How to correctly calculate the number of tiles, ceramic tiles in the bathroom

People who at least once in their lives were engaged in laying tilesin the bathroom or any other room, they know how laborious this process is. And it's not even the laying of tiles on the floor and walls, but in carrying out preliminary measurements and counting the materials required for styling. While calculating the amount of materials needed for repair in the bathroom, it is important not only to correctly measure the area to be covered with the tile, but also to calculate the stock of materials.

You may ask why you need a stock of tiles. And its necessity is that in the case of carrying out a large number of operations related to cutting, the probability of obtaining a marriage is much greater. The quality of the material also has an effect on the consumption of the tiles. Experts say that the most acceptable amount of material for stacking is 10% of the required minimum. How to properly calculate the materials for laying the tile in the bathroom, you will learn in this article.

First of all, when calculating the required amount of material, it is necessary to know the area of ​​all the surfaces to be treated in the bathroom. This is a fairly simple process that requires a responsible approach.

The algorithm for calculating the working surface area is quite simple:

• To calculate the total area of ​​the walls, it is first necessary to measure the length of each wall, add all the values ​​and multiply by the height of the ceiling. The result is the total area of ​​the room.
• Be sure to determine the dimensions of the doorway and window. And if there are also niches and ledges in the bathroom, then their dimensions also need to be known.
• After that it is necessary to subtract the value of the area of ​​doorways and windows from the total area of ​​the entire bathroom. Thus, we get the value of the surface area to be covered by the tile. In order to calculate the floor area of ​​the bathroom, it is necessary to multiply its length by the width. In the case of complex configurations, the area of ​​the floor can be divided into simple figures. Having divided a premise into more simple figures, having calculated their area, it is possible to define the general, having summarized the received results.

After all the measurements are made it is necessary to determine the way of laying the tile units. There are several basic ways of laying tiles on the walls and floor of the bathroom. The choice of this or that method depends on what kind of final effect you want to achieve as a result of repairing and tiling the bathroom.

Let's consider the basic ways of tile laying.

This way the tiles are laid in rows under each other in parallel to the walls and corners. In addition to simplicity, this method is also very economical, there is very little waste and scrap in the process of laying.

Diagonal - more complicated way of laying. The first row is formed from diagonally cut slabs, and the seams between the slabs are thus positioned perpendicularly and at an angle of 45 degrees to the wall.

There are several more options for laying tiles, but they are used much less often, require a high level of professionalism of the master and a great deal of time and materials. For example, the carpet method of laying floor tiles.

The most accurate calculation of the number of tiles needed for repair in the bathroom is to follow a few simple rules:

1. First of all, you need to determine the necessary wall parameters - width, length and height. The size of the doorway, the size of the niches and projections, should be measured and subtracted.
2. Next you need to select the desired size of the plate. It should be borne in mind that if you use tiles from different manufacturers or from different collections, it may also not coincide in size.

When the dimensions of the room are determined and the way of laying is chosen, calculate the area to be tiled with. At the same time, it will be superfluous to calculate the quantity, the required tiles, in pieces.

walls Let's consider an example of calculating the required number of wallboard slabs for the bathroom walls:

1. We count the number of tiles that fit along the length and height of the wall in 1 row.
2. The values ​​are multiplied and we get the number of tiles for the decoration of the wall.
3. Add at least 10% for unforeseen events.

A detailed example is given below. It also takes into account the area of ​​the doorway.

1. Measurements and calculations for greater accuracy should be made for each of the walls separately. For example, the height of one of the measured walls is 270 cm., And the tile you chose is 30 cm high, dividing 270 by 30, we get 9 tiles in one row.
2. Similarly, we learn the number of wall tiles along the width of the wall. The rounded values ​​should be rounded up.
3. Number of tiles obtained separately in length and width, multiply, thus obtaining the total number of tiles for each wall.
4. Also it is necessary to take into account the sizes of borders if the tile will be stacked according to a method with a border.
5. Having a doorway a little complicates the calculation. The height of the doorway, assume it is 200 cm, we divide by the height of the selected tile, for example, 30 cm, round down and get the number of tiles in height, equal in this case 6.
6. In the same way, we find the number of tiles onthe width of the doorway, and then the total number of tiles that can fit into this opening and take them away from the total number of tiles required for the entire wall.

The number of floor tiles must also be pre-calculated. To do this, we measure the length of the floor, for example, it is 170 cm, and the width, for example, is 150 cm, and the size of one floor plate is 33 by 33 cm.

The number of tiles in width, in this case 5 pieces, is determinedby dividing the width of the floor by the width of the plate with rounding to the larger side. Also we find the number of plates, which is required by length, in this case it is 6 pieces.

We multiply the results among ourselves and add about a couple of pieces as a stock. If we determine the number of required floor slabs by dividing the floor area by the area of ​​one tile, we will get a shortage of working material in the amount of 6 pieces.

The calculation methods described above are used for laying the facing tiles by the "seam in the seam" method. In order to calculate the required number of tiles most accurately with a diagonal lining, you need to depict it on a piece of paper in a box or in millimeter paper.

Each wall is represented separately and we draw the necessary drawing. Then just count the number of whole and cut slabs. If two cut pieces can be obtained from one tile, then only one tile should be indicated in this case. After the calculations, add about 15% of the stock and get the total number of tiles for this method of laying.

In order to calculate the necessary number of curbs and pencils, you need to know the size of the curbs and pencils used, as well as the perimeter of the room without taking into account the size of the doorway. The quantity is determined by dividing the perimeter of the room by the length of one element used for laying. During calculations, note that pencils will need twice as much because they fit on both sides of the curb.

The amount of tile adhesive will depend on the condition of the walls and floor, as well as the size of the selected tile unit. If the surface intended for facing is sufficiently flat, then the consumption of the glue will be small. The consumption of glue will increase significantly with a large size of the facing tile, because the adhesive layer will need to be made thicker. Average data on the consumption of glue is always indicated on the packaging, so they should be guided first.

To find out the required amount of grout for intertitic joints in kilograms, you should divide half the perimeter of one product into its area and multiply it by the width. The resulting number must also be multiplied by the width of the seam( from 1.5 to 3 mm) and to the depth, which is usually taken equal to 1.5 mm. Thus, the value of the grout weight is obtained for a surface treatment of one square meter.

In order for the bathroom repair to pass easily it is necessary to be first of all attentive in the calculations. Protect yourself from unnecessary troubles and problems - buy a tile in sufficient quantities, it is purchased about 10-15% more than necessary in accordance with the calculations. It should be remembered that with diagonal, figured and carpet laying, tiles will require significantly more than when stitching in the seam and in the runaway. When the bathroom has a complex geometric shape, niches and ledges, their dimensions must also be taken into account. In the number of tiles, it is better, of course, to make a mistake in the big direction, but if there are not enough pieces, it is not a fact that the purchased copies will be from the same lot, and will not differ in color and texture from the previously acquired tiles.

In our age of information technology, there are many different programs and online services to determine the amount of tiles required for repair. Online programs are much more convenient, because they do not need to be downloaded from the Internet, they are freely available for online use. Similar programs are easy to use and they produce fairly accurate calculation results. Very interesting are also 3-D programs, which can not only calculate the number of tiles, but also show how the chosen facing design will look. Also, such programs will help to calculate the number of decorative elements.
