Go Far®What counts as a small bathroom
Most of the bathrooms in Snohomish and King County homes are small by design: a powder room (a sink and toilet in roughly 15–25 square feet), and the classic 5x8 hall or guest bath — about 40 square feet with a tub-shower, a vanity, and a toilet in a row. If that is your room, this guide is your budget. Larger baths and primary suites price differently — our full bathroom remodel cost guide covers those.
The honest ranges
- Powder room remodel: roughly $8,000–$18,000. No tub, no shower, no waterproofing — which is why it is the least expensive real remodel in the house. New vanity, faucet, toilet, tile floor, lighting, mirror, and paint transform the room guests actually see.
- Small-bath refresh: roughly $10,000–$18,000. Keep the tub and tile where they are; replace the vanity, toilet, fixtures, flooring, lighting, and paint. The best value tier when the existing tub and layout are sound.
- Full small-bath remodel: roughly $20,000–$35,000. The room goes to the studs — new tub or walk-in shower, new tile, new everything — with fixtures staying in roughly the same locations. This is the bottom of the Seattle-area full-remodel band, which runs $20,000–$60,000 with primary baths at the top.
- Reconfigured or expanded small bath: $35,000 and up. Moving the toilet, stealing closet space, or converting tub to curbless shower with a linear drain adds plumbing, framing, and structural work — premium-tier pricing in any size room.
Why a small bathroom isn’t cheap per square foot
A 40-square-foot bathroom routinely costs more per square foot than any other room in the house, and it helps to know why so the estimate makes sense. Every trade still shows up: plumber, electrician, tile setter, drywaller, painter, and the crew that ties it together — each with a minimum worth of mobilization no matter the room size. The room is nearly all fixtures and tile, the two most expensive things per square foot in construction. And behind the walls, a remodel is when failing shutoffs, corroded galvanized supply lines, and missing ventilation get fixed properly — small line items that exist in every bath, big or small. The result: the total is modest, but the per-square-foot number looks bold. Judge small-bath bids on the total and the scope, never the square footage.
Where to spend in a small bath
Small rooms reward good decisions more visibly than big ones. The money that shows: tile — large-format tile with minimal grout lines makes a 5x8 room read bigger, and a tiled shower with a glass panel instead of a framed door removes the visual wall; a floating or narrow-depth vanity that frees floor area; a recessed niche instead of shelves hanging into the shower; layered lighting — a small bath with one ceiling fixture always looks like a small bath; and ventilation done right, because in the Pacific Northwest a quiet, properly-sized fan on a humidity switch is what keeps new grout and paint looking new. Where to save: keep the drain locations, choose standard-size fixtures, and put statement tile on one wall rather than four.
What about the timeline?
Small baths move quickly once work starts: a refresh typically runs one to two weeks on site and a full remodel three to five, the same rhythm as any bathroom since the trades run in sequence, not by the square foot. Our bathroom remodel timeline guide has the week-by-week breakdown, and if you are weighing doing parts yourself, our DIY vs. contractor guide is honest about which pieces are safe to take on and which belong with licensed trades.
Small bath, real value
Hall and guest baths carry outsized weight with buyers — they are the baths guests and appraisers actually see — and updated small baths are among the steadier value-holders in the Snohomish County market (our bathroom value guide covers which upgrades pay). Go Far Construction remodels bathrooms of every size across Lynnwood, Edmonds, Everett, Bothell, and the greater Seattle area, with free itemized estimates so you can see exactly where a small-bath budget goes before you commit.
