Frequently Asked Questions
How much extra tile should I buy?
A 10% waste factor is standard for simple straight installations. Add 15% for diagonal layouts or rooms with lots of cuts. Always buy an extra 5–10% beyond what you calculate to have spare tiles for future repairs. Dye lots can vary between production batches, making it difficult to match tiles purchased later.
How many tiles come in a box?
Tile boxes typically contain 10–20 tiles and cover 10–20 square feet, depending on tile size. Check the box for exact coverage. When purchasing, round up to full boxes and keep the extras — matching tiles for future repairs can be difficult if the line is discontinued.
