Golden Designs Osla 6-Person Traditional Sauna — Canadian Red Cedar

Genuine Finnish-Style Heat

The 8kW traditional stove is built to deliver dry sauna heat in the 170°F–190°F range with a maximum near 195°F. Pour water over the heated stones and you get löyly — the humid burst of steam that defines a real traditional sauna. This is not an infrared cabin operating at 130°F. It's the classic Finnish heat profile that most of the world means when they say the word sauna.

Room For Six, Comfortably

A 6-person capacity in a modular kit is unusually generous. Interior dimensions of 74" × 67" × 78" give upper and lower bench users real space for their legs, their arms, and the person next to them. It's a fit for extended families, couples who host, adult-child recovery sessions, and anyone who has felt cramped in a 4-person cabin.

A Complete Package

The Osla arrives with the pieces that most kits leave you to buy separately: the stove and sauna stones, the LED control panel with FM radio and Bluetooth, the built-in speakers, the ceiling galaxy-star color therapy lighting, backrest accent lighting, a reading lamp, plus a bucket, ladle, sand timer, thermometer, and hygrometer. Uncrate it, assemble it, wire it, and it's ready to run.

Canadian Red Cedar Interior

Cedar is the traditional bench-and-wall wood for good reason. It resists warping through repeated heat and humidity cycles, stays cool enough to sit on comfortably at 190°F, releases a soft warm aroma the moment it heats up, and ages into a deep patina over years of use. Pacific Premium Clear Cedar on the exterior gives you a cleaner, more architectural finish for the room-facing side.

Indoor or Covered Outdoor

The Osla installs indoors — home gyms, dedicated wellness rooms, basement additions, guest suites — or under a covered outdoor structure that protects the panels from direct rain, snow, and sun. Golden Designs' documentation specifies covered exterior use only; leaving the Osla exposed to open weather voids the wood-structure warranty. If you're planning a covered patio installation, we can walk through what qualifies.

Built-In Lighting And Audio

The interior LED control panel handles the temperature, the FM radio, and a Bluetooth pairing that streams from any phone to the built-in performance speakers. The galaxy-star ceiling lighting and dimmable backrest accents let you turn a bright morning session into a quiet, low-lit evening one without changing anything else.

Manufacturer Documentation

Golden Designs Osla installation and owner's manual (PDF, 3.2 MB)

The manual covers step-by-step assembly, electrical hookup, ventilation, first-fire seasoning, and routine maintenance. Golden Designs also ships printed installation and warranty documentation inside the crate.

Assembly Overview

The Osla is a modular kit. Interlocking wall and ceiling panels connect on-site with the included hardware, so you skip framing, drywall, and finish carpentry entirely. Two adults can complete the mechanical assembly in a full day.

Before Delivery — Prepare The Space

• Confirm a level, structurally sound floor pad (concrete, tile, or engineered flooring rated for the load)
• Confirm exterior clearances for ventilation and future service access
• Have a licensed electrician run both circuits to the installation location before the sauna arrives
• For covered outdoor installations, confirm your roof structure fully shelters the sauna from rain, snow, and direct sun

Assembly Sequence

• Two or more adults required for panel handling
• Modular panels lock into a floor track and secure with included hardware
• Ceiling panels install after walls are set and squared
• Bench seating, control panel, lighting, and heater install after the shell is complete
• Final electrical connection is performed by your licensed electrician

If you'd prefer professional installation, we're happy to share contact information for independent sauna assemblers in many U.S. markets. You'd work directly with the assembler and pay them directly — no NW Immersion markup or middleman fee.

Delivery Access — Please Read Before Ordering

We can usually accommodate difficult locations — we just need to plan ahead.

Receiving Your Shipment

Golden Designs Manufacturer Warranty

Golden Designs, Inc. warranties the Osla against defects in materials and workmanship from the original date of purchase, when the sauna is used in accordance with the installation and operating instructions and kept in a covered, protected location.

• Wood structure and panels: 5 years
• Heater elements and stones: covered per Golden Designs' current warranty schedule
• LED control panel, harnesses, and interior lighting: covered per Golden Designs' current warranty schedule
• Manufacturer warranty applies to the original purchaser at the original installation site only

Important: The Osla is warranted for indoor use or covered exterior use with a waterproof roof. Placing the sauna in an uncovered outdoor location, or exposing it to direct rain, snow, sun, or extreme temperature swings, voids the wood-structure warranty. Modifications to the sauna or its components also void the manufacturer warranty.

Beyond the manufacturer terms, we offer a flat one-year support commitment on every sauna we ship: we take responsibility for helping you resolve issues in year one, whether that means walking the electrician through a wiring question, coordinating a replacement panel from Golden Designs, or troubleshooting a control panel over the phone.

Contact support at support@nwimmersion.com or 360-360-6968. Full manufacturer warranty documentation ships with every sauna.
