How much tile waste should I add?

Use 10% for simple layouts and 15-20% for diagonal patterns, niches, or many cuts.

Does grout count in tile area?

No. Tile count is based on surface area; grout and setting materials are estimated separately.

Measure each wall rectangle and subtract large openings, then add waste for cuts and niches.

Tips & notes

Assumptions that most often change the final quantity in the field—so you order with clearer eyes.

Use at least 10% waste for most tile and 15% for diagonal layouts or fragile tile.

Confirm whether trim pieces, bullnose, or Schluter profiles are separate.

Order from the same lot number for consistent shade and caliber.

Keep spare tile for future repairs.
