This civil engineering article provides detail information on working out the tiles quantities in the rooms or bathrooms of a building.

The first should be finding out the area of the room in which the tiles will be provided.

Let's assume, the shape of the room is L type and it is partitioned as part A and part B.

The dimensions of both are given as follow:-

Length of room A = 3 meter

Breadth of room A = 2 meter

Length of room B = 6 meter

Breadth of room B = 2 meter

Based on the above data, the area of A will be measured as follow:-

Area = Length x Breadth

After providing the values of length and breadth, we get the following result:-

Area = 3 x 2 = 6 square meter

Now, the area of B will be calculated as follow:-

Area = Length x Breadth

After providing the values of length and breadth, we get the following result:-

Area = 6 x 2 = 12 square meter

So, total area = area of A + area of B = 6 + 12 = 18 square meter

Assume the length of one tile as = 600 mm = 0.6 m and breadth = 600 mm = 0.6 m

Therefore, area of each tile = length x breadth = 0.6 x 0.6 = 0.36 square meter

So, the numbers of necessary tiles = Total Area / Area of One Tile = 18 / 0.36 = 50 Nos. (approx)

As wastage may occur in construction site, it should also be taken into the calculation.

The wastage may vary from one site to another and as per the sizes of the rooms.

Suppose, the standard wastage is 5%.

Therefore, 50 + 5% of 50 = 50 + (5/100 x 50) = 50 + 2.5 = 52.5 numbers = 53 numbers
