Bathrooms are small rooms with expensive problems. Water, tile and plumbing all meet in a few square feet, and the cost depends less on size than on what you change. Here are typical 2026 costs for Seattle-area bathroom projects and what moves the price.

Why waterproofing matters more than tile
Most failed bathrooms we tear out in the Seattle area failed behind the tile. Tile set over drywall, a shower pan without a proper membrane, or an unvented exhaust fan lets moisture into studs and subfloor. In Seattle’s damp climate, that becomes rot and mold within a few years. A proper remodel includes a full waterproofing membrane on walls and pan, sealed seams and niches, and a flood test before tile goes on.
What changes the price
- Moving plumbing — relocating a toilet, shower or vanity adds plumbing work and usually a permit.
- Tile choice — large-format, natural stone and mosaic tile take more labor than standard porcelain.
- Hidden damage — rot or mold behind old tile must be repaired before rebuilding.
- Shower glass — frameless glass costs more than framed doors or a curtain.
- Room size — primary bathrooms need more tile, fixtures and time.
Tub-to-shower conversions
One of the most requested projects in older Seattle homes. The tub is removed, the base is rebuilt and waterproofed, and a low-curb or curbless tiled shower takes its place. It makes small bathrooms feel larger and is easier and safer to use — a common choice for aging in place.
How long will I be without a bathroom?
A full remodel usually takes 3–6 weeks of construction. If it’s your only bathroom, ask your contractor to phase the work and keep the out-of-service window as short as possible.
FAQ
Do I need a permit to remodel a bathroom in Seattle?
Usually when you move plumbing, add circuits, change walls or add a fan duct. Replacing fixtures in place often doesn’t need one.
Can I save money by keeping the tub?
Yes — re-tiling around an existing tub in good condition costs less than a conversion, as long as the walls behind are dry and sound.
