Large tile reduces grout joints but requires a flatter supporting surface. The installer may need patching, self-leveling, or wall flattening before installation. Large-format mortar, back-buttering, appropriate troweling, and lippage-control methods may be necessary.

Key considerations

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