You are planning to have your bathroom floor tiled with 8 inch by 8 inch tiles, that cost $17.54 per box of 12 tiles. The tiled area is approximately 8 feet by 10 feet and the tiler charges a base fee of $100 and $12 per square foot. The grout and other materials are estimated at $10 per square foot. About how much will the project cost? Add 10% to the number of tiles for partial tiles needed.
