Let us now calculate the area and number of wall tiles required for the bathroom as shown below.
Given data:
Length of the bathroom = 9 ft.
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.
Calculation:
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.
