How Much Does a Bathroom Remodel Cost in Seattle, WA? (2026 Guide)

Quick Answer

A bathroom remodel in the Seattle, WA area costs $15,000 to $25,000 for a mid-range refresh, $25,000 to $40,000 for a master bath upgrade, and $50,000 or more for a full custom build with structural changes. Most Seattle homeowners spend $25,000 to $35,000 for a complete bathroom renovation in 2026.

These ranges reflect actual project costs in King, Snohomish, Pierce, and Kitsap counties, and assume work by a licensed contractor including labor, materials, permits, and finishing.

Cost Breakdown by Project Size

The single biggest variable in a Seattle bathroom remodel is the scope. A surface refresh is wildly different from a full gut.

Small bathroom refresh — $10,000 to $18,000

A "refresh" keeps the existing layout but swaps out finishes and fixtures:

• New vanity and countertop ($1,500–$3,500)
• New toilet ($400–$900 installed)
• New tile flooring ($1,800–$3,500 for ~50 sq ft)
• New shower or tub fixtures, no relocation ($800–$2,500)
• Fresh paint and trim ($600–$1,200)
• Labor: 1–2 weeks

This works well in guest baths and powder rooms where the layout already functions. Most homes in Ballard, Wallingford, and West Seattle bungalows can absorb this scope without permits.

Mid-range bathroom remodel — $20,000 to $35,000

The most common Seattle bathroom project. Includes everything above plus:

• Full tile shower with glass enclosure ($4,500–$8,000)
• New vanity, mirror, lighting upgrades ($2,500–$4,500)
• Heated tile floors (popular in PNW for cold mornings — $1,200–$2,500 add-on)
• Plumbing relocations within the same wall ($1,000–$2,500)
• Drywall, insulation, and waterproofing replacement
• Possible electrical upgrades for new lighting/heated floors

Mid-range projects usually need a permit if you change plumbing or electrical layout. Plan 4–6 weeks from demo to final.

Master bathroom remodel — $35,000 to $55,000

A master bath is bigger and includes more premium features:

• Walk-in shower with custom tile and bench ($8,000–$15,000)
• Freestanding soaking tub ($2,500–$5,000 + $1,500 install)
• Double vanity with quartz or stone tops ($4,500–$9,000)
• Smart toilet or bidet add-on ($1,500–$3,500)
• Underfloor heating throughout
• Skylight or window upgrades for natural light

This scope normally requires permits in any city in King County and adds 5–10% in fees to the total project cost.

Full custom or layout change — $50,000 to $100,000+

When the layout itself changes — moving the toilet, expanding the footprint into a closet, combining two small baths into one master suite — costs jump significantly. This requires structural work, possibly relocating soil stacks (waste lines), HVAC reroutes, and full electrical re-permits.

In Seattle and Bellevue's higher-end neighborhoods (Magnolia, Capitol Hill, Somerset), full custom master baths frequently land between $60,000 and $100,000.

What Drives Bathroom Remodel Costs in Seattle

Five factors most affect the final price:

1. Plumbing changes. Moving a toilet or shower drain involves cutting and re-routing the soil stack. In a Craftsman bungalow with a slab or crawlspace, this can add $3,000–$8,000.

2. Tile selection. Standard ceramic runs $4–$8 per sq ft installed. Mid-grade porcelain $9–$15. Custom mosaic, large-format slab, or natural stone runs $20–$50+ per sq ft installed.

3. Vanity and countertop. A stock vanity is $400–$1,200. A custom, soft-close, full-extension vanity from a Seattle-area cabinet maker is $2,500–$6,000 plus the countertop ($800–$3,000).

4. Shower glass. A frameless glass enclosure costs $1,800–$4,500 depending on size and hardware. This is often skipped on tight budgets but adds significant resale value.

5. Permits and inspections. City of Seattle, Bellevue, and Tacoma all require permits for plumbing, electrical, and structural work. Permit fees, plan review, and required inspections add 5–10% to total project cost, plus 2–4 weeks to the timeline.

Pacific Northwest-Specific Cost Factors

Bathrooms in the Seattle area face conditions that drier climates do not, and cost estimates need to account for this:

• Waterproofing. Heavy rainfall and high humidity make proper waterproofing non-negotiable. We use Schluter Kerdi or RedGard membrane systems behind tile — $1,500–$3,000 add-on but it prevents the moisture damage and mold problems endemic in older PNW homes.
• Mold remediation. Many homes built before 1990 have hidden mold behind shower walls. If found during demo, remediation runs $1,500–$5,000 before any new work begins.
• Vent fan upgrades. Code requires properly sized exhaust fans (50+ CFM) ducted to the exterior. Many older Seattle homes have undersized fans or fans that vent into the attic — adding to mold risk. Upgrading runs $400–$900 installed.
• Insulation. Removing tile usually exposes outdated insulation. Bringing exterior bathroom walls to current King County code (R-21) costs $400–$1,000 but lowers heating bills long term.

Bathroom Remodel Cost by City (Seattle Metro)

City labor rates and permit costs vary across the Seattle metro area:

AreaMid-range bathroomMaster bathSeattle (Ballard, Capitol Hill, West Seattle)$24K–$36K$38K–$58KBellevue / Mercer Island$26K–$38K$42K–$62KKirkland / Redmond / Sammamish$25K–$36K$40K–$58KTacoma / Lakewood$20K–$30K$32K–$48KEverett / Lynnwood$22K–$32K$36K–$52KRenton / Kent / Federal Way$22K–$32K$34K–$50K

Bellevue tends to run higher because of Eastside material expectations and slightly stricter inspection schedules. Tacoma and Kent run lower on labor.

Permit Costs and Timeline

Most full bathroom remodels in the Seattle area require a building permit:

• Seattle (SDCI): $300–$800 for a Subject-to-Field-Inspection (STFI) permit, plus $200–$500 in plan review. Most bathroom remodels qualify for STFI which is faster (2–4 weeks turnaround).
• King County (unincorporated): $400–$900 base, plus $100+ per inspection.
• Bellevue: $500–$1,200 typical for full remodel.
• Tacoma / Pierce County: $250–$700.

For permit-heavy projects, plan a 3–4 week front-end delay before demo can start. Some projects qualify for over-the-counter permits which can issue same-day.

Bathroom Remodel ROI in Seattle

According to the 2025 Cost vs Value Report regional data for Pacific (Seattle), midrange bathroom remodels return roughly 66% of their cost at resale, and minor cosmetic upgrades return up to 80%. In Seattle's strong housing market, well-executed bathroom remodels frequently appraise for more than the project cost — particularly in Bellevue, Sammamish, Mercer Island, and Capitol Hill.

Can I remodel a bathroom in Seattle for under $20,000?Yes — a refresh that keeps the existing layout and uses mid-grade finishes can come in under $20,000. The main constraint is plumbing: if you don't move the toilet, tub, or shower drain, you stay in the affordable range.
