One of the most common questions we hear from homeowners is: how long will my bathroom renovation actually take? The short answer for a full bathroom remodel is about 5 weeks of active construction. But there is a lot that happens before and after those 5 weeks, and several factors can stretch or compress that timeline.
This guide walks through what happens each week, what you should expect, and how to prepare your home and your family for the process.
Before Construction Begins: Planning and Procurement
Before any tools come out, there is typically 3 to 6 weeks of planning. This includes your initial consultation, design meetings, material selections, and ordering. Tile, vanities, fixtures, and glass enclosures all have lead times. Imported tile can take 4 to 8 weeks to arrive. Custom vanities typically need 3 to 6 weeks.
If your project requires permits (and most bathroom renovations do if plumbing or electrical is involved), plan review adds another 2 to 4 weeks in most King County jurisdictions. Bellevue and Kirkland tend to process residential permits faster than unincorporated King County.
We always recommend having all materials on-site before demolition begins. Nothing stalls a project like waiting for a backordered shower valve or a tile that is stuck in a warehouse.
Week 1: Demolition and Rough-In
Day one starts with protection. We cover floors and walls in adjacent rooms with heavy plastic and rosin paper. Dust containment goes up. Then demolition begins.
A full bathroom demo typically takes 1 to 2 days. Everything comes out: old tile, drywall, vanity, toilet, tub or shower. We haul it all away in a dumpster. Once the room is stripped to studs and subfloor, we can see exactly what we are working with.
This is when we discover any hidden issues. Rotted subfloor around the toilet flange is common in older homes. Outdated plumbing (galvanized pipes) may need replacement. Water damage behind the shower walls might extend further than expected. We address these issues immediately, and this is why that 10% to 15% contingency budget matters.
After demo, the plumber comes in for rough plumbing. This means repositioning drain lines, supply lines, and shower valves to match the new layout. If you are keeping fixtures in the same locations, this step is minimal. If you are moving the shower to a different wall or adding a freestanding tub, it takes longer.
The electrician follows with rough electrical: new circuits for the exhaust fan, GFCI outlets, vanity lighting, and any heated floor systems. All rough work gets inspected before we close up the walls.
Week 2: Waterproofing and Substrate Preparation
This is the most underrated week of a bathroom renovation. What happens behind the tile determines whether your bathroom lasts 5 years or 25 years.
We install cement backer board on all walls that will receive tile. The shower area gets a full waterproofing membrane (we use Schluter Kerdi or a liquid-applied membrane like RedGard). The shower pan is built, sloped, and waterproofed. We do a flood test on every shower pan, filling it with water and leaving it for 24 hours to verify there are zero leaks.
If you are getting a curbless (zero-entry) shower, the subfloor needs to be modified to create the proper slope to the drain. This adds complexity and cost, but the result is worth it for accessibility and aesthetics.
New drywall goes up on non-wet walls. The cement backer board and drywall get taped, mudded, and sanded. Niches for shampoo storage are framed and waterproofed. By the end of week 2, the room is fully prepped and ready for tile.
Week 3: Tile Installation
Tile work is the most time-intensive part of the project. A skilled tile setter works methodically, and rushing this step shows in the finished product.
Shower walls go first, typically starting from the bottom and working up. Large-format tiles (12x24 or larger) require a perfectly flat substrate and more adhesive coverage. Smaller tiles like subway or mosaic are more forgiving but take longer to install because of the extra grout joints.
The shower floor gets tiled next, usually with a smaller mosaic tile (2x2 or hexagon) that can follow the slope to the drain. Then bathroom floor tile goes in. If you chose heated floors, the heating cable or mat was installed on the subfloor before the tile.
After all tile is set and the adhesive has cured (usually 24 hours), grouting happens. Grout color makes a bigger visual difference than most people expect. We always recommend a grout sample before committing. After grouting, grout sealer is applied to protect against staining.
The tile phase alone typically takes 5 to 7 working days. Complex patterns, mosaics, or large shower enclosures push toward the longer end.
Week 4: Fixtures, Vanity, and Glass
With the tile complete, the bathroom starts to look like a bathroom again. The vanity goes in first, including the countertop and sink. The plumber connects supply lines and drains. The mirror and vanity lighting get mounted.
The toilet gets set on a new wax ring and bolted down. Towel bars, toilet paper holders, and robe hooks go up. The shower valve trim, showerhead, and any body sprays get installed.
The glass shower enclosure is typically one of the last items installed. Frameless glass is measured after the tile is complete (not before) to ensure a perfect fit. The glass company usually needs 1 to 2 weeks of lead time after final measurements to fabricate the panels.
Painting happens during this week as well. We paint the ceiling first, then walls, then do any touch-up after fixtures are installed. Most bathrooms get a satin or semi-gloss finish for moisture resistance.
Week 5: Final Details, Cleanup, and Walkthrough
The last week is about the details that separate a good renovation from a great one. Caulking goes in at every transition: where tile meets the tub, where the vanity meets the wall, where the floor tile meets the baseboard.
Baseboard and trim get installed and painted. Any touch-up painting happens. Door hardware (if replaced) goes on. The exhaust fan gets its cover plate.
We do a thorough cleaning of the entire bathroom, including grout haze removal from tile, polishing fixtures, and cleaning glass. Then we schedule a final walkthrough with you. We go over every detail, test every fixture, and make a punch list of anything that needs adjustment.
The punch list items get addressed within a few days, and then the bathroom is officially done.
Factors That Extend Your Timeline
- Custom tile orders: Imported or specialty tile can take 4 to 8 weeks to arrive. Order early.
- Permit delays: Some jurisdictions take longer than others. Unincorporated King County can take 4 to 6 weeks for plan review.
- Hidden damage: Rotted subfloor, mold behind walls, or outdated plumbing can add 3 to 7 days.
- Material changes mid-project: Switching tile or fixtures after work has started creates delays. Make final selections before demo day.
- Weather (for exterior walls): If your bathroom has an exterior wall and the sheathing needs repair, heavy rain can pause work.
- Scope creep: Adding a heated floor, changing the shower layout, or upgrading to a freestanding tub mid-project requires re-planning and additional materials.
How to Prepare Your Home for a Bathroom Renovation
Remove everything from the bathroom: towels, toiletries, medications, cleaning supplies. Clear out any closets or cabinets that adjoin the bathroom.
If this is your only bathroom, plan ahead. Talk to us about phasing the project to maintain access to the toilet for as long as possible. A portable toilet is another option for longer projects. If you have a second bathroom, designate it as the household bathroom and stock it with everything you need.
Expect noise from 7:30 AM to 4:30 PM on weekdays. Demo day and tile cutting are the loudest. If you work from home, noise-canceling headphones are a worthwhile investment. Dust is inevitable, even with containment. Run your HVAC system on fan mode with a fresh filter to help capture airborne particles.
If you have pets, keep them away from the construction zone. Open doors, sharp tools, and construction debris are hazards.
Living Without a Bathroom: Practical Tips
- If you have a second bathroom, set up a shower caddy with all your daily essentials to keep things organized.
- A gym membership is a worthwhile short-term investment if you only have one bathroom. Most gyms offer 30-day trial memberships.
- Ask your contractor about phased scheduling. In some cases, the toilet can be reconnected temporarily during the evenings.
- Stock up on baby wipes and dry shampoo for the days when accessing a shower is inconvenient.
- If you have young kids, consider staying with family or friends for the first week (demo is the most disruptive phase).
Frequently Asked Questions
Yes, if the scope is limited. A tub-to-shower conversion with pre-fabricated wall panels (no tile) can be completed in 7 to 10 days. A vanity and flooring swap without plumbing changes takes 3 to 5 days. But a full renovation with custom tile, new plumbing, and frameless glass realistically takes 4 to 6 weeks.
Materials not being on-site when construction starts. Backordered tile, delayed vanity shipments, and custom glass fabrication are the top three. We strongly recommend having every item delivered and verified before demo day.
No. Most of our clients provide a lockbox code or smart lock access. We send daily progress updates with photos so you can see what happened each day. We do recommend being available by phone in case decisions come up.
In the Seattle area, a full bathroom renovation typically runs $25,000 to $50,000 depending on size, materials, and scope. A guest bath with simple finishes might be $20,000. A large master bath with heated floors, frameless glass, and custom tile can reach $60,000 to $75,000.
Doing multiple bathrooms at once is more cost-effective because you share mobilization costs, dumpster fees, and your contractor can batch similar work. But you need at least one functioning bathroom at all times. Many homeowners do the master and guest baths together while using a half-bath during construction.
