Golden Designs Karlstad 6-Person Indoor/Outdoor Hybrid Full-Spectrum Sauna
Authorized Dealer
Full manufacturer warranty
Two full heat systems in one 6-person cabin. The Karlstad pairs a Harvia 8kW stove and stones for real high-heat steam with a 3500W full-spectrum infrared array, 13 emitters in total, so daily gentle warmth and the weekend loyly ritual live under the same cedar roof. At 79.2" wide and 84.7" deep it is one of the larger indoor/outdoor hybrids in the line, with an all-weather exterior that lets you site it in a finished basement now and move it to the patio later.
Why one cabin, both heat modes
On infrared days, four carbon PureTech emitters and nine near-infrared emitters warm your body directly in a lower, easy-to-sit range, comfortable for a longer daily session. When you want the classic experience, fire the Harvia stove, ladle water over the stones, and the room climbs into steam territory. The full operating window runs 118 to 190°F across both modes. Both the stove and the full-spectrum system draw from a single 240V, 40A dedicated circuit, so a licensed electrician sets up the hookup once.
What a daily session looks like
- Weekday unwind: Low, gentle infrared warmth after work or a long day on your feet
- Post-workout recovery: Steady heat for sore muscles and a proper sweat
- Weekend loyly: Fire the Harvia, pour water on the stones, and share the high-heat ritual with a full group
Built for real life
- Best for: Households that want daily infrared and authentic Finnish steam in one large 5+ person cabin, indoors or out
- Included comforts: Bronze privacy tempered glass door with stainless hinge and handle, oversize interior chromotherapy lighting, lit backrest, exterior accent lighting, interior LED control panel with FM and Bluetooth, built-in speakers, plus sandglass, bucket, and scoop
Where it sits in the line: If six seats is more room than you need, the Golden Designs Carinthia 3-Person Outdoor Hybrid steps the same infrared-plus-stove concept down to a smaller footprint.

Common questions about this sauna
Will this sauna fit through my doorway and into my room?
It does not arrive as one finished cabin. It ships flat and assembles on site, so what has to clear your doorways and stairs are the individual panels, not the full assembled cabin. Set up, it stands 79.2 by 84.7 by 88.3 inches (width by depth by height).
Measure your narrowest doorway, hallway turn, and stairwell, then use our Will It Fit tool to place it in your room to the inch. If an entry looks tight, send us the measurements and we will confirm the fit before you order.
What outlet or wiring does it need?
It needs 240V / 40A dedicated circuit (stove and full-spectrum).
Because it runs on 240V, have a licensed electrician put in the dedicated circuit before your delivery date. That is standard for a stove heated sauna and is the only trade work involved.
Is assembly difficult, and how long does it take?
2 people, 4 to 6 hours. Tongue-and-groove assembly; licensed electrician required for stove hookup.
The sections arrive pre built and ready to join, so you are connecting finished panels rather than building from raw lumber. No specialist trade is needed beyond any electrical hookup noted above.
Is this a low EMF sauna?
Yes. Golden Designs rates this cabin as Near-Zero EMF.
EMF is the low frequency field that surrounds any electric heater. This model uses carbon panels that spread warmth across a wide surface instead of concentrating it, which is how it holds a Near-Zero EMF rating.
Can it go outside?
This model is built for indoor use. Its construction is not rated for open weather exposure, so plan for a garage, basement, spare room, or a fully covered porch rather than an open yard.
If you want a sauna for an uncovered outdoor spot, ask us about our outdoor rated cabins.
How is it delivered, and how long does it take?
It ships free by curbside freight. Free curbside freight delivery to your driveway. Typical lead time 10 to 20 business days. AK, HI, and Canada quoted separately.
Your carrier calls ahead to schedule a drop off window and leaves it at the end of your driveway, so plan to have a hand available to move it inside.
Are you an authorized dealer, and what warranty comes with it?
Yes. PureHeat is an authorized Golden Designs dealer, so this is a genuine unit that carries its full Golden Designs factory warranty (5 years on electronics and heating, 1 year on the traditional stove), honored directly by the manufacturer. Register it within 60 days of delivery at the manufacturer registration form to activate coverage.
That matters on a purchase this size. Units from unauthorized gray market sellers often arrive with the factory warranty voided, which can leave you without support if a part ever fails.
