Extra tiles for cuts, breakages, and future repairs. 10% suits a simple layout; 15-20% for diagonal patterns or busy rooms.

Buy 144 tiles to cover the area with a 10% allowance.

  • That is 131 tiles to cover the bare area plus 13 extra for cuts and breakages.
  • Order tiles in a single batch so the colour and shade lot match across the whole floor.
  • Turn on the cost estimate to see how many boxes to buy and the total tile cost.

Next stepKeep a few spare tiles after the job for repairs, since matching a discontinued range later is hard.
