen masonry pattern, as well as whether there is any pattern on the ceramic elements themselves.
By room area
The most understandable and familiar method is to determine the consumption of tiles in square meters, that is, by the area of the room. This method is ideal for laying ceramics of the same color, the same size, as well as in the case of simple or diagonal laying or offset.
First, the area of the room is determined. The easiest way to identify it is if the room has a geometric correct form- square or rectangle. In this case, the length of the room is simply multiplied by the width value. Measurements are taken of sufficient length with a tape measure along the walls of the room.
Next, the resulting value - the area of the room - should be increased by about 10%. This will allow you to make the necessary supply of material (10% can be added after all calculations have been made). The final value is divided by the area of one tile (this is also the length and width of the ceramic product, multiplied by each other) - the result is the number of elements that will be required for the work.
If it is necessary to cover the base with tiles, it is enough big size, then you can count the tiles in packs. To do this, you need to know how many square meters the coating packed in one box will cover. Then the area of the room with a margin can be divided by the area of the covering laid in one pack - the result will be the number of boxes of tiles.
On a note! If the final value in one case or another turns out to be fractional, then it is always rounded only up.
A more accurate calculation of the area can be made if you count the tiles individually. If the room has complex geometry, then you will have to tinker with the calculations. For example, you can conditionally divide it into correct geometric figures and find out the area of each of them, then add the values and get the number, equal to the area the entire floor in the room. You can also use various geometric formulas that were studied in school.
Calculator for calculating the area of a quadrangular room
When starting to calculate the number of tiles, you should decide on the type of installation, color scheme, the need for adjustment to the drawing, the use of additional decorative elements, finishing area.
Popular types of floor tile installation:
- standard. The material is located along the walls;
- diagonal. The tiles are laid at an angle of 45°C.
- diagonal chess. This method laying uses ceramics of different colors, while alternating tiles.
Types of laying wall material:
- straight. The elements begin to be laid parallel to the floor.
- straight with curbs. A narrow or wide border can be used.
- checkerboard (diagonal or normal direction).
- diagonal.
How to calculate tiles for a bathroom? First of all, you should choose the type of installation. This will allow you to correctly determine the material consumption (for example, when diagonal laying numerous tile trims are made; when adjusting according to the pattern, the edges of the tile are trimmed).
General rules for calculating tiles:
- Measure the width and length of the walls of the room that will be used for finishing, and also take the dimensions of the floor. Subtract the area of the door (bath) from the area of the wall in which the door is located or the bathtub is installed.
- Check the tile dimensions. For the floor it can be tiles 30*30, 40*40, etc., for walls - 20-30, 25-33, etc.
- Calculate the area of the cladding (in square meters).
- Divide S of the surface by S of one tile and get the amount of material in pieces.
- Add 5% to the resulting number (reserve for trimming material).
- Method I
Tile laying will be done in a standard way tiles measuring 33*33 cm. Find the number of tiles in one row - divide 150 cm (width) by 33 (the length of the side of the tile) and get 4.54 (the number of tiles in one row in width). After rounding we get 5 pieces. With a floor length of 170 cm, we find the number of rows - divide 170 by 33 and add 1 piece for reserve. We multiply the resulting quantity by the number of tiles in one row and get the result - 31 pieces.
- II method
If we counted ceramics not individually, but by floor area, the error would be quite significant. Surface area 1.7m*1.5m=2.55 m2. Tile area 0.33*0.33=0.11 m2. We divide one value by another and get 24 pieces (with rounding), add a margin of 5% - 2 pieces and we get 26 pieces. In the end, we would be 5 tiles short. When counting piece by piece, we took into account the trimming of the plates that will be done during installation.
Calculation of tiles for bath walls
To calculate, we need the width, length and height of the walls. For example, the dimensions of the ceramics are 20*30 cm, while the border is 8*20 cm. The height of the room is 2.7 m. We determine the number of tiles for each wall separately and sum up the resulting numbers.
You can simplify the calculation if you first calculate the perimeter of the room. Then the width of the door (0.6 m) should be subtracted from it. As a result, we get – (1.5+1.7)*2-0.6==6.3. In our example, the bottom of the walls will be lined with dark-colored ceramics, the top will be light-colored, and the border will be between them. We divide the height of the walls into 3 sectors and get 2.7-0.08 (border) = 2.62 m, while the height of the bottom will be 1 m, the light top will have a height of 1.62 m.
We calculate the amount of dark tiles as follows: 6.3*1=6.3 m2. Considering that the area of 1 tile is 0.3*0.2=0.06 m2, we determine the quantity - 6.3/0.06=105 pieces. We increase by 5% and get 110 pieces.
We find the amount of light tiles in a similar way: 6.3 * 1.62 and we get 10.206 m2. We divide 10.206 by the tile area of 0.06 and get 170.1 pieces. We add 5% to the stock, and in the end we get 179 pieces. We determine the amount of tiles that will be used for laying above the door 0.6 * 0.7 = 0.42 m 2. We divide the resulting value by 0.06 (S tiles) and get the quantity 7 pieces. Total: 186 units of light tiles.
We calculate the border as follows: 6.3/2 = 31.5. We round the resulting figure to 32 pieces.
How to calculate tiles for a non-standard installation option?
Often to create exclusive interiors are used complex ways masonry - “herringbone”, “staggered”, etc. In order to correctly determine the amount of material, you should display on a sheet of paper (millimeter or squared) on a convenient scale the area that will be processed. Taking into account the scale, draw a diagram of the masonry, marking solid elements and those that will be trimmed with different icons. This will allow you to calculate the tiles for the bath as accurately as possible. Once the amount is determined, increase it by 10%.
Calculating the amount of glue and grout
The amount of glue required for laying ceramics depends on factors such as the smoothness and condition of the wall and floor surfaces, the thickness of the adhesive layer, and the size of the tiles used. The smoother the walls are, the lower the glue consumption. The larger the surface of the tile, the more glue is applied. For average plastered walls, you can calculate the amount of glue based on the information provided by the supplier on the bags with the composition.
At the final stage of laying the tiles, we grout the seams. For these purposes it is purchased special composition(grout) matching the tone of the main color of the coating; a contrasting option is also possible (for example, white grout is matched to a black tile).
To calculate the amount of grout, you need to determine the volume of space that needs to be filled. The depth of the seam is equal to the thickness of the tile multiplied by 1.5 (taking into account the shrinkage of the material), the width of the seam can vary between 1.5-3 mm. The amount of grout is calculated as follows: 1/2 the perimeter of 1 tile should be divided by its area and multiplied by the thickness. We multiply the resulting result by 1.5. As a result, we get the mass of grout in kg required to lay 1 square meter of ceramics.
Example, the joint width is 2 mm, while the area of 1 tile is 0.04 m2. For 3.5 m2, 1 kg of grout is enough.
This question is one of the main ones: how many tiles are needed for work, that is, how to calculate the number of tiles for the floor. Here we need calculations to accurately determine required quantity tiles for a bathroom or other room.
To do this, measure the length of the room and divide by the length of one ceramic tile. Also measure the width of the room and divide by the width of the tiles. Then multiply the two results obtained, after which you will get the required number of tiles for a given room.
1 option for calculating the number of tiles
For example, room length 3 meters and width 2 meters. Ceramic tile size 200x150 mm. It is advisable to convert to one unit of measurement:
- Room length 3 meters = 300 cm, and the width 2 meters = 200 cm.
- Tile 200 mm = 20 cm, and the width 150 mm = 15 cm.
- Now all that remains is to calculate:
- Divide the length of the room by the length of the tiles = 300/20=15 ;
- Divide the width of the room by the width of the tiles = 200/15= 13,3 ;
- Let's multiply the two obtained indicators = 15*13,3= 200 .
Happened 200 tiles for this room.
Option 2 for calculating the number of tiles
There is another calculation option that may be easier for you than the previous one. First you need to calculate the area of the room and the area of one tile. And then divide the floor area by the area of the tiles.
Let's look at it with an example. Let's take the indicators from option 1. Room length 3 meters and width 2 meters. Ceramic tile size 200x150 mm.
Here we convert the tile size to meters:
200 mm = 0.2 meters
150 mm = 0.15 meters
Floor area in the room: 3 m * 2 m = 6 m 2
Area of one tile: 0.2 m * 0.15 m = 0.03 m2
The floor area is then divided by the area of one tile: 6 m 2 / 0.03 m 2 = 200 pcs. That is, we will need 200 tiles.
