Mercer Island bathroom remodeling operates at a consistent specification level that's uncommon even by Eastside standards. The island's home values, design expectations, and client engagement all point toward bathrooms that are genuinely designed — not renovated. Marble slab walls. Steam showers with digital thermostatic controls. Heated radiant floors. Custom furniture-grade cabinetry with hand-selected hardware. Freestanding tubs positioned for lake or Cascade views. Armada Design & Build has been remodeling bathrooms on Mercer Island since 2011, and this is a level of work we execute regularly rather than occasionally.

Local Context

What Mercer Island Bathroom Remodels Look Like

The mid-century modern properties on the island — 1950s and 60s homes on large lots with serious architectural character — present the most interesting bathroom remodel challenges. These homes were designed with spatial intelligence, but their bathrooms reflect the era: small by modern standards, with fixtures and layouts that have nothing to do with the rest of the home's quality. The best mid-century bathroom remodels here preserve the spatial relationships — the light source, the connection to the bedroom, the ceiling height — while completely reconstructing everything material. Natural stone that reads as warm, not cold. Vanity proportions that don't overwhelm the room. Fixtures that feel appropriate to the era without being period pieces.

The 1980s and 90s custom homes that make up a significant portion of the island's housing stock have bathrooms that were specified well for their time — solid granite, oak cabinetry, quality fixtures. But they read as dated now, and the layout conventions of that era (separate tub and shower in a master bath, whether or not both get used) no longer serve how people live. These remodels almost always involve converting the tub/shower separation into a single large walk-in shower with a freestanding soaking tub as a design element rather than daily plumbing.

Newer island construction has contemporary bathrooms that are recent but not thoughtful — the work is refinement: replacing good-quality-but-generic with selections that are actually specific to the home and the client's aesthetic.

Bathroom Types We Remodel

Every Kind of Bathroom, Done Right

Primary Suite Bathrooms

The most involved projects we do on Mercer Island. Custom stone slab work with yard visits, steam showers, heated floors, furniture-grade vanity cabinetry, and design direction that treats the bathroom as a room rather than a service space.

Mid-Century Bathroom Renovations

Sensitive renovations that respect the home's architectural character while completely rebuilding the bathroom's materials and fixtures. Natural stone over porcelain. Wall-mounted fixtures over pedestal sinks. Materials that feel of the period without being period reproductions.

Guest & Secondary Bathrooms

Secondary bathrooms on Mercer Island still receive serious design attention — consistent material language with the primary suite, quality fixtures, and details that match the overall standard of the home.

Powder Rooms

On Mercer Island, a powder room is a design opportunity. Dramatic wallcovering or tile, a statement vessel or undermount sink, a striking fixture selection — we approach these as small-scale design installations rather than functional afterthoughts.

What We Do

Bathroom Remodeling Services on Mercer Island

Natural Stone & Slab Work

Marble, quartzite, and book-matched stone installations. We arrange stone yard visits so you choose your actual slabs — not catalog photos. Slab-to-wall and slab-to-floor installations with minimal grout lines.

Steam Showers

Generator sizing, digital thermostatic controls, proper waterproofing for steam environments, and ceiling pitch to prevent condensation drips. We've installed these systems throughout the island and know the requirements.

Furniture-Grade Cabinetry

Custom vanity cabinets with inset doors, furniture-grade interiors, and hardware selected as a design element. We work with cabinet makers who produce at the level Mercer Island projects require.

Radiant Heated Floors

Electric radiant systems under tile — standard on every primary suite remodel we do on the island. Properly sized thermostats, programmable schedules, and warranties on the heating elements.

Freestanding Tub Installations

Structural floor reinforcement where required, floor-mount or wall-mount filler configurations, and positioning for lake or garden views where the layout allows.

Permitting

Mercer Island falls within King County unincorporated jurisdiction for most properties. Generally efficient for bathroom scope. We prepare and submit permit packages and manage the review process.

Mercer Island Clients Expect Design Engagement — We Deliver It

The clients we work with on Mercer Island bring serious attention to the design process. They've researched materials, they have aesthetic opinions, and they want to understand why each decision is being made — not just approve it. Our design presentations include 3D renderings of the finished space, physical material samples, detailed specification sheets, and the reasoning behind every selection. We don't present a default and ask for approval; we present a direction with the logic behind it and refine collaboratively until it's exactly right.

Construction on Mercer Island primary suite projects typically runs 6–10 weeks depending on scope, custom cabinetry lead times, and stone fabrication schedules. We build the full timeline into the contract from day one.
