How Long Does a Bathroom Remodel Take?

Most of a bathroom remodel happens before anyone swings a hammer. Design, selections, ordering and the permit take up the front of the schedule, and the construction phase is shorter than many people expect but has to happen in a strict order. This page sets out that order, gives JDI Construction's own published on-site durations, and explains what tends to stretch a schedule. It does not assign weeks to phases that no reliable source publishes.

The phases in order

Before construction: design, selections and ordering

This is the part you control, and it decides whether the on-site weeks run smoothly. Every decision that is built into a wall has to be final before framing closes: the valve type and position, showerhead height, niche locations, blocking for grab bars and glass, lighting and outlets, and the fan. The vanity and tile should be ordered and, ideally, on site before demolition, so the crew is never waiting on a box. Lead times vary by product and season, and this guide does not publish them; ask what is being quoted today for the items you choose. The bathroom remodel checklist lists the decisions in order.

The permit

Not every bathroom needs a building permit, but remodels that touch plumbing, wiring or walls usually do. See do you need a permit. In the City of Vancouver, the application is emailed to the permit center, plan review fees are paid, and the plans go through prescreen and plan review before the permit is issued. The City's stated goal is to enter an application within one to two business days; it publishes no target for plan review and says the main factor is how well the submittal meets the requirements and the quality of the plans. The City of Vancouver permit process covers each step.

Demolition and rough-ins

Demolition is quick, but it is also when you learn what the room is hiding. Rot under the toilet, a failed shower pan or undersized framing has to be repaired before anything new goes in, which adds days nobody could schedule in advance. In homes built before 1978, painted surfaces may need lead-safe practices, and in a home of any age, suspect materials such as old flooring, mastics and wall textures have to be evaluated for asbestos before they are disturbed; see lead paint rules and asbestos in bathrooms. Then the trades rough in: drains and vents, supply lines and the valve, wiring and boxes, and the fan duct to the outside.

Inspections

Rough work has to be inspected before it is covered. In the City of Vancouver, inspections are requested through the Online Permit Center, by phone or by text, and can be scheduled up to five days ahead. The City's page says requests received after 7 a.m. are inspected the next business day, but do not build a schedule that depends on next-day service. The City's inspection codes for bathroom work include 410 Rough Plumbing, 725 Rough Wiring, 335 Exhaust/Ventilation Ducts and 140 Framing, with 495 Final Plumbing, 795 Final Electrical and 295 Final Building at the end. Outside the city, electrical inspections are L&I's, and L&I says inspection must be requested before covering any electrical work. A failed inspection means a correction and a second visit, so build a little slack around each one. See bathroom remodel inspections.

Waterproofing, testing and cure time

This is the phase that cannot be hurried. The shower floor is sloped, backing board goes on the walls, and the waterproof membrane or liner is installed. The Uniform Plumbing Code (408.7.5) requires a site-built shower receptor to be tested for watertightness by filling it with water to the level of the rough threshold. Membranes, mortar beds, thinset and grout each need time to cure before the next layer or before the shower is used, and the time depends on the product and the conditions; follow the manufacturer's instructions rather than a rule of thumb. Waterproofing explained describes the systems.

Tile, fixtures and glass

Tile takes time because it is detailed hand work: layout, cuts around the valve and niche, the floor slope, and grout. Once it is done the vanity and top go in, the toilet is set, trim and lights are installed, and the room is painted. Glass comes last. The federal safety glazing standard defines tempered glass as glass that cannot be cut, drilled or ground after tempering, so shower panels are measured from the finished tile and made to fit. Expect a gap between finished tile and installed glass, and ask your contractor what they are being quoted for fabrication.

What extends a schedule

• Hidden damage found at demolition, and the repair it needs.
• Selections made late, or a change after an item is ordered.
• A backordered item, especially a vanity, special tile or a valve.
• A failed inspection and the wait for the re-inspection.
• Layout changes that add a permit, structural work or a moved drain.
• Glass fabrication after tile is complete.

Getting a schedule you can rely on

Ask for a written schedule with the estimate, showing the order of work, the inspection points and when you will lose use of the room.
