A Contractor Who Actually Knows Seattle Bathrooms

Seattle bathrooms are where the age of the housing stock really shows. Craftsman bungalows and foursquares in Ballard, Wallingford, and Beacon Hill were built between 1900 and 1930, and their original baths tend to sit on cast-iron drains, galvanized supply lines, and unreinforced subfloors that have been quietly soaking for decades under old tile. Newer condos and townhomes on Capitol Hill and around South Lake Union flip the problem — tight stacks, HOA approvals, and building-access windows to work around.

We're based in Kent and in Seattle constantly — Queen Anne, Green Lake, Magnolia, West Seattle, and the rest. Water is unforgiving, and in homes this old the difference between a bath that lasts five years and one that lasts thirty is what happens under the tile. We waterproof to a real system, not a coat of hope, and we price the hidden rot honestly instead of finding it after you've signed. Plenty of Seattle clients pair the bath with a kitchen remodel or a full whole-home renovation, and we hold the same waterproofing standards on bathroom remodels over in Bellevue.

What's Included

A Complete Seattle Bathroom, Waterproofed to Last

Bathrooms leave no room for shortcuts — water, ventilation, and tight clearances all have to cooperate, especially in Seattle's damp climate. Here's what a Seattle bathroom project usually covers, and we build every estimate around your own home.

Tile & Stone

Floor tile, large-format wall tile, custom shower niches, slab walls, and proper substrate (Schluter, cement board) under everything.

Vanities & Cabinetry

Stock, semi-custom, and custom vanities. Wall-mounted, single-sink, and dual-vanity layouts with soft-close hardware.

Plumbing

Toilet, sink, shower valve, and tub installation. Relocating drains, replacing old galvanized and cast-iron lines common in Seattle homes, and rough-in for new fixtures.

Fixtures

Faucets, showerheads, body sprays, handheld wands, tub fillers, towel bars, and hardware — coordinated with your aesthetic.

Lighting

Vanity sconces, recessed lighting, decorative pendants, and dimmer-friendly switching. Always to code, always GFCI-protected.

Waterproofing

Schluter Kerdi, Wedi, or hot-mopped pans. Proper waterproofing under tile is the difference between a 5-year and 30-year bathroom.

Ventilation

Exhaust fans sized for the room, vented to the exterior (not the attic) — critical in Seattle's damp climate — with humidity-sensing controls when requested.

Glass & Doors

Frameless shower glass, custom hinged or sliding panels, and barn-door hardware. Measured and templated after the tile is set.

Permits & Inspections

We pull City of Seattle (SDCI) permits when plumbing or electrical work is involved, and we schedule the rough-in and final inspections.

Seattle Permits & Considerations

Permitting a Bathroom Remodel in Seattle

The City of Seattle requires a permit through the Seattle Department of Construction & Inspections (SDCI) any time a bathroom remodel involves plumbing relocation, electrical changes, or structural alterations. A like-for-like fixture swap (same toilet location, same vanity footprint) often doesn't — but moving a shower drain, adding a circuit, or changing the layout always does, and Seattle enforces it more tightly than the suburbs.

We pull every required permit through SDCI, coordinate the rough-in and final inspections, and keep documentation in your project file. Bathroom permits matter especially at resale in Seattle, where inspectors and appraisers routinely flag undocumented work in older homes.

  • Permits filed with SDCI under our license, not yours
  • Rough-in and final inspections scheduled and met on-site
  • We plan around Seattle's longer plan-review timelines so your schedule is realistic from day one
  • Permit copies handed to you at close-out for resale records

Honest Pricing

What a Bathroom Remodel Typically Costs in Seattle

Seattle sits at the higher end of the Puget Sound bathroom market — labor, access, and the surprises inside older homes push costs above the south-end suburbs. Below are the typical ranges we see; actual numbers depend on shower size, tile selection, vanity choice, and whether plumbing moves.

Refresh
$12,000 – $22,000

New vanity, toilet, fixtures, tile floor and lighting. Original layout, no plumbing relocation.

Mid-Range Remodel
$22,000 – $38,000

Custom shower with tile, new vanity and counters, full plumbing fixtures, ventilation, waterproofing, and lighting. Most common project here.

Full Primary / Custom
$38,000 – $55,000+

Layout changes, large walk-in shower, frameless glass, dual vanities, premium tile, heated floors, and designer fixtures.

Ranges are typical Seattle bathroom project costs and don't include unforeseen issues (rot under old tile, galvanized or cast-iron line replacement) — we flag those in writing the moment we find them.

Seattle Bathroom Remodel FAQs

What Seattle Homeowners Ask About Bathroom Remodels

Who pulls the SDCI permits for a bathroom remodel?
We do. If your Seattle bathroom remodel involves plumbing, electrical, gas, or structural work, it needs a permit from the Seattle Department of Construction & Inspections (SDCI). We file it under our license and take care of the application, inspection scheduling, and code compliance for you.
How long will my Seattle bathroom remodel take?
Most Seattle bathroom remodels run 3 to 7 weeks of active construction. A straightforward hall-bath update wraps in 2–3 weeks, while a primary bath with custom tile, frameless glass, and a new layout usually takes 5–8 weeks — plus 2–4 weeks of design and SDCI permitting beforehand. Older Seattle homes can add a few days once old plumbing or rotted subfloor turns up.
What should a bathroom remodel cost in Seattle?
Most Seattle bathroom projects fall between $12,000 and $55,000. A mid-range hall bath with a new tile shower, vanity, and fixtures usually runs $22,000–$38,000, while primary suites with dual vanities, frameless glass, and heated floors trend higher. Seattle runs above the south-end suburbs on labor and access, and you'll always get an itemized estimate.
Which Seattle neighborhoods do you remodel bathrooms in?
Ballard, Fremont, Wallingford, Green Lake, Queen Anne, Magnolia, Capitol Hill, West Seattle, Beacon Hill, and the rest. The old baths in these neighborhoods routinely hide cast-iron drains and rotted subfloor beneath the tile, and we know how to plan around it before demo starts.
Are you licensed, bonded, and insured to work in Seattle?
Yes. Big Build Construction holds full Washington State licensing, bonding, and insurance, and that covers the City of Seattle. Every bathroom is built to code and inspected wherever the permit requires it.
You're in Kent — can you still take on a Seattle bathroom?
Yes. Most Seattle neighborhoods are about 25 minutes up I-5 and we're working there constantly. For standard-scope hall and primary baths, the typical stretch from consultation to demo is 2–5 weeks, once SDCI permitting clears.
Can I hear from past Seattle bathroom clients?
Yes — we've completed bathrooms in Ballard, Wallingford, Queen Anne, West Seattle, and Beacon Hill, and we're happy to share contact details for past clients in or near your neighborhood.
