Tiling calculators
A tiling order is decided by the format rather than by the area. The same bathroom takes a different number of boxes, a different bed of adhesive and a different weight of grout depending on the size of the tile — and the cutting waste rises with it, because a large-format offcut fits nowhere else.

How tiling is measured
Square metres converted to boxes, kilograms of adhesive at a bed depth set by the trowel and the tile's flatness, and kilograms of grout from the joint width, the joint depth and the tile's perimeter-to-area ratio. Every one of those depends on the format.

What gets left off a tiling order
- The bed depth. A large tile needs a deeper notch and often a back-butter, which can double the adhesive against a small-format figure.
- Cuts at every perimeter, and the fact that a cut tile's offcut usually cannot be used on the opposite wall.
- The substrate: backer board, primer, decoupling or tanking under the tiles, each an area of its own.
- Trims, profiles and the silicone at every change of plane, which are linear and are always ordered late.
