How Many Tiles Do I Need for a Shower? (2026 Guide)
How many tiles do I need for a shower? A standard 60×30 in tub surround with three 72 in walls is about 55–65 sq ft. Divide the measured wall area by one tile's sq ft, then add 10% for cuts.
Measure the three walls
Start from the walls you'll actually cover: for a tub/shower alcove that's the back wall plus two side walls; a tiled floor or ceiling adds area on top. The example below assumes a common 60×30 in tub with tile running 72 in up — always measure your own alcove first.
1. Back wall = length × height
The back wall of a 60 in tub is about 60 in long. At 72 in of tile height: 60 × 72 = 4,320 sq in ÷ 144 = 30 sq ft.
2. Side walls = depth × height
Each end wall is the alcove's depth — about 30 in for a standard tub: 30 × 72 = 2,160 sq in ÷ 144 = 15 sq ft per side.
3. Add the three walls together
30 (back) + 15 + 15 (sides) = 60 sq ft; real 60×30 surrounds usually land in the 55–65 sq ft range. Tiling above the tub? The three faces run 60 + 30 + 30 = 120 in (10 ft) around, so each extra 1 ft of height adds about 10 sq ft. Subtract anything you won't tile, like a window or niche.
Square feet per tile
Each tile size covers a fixed area: (width in × length in) ÷ 144 = sq ft per tile, and you divide your wall area by that for the piece count — the table below lists sizes, per-tile areas and counts.
Tile counts for a 60 sq ft shower area
For the 60 sq ft surround, buy about 10% over the raw area for cuts and breakage: 60 × 1.1 = 66 sq ft to cover. Divide 66 by the tile's sq ft and round up:
| Tile size | Area per tile | Tiles for 60 sq ft | Buy with +10% |
|---|---|---|---|
| 4 × 4 in | 0.111 | 540 | 595 |
| 6 × 6 in | 0.25 | 240 | 264 |
| 3 × 6 in | 0.125 | 480 | 528 |
| 4 × 12 in | 0.333 | 180 | 198 |
| 12 × 24 in | 2.0 | 30 | 33 |
Per-tile areas are rounded from exact values (a 4×4 tile is 1/9 sq ft, a 4×12 tile is 1/3 sq ft), so totals can shift by a tile or two. Counts are rounded up — confirm with your box's coverage or the tile calculator.
Worked example: two sizes on the same surround
Large format: 12×24 in tile covers 2.0 sq ft, so the walls need 60 ÷ 2 = 30 tiles; with 10% extra you cover 66 sq ft — 66 ÷ 2 = 33 tiles.
Small format: 6×6 in tile covers 0.25 sq ft (four per square foot): 60 × 4 = 240 tiles, and 66 × 4 = 264 tiles — eight times as many pieces.
Shower tiling tips that save time and tile
- Finish the waterproofing first — cement backer board with seams taped and sealed, and walls flat and plumb. Fixing a lipped wall after the tile is up costs far more than a few extra minutes.
- Count the cut-outs before you order — valve, spout, handheld hookup, electrical and any niche all need holes cut in the tile. Add a spare tile or two for the fiddly pieces.
- Order 10–15% overage from one dye lot — 10% covers cuts and breakage on a straight small-tile layout; use 15% for large-format, diagonal or herringbone patterns. A later reorder often won't match the dye lot.
Planning a whole room instead of one alcove? The same measure-then-divide math covers tiles for any room, and once the layout is set, how much grout do I need tells you how many pounds to mix.
FAQ
How many square feet is a 60×30 shower?
For a standard 60×30 in alcove at 72 in high, about 55–65 sq ft — the three walls model out at 60 sq ft (30 back + 15 per side). Tiling the floor, tub deck or higher walls adds more, so measure your walls.
Small tiles or large-format tiles: which is less work?
Large-format tile, generally. Fewer pieces means fewer grout lines: a 60 sq ft surround takes about 33 boards of 12×24 in tile versus 264 of 6×6 in tile — fewer joints to float and wipe.
Should I add extra tiles over my wall area?
Yes — add about 10% for cuts, corners and breakage, and plan 15% for large-format, diagonal or herringbone layouts. Returning unopened boxes beats reordering later and missing the dye lot.
