How Long a Bathroom Remodel Takes, Week by Week

The short answer

Job	Time on site	Before we start
Hall bath refresh (nothing moves)	About 2 weeks	2–4 weeks for selections and ordering; often no permit
Full hall bath (layout, valve or drain moves)	2–3 weeks	Selections, ordering and the permit, run together
Primary bathroom	4–6 weeks	Design meeting, custom orders and the permit
Tub-to-shower, acrylic	About 1 day	Measuring and ordering the panels
Tub-to-shower, tile	About 5 days	Selections, ordering, and a permit if the drain or valve moves

Times on site are working days after materials arrive. The weeks before are mostly waiting for orders and for the permit, and both of those run in parallel.

Before demolition

Site visit and estimate. We measure the room, look under the house or at the slab, and check the panel and water heater. The written, itemized estimate follows within 48 hours.

Selections. Tile, vanity, top, fixtures and glass. Stock items arrive in days. Custom vanities and special-order tile can take several weeks to arrive, which is the most common reason a start date moves out.

Permit. If plumbing moves, a circuit is added or a wall is opened, we draw the plans and apply. Review times depend on the city. Palo Alto, for example, runs an express track for simple work, and some cities review in a few weeks while others take longer. We apply as soon as the design is final.

Ordering. We order everything before we open the room, and we check every box when it arrives. That is how the bathroom stays out of service only while we are working in it.

A full hall bath, week by week

Days 1–2: protection and demolition. Floor protection from the front door, a sealed dust wall at the bathroom, and demolition to the studs at the wet walls. This is when hidden damage shows up: rotted subfloor at the toilet, a leaking drain, old wiring. Anything we find is priced in writing before we fix it.

Days 3–5: framing, plumbing and electrical. Repairs to subfloor and studs, blocking for grab bars, glass and the vanity, and framing for niches. New valve, drain and supply lines, pressure-tested. GFCI circuits, the exhaust fan and lighting.

Rough inspections. The inspector checks the plumbing and electrical before walls close. Scheduling depends on the city, usually within a day or two.

Days 6–8: walls and waterproofing. Cement or foam board in the shower, drywall elsewhere, and a bonded waterproofing membrane over the shower walls and pan. The pan is flood-tested for 24 hours. Many cities also inspect the shower pan.

Days 9–12: tile. Floor and wall tile, niches and trim, then grout. Tile is the longest single stage, and large-format or patterned tile takes longer than standard sizes.

Days 13–15: fixtures and finish. Vanity and top, toilet, faucets, accessories, paint and caulk. Glass is measured after tile and installed about a week later, so a curtain rod goes up in the meantime.

Final. Final inspection, a walk-through with you and a punch list, and the written warranty.

A primary bathroom

A primary bath follows the same sequence with more of each step: a larger shower, a double vanity, often a freestanding tub, sometimes a wall moved into a closet. Four to six weeks on site is typical. Heated floors add a day before tile, and a new circuit for them adds to the electrical rough-in.

What makes it take longer

• Hidden damage. Rot, failed drains or old wiring behind the walls. Usually a day or two once it is priced and approved.
• Slab work. Moving a drain in a slab home means saw-cutting and pouring concrete back, which adds a few days. In an Eichler, the slab is scanned first.
• Changes after tile starts. A moved niche or a different tile once the walls are set is the most expensive kind of delay.
• Late or wrong orders. This is why we order before demolition and inspect every delivery.
• Inspection scheduling. It varies by city and season. We book inspections as soon as each stage is ready.
