How Long Does a Custom
Shower Take to Tile?
A realistic day-by-day breakdown — including the waiting periods that can't be compressed, and why a three-day quote is a warning sign.
Most custom tile showers take five to nine working days of active work, which usually lands somewhere between a week and a half and two and a half weeks on the calendar once you account for cure times and material deliveries.
That number surprises people. It surprises them more when they get a quote promising three days. So here's where the time actually goes.
Day by day
Demolition
Old tile, substrate, and pan come out down to the studs. We check the framing while it's open — rot, out-of-plumb walls, and undersized blocking all have to be addressed before anything goes back. This is also where surprises surface on older Portland homes.
Framing corrections & substrate
Walls get shimmed or re-framed where needed, blocking goes in for benches and grab bars, and the substrate or waterproof panels go up. Tile is unforgiving of a wall that isn't flat — especially large format — so this day pays for itself.
Pan build & waterproofing
The shower pan is formed with correct slope to the drain, the membrane goes on, and every corner, seam, and penetration gets sealed. This is the day that determines whether the shower lasts.
Flood test — 24 hours
The drain is plugged, the pan is filled, and it sits overnight. Next morning we check the level and inspect below. No active work happens, but this is non-negotiable: it's the only chance to confirm the waterproofing holds before it's sealed under tile forever.
Tile setting
Layout first — we dry-lay to center the pattern, land cuts where they're least visible, and make sure nothing awkward happens at the niche or the ceiling. Then setting. One day for a straightforward subway layout, two or more for mosaics, herringbone, large format, or anything with a feature wall.
Thinset cure — 24 hours
Grouting over thinset that hasn't cured traps moisture under the tile and can cause discoloration and weak bonds. Another waiting day with no visible progress.
Grout
Grout goes in, haze gets cleaned off, and flexible sealant goes into every change of plane — corners, the wall-to-pan joint, and the perimeter. Those joints are deliberately not grouted so the assembly can move without cracking.
Seal, fixtures & walkthrough
Cement grout gets sealed once it's cured, trim and fixtures go on, and we walk the whole thing with you before calling it done.
The flood test and the thinset cure are roughly 48 hours combined where nothing visibly happens. They're the two easiest days to delete from a schedule, and they're the two that most directly determine whether the shower is still sound in ten years.
Grout also needs to cure before the shower gets used — typically another two to three days after the job wraps, depending on the product.
What pushes the timeline longer
- Small or intricate tile. A penny round or hex floor has enormous numbers of cuts around the drain. Mosaic sheets look fast and aren't.
- Patterns. Herringbone, chevron, and basketweave all mean more cuts, more layout planning, and more waste.
- Large format tile. Fewer tiles, but far less forgiving. Walls must be dead flat, and every cut is heavy and slow.
- Niches, benches, and curbless entries. Each adds waterproofing complexity and detail work. A curbless shower in particular requires floor framing modification and adds real time.
- Natural stone. Marble and travertine need sealing before grout, sometimes before install, and they're less tolerant of error.
- Old houses. Portland has a lot of homes from the 1920s–40s. Opening a wall frequently reveals framing that's out of plumb, prior water damage, or plumbing that needs to move.
- Other trades. If plumbing or electrical has to be relocated, that's a separate crew and a separate schedule.
Why three-day quotes are a red flag
Three days is physically achievable, but only by removing specific things:
- No flood test
- Grouting over uncured thinset
- Spot-bonding tile instead of achieving full coverage
- Skipping the pre-slope, or using a shortcut pan assembly
- Grouting the corners solid instead of using flexible joints
Every one of those saves hours and costs years. The shower will look identical on handover day. The difference shows up somewhere between year three and year seven, and by then the fix is a full tear-out.
If a timeline seems fast, the useful question isn't "can you do it faster" — it's "walk me through how you're handling the pan and the flood test." The answer tells you most of what you need to know.
If it's your only bathroom, plan for roughly two weeks without that shower, and ask your contractor to confirm the material lead time before demo starts. Tile that's backordered after the wall is open is the most common cause of a stalled project.
What you should get in writing
A quote worth trusting includes the waterproofing system by name, confirmation that a flood test is included, a realistic day count, and what happens if something unexpected turns up behind the wall. We put all of that in every written quote before any work starts.
