The Karlstad
The Karlstad is a six-person sauna for a full house. Its room is 75 by 67 inches — room for the whole family or a group of friends — and its all-weather exterior lets it anchor the backyard, though it can also live indoors.
Two kinds of warmth share the room, chosen with a single switch. The 8 kW Harvia stove heats the stones to 170–185°F for the steam and ritual of a classic Finnish sauna. The full-spectrum infrared — four PureTech™ Near Zero EMF carbon panels and nine near-infrared elements — warms you directly at a gentler 118–132°F. They run one at a time, so a lively evening of steam with friends and a quiet infrared session after work both have a home here.
Inside, it's natural Canadian red cedar all around. A soft light glows behind the backrest, the oversize chromotherapy light offers any color or a red setting, and your music plays over Bluetooth through the built-in speakers. Through the clear glass door you can watch the evening settle over the yard.
Care is simple: plain water and a soft cloth inside, the exterior finish refreshed over the years, a level concrete pad or wood deck underneath, and one 240V circuit hardwired by a licensed electrician.

Where it can go
Where it can go

- The whole floor must sit completely level and well supported — a concrete pad or a wood deck. On bare ground, use concrete blocks or a similar base so the sauna doesn't settle.
- Keep the ventilation vent clear.
Power
Power
- One dedicated 240V / 40A circuit powers both the stove and the infrared.
