What drives bathroom remodel cost in Seattle
- Whether you keep or move the toilet, sink, and shower drains (moving drains is the biggest cost driver)
- Tile square footage and pattern complexity, plus the waterproofing behind a walk-in shower
- Fixture tier: builder-grade vs mid vs designer faucets, valves, and glass
- Hidden water damage or old plumbing found once the walls open up
- Ventilation and any electrical work for heated floors, lighting, or an upgraded fan
Permits for a bathroom remodel in Seattle: Seattle Department of Construction and Inspections (SDCI)
In Seattle, bathroom remodel permits are issued by the Seattle Department of Construction and Inspections (SDCI). Seattle SDCI issues permits through the Seattle Services Portal. Many smaller remodels qualify as a Subject-to-Field-Inspection (STFI) permit, which needs no pre-submittal appointment, while larger additions and alterations follow the standard Addition or Alteration permit path. You create a portal account to apply and to schedule inspections.
Typical timeline: Seattle does not publish one fixed approval time for all remodels. Subject-to-Field-Inspection permits for qualifying small projects are the faster path because plan details are verified in the field, while full addition or alteration permits take longer. Confirm your project type with SDCI.
Local note: Seattle offers a Subject-to-Field-Inspection track for qualifying small remodels, where the work is checked by an inspector in the field instead of through full up-front plan review, which is a distinct SDCI process not offered the same way in the California cities on this list.
Swapping a vanity or re-tiling in place is usually permit-free, but relocating plumbing fixtures, adding electrical, or altering the layout typically needs a permit. Waterproofing and shower-pan work is inspected in many jurisdictions because a failed pan causes structural rot. Confirm plumbing and electrical permit triggers with the local building department before demolition.

When you need a licensed pro
A licensed plumber and electrician are required for any drain relocation or new circuits, and shower waterproofing is best left to a pro because failures are expensive and hidden. Cosmetic swaps can be homeowner-led, but wet-area work should run through a licensed contractor.
Questions to ask a Seattle contractor
- Does the bid assume the plumbing stays in place, or is drain relocation included?
- How are you waterproofing the shower, and is that step inspected here?
- What is your plan if we find water damage or old pipes once the walls are open?
