Waste and material costs
How waste and pack/coverage pricing turn measurements into tiling order quantities.
Two settings on every component decide how a raw measurement becomes the number you actually order: waste and material price/pack sizing. For tiling, pack sizing also covers bagged materials priced by coverage rate.
Waste
Tile waste matters more than most trades because the cuts are unforgiving and the supplier batch can vary.
- Floor tile (standard format): 10–15% percentage
- Floor tile (large format, 60×60 and up): 15% percentage
- Wall tile: 10–15% percentage
- Mosaic or small-format tile: 15–20% percentage
- Diagonal or herringbone lays: add 5% to the standard
- Trim and edge profiles: 10% percentage covers cuts and mitres
- Adhesive and grout: handled by coverage rate, not waste — set the coverage on the component
Material price and pack sizing
Three strategies for tiling:
Per unit. Trim profiles per metre, fittings per item.
Per pack (tile). Tile comes in boxes with a known m² coverage. Set the pack size and unit price, and QuoteCore+ rounds the order up to whole boxes.
Per pack with coverage (adhesive, grout). Adhesive comes in 20 kg bags that cover ~5 m². Grout comes in bags with a coverage rate that depends on tile size and joint width. Set the bag size, coverage per bag, and unit price — QuoteCore+ works out how many bags from the tiled area.
Pitch multiplier
Not applicable for tiling work. Floors and walls are measured flat — there's no slope adjustment to apply. Leave it off.
A worked example
8 m² shower wall, 30×60 porcelain tile supply and fit. Plan area: 8 m². Waste at 12%: 8.96 m² to order. Pack size 1.2 m² per box: round up to 8 boxes (9.6 m²). Adhesive at 5 m² per bag: 2 bags. Grout at 6 m² per bag: 2 bags. That's what the customer is charged for material on the quote, and what your supplier sees on the order list.
