Bathroom Tile Calculator

Separate floor and wall materials and deduct doors or windows from the surfaces they interrupt. Each material rounds into its own boxes.

By Alish Gautam, Software Developer · Updated · Calculation methodology

Start with the editable example below. Dimensions retain their physical size when units change. Region sets currency labels without converting currencies; confirm entered quotes after changing region.

Measured tiled surfaces

Use non-overlapping rectangles. Enter openings as area on the surface they interrupt.

Pattern records your choice; it does not silently change the allowance. Use a pattern drawing for offset or herringbone installation.

Project takeoff

Whole packages round up. Allowance is separate from purchased surplus. Prices omit labor, delivery, tax and other items unless explicitly entered.

Enter partial tile height directly. Tub surrounds are extra surfaces. Trim length is entered from measured exposed edges, not inferred from room perimeter.

How it works

Surface areas group by product. Tile and box rounding occurs after grouping identical materials, never across different products.

Assumptions and limitations

Enter partial tile height directly. Tub surrounds are extra surfaces. Trim length is entered from measured exposed edges, not inferred from room perimeter.

Whole packages round upward after the chosen allowance. Physical geometry and purchase reserve are separate. Manufacturer and project specifications override editable examples; the selected region does not establish a local code requirement.
