A bathroom refresh that leaves the tub and supply lines alone is a few working days. A full remodel in the same layout adds up to about 100 hours of labour in the market figures we work from, and those hours usually spread over weeks. Inspections, drying time and parts on order make the gaps. Get a pro to look before anything is torn out.
I'm Slava, and this is how the time breaks down on the bathroom remodels we take on, stage by stage, and what to settle before demo.
How long does a bathroom remodel take, by size of job?
Here are the labour hours in the market data, and what they mean on the calendar. Labour hours are person-hours of work, not days on site; the next section shows why.
| Job | Labour hours (market data) | Calendar time |
|---|---|---|
| Refresh: fresh paint and caulk, a new vanity, mirror and accessories; tub and plumbing stay | about 24 | |
| Tub-to-shower conversion | about 30 | |
| Full remodel, same layout: walls and floor retiled, new vanity, tub or shower replaced | about 100 | |
| Layout change: toilet or drain moved | no market row |
A full remodel near Portland costs $7,700 to $35,000 with materials, by the November 2026 market data . The bathroom remodel cost guide explains where in that spread a job lands.
Plenty of Cedar Hills tract homes from the 1950s and 60s still have their first bathroom, and most of Cedar Mill went up in the 60s and 70s. A first remodel in a room that old is usually the 100-hour job.
Why does a 100-hour job take weeks?
One person on 40-hour weeks needs two and a half of them to put in 100 hours. A second pair of hands shortens the hands-on part, but it can't shorten a wait.
The waits are what fill the calendar:
- Inspections. Where a permit applies, the work gets looked at after rough-in, and nothing covers the pipes until it passes.
- The plumber and the electrician. Each visit goes on their calendar, so it's a booked day with a gap on either side.
- Curing and drying. Thinset, grout, drywall mud and paint each need their time before the next layer.
- Parts. A vanity, a valve body or a glass panel that shows up late holds the finish work.
In a cold, damp west-side house in late winter, mud and paint can dry slower than the label says.
What happens day by day in a full bathroom remodel?
This is the order on a same-layout job. The hours shown are market data; the blanks are mine to fill in from real jobs.
| # | Stage | What happens | Hands-on time | Before the next stage |
|---|---|---|---|---|
| 1 | Protect and tear out | floor and hallway covered, dust wall up, fixtures out, old tile and wallboard off | see what's under the floor and behind the walls | |
| 2 | Fix what demo found | subfloor and framing repairs | about 10 labour hours for a subfloor repair | the floor is solid before anything goes on it |
| 3 | Trade rough-in | plumbing and wiring replaced or moved | separate trade visits | inspection, where a permit applies |
| 4 | Close the walls, waterproof the shower | backer board, drywall, membrane, shower pan | membrane cured, pan water-tested | |
| 5 | Tile | floor and wall tile set, then grouted | about 20 labour hours for floor tile | grout cured before sealing and heavy use |
| 6 | Paint | walls, ceiling, trim | about 7 labour hours for one room | dry before fixtures go back |
| 7 | Fixtures and trim-out | vanity, toilet, trim pieces, shower door, accessories | shower door about 4 h; accessories about 2 h | final trade hookups, final inspection where a permit applies |
| 8 | Punch list | caulk, touch-ups, walk-through with you | none |
The first two stages are loud and dusty, and they decide the schedule. With the floor open, I can see whether the plywood by the toilet is sound or soft. Soft gets fixed right then, because tile over a spongy floor cracks.
The water test on the pan is the step that's easiest to skip and the most expensive one to have skipped. A leak found now costs an afternoon. Found after tile, it costs the tile.
Tile, paint and fixtures run in that order for a reason. Paint follows tile so grout haze never lands on finished walls, and the vanity goes in last so it isn't sitting in the dust.
What has to happen before demolition day in an Oregon house?
A few Oregon steps take real calendar time before day one, and none of them can be squeezed in halfway through.
A written contract. Any home job priced above $2,000 needs one, with three required notices attached. If a smaller job climbs over that line after it starts, the contract must be put in writing within five days.
An asbestos survey if the house predates 2004. DEQ requires an accredited inspector to survey the house before any renovation starts. Crumbly, friable material can only come out with a abatement contractor, and pulling nonfriable material such as old vinyl floor tile means notifying DEQ five or more days ahead. Nearly every house in our area was built before 2004, so plan for this. We don't remove asbestos (see the full list).
Lead paint if the house predates 1978. Oregon treats a pre-1978 house as having lead paint until testing says it doesn't, and work that disturbs over 6 sq ft of paint per room is renovation under the rules.
Permits. Relocating plumbing, or altering pipes hidden in walls or below the floor, needs a plumbing permit, and often trade permits are all a bathroom needs. The issuing office depends on the address: Portland, Beaverton, or Washington County for unincorporated areas such as Cedar Mill and Bethany. Details are in the permit guide.
What delays a bathroom remodel once the walls are open?
The usual surprise in houses over a crawl space is rot. A toilet seal that seeped for years softens the subfloor around the flange, and a failed caulk line does the same along the tub. Replacing a section of subfloor runs about 10 labour hours in the market data, roughly a day, before anything new goes down.
Changes after the walls close send a stage backwards. Moving a niche or switching tile once the board is up means redoing finished work.
Missing parts stall the end of the job. My rule is that nothing gets torn out until the vanity, the valve and the tile are in the house or have a firm delivery date.
Rain doesn't slow it down; it's an indoor job.
Can you use the bathroom during a remodel?
Not the room itself, from tear-out until the last bead of caulk. Whether the toilet can go back on overnight on some days depends on the stage.
If it's your only shower, sort that out before we start. A gym with showers, family nearby, or a few nights away during the wettest stages all work. Tear-out days are the noisy ones.
How long do smaller bathroom jobs take?
The market data puts these at:
- a bathroom refresh: about 24 labour hours;
- a tub-to-shower conversion: about 30 labour hours;
- regrouting: about 6 labour hours;
- new floor tile: about 20 labour hours;
- a shower door: about 4 labour hours.
A one-day bathroom? A fixture swap or an acrylic liner, maybe. A tiled one can't be, because thinset sets before grout goes in, and grout needs its cure before anyone showers.
What keeps a bathroom remodel on schedule?
Pick everything that goes inside a wall before demo: the valve, where the niche sits, the tile layout. Have the tile, the vanity and the valve in the house before the first day. In a pre-2004 house, book the asbestos survey early, and keep one person on your side who answers our questions the same day.
