Bathroom Remodeling in Mercer Island, WA

For Mercer Island homes valued around $1,800,000, bathroom remodels range from $54,000 for a cosmetic refresh (new vanity, fixtures, paint, lighting) to $162,000 for a full spa-style renovation with custom tile, frameless glass shower, heated floors, and premium fixtures. The average project in Mercer Island comes in around $108,000. Tile selection is the biggest cost variable — porcelain at $7-14/sqft vs. marble at $18-35/sqft can swing the total by $3,000-$8,000. We'll walk through all the options during your free consultation.

A cosmetic refresh takes 5-8 days. A mid-range remodel with new tile and fixtures runs 2-3 weeks. A full gut renovation in Mercer Island takes 4-6 weeks. Permits from King County add 2-4 weeks before construction if your project involves plumbing or electrical work. Tile is the biggest time factor — a fully tiled shower with floor-to-ceiling tile needs 3-5 days just for the tile setter, plus cure time. In Mercer Island's 45-year-old homes, we sometimes find plumbing or waterproofing issues during demo that add a couple of days.

The City of Mercer Island Development Services Group handles all residential building permits. The island has strict building codes including tree protection ordinances that may affect project logistics. Permit review for residential kitchen and bathroom projects typically takes 3-5 weeks. All work within the shoreline zone requires additional environmental review. In practical terms: a tub-to-shower conversion requires a plumbing permit. Adding or moving electrical outlets or circuits requires an electrical permit. Structural changes need a building permit. Cosmetic updates (new vanity, paint, accessories) don't need permits. We handle all the paperwork and inspections as part of our standard service — it's included in your quote.

The #1 request from Mercer Island homeowners is converting an old tub-shower combo to a walk-in shower with frameless glass — we do this project more than any other. Heated tile floors are extremely popular in our PNW climate (they cost $600-$1,600 and add about $30/year to your electric bill). Other common requests: floating vanities, large-format porcelain tile that mimics marble, proper exhaust fans with humidity sensors, and built-in shower niches. In the mid-century modern homes common to Mercer Island, improving ventilation is especially important given our 9 months of damp weather.
