Shower Tile Calculator

Record walls, floor, niche returns, bench faces and curb faces as separate labeled surfaces. Assign wall, floor or accent products and round each independently.

By Alish Gautam, Software Developer · Updated 4 October 2026 · 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. Add each niche back and return, bench face, curb face or ceiling separately. Deduct the niche opening from its wall.

Project takeoff

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

Gross measured area: 72 ft²
Opening / exclusion deductions: 0 ft²
floor: net area: 9 ft²
floor: tiles with allowance: 10
wall: net area: 63 ft²
wall: tiles with allowance: 278

Supplier-ready material list

floor tile boxes: 1
wall tile boxes: 14
Measured exposed trim: 0 ft

Geometry / layout breakdown

Dimensions use the selected measurement system.
Surface	Material	Gross (ft²)	Net (ft²)
Floor	floor	9	9
Back wall	wall	21	21
Left wall	wall	21	21
Right wall	wall	21	21

Deduct the niche opening from its wall before adding niche back and returns. This is a tile takeoff, not a waterproofing, slope or drainage design.

How it works

Each physical tiled face contributes length × width − openings. Material groups receive separate tile dimensions and box counts.

Assumptions and limitations

Deduct the niche opening from its wall before adding niche back and returns. This is a tile takeoff, not a waterproofing, slope or drainage design.

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.
