Steam-Ready Interior Builds
Interiors are planned for steam-friendly use with the right wood, hardware, and layout so surfaces, seams, and joints handle humidity while still looking refined.

FAQ — Custom Saunas in Vancouver, WA
Do you build the exterior structure?
No. Only the sauna interior is built. Any exterior framing, roofing, or foundation work should be completed and weather-tight before interior construction starts.
How much space do I need for a sauna?
Most residential saunas begin around 4′ x 6′, but the layout can be adjusted larger or more compact depending on your room and bench goals
Do you handle electrical or plumbing?
The interior is prepped for heater, lighting, and any needed penetrations, while a licensed electrician or plumber completes all connections and final hook-ups.
Can you finish an outdoor sauna interior?
Yes. The full interior can be completed inside your existing outdoor sauna shell once the structure is framed, enclosed, and ready for finish work.
Can you upgrade a prefab sauna?
Yes. Standard prefab interiors can be improved with custom benches, new wall and ceiling boards, and upgraded trim for a more solid, built-in feel.
How long does the interior build take?
Most sauna interiors are wrapped up within a few weeks once on-site work begins, with timing based on size, complexity, and site readiness.
Do saunas need ventilation?
Yes. Fresh-air and exhaust venting are planned with your heater type and room layout in mind to support comfort and proper air movement.
Do you serve areas beyond Battle Ground?
Yes. Projects are completed in Battle Ground, nearby north Clark County communities, and the greater Portland–Vancouver metro area.
