Who does what

We design and build the room. A cabinet shop builds the custom millwork to our drawings.

The room sets the cabinetry. Wall blocking, circuits, light positions and the door go in before drywall, so the cabinet layout is drawn first.

Volcano Builders

  • Design, layout drawings and the wardrobe inventory. Permit documents.
  • Wall changes, blocking for every cabinet run and stud anchoring.
  • New circuits and layered lighting. Flooring, drywall, paint and doors.
  • Stone island tops and glass. One schedule and the city inspections.

Cabinet shop

  • Builds and installs the cabinetry, island and paneling to our drawings.
  • Super-Luxury: a top tier Seattle-made system or a bespoke millwork shop, named here once our agreement is signed.

Lighting control integrator (Super-Luxury)

  • Programs lighting scenes. Named here once our agreement is signed.

You

  • One contact at Volcano and one schedule for the room and the cabinetry.

How we priced this

We started from published 2026 cabinet and room costs, then added the room around the cabinetry: lighting, walls, stone and glass. Design fees and city permit fees are listed separately. Basic walk-in suites start above the top California Closets walk-in shown ($33,607). Walk-in closet suites (A) and libraries and built-ins (C) sit below our approved primary bathroom tiers ($65K+ to $225K+) at every level, because neither has plumbing. Top tier millwork has no published wardrobe price, so the Henrybuilt kitchen range below is our top tier reference.

Room requirements for a dressing room

A dressing room is built to published dimensions and code sections. Each one sets a measurement, a circuit or a material on the drawings.

Permits for a dressing room in Seattle, Bellevue and the Eastside

Cabinetry alone often needs no building permit. New wiring and moved walls do. We prepare the drawings and our expediter submits the permit documents. City permit fees are the owner's cost.

  • SeattleCabinets and paneling installed over existing walls and ceilings need no building permit (SRC R105.2 item 2). The minor work exemption stops at $6,000 in any 6 month period, which every tier exceeds. New wiring needs an electrical permit (SDCI). Moving or adding walls needs a building permit; small nonstructural changes can use a subject to field inspection permit (SDCI).
  • BellevueRemoving, moving or adding non-bearing walls uses a BT permit with no plan review, usually issued the same day. A pre-construction meeting with an inspector comes before work starts. Bearing wall changes, or turning unconditioned space into a room, need plan review, about three weeks. Adding or moving circuits needs an electrical permit (City of Bellevue).
  • Kirkland, Mercer Island, Sammamish, Issaquah and unincorporated King CountyThese permit offices use the MyBuildingPermit tip sheet: "A permit is required for work not listed" (TS-00, Jun 2026).
  • Medina, Clyde Hill and IssaquahWashington L&I issues the electrical permits. Building permits in Medina go through the City of Medina Development Services.
  • Bedroom conversionsThe room stops being a sleeping room, so smoke alarm locations around it change (SRC R314.3).
  • Electrical codeWashington moves to the 2026 National Electrical Code for wiring on or after 31 Dec 2026 (WSR 25-23-069).

How a dressing room gets built

  1. Book a consultation.

    Call (206) 666-0412 or use the form below.

  2. Site visit.

    We measure the room, list what it has to hold, and check the walls, the electrical panel and the floor under heavy pieces.

  3. Drawings, selections, then a written, itemized proposal.

    Cabinet layout, lighting, stone and glass are set before anything is ordered.

  4. Build, inspections, then the cabinetry.

    We build the room and set the blocking and wiring. The city inspects each stage. The cabinetry goes in after drywall and paint, and the room is covered by our warranty.

By appointment. Limited start dates.

Google reviews of past Volcano projects

Bar's team completely transformed my outdated Seattle bathroom with their exceptional work. Their communication was excellent, keeping me informed every step of the way. The quality of their workmanship exceeded my expectations, turning my old bathroom into what I wanted. I highly recommend Bar and his team for any remodeling project; they're professional, efficient, and produce outstanding results.

Filip, Seattle, April 2024, Volcano Builders Bellevue Google profile

Bar and his team did an excellent job on our condo bathroom renovation. From the start, Bar was easy to communicate with and quick to respond to all our questions and concerns. We couldn't be happier with the results and highly recommend Volcano Builders to anyone considering a remodel.

Questions about custom walk-in closets and dressing rooms

How much does a custom closet cost?

A system closet costs $1,080 to $3,229 nationally, about $2,136 on average (HomeAdvisor, June 2026). California Closets shows walk-in systems from $5,817 to $33,607 as shown (October 2026). A dressing room adds lighting, stone, glass, room work and the permit. Our walk-in closet suites start at $40K+ and dressing rooms at $70K+.

How big and how wide should a walk-in closet be?

Plan at least 6 x 10 ft, the average size (California Closets, March 2026). Allow 6 ft between walls for rods on both sides: two 24 in hanging zones and a 24 in walkway. California Closets calls 4 x 4 ft the minimum viable size. CRD calls 12 x 14 ft optimal for a large closet, with room for an island.

How much space does a closet island need?

Leave 36 in clear on all sides of the island (California Closets, March 2026). CRD Design Build says an island layout needs a room about 13 ft deep. With 24 in of hanging on both walls, 13 ft leaves room for an island about 36 in deep.

How do you turn a bedroom into a dressing room?

Remove or keep the closet wall, then add cabinetry, an island, lighting and a door. In Bellevue, moving a non-bearing wall uses a BT permit, usually issued the same day, with a pre-construction meeting. The room stops being a sleeping room, so smoke alarm locations around it change (SRC R314.3).

Do I need a permit for a walk-in closet in Seattle?

Not for cabinets alone. Cabinets installed over existing walls and ceilings need no building permit (SRC R105.2). New wiring needs an electrical permit, and moving walls needs a building permit. For closet design in Seattle that moves walls, we prepare the drawings and our expediter submits the permit documents.

How much do built-in bookshelves cost?

Built-in bookshelves average $300 to $850 per linear foot installed, custom $400 to $1,000+, and hardwood $500 to $1,200 (HomeGuide 2026 cost guide). A hidden bookcase door adds $2,000 to $8,000 (HomeAdvisor, June 2026). Our libraries and built-ins start at $40K+.

What lighting is best for a walk-in closet?

Layered LED: strips on the shelf fronts, light in recesses deeper than 24 in, and uplight under hanging clothes (AD PRO, February 2026). Washington requires every permanent interior fixture to be high efficacy and on a dimmer, occupancy sensor or built-in control (WSEC R404.1, R404.2).

What is a dressing room?

A dressing room is a walk-in closet finished as a room: cabinetry on every wall, an island, seating, a mirror or vanity, and its own lighting. Designers in 2026 add vanities, laundry, steamers and safes (AD PRO, February 2026). We plan them for converted bedrooms, bonus rooms and new primary suites.

How long does a custom closet take to install?

A system closet installs in one day (California Closets, September 2026). A walk-in takes 2 to 3 days, longer when walls move or lights are wired (HomeAdvisor, June 2026). A dressing room adds design, permit and cabinet fabrication time. A top tier Seattle maker plans 8 to 10 months from the start of design for short projects (Henrybuilt FAQ).
