Why waste matters

Cuts at walls, breakage, and pattern matching consume tiles: 10% waste suits straight layouts, 15% for diagonal or herringbone, and more in rooms with many corners. Buy it all from one dye lot — later boxes rarely match exactly.

Boxes are the real unit

Stores sell boxes, not tiles, so the box count rounds up and the true surplus is often 15–20%. Keep a few spares after the job: a matching replacement tile turns a cracked-tile disaster into a 20-minute fix.
