FAQ
How much waste should I add for tiles?
10% covers standard cuts and breakage for rectangular rooms; use 15% for diagonal layouts or rooms with many obstacles.
Does tile size affect the number needed?
Yes — smaller tiles mean more cuts at edges, so slightly more waste, while large-format tiles cover faster but break more in transit.
Should I buy extra boxes?
Buy full boxes even if the count says fewer tiles; dye-lots vary, so matching a discontinued shade later is nearly impossible.
