Bathroom Remodel Cost in Bellevue & King County (2026 Guide)

Published July 11, 2026 · By TJ Construction · Bellevue & King County, WA

Planning a bathroom remodel in Bellevue or elsewhere in King County? The first thing every homeowner wants to know is how much it will cost. Bathrooms are one of the most popular remodels in the Eastside market, and prices vary widely depending on the size of the room and the finishes you choose. Here's a clear 2026 breakdown to help you budget.

Quick answer: In 2026, most bathroom remodels in the Bellevue & King County area cost between $12,000 and $35,000. A small guest or half-bath refresh can start around $8,000, while a large primary (master) suite with premium finishes can run $45,000 or more. Your final price depends on the size of the bathroom, the materials you select, and whether the plumbing layout changes.

Bathroom Remodel Cost by Project Type

Half-bath / powder room — $8,000 to $15,000

A small room with just a toilet and sink. Updating the vanity, toilet, fixtures, flooring, lighting, and paint gives a big visual upgrade without moving plumbing.

Standard full bathroom — $15,000 to $30,000

A hall or guest bath with tub or shower, vanity, and toilet. This is the most common range for Bellevue-area homeowners and usually includes new tile, a vanity, a tub-to-shower conversion or new surround, fixtures, and flooring.

Primary / master suite bath — $30,000 to $45,000+

A larger remodel with a walk-in shower, freestanding tub, double vanity, custom tile, heated floors, and premium finishes. Moving walls or relocating plumbing pushes cost toward the top of the range.

What Drives the Cost of a Bellevue Bathroom Remodel?

Layout & plumbing changes — moving the toilet, tub, or shower drain is the single biggest cost driver.
Tile & waterproofing — custom tile work and proper waterproofing behind showers add labor and material cost, but protect your home long-term.
Vanity & countertops — stock vs. custom cabinetry and quartz or stone tops vary widely.
Shower & tub choices — a prefab surround is far cheaper than a custom tiled walk-in shower or freestanding soaking tub.
Permits — plumbing and electrical changes in King County typically require permits, which a licensed contractor pulls and manages for you.
Labor — Eastside labor rates run higher than the national average, which is reflected in local pricing.

How to Keep Your Bathroom Remodel On Budget

Keep the existing plumbing layout if it works — relocating fixtures is expensive.
Choose mid-range tile and fixtures that look high-end for less.
Get a detailed written estimate before demolition begins (we provide these free).
Invest in quality waterproofing and ventilation — the Pacific NW's damp climate makes both essential.
Set aside 10–15% for surprises, especially hidden water damage in older Bellevue homes.

Frequently Asked Questions

How long does a bathroom remodel take in Bellevue?
Most bathroom remodels take 2 to 4 weeks once work begins, depending on the scope, tile work, and material lead times.

Do I need a permit for a bathroom remodel in King County?
Simple cosmetic updates usually don't, but moving plumbing, adding electrical, or altering the layout typically requires a permit. A licensed general contractor handles permitting for you.

Is a tub-to-shower conversion worth it?
For many homeowners, yes — a walk-in shower adds accessibility and a modern look. If it's your only tub, keeping one tub in the home is usually smart for resale.

Yes — bathrooms are one of the highest-return remodels, and updated baths are especially valuable in the competitive Bellevue & King County market.
