Infrared-Ready Sauna Rooms
Planning an infrared system? We frame and finish the interior shell, then prepare clear locations for your infrared panels, controls, and access points so your installer can complete the setup.
Steam-Ready Interior Builds
For steam-focused installs, we use appropriate materials, slopes, and layout decisions that support steam performance while keeping the interior clean and minimal.

Sauna interiors for small fitness rooms, boutique gyms, and spa-style properties that need durable seating, straightforward maintenance, and a consistent finish.

FAQ — Custom Saunas in Dunthorpe, OR
Do you build the exterior structure?
No. Our work is focused on the interior only. Any exterior framing, foundation, roofing, or siding should be finished before the sauna interior build begins.
How much space do I need for a sauna?
Many sauna layouts start around 4′ x 6′, but the exact size depends on how many people you want to seat and the room you have available. We’ll review your space and propose a layout that fits.
Do you handle electrical or plumbing?
We prepare the interior surfaces and leave proper access points. A licensed electrician or plumber handles all wiring, breakers, lighting hookups, and any plumbing connections.
Can you finish an outdoor sauna interior?
Yes. If you have an outdoor sauna shell in Dunthorpe or nearby, we can complete the interior with walls, ceilings, benches, and trim.
Can you upgrade a prefab sauna?
Yes. We can remove basic benches and wall panels and replace them with sturdier, custom-built components for a more substantial look and feel.
How long does the interior build take?
Most interiors are wrapped up within a few weeks once materials, layout, and schedule are confirmed, depending on project size and complexity.
Do saunas need ventilation?
Yes. Proper venting helps manage heat and fresh air. We plan vent locations around your heater style and overall room design.
Do you work outside Dunthorpe?
Yes. We serve Dunthorpe, surrounding South Portland neighborhoods, Lake Oswego, and nearby communities along the Willamette River corridor.
