Frequently Asked Questions
How much extra tile should I buy for waste?
A 10% waste allowance is standard for simple layouts. Increase to 15-20% for diagonal layouts, complex patterns, or rooms with many cuts.
How do I measure an irregularly shaped room?
Break the room into rectangular sections, calculate the area of each separately, and add them together before entering the total here.
Should I buy extra tile for future repairs?
Yes, many homeowners buy one extra box beyond the calculated amount to have matching tiles on hand for future repairs, since dye lots can change.
