Wall Tile Calculator (Bathroom & Kitchen)
Wall tiles and boxes for showers, backsplashes and full-height bathroom walls.
Wall tile is sold by the box and dye-lot matched — buy 100% upfront plus spares. Wet areas need tile over a waterproofing membrane, not directly on bare drywall.
Formula
Wall Tile Calculator (Bathroom & Kitchen) is a free wall tile calculator for civil engineers, contractors and quantity surveyors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Wall Tile Calculator (Bathroom & Kitchen)

Frequently asked questions
What formula does the Wall Tile Calculator (Bathroom & Kitchen) use?+
It computes tiles = ⌈area × (1+waste) ÷ tile area⌉, per TCNA Handbook wall-tile methods. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Wall tile is sold by the box and dye-lot matched — buy 100% upfront plus spares. Wet areas need tile over a waterproofing membrane, not directly on bare drywall.
Does it include wastage?+
Yes — standard wastage/bulking factors are built in and stated in the formula line, so the quantity is an orderable number, not a bare geometric volume.
Is the Wall Tile Calculator (Bathroom & Kitchen) free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
