What Order Should You Renovate a Bathroom In?
Renovate a bathroom in this order: design and plan, demolition, rough-in plumbing and electrical, inspection, then walls and waterproofing, install tub or shower, tile, paint, and finally vanity, fixtures, and finishing. Working in this sequence prevents redoing work, like flooring damaged by later trades, which is the most common ordering mistake.
A bathroom remodel is essentially a sequence puzzle, and getting the order wrong is what turns a clean project into a redo. Tile before waterproofing, flooring before the messy trades, fixtures before paint, each is a classic, avoidable mistake. Here is the order professionals actually follow, and why each step lands where it does.
What’s the correct order to renovate a bathroom?
The correct order is: plan and design, demo, rough-in plumbing and electrical, inspection, framing changes and waterproofing, install the tub or shower pan, wall and floor tile, prime and paint, then install the vanity, toilet, lighting, mirrors, and hardware last. Wet and structural work comes first; finishes go in from the walls out, ending with fixtures.
The governing principle is simple: build from the inside out and from dirty work to clean. Anything that lives behind a wall or requires inspection happens before the surfaces close up. Finishes go on after, in an order that protects each newly finished layer from the trade that comes next. Break that flow and you end up patching tile or repainting a wall a fixture just got installed against.
The step-by-step sequence
The full sequence runs eleven steps from design through final hardware. Demolition and rough-ins come early and need an inspection sign-off; waterproofing precedes any tile; paint happens before the vanity and fixtures go in; and the toilet, mirror, lighting, and hardware are the very last items installed so nothing finished gets damaged.
- Design and plan. Layout, fixtures, finishes, and selections all chosen before work starts.
- Demolition. Remove old fixtures, tile, and anything being replaced.
- Rough-in plumbing and electrical. Move or add supply lines, drains, and wiring.
- Inspection. Required sign-off on rough-in work before walls close (Fairfax County and most NoVA jurisdictions).
- Framing and waterproofing. Any wall changes, then a full waterproofing membrane in wet areas.
- Install tub or shower pan. Set before tiling so tile meets it cleanly.
- Tile walls and floor. Wet walls first, then floor, all over proper waterproofing.
- Prime and paint. Easier and cleaner before the vanity and fixtures are in place.
- Install vanity and countertop. The big finished pieces go in next.
- Set toilet and plumbing fixtures. Faucets, showerheads, and the toilet are connected.
- Lighting, mirror, and hardware. The final layer, installed last so nothing finished is at risk.
What comes first?
Planning comes first, always, before any demolition. Every fixture, tile, and finish should be selected and on order before the first wall opens, because rough-in plumbing and electrical depend on knowing exactly where the shower, vanity, and toilet will sit. Demolition is second, then the rough-ins that have to pass inspection before anything is closed up.
The single most expensive mistake is starting demo before the design is locked. If you have not chosen the vanity, the plumber does not know where to put the drain; if you have not chosen the shower system, the rough-in is a guess. Selections drive rough-in, rough-in drives everything after. This is the same “plan first” discipline that makes the broader curbless shower decision succeed or fail.
Common sequencing mistakes
The frequent errors: tiling before waterproofing (a leak waiting to happen), installing flooring before the messy trades scratch it, painting after the vanity and fixtures are in (slower and sloppier), and ordering nothing until demo is done, which causes delays when long-lead tile or vanities are not on site. Each adds cost or rework.
- Tile before waterproofing. Skipping or rushing the membrane is the cause of most shower leaks.
- Finishes installed before paint. Painting around a new vanity and fixtures is slower and never as clean.
- Ordering late. Tile and vanities can have long lead times; order during design, not after demo.
- Skipping the inspection. In Fairfax County and across NoVA, closing walls before a rough-in sign-off can mean reopening them.
How long does each phase take?
A typical full bathroom remodel runs about 3 to 5 weeks of construction, plus several weeks of design and ordering beforehand. Demo is 1 to 2 days, rough-in and inspection a few days, waterproofing and tile the longest stretch at 1 to 2 weeks, and fixtures and finishing the final few days. Lead times on tile and vanities, not labor, usually drive the overall calendar.
Plan for the lead times, not just the build. The actual on-site work is often only three to five weeks, but a custom vanity or imported tile can take longer to arrive than the entire construction phase. That is why we order everything during design: the goal is to have all materials on site before demo so the trades never wait. For a smooth project, the order of decisions matters as much as the order of work, which is the case for getting a designer to manage the whole sequence.

Frequently asked questions
What comes first in a bathroom remodel?
Planning and selections come first, before any demolition. Every fixture and finish should be chosen and ordered up front because rough-in plumbing and electrical depend on knowing exactly where everything sits. Demolition is second, followed by rough-ins that must pass inspection before walls close.
Do you tile before or after installing the shower pan?
After. The tub or shower pan is set first, then the wall and floor tile are installed to meet it cleanly, always over a full waterproofing membrane. Tiling before the pan, or before waterproofing, is a common mistake that leads to poor transitions and leaks.
Should I paint before or after the vanity goes in?
Paint before installing the vanity, toilet, and fixtures. Painting an empty room is faster, cleaner, and lets you cut clean lines without working around finished pieces. Do touch-ups at the very end, but the main painting belongs before the big finished items are set.
How long does a bathroom renovation take?
Construction is usually about 3 to 5 weeks, with waterproofing and tile the longest stretch. Add several weeks of design and ordering beforehand. Lead times on tile, vanities, and custom items often drive the overall schedule more than the labor does, so order early.
Do I need a permit to remodel a bathroom in Fairfax County?
Usually yes if you change plumbing, electrical, or walls; cosmetic swaps in the same layout often do not require one. Permitted work includes a rough-in inspection before walls close. Your designer and contractor handle the permit and inspection scheduling as part of the project.
