How Many Tiles Do I Need? Tile Calculator Guide for Floors & Walls

How Many Tiles Do I Need? Tile Calculator Guide for Floors & Walls To calculate tiles needed, divide your project area by the tile size, then add 10-15% for waste and cuts. For a 100 square foot bathroom floor using 12×12 inch tiles, you'd need approximately 100 tiles plus 10-15 extra, totaling 110-115 tiles. I tiled our 72 square foot master bathroom floor and three shower walls (about 96 square feet combined) using 12x24 porcelain tiles. I ordered 15% extra -- 97 tiles total -- and cracked 6 during cutting, which put me right at the edge. The project ran $1,250 in materials including thinset and grout, and that experience convinced me to always budget at least 15% waste for any tile job with wet-saw cuts.
