6-Person Barn Hybrid (Full Spectrum IR + Traditional) Outdoor Sauna
A larger barn sauna built for shared rituals, easy hosting, and nights that stretch on.
The Kaskinen brings a fuller, more generous feel to the backyard—spacious, warm, and made for families, guests, and the kind of evenings when nobody is in a rush to head back inside.
Every Golden Designs hybrid sauna ships with two heating systems: a Harvia Wall Series traditional stove and a full spectrum PureTech infrared array. The same brand trusted by commercial spas and sauna builders across Scandinavia for over 70 years, paired with near zero EMF infrared technology.
The Wall SW80 is an 8kW wall-mounted unit built from stainless steel with direct rock-to-element contact for fast, even heat distribution. Pour water over the stones for a classic steam experience at 170-185°F. Switch to the full spectrum infrared emitters for a lower operating range of 118-132°F. Or run both.
Every component, specified and selected with intent.

The Kaskinen has been a big upgrade for our backyard. It fits the family with room to spare, and the barn style makes it feel more like a small cabin than a box. Having both infrared and traditional heat options is what made the higher price feel worth it for us.
