Tile Installation Cost Calculator — FAQs
How much waste should I allow?
10% for straight laying in square rooms, 15% for diagonal/herringbone, 20% for rooms with lots of cuts around fixtures. Keep spares — batch shades vary.
Grout and adhesive?
Roughly 0.5kg grout and 3–4kg adhesive per m² depending on tile size — check the bag coverage, big-format tiles need more.
