Calculation of tiles online. How to calculate the number of bathroom tiles. What if the room has a complex shape
Any repair begins with the purchase of the necessary materials. To carry out facing work, it is important to make the correct calculation of tiles for the bathroom. Moreover, the possibility of error must be excluded, since if there is a shortage of material, work will have to be stopped and additional tiles purchased. If the product was sold in limited quantities, then you may not find the same tile. It is also undesirable to purchase extra facing material, since during the repair there is not enough money to scatter them thoughtlessly. How to calculate: how many tiles do you need exactly? In principle, there is nothing complicated in the calculations. You just need to carefully measure the room, apply the measurements obtained to the schematic drawing of the bathroom and, armed with a calculator, perform several mathematical operations.
How to calculate the number of floor tiles
The length and width of the bathroom is measured with a tape measure, and the results are recorded on a piece of paper. Do not rely on memory, which can fail. In addition to these values, you need to know the dimensions of the floor tiles that you decide to buy for finishing the room. Assume that a square floor tile with a side equal to 33 cm (0.33 m) is selected for laying. Let the dimensions of the bathroom be 1.7 by 1.75 m.
There are two ways to count:
- We calculate the floor area by multiplying the length by the width of the bathroom: 1.7 * 1.75 \u003d 2.975 (m 2). Next, we calculate the area of one tile by multiplying the sides: 0.33 * 0.33 \u003d 0.1089 (m 2). Then we divide the floor area by the tile area: 2.975: 0.1089 = 27.3 (pcs.). As you can see, the result is approximate, so we round it up and get 28 tiles. However, always add 5% to the calculated number for the stock. In our case, we need to add two tiles (28 * 0.05 = 1.4 - rounded up to two). Thus, for the bathroom floor we buy 30 tiles.
- We calculate the number of tiles laid in length. To do this, we divide the length of the bathroom by the side of the tile: 1.75: 0.33 \u003d 5.3 (pcs.). We carry out the same action with the width of the room: 1.7: 0.33 \u003d 5.15 (pcs.). This result is rounded up to 5.2. The resulting results must be multiplied: 5.3 * 5.2 = 27.56 pieces, after rounding we get 28 pieces. We also add 5% and get the same result as in the first method, namely: 30 tiles.
How to calculate tiles for bathroom walls
To calculate the number of tiles needed for cladding the walls of the bathroom, you must also measure the height of the room. The dimensions of the selected tile are 20 by 30 cm, the curb - 8 by 20 cm. Let's say in our example the height of the bathroom is 2.7 m. You can calculate the number of tiles for each wall separately, and then add the resulting values. To reduce the number of operations, you need to calculate the perimeter (the sum of all sides).
Moreover, from the perimeter it is necessary to subtract the width of the doorway, which in our example is 0.6 m. We get: (1.75 + 1.7) * 2-0.60 \u003d 6.3. If the bottom of the walls will be finished with dark tiles, and the top with light ones, and a curb row will pass between them, then we divide the total height into three parts. We get: 2.7 - 0.08 \u003d 2.62. Let the height of the dark "bottom" be equal to 1 m, then the height of the light "top" remains 1.62.
- We calculate the number of dark tiles: the area of the dark strip is 6.3 * 1 \u003d 6.3 (m 2). The area of one tile: 0.2 * 0.3 \u003d 0.06 (m 2). We divide the values: 6.3: 0.06 \u003d 105 (pcs.). Add 5%: 105 * 0.05 = 5.25 (pcs.). Round up to five. As a result, we get 110 dark tiles.
- We calculate the number of light tiles: the area of \u200b\u200bthe light strip is 6.3 * 1.62 \u003d 10.206 (m 2). The area of the tile has already been calculated: 0.06 (m 2). We divide the area: 10.206: 0.06 = 170.1 (pcs.). Round up to 171 and calculate 5%: 171 * 0.05 = 8.55. You can stock up on 8 pieces. But we must not forget about the space above the door: 0.6 * 0.7 \u003d 0.42 (m 2). Divide this number by the area of the tile and get 7 tiles. As a result, we need 186 light tiles.
- We calculate the number of border elements: 6.3: 0.2 = 31.5 (pcs.). Round up to 32 pieces.
Important! If you plan to use decorative inserts sold by the piece, then the number of main tiles is reduced accordingly.
There are several such methods, each in its own way is good. But, from the point of view of calculation and the process itself, the simplest is invariably straight masonry.
Direct tiling
Standard masonry is familiar to everyone, this method can be recommended to beginners.
Advice! If the ceiling in the room is low, then you should choose a high rectangular tile and lay it in a straight masonry method. This will visually "raise" the walls.
For high-quality diagonal styling, you will have to sweat. But the result is worth it. It should be noted that the diagonal masonry visually hides the curvature of the floors well.
Important! Laying tiles in a diagonal way 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 do not rush to throw out the leftovers, suddenly they will be useful to you in another corner of the room.
Laying tiles with a checkerboard pattern
This option is usually used when they want to lay ceramic tiles in several colors. It turns out very interesting in terms of design bathrooms, worth a try.
Offset tiling
Such masonry implies the displacement of each subsequent row by the same distance. This option looks more elegant and you can always experiment with a variety of 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 measurements for all the walls of the room, subtracting windows and doors. You can safely go to the store to choose the tile you need. Measure your tiles and write down your measurements. Now we can calculate how many tiles we need.
There are two ways to calculate - separately by length and width or by area.
We count the number of tiles (1 way)
To calculate the required number of tiles, for starters, 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. At this stage, you should already decide how you lay the tile, if it has a rectangular shape - horizontally or vertically. If you are laying tiles on the floor, measure the length of the floor and the length of the tile accordingly.
For example, the height of the wall is 2.7 m, the height of the tile is 0.3 m.
2.7 / 0.3 = 9 tiles
That is, in height we have 9 tiles in a row.
2.25 / 0.2 = 11.25 tiles
When the number is not an integer, we always round up, we have up to 12. We get the number of tiles in width.
9 * 12 = 108 tiles
But this is not the final number yet, since 5% of the stock should be added to the amount received:
108 * 1.05 = 113.4 tiles
We round and thus we get 114 tiles on this surface.
We also do similar calculations for the rest of the 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 get the number of tiles needed for the wall in which the door or window is installed, we need to subtract the number of tiles from the number of tiles on the opposite wall, which falls on the dimensions of the door or window opening.
Divide the height of the opening by the height of the tile:
2 / 0.3 = 6.7 tiles
round down - 6 pcs. in height. Rounding down, in order to subtract a smaller number of tiles and you have a margin.
0.8 / 0.2 = 4 tiles
We multiply the results 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 (2 way)
We measure the area of \u200b\u200bthe floor (wall) by multiplying the length (height) by the width:
0.33 * 0.33 = 0.1089 square meters
After that, we divide the floor area by the tile area:
4.5 / 0.1089 = 41.32 tiles
As you can see, we get the approximate number of tiles, so we round up, we have up to 42 tiles.
But do not forget you need to add 5% to the stock.
42 * 1.05 = 44.1 tiles
We round it up in this way, for laying tiles on the floor we get 45 tiles.
Advice! Sales consultants prefer to count in the second way - by area.
Why and how to calculate the tiles in the bathroom? This is necessary to purchase the required volume of building materials: you will not overpay for unused material, and the money saved can be spent, for example, on buying tile adhesive.
Calculation of tiles for bathroom walls
- We calculate the area. Measure the perimeter of the room and multiply it by the height of the walls. For example, the height of the room is 2.7 m, the width is 2.5 m, the length is 3 m. Find the perimeter: 2.5 + 2.5 + 3 + 3 = 11 m. Multiply the perimeter by the height: 11 × 2.7 = 29, 7 m2. From this number, the area of \u200b\u200bthe door and windows, if any, is subtracted. Suppose, after subtracting, an area of \u200b\u200b28 m2 was obtained.
- Find the area of 1 tile. For example, the dimensions of one tile are 0.3 × 0.2 m. Then its area is 0.06 m2.
- Find out the number of bathroom tiles. The area of the walls is divided by the area of one tile: 28 / 0.06 = 467 pieces. 10% stock is another 47 pcs. The total number is 514 tiles.
How to calculate the number of tiles per floor
The mathematical calculation of the number of tiles per floor is similar to the algorithm described above:
- Finding the floor area.
- Divide the floor area by the area of one tile.
Common Questions
- How to calculate the number of bathroom tiles if it is placed diagonally on the floor or wall? In this case, the calculation algorithm is no different.
- What to make a margin when calculating bathroom tiles? The allowable stock of a tile from its calculated quantity is 10%. Buying a larger volume of tiles is unreasonable for reasons of economy, less is risky, because you also need to take into account the seams for tile grout.
- How to calculate how many tiles are needed in the bathroom if the floor area is partially covered by a bath or shower? Just subtract it from the total floor area.
As you can see, simple calculations allow you to find out how many tiles you need in the bathroom. The calculation principle is also relevant for
August 18, 2016Specialization: master of interior and exterior decoration (plaster, putty, tile, drywall, wall paneling, laminate, and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all the necessary types of work.
To begin with, you can use the bathroom tile calculator, but I will warn you right away - this will give you the most inaccurate result. And all the flood that such programs are not able to take into account the nuances.
However, making such calculations yourself is easy and simple, and they will be the most accurate, up to one unit of a tile (although a couple of extra pieces will still be needed in reserve). I suggest you study a short course of study, more precisely, an understanding of the very principle of calculation.
Calculation of tiles according to the size of the room
What to Consider
In a room with the same quadrature, a different amount of material may be needed. Therefore, the question of how to calculate the number of tiles in the bathroom also depends on the number and location of plumbing units and pipelines.
There are several nuances that you should pay attention to, since it is most accurate to calculate how many tiles you need in the bathroom, you can only take them into account. First of all, in order to understand how to calculate the area of \u200b\u200ba bathroom for tiles, you need to accurately determine the installation of plumbing fixtures and the size of the tile itself.
Let's get started with this:
- the very first thing you need to consider is how the tile will look in those places that are most visible. As a rule, they are located under the ceiling (top row), as well as above the bathrooms, for example, above the bathroom;
- but here the catch is that you can set the height of the same bath arbitrarily, but changing the height of the ceiling is much more difficult. Therefore, the focus should be on the level of the ceilings;
- under the ceiling, even if they are suspended, it is desirable to have a whole, uncut row. So, the calculation of the number of pieces vertically should come from there;
- this means that we measure the number of tiles from the stream to the first row (usually, these are 8 pieces of tiles 200 × 300 mm), and leave the bottom row for later;
- but it also happens when you can fit into an integer number of tiles, then you can also make an uncut row above the bathroom, as shown in the bottom photo;
- on the walls where the bathroom will be pressed, the calculation of the tile for the bathroom should not be done - you can leave an empty space there, since no one needs cladding in an inconspicuous place;
- the same can be said about the tiles on the floor - tiles are not needed under the bathroom and no instructions require them to be installed there. The bath fits perfectly on the screed, especially since it is easier to adjust its height ;
- some also save tiles under the cabinets, but I don’t advise doing this, it’s too “slippery place” - after all, the doors open and everything is visible there;
- another point in the question of how to calculate the tiles more economically is a shower cabin or a box, although I don’t quite understand the point of installing a box in a tiled room - this is just an absurdity or a thoughtless waste of money;
- tiles are not needed under the pallet, but it depends on the owner’s desire (the area is small), but why put a box where you still need to put tiles on the walls, since they will be noticeable ?! I repeat once again - this is absurdity and it is unlikely that anyone will find arguments to convince me otherwise;
- one more thing, how to calculate the consumption of a tile, is the presence or absence of it on, but there usually the calculation is clean, without any resets;
- and finally, these are boxes that can be in any bathroom, although again, I believe that a large number of them is the negligence of a plumber. They are needed only where a vertical or horizontal pipe cannot be hidden in a strobe.
Calculation examples
As they say in Odessa: “What will I get from this?”. In our case, it means how to correctly calculate the tiles for a certain layout of plumbing units? Let's start with the total area.
Imagine that our area is 3.0 × 2.5 m - this, of course, is a private house, but for example there is no difference. We will take the height of the walls to the draft ceiling 2.6m, therefore, we will get the whole room 3.0 × 2.5x 2.6m. The cubic capacity will be of little interest to us, since the tiles should be counted according to the area.
Again, let's move on to abstract images and by default we will take a 200x300 mm tile, since it is used most often. We will have spacer crosses with a thickness of 3 mm (also the most popular).
I will say right away that the thickness of the seam should not be taken into account - this, of course, also applies to determining the quantity, but even the most experienced tiler can have force majeure. Any of the tiles may fall and break, or simply burst when cutting.
Then one row will require 3000/200 = 15 pieces exactly. But here, for symmetry, you need the width of the seam. This means that between fifteen pieces you will get 13 seams of 3 mm, in total, 13 * 3 = 39 mm (we consider 40 mm). This means that the extreme tiles will need to be cut 2-3 cm each, leaving 180 mm each, although their number will remain the same - 15 pieces.
Next, we move on to the vertical - everything is calculated in the same way. And if we have a room height of 260 cm (2600 mm), then we need 2600/300 = 8.6 pieces for this. That is, the first row will be slightly more than half. A little wrong!
The price of the material will decrease if we make the correct calculation:
- first, we have seams;
- and, secondly, it is not necessary to put the tiles right up to the ceiling, because there will still be floor tiles below.
Therefore, the number of copies can be reduced to 8.5 pieces, then the bottom row will go one for two. So, at the bottom you will need not 15, but only 8 pieces!
Now, let's define areas that can be skipped, especially if it's an expensive tile, like 3d. Since it is not needed under the bathroom, then its quantity can be calculated from the total quadrature. For example, let's take a bathtub with length/width/height dimensions of 1700x700x570 mm (this is an ordinary standard bathroom).
So, if we have a height of 570 mm, then the row of tiles above the bathroom will start (third row 150 + 300 = 450 mm) from 570-450 = 220 mm, that is, almost from a whole row.
We do the same with the end and side in width - we calculate the absence of tiles on this segment. If you want to tile the bathtub, and not install a plastic screen there, then you should not do such calculations - everything will remain in place.
Bathroom renovation is considered to be one of the most expensive and difficult. The complexity is due to the presence of various protrusions in the room: built-in cabinets, ducts for pipes, door and window openings, etc. Of course, calculating the number of tiles needed in the bathroom is not an easy task, but it is quite possible. The main thing is to approach this process with special care and scrupulousness. This will help you avoid overspending on repair costs.
The Internet is replete with a variety of online tile calculation programs, but still, the percentage of error in them is quite high. It is more expedient to calculate independently, excluding errors.
The first thing to do is to decide which tile is right for your bathroom. The modern building materials market offers ready-made kits.
- It should be noted that in a small room it would be appropriate to look at tiles of small sizes.
- With a low ceiling, the tile of an elongated vertical shape will visually increase the height.
- In order to exclude the possibility of slipping on a wet floor in the bathroom, you need to choose a tile with a relief.
- It is not superfluous to check the perpendicularity of the walls before laying the material. Otherwise, the laid tiles will emphasize all the shortcomings and require a large amount of glue, which will affect the amount of money spent.
Calculation of the required number of floor tiles in the bathroom
So, having decided on the choice of tiles, the first thing to do is to measure the width and length of the room. To understand how to correctly calculate the number of floor tiles, we will give an illustrative example.
Conditional data:
- The length and width of the room - 3 × 3.5 m
- The length and width of the floor tiles - 40 × 40 cm
Calculation according to the formula:
N \u003d S p / S pl. , where
N is the amount of material, in pieces,
S p - floor area, in m 2
S sq. - the area of \u200b\u200bone tile, in m 2
S sq. \u003d 0.4 * 0.4 \u003d 0.16 m 2
S p \u003d 3 * 3.5 \u003d 10.5 m 2
N \u003d 10.5 / 0.16 \u003d 65.625 m 2, by rounding it turns out 66 pieces, and taking into account marriage and battle 66 + 5% \u003d 70 pieces.
How to correctly calculate the number of facing tiles for walls
Additional conditional data:
Room height - 2.5 m
The length and width of the facing tiles - 25 × 33 cm
The length and width of the border element - 8 × 20 cm
The length and width of the doorway - 2.1 × 0.4 m
The estimated height of the dark bottom is 0.9 m
To calculate the amount of facing material, we use the formulas:
- 1. N= Sv.s./S pl, where
S v.s - the area of \u200b\u200ball walls, in m 2
S pl - the area of \u200b\u200bone tile, in m 2
- S v.s. =(H*R v.s.) -S d.p., where
H is the height of the room, in m
P v.s. - the perimeter of all walls, in m
S d.p .. - the area of the doorway, in m 2
- R v.s. =(a+ d)*2 , where
a, d - length and width of walls, in m
- Spl = a 1 * d 1 , where
a 1,d 1 - the length and width of the tile, in m 2
Calculation:
R v.s. \u003d (3 + 3.5) * 2 \u003d 13 m
S d.p. \u003d 2.1 * 0.4 \u003d 0.84 m 2
S v.s. \u003d (2.5 * 13) -0.84 \u003d 31.66 m 2
S pl \u003d 0.25 * 0.33 \u003d 0.0825 m 2
N \u003d 31.66 / 0.0825 \u003d 383.76 pieces, when rounded up we get 384 pieces. For the stock of tiles, we take into account 5% and have 404 pcs.
How to calculate the number of tiles if two colors are selected
Suppose that, according to the design, the upper part of the bathroom will be lined with light tiles, the dark one will be located below, and they will be separated from each other by border elements. Now there is not one height, but three.
When calculating, the formula N \u003d S / S pl is preserved, but transformed:
- 1. N s.p. \u003d S s.p. / S pl, N etc. \u003d S m.p. / S pl, where
N s.p. , N etc. - the number of light, dark tiles, in pieces,
S s.p. , S etc. - areas of light, dark tiles, in m 2
S pl - the area of \u200b\u200bone light / dark tile, in m 2
- H st. \u003d H-h 1 - h 2, where
H is the height of the room, in m
h 1 - the height of the dark "bottom", in m
h 2 - curb height, in m
For calculations, you will also need the perimeter of all walls minus the width of the doorway:
- P \u003d P w.s. - d, where
d - width of the doorway, in m
Number of "top" material(light tiles):
P \u003d 13-0.4 \u003d 12.06 m
H st. \u003d 2.5-0.9-0.08 \u003d 1.52 m
S s.p. \u003d 1.52 * 12.06 \u003d 18.33 m 2
N s.p. = 18.33/0.0825 = 222.18, i.e. 222 pcs. Including 5% - 233 pcs.
The number of material "bottom"(dark tile):
The calculation is similar to the calculation of a light tile.
N etc. = 0.9 * 12.06 / 0.0825 = 131.56, i.e. 132 pcs. We add 5%, as a result we get - 139 pcs.
Number of border material:
N b \u003d P / d 2, where
P - the perimeter of all walls minus the width of the doorway, in m
d 2 - width of the curb element, in m
Reminder! When choosing decorative elements, the number of required facing tiles decreases in direct proportion to the number of decor units.
We calculate the laying of tiles with a rhombus
The amount of material for this type of installation is calculated by analogy with the standard method, only its stock is not 5%, but 15%. The number of residues will be greater due to the cutting of the corners of the tiles at the junction with the walls.
How to calculate grout for joints
When calculating the required volume of grout, you need to know the amount of space to be filled. The standard seam width is 1.5-3 mm. A coefficient of 1.5 is applied to the joint depth parameter, which takes into account material shrinkage, moisture, etc.
To calculate the grout, the following formula is suitable:
V \u003d ((½ R pl / S pl) * T) * D * 1.5 * S total, where
V - the volume of material for the entire area of the tile, in kg
R pl - the perimeter of one tile, in m
S pl - area of one tile, m 2
T - thickness of the tile, in m
D - joint width, in m
S total - the total area of \u200b\u200bthe tile, in m 2
How to calculate the amount of adhesive for tiles
This is the simplest calculation of all of the above, because. on the container, the manufacturer indicates how much mixture is intended for 1m 2. To do this, it is better to first understand what layer the glue will be applied to.
There is nothing complicated in calculating bathroom tiles. There are old proven methods that have been tested by time and experts. It is important to avoid mistakes when measuring the parameters of the room and banal inattention.
