### How to calculate wall tiles?/ Calculating the number of wall tiles required for a bathroom.

Let us now calculate the area and number of wall tiles required for the bathroom as shown below.

Given data:

Length of the bathroom = 9ft.

Width of the bathroom = 7 ft.

Bathroom height = 9 ft.

Door size =2.5ft × 6.5 ft

Window size = 1.5ft × 3ft.

Let us select a tile of size 10" × 16", and let us fix the tile up to the full height of the bathroom.

Now, the number of wall tiles required

= Area of bathroom wall ÷ area of one tile.

First, we will calculate the area of the bathroom wall that should be tiled & the area of a single tile.

Bathroom wall area

= [{(2nos.× wall-length )+ (2nos × wall width)} × wall height ]- [( door area ) + ( window area )]

= [ {( 2nos. × 9ft. ) + ( 2nos. × 7ft.) }× 9ft.] - [(2.5ft × 6.5ft.) + ( 1.5ft × 3ft )]

= [ { ( 18ft. + 14ft. } × 9ft.] - [ ( 16.25sqft. + 4.5sqft.]

= [ 32ft. × 9ft.] - [ 20.75 sqft.]

= 288 sqft. - 20.75 sqft.

= 267.25 sqft.

Area of a tile

= 10" × 16"

= 0.833ft × 1.333ft

( Dividing by 12, we have converted inches into ft. )

= 1.111 sqft.

The number of wall tiles required

= Area of bathroom wall ÷ area of one tile

= 267.25 sqft.÷ 1.111sqft.

=240.55 nos.

Taking 10% extra for wastage & future use

= [240.55 nos. + (240.55 × 10) ÷ 100]

= [240.55nos. + 24.55 nos.]

= 265 nos.
