Questions
Tile Calculator FAQ
How much tile waste should I allow?
Straight layouts often use about 10 percent; diagonal patterns, small rooms, and complex cuts can require more.
Why does grout spacing affect tile count?
Each installed module includes the tile plus a joint, so spacing changes the number that fits across a surface.
