Licensed Seattle contractors delivering complete bathroom renovations with upfront pricing, quality materials, and warranties that protect your investment.
Hear from Our Customers
No more dealing with mold creeping back every few months because your ventilation can’t handle Seattle’s humidity. Your new bathroom is built specifically for our climate—proper moisture barriers, exhaust fans that actually move air, and materials that won’t deteriorate in constant dampness.
Your morning routine stops being a frustration. The layout makes sense for two people getting ready at once. Storage holds everything without the daily shuffle. Lighting shows what you’re actually doing instead of leaving you guessing.
When you eventually sell, buyers in Capitol Hill or Queen Anne won’t walk through calculating renovation costs. They’ll see a bathroom that’s already done right, with permits pulled and inspections passed. That’s the difference between a bathroom that adds value and one that becomes a negotiating point.
Sea Renovation has served Seattle homeowners since 2023, focusing on bathrooms, kitchens, and decks. We’re licensed, bonded, and insured because that’s what protects you when contractors are working in your home.
We’ve completed bathroom renovations in Craftsman homes in Ballard with original 1920s plumbing, mid-century houses in West Seattle that needed complete moisture remediation, and condos in Capitol Hill with complex HOA requirements. Each project taught us something about working with Seattle’s unique housing stock and strict SDCI permit requirements.
Military and first responder discounts are available—call for specific pricing on your project. We back our work with solid warranties because we’re still here when you need us, not disappeared to the next job in another state.
We start by looking at your actual space. Not a quick estimate over the phone, but measuring your bathroom, checking what’s behind those walls, and discussing what you need versus what’s realistic for your budget. If you’re in an older home between the Ship Canal and 85th Street, we’re already thinking about cast iron pipes and undersized drains that don’t meet current 2-inch code requirements.
Once you’re ready to move forward, we handle all SDCI permit applications and coordinate inspections. Seattle’s permit process typically adds 2-4 weeks to the front end, but we build that into your timeline so you’re not surprised. We submit the paperwork, schedule inspections, and make sure everything passes the first time.
Construction happens in stages: careful demolition, rough plumbing and electrical work, waterproofing and moisture barriers critical for Seattle’s climate, tile and finishing work, then final fixtures and cleanup. Most projects take 2-3 weeks once we start, and we protect the rest of your home from dust and debris throughout. You’ll know what’s happening each day and when you’ll have your bathroom back.
Ready to get started?
Your bathroom renovation includes everything from demolition through final fixtures: plumbing updates to meet current codes, electrical work with required GFCI outlets, proper waterproofing membranes behind all tile, high-CFM ventilation fans that handle Seattle’s humidity, and moisture-resistant materials that won’t fail in our climate.
We work regularly with Seattle’s older housing stock. Those beautiful Craftsman homes in Wallingford and Queen Anne often have galvanized pipes that need replacement, inadequate ventilation from decades before moisture management mattered, and small footprints that require creative space planning. We know how to maximize limited square footage while bringing everything up to current building codes.
Whether you’re converting a tub to a walk-in shower, renovating a master bathroom in a hillside home with drainage challenges, or updating a guest bath, we adapt our approach to your specific space. Every project includes our warranty coverage, military and first responder discounts when applicable, and the peace of mind that comes from working with contractors who understand Seattle’s unique requirements.
Seattle bathroom remodels typically range from $18,000 for a basic refresh to $45,000+ for a complete renovation with high-end finishes. The wide range reflects several Seattle-specific factors: labor rates here run $75-$125 per hour, about 15-20% higher than national averages due to our cost of living and skilled labor shortage.
What drives costs up? Plumbing changes in older homes often reveal cast iron pipes needing replacement. SDCI permits add $300-$1,500 depending on scope. Climate-appropriate materials like proper waterproofing membranes and high-CFM ventilation cost more but prevent the mold issues that plague cheaper installations in Seattle’s humidity.
We provide detailed estimates after seeing your specific bathroom because a 1940s Ballard bungalow has different challenges than a 2010 condo. Our goal is realistic numbers upfront, not lowball estimates that balloon once we open walls.
Most Seattle bathroom renovations take 2-3 weeks for construction once permits are approved. A simple fixture and tile update might complete in 10-14 days, while a full gut renovation with plumbing relocation and custom tile work takes closer to 4 weeks.
The bigger timeline factor is Seattle’s permit process. SDCI approval typically takes 2-4 weeks for standard bathroom work, longer if you’re in a historic district or making structural changes. We submit permits early and build this time into your project schedule so you’re not left waiting.
Older Seattle homes sometimes extend timelines when we discover issues during demolition—outdated wiring, hidden water damage, or plumbing that doesn’t meet current codes. We stop immediately, document everything, and discuss options before proceeding. Rushing bathroom work usually means redoing it later, which costs more than doing it right the first time.
Yes, most bathroom renovations in Seattle require permits through SDCI, especially if you’re moving plumbing, updating electrical, or making structural changes. Even projects under $6,000 need permits if they involve these systems. Simple fixture replacements without moving pipes typically don’t require permits, but anything beyond cosmetic updates usually does.
We handle the entire permit process for you—submitting applications, coordinating inspections, and ensuring everything meets Seattle’s building codes. This includes separate plumbing permits through Public Health Seattle-King County and building permits through SDCI. Some straightforward projects qualify for STFI permits that can be issued same-day.
Skipping permits creates problems when you sell. Buyers’ inspectors flag unpermitted work, which can kill deals or force price reductions. Proper permits protect your investment and ensure your bathroom renovation meets codes that exist for good reasons—like preventing mold growth and electrical hazards in wet environments.
Bathroom remodeling can happen year-round in Seattle since the work is indoors, but timing affects contractor availability and permit processing. Late winter through early spring (February-April) offers the best balance—contractors have more availability before the peak summer rush, and you’ll have your new bathroom ready before entertaining season.
Summer (June-September) is peak season when everyone wants projects done. Contractors are booked tighter and SDCI permit processing can slow down with higher volume. If you’re planning summer work, book 2-3 months ahead.
Winter renovations are completely feasible and sometimes offer pricing advantages since demand is lower. Seattle’s rainy season doesn’t affect indoor bathroom work, though any exterior ventilation installation needs dry weather. The key is planning around your schedule and holidays when you need your bathroom functional for guests.
Start by verifying Washington State contractor licensing through the Department of Labor and Industries website. Every legitimate contractor should have an active license, bonding, and liability insurance. Ask for proof—licensed contractors provide this without hesitation.
Look for Seattle-specific experience. A contractor who understands SDCI permit requirements, knows how to work with older homes in neighborhoods like Queen Anne and Ballard, and recognizes moisture management challenges in our climate will save you headaches. Ask about recent projects in Seattle and request references you can actually contact.
Get detailed written estimates that break down costs—not just a total number. Compare what’s included: permits, materials, labor, warranty coverage. The lowest bid often means corners cut on waterproofing or ventilation, which creates expensive problems later in Seattle’s humid climate. Choose contractors who explain what they’re doing and why, not just what it costs.
In Seattle’s competitive real estate market, proper moisture management adds more value than luxury finishes. Buyers here know to check for mold and ventilation issues. High-CFM exhaust fans, waterproof membranes behind tile, and moisture-resistant materials signal a bathroom that won’t become a problem.
Walk-in showers with curbless entry appeal to Seattle’s aging population planning to stay in homes longer. They’re also popular with younger buyers who prefer modern aesthetics over tubs. Heated floors are considered affordable luxury here—they add comfort during our long rainy season and help dry bathrooms faster.
Storage solutions matter in Seattle’s older homes where bathrooms are typically small. Built-in niches, floating vanities with drawers, and medicine cabinets that actually hold things make limited space functional. Energy-efficient fixtures and LED lighting appeal to Seattle’s environmentally-conscious buyers. Most importantly, permitted work with passed inspections protects your investment when you sell.
