The Shower Tile Calculator tells you how many tiles you need for a shower or bathroom enclosure, based on wall length, height, and tile size. Simply fill in the fields above and click Calculate to get an instant result.
This calculator is part of Calculate Wiki’s Construction Calculators collection.
What You’ll Need
- Shower Wall Length (combined) — sum of all wall widths
- Shower Wall Height
- Tile Width and Tile Height
- Waste Allowance — showers typically need extra for cuts around fixtures
Formula Used
Shower wall area = Combined Length × Height
Tiles needed = (Wall area × (1 + Waste%)) ÷ Tile area
Example Calculation
Using example inputs — Combined Length = 10 ft; Height = 7 ft; Tile = 12 in × 12 in; Waste = 12% — the Shower Tile Calculator returns:
| Value | Result |
|---|---|
| Shower wall area | 70 sq ft |
| Total area (with waste) | 78.4 sq ft |
| Tiles needed | 79 |
79 tiles needed.
