Shower Tile Calculator — Wall & Pan Estimator
Calculate the exact square footage of tile required for standard 3-wall shower enclosures. Output includes net area and recommended material orders with waste margins.
For custom showers, professional tile setters recommend a 15% to 20% waste factor. The high number of corners, niches, plumbing fixtures, and drain cuts inside a shower enclosure leads to far more broken or unusable off-cuts than a standard floor installation.

Using a Shower Tile Calculator
A reliable shower tile calculator is critical because bathrooms are tight spaces requiring precise cuts around plumbing.
- Shower Wall Tile Calculator: When calculating wall tile, remember to measure the total height you intend to tile up to. Standard builder-grade showers stop at 72 inches (6 feet), but premium custom showers often tile all the way to the 8-foot ceiling or even across the ceiling itself!
- Diagonal Patterns: If you plan to lay your shower pan tile or wall tile on a 45-degree diagonal pattern, you must increase your waste factor to at least 20%. Diagonal layouts require cutting almost every single perimeter tile, significantly reducing the usable square footage of your material.
