How it is worked out
Each area is length times width. The calculator adds your waste allowance for cuts and breakage and divides by the face of one tile. Adhesive is about 5.0 kg per m². Grout depends on the tile size and joint width.
How our tiling takeoff service works →Common questions
How much extra tile should I buy?
Add 10% for straight lay and 15% for diagonal or herringbone patterns, small rooms with lots of cuts and large-format tiles. Keep a few spare tiles from the same batch for repairs.
Can you measure tiling and waterproofing from my plans?
Yes. Send the PDF plans and Sigma Build measures every wet-area floor, wall and waterproofing zone from the drawings and prices the job at your rates.
