Levelling, priming and boarding should be priced separately from the tiling.

Planning estimates only. Adhesive figures are typical manufacturer consumption rates (e.g. Mapei Adesilex P9); grout uses the standard formula (L+W)/(L×W) × joint width × tile thickness × 1.6, plus 10%. Always check the data sheet for the product you are using.

HOW THE NUMBERS WORK
Working out a floor
Multiply the length by the width of the room, add any bays or alcoves, and take off anything that won't be tiled, like fitted kitchen units or a bath. Add wastage for the layout: about 10% for a straight lay, 15% for diagonal and 20–25% for herringbone. Floors usually need more adhesive than walls. Mapei's data sheet puts large-format tiles and floors that need a solid bed at about 5 kg/m², so that's the starting value here.

What to measure, what to allow for, and how to price it.
Read the guide →Herringbone and large format
Both use more tile and take longer to lay. Price them accordingly.
