When you finish the bathroom can use different materials, sometimes quite expensive. To such materials should be attributed and ceramic tiles (porcelain tiles, tiles, etc.). That is why the actual question is how to calculate the tiles that need to be purchased to create a floor covering. When carrying out such calculations, a proven methodology is used. It can be used in repair work in kitchens, corridors and other premises.

The scheme of facing the floor with tiles.

## Calculation of quantity

Before calculating the tile, you need to determine what kind of laying will be used. Today, the flooring with ceramic granite or tiles in the bathroom can be made in the traditional way or diagonally. Despite the fact that usually the area of such premises is small, laying the flooring in the bathroom can be a serious undertaking, as it should not only be reliable and durable, but also aesthetically attractive.

**Usually, in order to calculate the tile, the following algorithm is used: the area of the bathroom is calculated, which is then divided by the dimensions of the ceramic granite. **To understand the calculation principle, you should use this example:

- the bathroom has the following dimensions: 3 m wide and 3 m long;
- dimensions of tile for laying on the floor: 0,3х0,3 m.

First of all, the dimensions of the bathroom are calculated: 3 x 3 = 9 m^{2}.

Then it is necessary to find out the area of each ceramic granite element: 0.3 x 0.3 = 0.09 m^{2}.

The scheme for calculating tiles on the floor.

To calculate the tile, the area of the room needs to be divided into the dimensions of the material: 9: 0.09 = 100 pieces. To the resulting number you need to add a few items in reserve: 100 + 5 = 105 pieces.

Thus, in order to lay ceramic granite on the floor in a traditional way, 105 elements will be required.

When decorating the room with ceramic granite diagonally, the number of elements is determined in a similar way. But here it is necessary to take into account that the amount of material bought in reserve should be large, because many elements laid down by the diamond will be further clipped.

As a rule, in this case, experts, in order to calculate the tile, multiply the result of calculations by 15%. For example, to finish the room in 9 m^{2} you need 100 pieces of granite. The calculations are: 100 x 15% = 15 pieces. That is, to finish the bathroom in a diagonal way, you should purchase 115 pieces.

In the event that the elements have complex patterns that must be taken into account when laying out, you can insure yourself and buy a few more pieces. If ordinary porcelain stoneware is used, more is not recommended, because the trimmed parts will also be used in the work.

If we talk about calculating the required number of tiles on the walls, then we use a similar calculation algorithm. First, the parameters of the walls are determined, then their area is calculated. From the received product the sizes of a doorway are subtracted. The remaining number is divided by the area of one element of the tile.

## Counting glue

Great value in the purchase of material for bathroom finishing has information on the amount of glue that is needed to create a high-quality and reliable floor covering.

Table of calculation of glue for laying tiles.

If you calculate the tiles on the floor, you can, focusing only on the area of the room and the way of laying, many factors are important here:

- flatness of the base;
- the state of its surface;
- the sizes of a tile;
- thickness of the adhesive.

If the base has a perfectly flat surface, the consumption of the adhesive will be minimal. The larger the size of the ceramic granite elements, the greater the amount of glue required. Usually all the information can be read in the manufacturer's instructions on the package with the mixture.

After reading the information, you can calculate how much the composition will be required for finishing works. For example, the manufacturer indicated that the packaging of the mixture is designed for an area of 10 m^{2} with a layer thickness of 3 mm. This means that for finishing the bathroom with a size of 9 m^{2 }one package is enough. If it is necessary to level the flooring and make a layer of substance thicker than 3 mm, you should purchase 2 packs of glue.

The same way of determining the volume of purchased adhesive should be guided and when finishing the wall overlap. The walls are uneven much more often than the floor, and this must be taken into account when purchasing the mixture.

Using the information provided, you can easily find out how to calculate the tile yourself and buy the required amount of adhesive. This will save money from the family budget and at the same time eliminate the need to purchase material in case of its shortage.
