Large tile creates fewer grout joints and a continuous appearance but places greater demands on substrate preparation. Walls and floors that appear smooth may still need flattening. The installer should use appropriate mortar, trowel, back-buttering, leveling techniques, and movement joints. Quantity should include breakage, cuts, pattern layout, and future repair pieces.

Key considerations

  • surface flatness
  • bond strength
  • appearance retention
  • fewer grout joints
  • large sizes
  • continuous design
