How many tiles 18X18 to tile a 42 square ft bathroom?

Answer 1

To determine how many 18x18 inch tiles are needed for a 42 square foot bathroom, first convert the tile size to square feet. An 18x18 inch tile is 1.5 feet by 1.5 feet, which equals 2.25 square feet per tile. Then, divide the total bathroom area (42 square feet) by the area of one tile (2.25 square feet): 42 ÷ 2.25 = 18.67. Since you can't use a fraction of a tile, you would need 19 tiles to cover the bathroom.
