BeforeAfterThe finish standard we hold you to
Drag the handle across. These two frames are a kitchen project, shot from one camera position with no staging in between.
We show a kitchen here because tile setting, waterproofing and cabinet work are the same trades that build a bathroom, and this is the standard we hold on both. Ask at the estimate and we will walk you through bathroom work in person.
See the galleryOur team provides GFCI-compliant electrical updates and bathroom cabinet fabrication, delivering high-impact, low-footprint finishes for homes and personalized bathroom solutions for both residential and commercial projects. Backed by a Washington State contractor license and general liability insurance, we take on work at every scale, from under-stair powder rooms to new half baths cut into an entry hall.
From setting a wall-hung carrier inside the stud bay so the sink floats clean off the wall, to lighting a mirror with two sources a foot apart, our team handles every detail. Serving Bellevue and neighboring Mercer Island, Newcastle and Renton, we ensure fast, efficient service and deliver reliable, professional, beautiful results on every powder room project.

A Half Bath Is a Toilet and a Sink
That is the entire definition, and it is also the entire cost story. A half bath, which everyone calls a powder room once it sits near the entry, has no shower, no tub and no wet area. Which means no shower pan, no waterproofing membrane, no flood test, no glass enclosure, no valve, no tile surround and no shower drain.
Strip all of that out and what is left is a small room with a toilet, a sink, a light, a mirror and a floor. Most Bellevue powder rooms run 15 to 25 square feet, smaller than any other bathroom in the house by a wide margin.
It is also the most public room you own. Guests never see the primary suite. They always see this one.
What a Powder Room Remodel Includes
- Demolition, disposal, containment and floor protection through the entry
- Plumbing for the sink and toilet supply, drain and vent, with new shutoffs
- Electrical: GFCI protection at the receptacle, IP44 rated fixtures, and two light sources flanking the mirror at least a foot apart so faces light evenly
- Exhaust ventilation where the room has no operable window
- Floor tile, wall tile or wallcovering
- Vanity, floating vanity, pedestal sink or wall-hung basin
- Vanity top and sink, or an integrated basin
- Toilet, towel bars, paper holder and accessories with blocking behind them
- Mirror, sconces and trim
- Paint, punch list and final walkthrough
The One Room Where You Can Be Bold
A powder room is 20 square feet of material. The same zellige that would cost a fortune across a primary bath covers this entire room for the price of a decent vanity. That changes what is worth doing.
Zellige brings hand-glazed variation that no machine-made tile imitates, and its irregularity reads as intentional at this scale. Encaustic carries its pattern through the full thickness of the body, so the design does not wear away even in a room that gets heavy guest traffic. Mosaic, glass, metal and terracotta all work here for the same reason: the quantity is small enough that the per-square-foot number stops mattering.
Layout is free to be dramatic too. Herringbone, chevron, basket weave, pinwheel and diagonal settings all cost labor, not material, and in a room this size the labor difference is a day.
Natural stone is genuinely reachable here. Marble, onyx, granite and slate vary in color and pattern slab to slab, which normally demands planning and dry layout. In a powder room you need one remnant, so a dramatic piece of onyx behind a wall-hung basin is a real option rather than a fantasy.
Half Bath and Powder Room Cost in Bellevue
Read this first. The published 2026 Seattle and Eastside bathroom figures start at $18,000 for a cosmetic full bathroom. No published survey isolates powder rooms, because they sit below the bottom of that data. The ranges below are scaled down from those figures to reflect a room with no shower, no waterproofed pan, no tub and no glass, and they are our own scaled estimate rather than a quoted survey number.
| Scope | Scaled Bellevue range | What it covers |
|---|---|---|
| Cosmetic powder room refresh | $6,000 to $12,000 | New toilet, sink, faucet, light, mirror, paint, floor tile |
| Full powder room rebuild, 15 to 25 sq ft | $10,000 to $20,000 | Everything out and everything new, same fixture locations |
| Powder room with plumbing relocation | $18,000 to $30,000 | Sink or toilet moved, wall opened, drain and vent rerouted |
| Adding a new half bath | $25,000 to $45,000 | New room framed, plumbing run, vent added, permit and inspection |
What moves the number:
- Whether the plumbing moves. Keeping the toilet flange where it is saves more than any material choice on the list.
- Home age. A large share of Bellevue's 64,688 housing units predate 1975, and older powder rooms hide galvanized supply lines and undersized venting.
- Wall tile coverage. Floor only, wainscot height, or floor to ceiling. That decision doubles or halves the tile labor.
- Fixture specification. A wall-hung basin needs an in-wall carrier and a concealed trap, which is framing work a pedestal sink does not require.
- Cabinetry quality. A furniture-grade floating vanity built to the opening costs more than a stock 24 inch box and is usually the thing guests actually notice.
- Material specification. Ceramic and cultured marble at one end, zellige, stone remnant and engineered quartz at the other.
How the Project Runs
- Free in-home estimate. We measure, check the vent, the shutoffs and the receptacle, and talk budget.
- Selections. Tile, fixture, vanity, mirror and lighting, all specified before demolition because the room is too small to improvise in.
- Permits. A like-for-like refresh usually needs none. Moving a drain or adding a new half bath does, and we pull City of Bellevue permits inside the contract.
- Demolition. Typically one day.
- Plumbing and electrical, then inspection where the scope requires it.
- Tile, vanity, top, fixtures, mirror and lighting.
- Paint, punch and walkthrough.
One to two weeks on site for a rebuild in the existing footprint. Three to five weeks when a new half bath is being framed and plumbed from scratch.
Adding a Half Bath Where There Is None
Older Bellevue houses frequently have three bedrooms and one bathroom. A main-floor powder room is the highest-return square footage in that house, and it needs less room than owners expect: roughly 3 by 6 feet plus access to a drain line and a vent.
The usual candidates are under a staircase, the end of a coat closet, or a corner of a laundry room already carrying a drain. The constraint is rarely floor area. It is how far the new drain must travel to reach an existing stack. If the answer is far, see bathroom additions, or basement bathroom remodeling when the room sits below the sewer line and needs pumped drainage.

If the room has a shower, it is not a half bath. A compact full bath is covered on our small bathroom remodeling page, and a corridor bath on guest and hall bathroom remodeling. Moving a powder room to a better spot in the plan is a bathroom layout reconfiguration. A 1950s powder room with original fittings may be worth keeping, which is historic and vintage bathroom renovation.
Every room type is listed on our Bellevue bathroom remodeling page. Owners doing statement tile in two rooms at once should also see kitchen backsplash installation, and the home page carries the full service list.

Why Bellevue Homeowners Choose Us
Small rooms get the same crew. A powder room is not a filler job. It gets the tile setter who does our primary baths.
Blocking goes in the walls. Towel bar, paper holder, wall-hung basin carrier. Cheap at rough-in, impossible afterward.
We light the mirror properly. Two IP44 rated sources at least a foot apart. One overhead can is why most powder rooms photograph badly.
Licensed and insured. a Washington State contractor license and general liability, with certificates issued before work starts.
We protect the entry. This room usually sits off the front hall, so floor protection and containment start at the door.
Frequently Asked Questions
Straight answers, from the questions we get asked at the estimate.
How much does a powder room remodel cost in Bellevue?
A cosmetic refresh runs roughly $6,000 to $12,000 and a full rebuild in the same footprint roughly $10,000 to $20,000. These are scaled estimates, not published survey figures, because powder rooms sit below the bottom of the Seattle and Eastside cost data.
What is the difference between a half bath and a powder room?
Nothing structural. A half bath has a toilet and a sink and no shower or tub. It gets called a powder room when it sits near the entry and serves guests.
How long does a half bath take?
One to two weeks on site for a rebuild in the existing footprint. Three to five weeks when the room is being framed and plumbed from scratch.
Can you add a half bath to my house?
Usually yes. It needs about 3 by 6 feet plus access to a drain and a vent. Under a staircase, at the end of a closet or beside a laundry room are the common spots.
Do I need a permit?
A like-for-like refresh usually does not. Moving a drain or building a new half bath does, and we pull City of Bellevue permits inside the contract.
Do you offer free estimates?
Yes. Free in-home estimates with no obligation, usually within three business days. Call (940) 209-3977.
Is expensive tile worth it in a room this small?
Often, yes. Twenty square feet of zellige or encaustic costs less than most vanities, and every guest sees it.
Do you serve my ZIP code?
Bellevue 98004 through 98009, Mercer Island 98040, Kirkland 98033 and 98034, Redmond 98052 and 98053, Sammamish 98029, 98074 and 98075, and Issaquah 98027.
