Waterproofing and layout come before tile counts

Shower tile formula

Floor area = shower length × shower width

Wall area = tiled wall length × wall height

Net area = floor area + wall area - openings

Boxes = net area × (1 + waste %) ÷ box coverage

Sample takeoff

A 3 ft by 5 ft shower with 11 ft of tiled wall length, 7 ft wall height, 10 ft² of openings, 12×24 in tile, 10 ft² boxes, and 10% waste needs about 10 boxes and 46 tiles.A 0.9 m by 1.5 m shower with 3.3 m of tiled wall length, 2.1 m wall height, 0.9 m² of openings, 300×600 mm tile, 0.93 m² boxes, and 10% waste needs about 9 boxes and 46 tiles.
