The math (12×24 tile)
250 sq ft × 1.10 = 275 sq ft
275 × 144 ÷ (12 × 24) = 138 tiles (rounded up)
Setting materials
Thinset coverage depends on the trowel notch: larger tiles need a bigger notch and more mortar. Check the coverage chart on the bag for your trowel size, and buy grout by the coverage chart for your tile size and joint width.
