Tip:
Tile calculators provide an area-based estimate.
Actual installation requirements can be higher because
of cuts, layout, grout joints, irregular walls or floors,
diagonal patterns, and damaged tiles. For complex layouts,
buying a little extra material is usually safer than
buying exactly the calculated amount.
