How Many Tiles Do I Need for a Shower Wall?

Quick Answer

Measure each shower wall, add the wall areas, subtract large openings, then add 15% to 20% waste. Shower walls usually need more waste than open floors.

Use the [Tile Calculator](/tile-calculator) to adjust the dimensions, waste factor, product coverage, and unit price for your exact project.

Formula

``

Tiles needed = total wall area / tile area x waste factor

``

Example Estimate

1. Back wall: 5 x 8 = 40 square feet.

2. Two side walls: 3 x 8 x 2 = 48 square feet.

3. Total wall area is 88 square feet.

4. With 15% waste, plan for about 101 square feet.

Reference Table

| Layout | Suggested waste |

|---|---:|

| Simple straight layout | 15% |

| Niches or benches | 15% to 20% |

| Diagonal or complex pattern | 20% |

Practical Tips

- Buy tile from the same lot number.

- Mix tiles from multiple boxes.

- Order trim pieces separately from field tile.

When to Round Up

Round up when the project has cuts, corners, fragile materials, uneven surfaces, delivery minimums, or any chance that matching the same product later will be difficult.
