Labor Hours to Tile a Shower (2026): Large Format to Zellige, Niches to Curbless
One 3x5 shower worked in six tile formats, from 51 person-hours with 12x24 porcelain to 74 with zellige, plus what niches, benches, curbless floors, drains and slab walls add.
The assumptions
This model assumes
- A 3x5 alcove shower tiled to 8 feet: 88 sq ft of wall, 15 sq ft floor
- One niche, a built curb, a center drain and a 2x2 mosaic floor
- One experienced installer; person-hours, not crew days
- Tile and waterproofing only: demo, plumbing, electrical and glass are separate
- Estimates to check against your own logged hours
The model, step by step
A 3x5 alcove shower, tiled to 8 feet: 88 sq ft of wall and a 15 sq ft floor, one niche, a built curb and a center drain. These hours are the same whatever tile goes on.
| Task | Hours |
|---|---|
| Prep and backer | 4.6 |
| Waterproofing | 6.6 |
| Shower pan | 3.5 |
| Curb | 5.0 |
| Niche | 4.0 |
| Flood test | 1.5 |
| Edge trim, 16 lf | 1.0 |
| Total | 26.2 |
Setting is where the format shows up. These are typical rates for shower walls, setting only.
| Format | h per sq ft | Hours |
|---|---|---|
| 12x24 porcelain | 0.14 | 12.3 |
| 3x12 subway | 0.15 | 13.2 |
| 24x48 porcelain | 0.19 | 16.7 |
| 2x2 mosaic | 0.2 | 17.6 |
| 3x12 herringbone | 0.225 | 19.8 |
| 4x4 zellige | 0.28 | 24.6 |
Fewer pieces sounds quicker. On a shower wall, large format tile usually takes longer per square foot.
Why 24x48 runs slower
Flat wallsTile with an edge 15 inches or longer needs walls within 1/8 inch in 10 feet and 1/16 inch in 2 feet, so more prep
CoverageWet areas need 95% coverage, often by back-buttering
LippageLeveling clips and checks at every joint
OffsetNo more than a third on long tile, so layout matters
HandlingOften two people to lift and set
Where it saves time
GroutFar fewer joints to grout and clean
FloorWith a linear drain, one slope lets large tile run across the floor
Handmade zellige is uneven in thickness, size and face. That's the look, and it's the labor.
Where the time goes
SortingOpen and blend every box before you start
SettingBack-butter each piece; joints tight or edge to edge
SealingMany zellige lines are sealed before grout and again after, with cure time between. Follow your product's guide.
OverageOrder at least 15% extra for culls and breakage
The same tile laid in a pattern takes more cuts and more layout.
| Pattern | Multiply by |
|---|---|
| Offset, a third | 1.05 |
| Vertical stackEvery joint has to line up | 1.2 |
| Diagonal | 1.35 |
| Herringbone1.3 to 2.0 by cuts and walls | 1.5 |
| Chevron | 1.6 |
Fixed work, walls, a mosaic floor, grout, and 15% for setup, cleanup and material runs.
| Wall tile | Hours |
|---|---|
| 12x24 porcelain | 51 |
| 3x12 subway | 54 |
| 24x48 porcelain | 56 |
| 2x2 mosaic | 61 |
| 3x12 herringbone | 61 |
| 4x4 zellige | 74 |
Forum job accounts for a subway alcove like this suggest about 24 to 48 hours. The low end uses a foam tray and curb instead of building them. Angi puts shower tile at six to eight hours. That's one site day, not a shower.
The floor is 2x2 mosaic in every row. Grout scales with the joints: less for large format, more for mosaic and zellige. Zellige adds about 4 hours for its two sealing passes.
Calendar time runs about 8 to 12 working days for one installer, and about 10 to 16 with zellige. The membrane cures before the flood test, thinset cures before grout, and zellige waits again for each sealer coat.
Each of these changes the job more than the tile does.
| Feature | Adds |
|---|---|
| Second niche shelf | 2 h |
| Tiled bench, framedFoam benches go faster | 6.5 h |
| Curbless, wood floorCutting and reinforcing joists | about 16 h |
| Curbless, slabSaw-cut, trench and re-pour | 10 to 20+ h |
| Linear drainOne slope, large floor tile possible | similar |
| Tile-in drain grateCut tile to fit the insert | 1 h |
| Steam showerLow-perm membrane, sloped ceiling | a day or more |
Tile to the ceiling instead of 7 feet adds wall area at the same rate. Mitered outside corners take longer than metal trim. Glass is measured after tile, then often about a 2 week wait.
Gauged porcelain panels, quartz and natural stone slabs trade grout joints for crew size, shop work and material you can't use. On the same 3x5 shower, the walls take about 40 person-hours on site whatever the slab.
| Slab | Hours |
|---|---|
| Porcelain panelsCut on site; the maker must approve shower walls | about 40 |
| Quartz, 1 or 2 cmPlus the shop; some quartz warranties exclude shower walls | about 40 |
| Granite or quartzitePlus the shop; sealed; 2 cm runs 12 to 13 lb a sq ft | about 40 |
| MarblePlus the shop; etches, reseal every 6 to 12 months | about 40 |
What changes
CrewThree or four people to carry and set a panel
TemplatingMeasured after the walls are waterproofed, then cut in a shop or on site. Get the fabricator's scoped quote.
CutsThe valve, niche and outlets cut into the panel; one mistake costs a whole slab
CertificationGauged porcelain has its own installer standard and certification
Slabs to buyThree full-height pieces for 88 sq ft usually take three 5x10 slabs: buy about 1.5 times the wall area
WaterproofingStill a membrane behind the slabs; the slab isn't the waterproofing
The hours
On siteAbout 40 person-hours for 88 sq ft, a crew of three for about two days; 24 to 64 depending on panels and cuts
Before thatTemplating, then shop fabrication and cutouts for stone and quartz; porcelain is often cut on site

What it means
Your hours, line by line
Clamp shows person-hours on each labor line of an estimate, from its labor hours catalog. You can set your own hours on a labor line, like zellige walls. Log hours on site by role and see them against the estimate on the job's costs card. Pick slab walls on the bath tile, in porcelain, quartz or stone, and the estimate carries the panel hours, the shop fabrication and the cutouts.
On your next tile shower, log the hours by task: prep, waterproofing, setting, grout. Two or three jobs give you your own rates, and they'll beat any table here.
Questions
How long does it take to tile a shower?
For a 3x5 alcove tiled to 8 feet, about 51 person-hours with 12x24 porcelain, 54 with subway and 74 with zellige, prep to cleanup. Spread over about 8 to 12 working days for one installer, because membranes, thinset and grout each need time to cure. Estimates; setting rates by format are built from installer reports.
Is large format tile faster to install in a shower?
Not on walls. Tile with an edge 15 inches or longer needs a flatter wall, 95% coverage (often by back-buttering), lippage control and often two people to lift. Fewer pieces doesn't make up for it in a small shower.
Why does zellige take so long to install?
Every box gets sorted, every piece back-buttered, joints are tight, and unglazed zellige is sealed before and after grout, with waits between. Plan on roughly twice the setting time of subway tile and at least 15% extra tile.
How much longer does a curbless shower take?
On wood framing, recessing the joists is about a day for two workers, before the drain and the slope. On a slab it means saw-cutting and trenching, often more. A built curb is about 5 hours.
How long does a slab shower take to install?
About 40 person-hours on site for a 3x5 shower's walls, a crew of three for about two days, and 24 to 64 depending on panels and cuts. Templating and the shop's fabrication come first. Plan to buy about 1.5 times the wall area in slabs.
Can you use quartz or marble for shower walls?
Yes, with care. Cambria sells quartz slabs for shower walls, but Caesarstone's residential warranty excludes cladding, so check the maker. Marble etches and needs resealing. Either way, a waterproof membrane goes behind the slabs.
