What changes a tile order most
Tile size, layout pattern, breakage risk, and whether the job needs separate adhesive and grout calculations are usually the biggest drivers of the final order.
When to increase waste
Increase the waste allowance for diagonal layouts, feature borders, awkward cuts, or jobs where future matching tiles may be difficult.
Before you order
Check tile box coverage, adhesive coverage, grout yield, and whether trims, movement joints, and backer boards need to be bought separately.

Use this project hub to brief suppliers or installers
Work through the core calculator first, then use the linked guides and quote checklist to request cleaner, more comparable prices.
- Confirm what the quote should include: materials only, labour only, or both.
- State access, finish level, timing, and any unknowns clearly.
- Ask each supplier or installer to price the same scope and exclusions.
You can also open the wider Tile Estimating project hub if the quote depends on more than one material.
