Tile & Waterproofing Buying Room. Buy with a clearer brief.
A tile selection becomes a complete purchase only when the substrate, waterproofing, setting materials and finish details are coordinated. Separate the decorative surface from the underlying system in every quote.
Tile dimensions, finish and application suitability
01 / A working quantity
Build your purchasing worksheet.
Use measured quantities and actual supplier package sizes. The example inputs show the arithmetic; they are not a project takeoff or an ordering recommendation.
Quantity calculator
Measured quantity × (1 + allowance ÷ 100) ÷ package coverage, rounded up. Counted items use one item per order unit. Confirm cuts, overlaps, accessories and ordering increments with the supplier.

- Are testing, edge trims and specialty cuts included?
04 / Delivery day
Check the order before it disappears into the build.
