Calculation of bathroom tiles, area calculator

The most versatile and reliable wall covering in the bathrooms remains tile. That is why the ability to independently calculate the tile for the bathroom is a necessary skill for anyone who is engaged or is just planning to do repairs.

There are two types of independent calculations of the number of tiles needed. Both are simple - even a novice can handle it, although it will take a little time.

• Initial calculation - based only on the surface area. It must be carried out to determine an approximate budget for materials. If the desired amount is known, it will help to find out if it is enough to buy the selected tile.
• Detailed - based on the sketch, taking into account the layout, seams, etc.

Initial calculation (convenient calculators)

The methodology for this calculation is simple: you need to calculate the total area of ​​the walls.

All you need is a tape measure and a calculator.

• First, we measure the height of the ceiling.
• Now you need to find the perimeter of the room - the sum of the lengths of all the walls. We measure them and add up the indicators.
• We calculate the area of ​​the walls of the bathroom, for this we multiply the perimeter by height.
• The resulting area is divided by the area of ​​one tile (length times the width) and we get the number of elements needed to surface the surfaces.

Example of initial calculation:

The bathroom has 4 walls, the length of the short one is 2.43 m, the long one is 3.7 m.
The height of the room is 2.66 m.

We consider the perimeter of the bathroom, adding the lengths of all the walls:

Perimeter = (2.43 + 3.7) × 2 = 12.26 m

We consider the area of ​​the walls:

Area = 2.66 × 12.26 = 32.61 sq. m

Round to a larger integer, we get 33 square meters. m

It’s easy to calculate the desired area, taking into account the doorway, our convenient calculator will help.

Therefore, in order to clad the walls in this bathroom, you need 33 square meters. m tile.

Let's count the number of tiles in pieces for this area.

Let the product size be 20 × 30 cm or 0.2 × 0.3 m.

The area of ​​one cladding element is 0.2 m × 0.3 m = 0.06 sq. m

Then the number of tiles for gluing the entire room in this example will be:

33 sq. m: 0.06 sq. m = 550 pieces.

For a quick calculation, just enter the data in the form below.

You can calculate the number of packs of tiles, if this is more convenient in a particular case. For packaging, the manufacturer and seller usually immediately give the total area of ​​the material in it. Therefore, we simply divide the calculated wall area by the area of ​​the tile in the pack and get the number of packages required for facing the bathroom.

The calculation is approximate and does not take into account trimming at the corners of the room, gaps in gluing and decor.

Detailed calculation: sketching

For a detailed calculation, you need a sketch of the bathroom. To compile it, you need to consider:

• what tile pattern will be on the surfaces;
• places without tiles (for example, behind the bathroom);
• layout option.

The most popular tile patterns:

1. One type of tile, without decor.
2. Vertical and horizontal stripes.
3. Chaotic inserts of piece decor on a tiled background.
4. Using the finished panel.
5. Breakdown of walls into color blocks (for example, the top of one shade, the bottom of another).

Places you can skip when laying tiles:

• behind the bath;
• behind the furniture;
• behind the mirrors. Especially if you plan only a mirror cloth, which is usually glued to an uncoated surface.

Economical option

Tile can only be faced with a wet zone, i.e. the place of direct contact of surfaces with water is near the bathroom or shower. The remaining walls are painted with specialized resistant paints.

Plus, in the selective lining is obvious - financial savings. Each square meter is not only the price of the tile itself, but also the cost of work and supplies. The downside is that to make a permutation will not work, only with the next repair. The decision is always individual and depends on the budget and features of a particular room.

Layout Types

When making a sketch, you need to choose one of the tile layout options, which can be as follows:

• Seam to seam, or direct layout. This is the traditional, most economical way. The tile is arranged in even rows, each next joins the previous one at an angle of 90 degrees both vertically and horizontally.
• Diagonal. Finishing elements are not placed at right angles, but at a slope of 45 degrees. The most expensive layout for the consumption of tiles, since it turns out a lot of scraps.
• Stacking with offset or “slip”. It looks like a straight line, but each row is offset from the previous one, usually half the size of the trim element.

Other types of layouts (herringbone, modular and others) are much less common than the three presented.

Draw a diagram for each wall

After drawing up the sketch, you can proceed to the final calculation. To do this, you need to make a diagram of each wall, which is planned to be tiled.

The scheme should include:

• the length of the wall and its height;
• places where there will be no tile, indicating the size of these areas;
• decorative inserts.

You will also need values ​​such as:

• length and width of elements;
• joint width.

Calculation for direct layout

We count how many tiles stand in a row.

To simplify the calculations, immediately increase the size of the elements by the width of the seam. For example, the tile has dimensions of 35 × 25 cm, and taking into account the seam width of 3 mm, the parameters are 35.3 cm × 25.3 cm.

Consider an example:

Let the wall length (DS) be 235 cm. Tiles will be laid out vertically, its width (ШП) - 25.3 cm.

DS: ШП = 235 cm: 25.3 cm = 9.28 pcs.

We round to a larger integer value - for laying one row you will need 10 pcs.

The calculation is similar in height:

The height of the wall (BC) is 260 cm, the length of the cladding element (DP) is 35.3 cm.

Sun: VP = 260 cm: 35.3 cm = 7.4 pcs.

We round up, we get 8 pcs.

Thus, for facing a surface of 260 × 235 cm with a tile of 25 × 35 cm, you will need:

The number of tiles in a row × the number of elements in height = 10 × 8 = 80 pieces.

Similar calculations are performed for each wall.

After counting the number of tiles, taking into account the layout, a grid of rows of columns is applied to the sketch directly on top of all available designations.

How to take into account the areas without tiles in the calculations?

Take for example the door. We turn to the diagram of the wall with the grid applied.

Thanks to the real calculation of the location of the elements immediately after applying the grid, you can see how many tiles cross the door. We count the number of integer elements that fell on the opening, and subtract them from the total number. Tiles that partially crossed the door area are not deductible.

We do the same with any area that remains unclad.

How to adjust the result based on the decor?

The simplest and most economical option is if the decor has the dimensions of a background tile. Then we replace the main elements in the calculations with decor (in rows, columns, or individually), subtracting this amount from the total.

Example:

Already calculated surface should be decor, located vertically. Its size coincides with the parameters of the main elements.

The size of the wall in the tile is 8 rows × 10 columns.

So, taking into account the decor, which will occupy one column, the main tile will be 9 columns in 8 rows, i.e. 72 elements. The decor will be presented with 8 tiles.

Do the same with the decor, located horizontally. Piece decor is simply subtracted from the total.

If decorative elements do not coincide in size with the main ones, we use the principle of calculations for areas without cladding (example with a door). We apply the decor and mesh of the main tile to the wall diagram. Then we determine how many whole products are at the intersection, and subtract them from the total number.

Calculation for the layout "Sweep"

For this method, every second row will require one element more than with a direct layout. We calculate by the method described above, and add the missing elements according to the number of rows.

Calculation for the Diagonal layout

Exact calculations for this option, taking into account the decor and omissions, are possible only according to the scheme drawn on the exact scale.

It will be correct after all calculations to additionally multiply the result by 1.1. So the error of 10% is laid. This will save you from searching for similar ceramic tiles with errors in cutting, color and other troubles.

All these rules apply to tile calculations on any surface, including the toilet and for tiles on the floor.
