I get this question at least three times a week. Someone in Twin Lakes or Marine Hills calls up, says they want to redo a bathroom, and asks me to throw out a number. Here’s the honest answer.
A bathroom remodel in Federal Way typically costs $15,000 to $22,000 for a budget refresh, $28,000 to $45,000 for a solid mid-range gut job, and $55,000 to $85,000+ for a high-end master bath overhaul. Most of the homeowners I work with in South King County land in the $30,000-$40,000 range for a full remodel of a standard 5×8 hall bath.
Those numbers aren’t pulled from a national database. They’re from jobs we’ve actually bid and built in Federal Way, Auburn, and Kent over the past two years.
Why Bathroom Costs Vary So Much
I’ve done $12,000 bathrooms and $90,000 bathrooms within five miles of each other. The difference usually comes down to three things: how much you’re moving, what you’re putting in, and what’s hiding behind the walls.
A cosmetic refresh where we keep all the plumbing where it is? That’s one thing. Ripping out a tub to build a curbless walk-in shower with a linear drain? Completely different job.
And then there’s the surprise factor. Half the houses in the Mirror Lake and Steel Lake neighborhoods were built in the 70s and 80s. I’ve opened up walls expecting standard drywall and found old galvanized pipe that needs replacing, mold behind the tile backer, or subfloor rot from a slow leak that’s been going for years. That’s why I always tell people to budget a contingency.
The Cost Breakdown: Where Your Money Actually Goes
Here’s roughly how a typical Federal Way bathroom remodel budget splits out:
- Labor: 40% — Skilled tile setters, plumbers, and electricians aren’t cheap in the Seattle metro. And they shouldn’t be. A bad tile job or a leaky shower pan will cost you way more to fix later.
- Materials: 35% — Tile, vanity, toilet, fixtures, shower door, backer board, waterproofing membrane. This is where your choices make the biggest difference in the final number.
- Permits and design: 10% — Federal Way residential building permits for a bathroom remodel run $400 to $800 depending on scope. If you’re adding or moving plumbing, you’ll need a plumbing permit too. The City of Federal Way community development department handles these.
- Contingency: 15% — I build this into every quote. On older homes in Dash Point or the hillside neighborhoods near Redondo, I’ve seen the contingency get used on almost every job. On newer construction, sometimes we don’t touch it and the client gets money back.
Budget Tier: $15,000 – $22,000
This is a surface-level refresh. We’re keeping the layout exactly the same. No walls move, no plumbing moves.
What you get:
- New vanity and top (stock from Home Depot or Floor & Decor — I like the Glacier Bay line for budget jobs, honestly)
- New toilet (Kohler Highline or TOTO Drake — both solid, both around $300-$400)
- Re-tile the tub surround with ceramic subway tile
- New fixtures (faucet, showerhead, towel bars)
- Fresh paint, new mirror, new lighting
- New flooring — luxury vinyl plank is the move here, $3-$5/sqft installed
What you don’t get: new tub, layout changes, heated floors, frameless glass.
Timeline: 2-3 weeks from demo to done.
This is the right call if your bathroom is functional but ugly. I do a lot of these for folks getting homes ready to sell.
Mid-Range: $28,000 – $45,000
This is the sweet spot. Most of my Federal Way clients end up here. Full gut, new everything.
What you get:
- Complete demo down to studs
- New Kerdi or RedGard waterproofing system (non-negotiable — I won’t skip this)
- Porcelain tile floors and shower walls ($6-$12/sqft for material)
- New tub or tub-to-shower conversion
- Semi-custom vanity (36″ to 60″ depending on space)
- Quartz or solid surface countertop
- Chrome or brushed nickel fixtures from Delta or Moen (their mid-tier lines are genuinely good)
- Recessed lighting on a dimmer
- Exhaust fan upgrade — code requires it vented to exterior, and I’m amazed how many bathrooms I open up where the old fan just vents into the attic. That’s a mold factory.
- New drywall, paint, trim
Timeline: 4-6 weeks. Could be faster but I don’t like to rush tile work. Proper cure times matter.
The biggest cost driver in this tier is tile selection. A $4/sqft ceramic vs a $15/sqft large-format porcelain changes the materials line by $2,000-$4,000 easily. And large-format tile takes longer to install — more cuts, more precision, more labor.
High-End: $55,000 – $85,000+
Master bath territory. Typically in the bigger homes up in Twin Lakes, Marine Hills, or some of the newer builds near The Commons.
What you get:
- Everything in mid-range, plus:
- Curbless/barrier-free shower with linear drain
- Frameless glass enclosure (these alone run $2,500-$4,500 installed)
- Heated tile floors (Schluter DITRA-HEAT or NuHeat — $800-$1,500 for a typical bathroom)
- Double vanity, custom or high-end semi-custom
- Natural stone or premium porcelain (think large-format Dekton or Neolith panels)
- Free-standing soaking tub if the space allows
- Smart toilet or bidet seat
- Custom niches, bench seating in shower
- Potentially moving walls or plumbing to open up the layout
Timeline: 6-10 weeks depending on complexity and lead times on custom orders.
At this level, material lead times are your biggest enemy. Custom glass, specialty tile, free-standing tubs — some of this stuff has 4-6 week lead times even when you order early. I always tell clients: pick your materials before we start demo. Sitting with a gutted bathroom for three weeks waiting on a backordered vanity is no fun.
Federal Way Permit Details
You need a permit for most bathroom remodels in Federal Way. Here’s what I tell clients:
- Cosmetic only (paint, mirror, accessories): No permit needed.
- Replacing fixtures in the same location (new vanity, new toilet in same spot): Usually no permit, but check with the city.
- Any plumbing changes (moving drain, adding a line): Plumbing permit required.
- Electrical changes (new circuits, moving outlets, adding lighting): Electrical permit required.
- Structural changes (removing or modifying a wall): Building permit required.
Permit fees for residential bathroom work in Federal Way typically run $400-$800. I handle the permit process for all my clients — it’s part of the service. The inspections are straightforward if the work is done right.
Washington state also requires your contractor to be registered with the Department of Labor & Industries (L&I). You can look up any contractor at lni.wa.gov. If they’re not registered, walk away. More on that in our guide to choosing a general contractor.
How to Keep Costs Down Without Cutting Corners
A few things I tell every client:
Don’t move the plumbing. Keeping the toilet, vanity, and shower/tub in their current locations saves $3,000-$5,000 easily. Every drain you move means cutting into the subfloor and possibly the joists below.
Pick your tile from in-stock options. Special-order tile is beautiful but adds lead time and cost. Floor & Decor in Tukwila has a massive selection of in-stock porcelain that looks great.
Spend on the shower waterproofing, not on gold-plated fixtures. I’ve seen people cheap out on the waterproofing membrane and then spend $800 on a rain shower head. That’s backwards. A leaky shower costs $10,000+ to fix. A nice showerhead costs $150.
Stock cabinets with a nice countertop look better than a custom vanity with a cheap top. I’ve done this combo dozens of times and clients are always surprised how good it looks.
What About Those Online Estimates?
Every few months a client comes to me with a number from HomeAdvisor or some online calculator that says they can remodel a bathroom for $8,000. In Federal Way. In 2026.
I don’t know where those numbers come from. Maybe a different market. Maybe a different decade. What I know is that a licensed, bonded, insured contractor in South King County paying real wages to skilled tradespeople and pulling proper permits cannot do a quality full bathroom remodel for $8,000. If someone quotes you that, ask what they’re leaving out.
