ThermaSol Nordic Misty Outdoor Sauna Cabin

Your Own Corner of the North

There's a version of the end of the day where you don't reach for your phone — you reach for the door of a sauna, step into the warmth, and let the cold and the noise stay outside. The Nordic Misty brings that to your own backyard.

From the outside it reads as quiet Scandinavian architecture: a dark, heat-treated spruce exterior, weathered to resist sun and time, sitting low and handsome in the garden. Step through the lockable, full-length tinted glass door and the mood shifts — a warm interior of heat-treated aspen, a panoramic tinted glass wall that pulls in the daylight and the view while keeping you completely private, and soft recessed LED light glowing from beneath the benches and above the backrest. The Harvia heater builds a deep, enveloping warmth, and the bench is yours for as long as you want it.

It arrives fully assembled and pre-wired — a turnkey cabin set on your prepared foundation, ready the day it lands. And it grows with you: the Nordic Misty connects to other Misty modules — a lounge, a changing room, a covered terrace — so you can start with the sauna and build a whole outdoor wellness retreat over time, exactly to your space.

Choose your size — a 2–3 person Small or a 4–5 person Medium — and your heat: a 9kW Harvia Virta electric, or a traditional Harvia wood-burning stove for the full Nordic ritual.

Some things you add to a home are features. This is a place — somewhere, just outside the back door, that's entirely your own.

Safety & Good to Know Sauna use isn't right for everyone. Consult your physician before use, especially if you are pregnant or have a heart condition, high or low blood pressure, or any cardiovascular or other medical concern. Begin with shorter, lower-heat sessions, hydrate, avoid alcohol before use, limit sessions (don't exceed ~30 minutes), supervise children, and keep the door locked when not in use. Use only clean water on the stones.

What sizes does the Nordic Misty come in? Two: a Small (91" x 60", 2-3 people) and a Medium (91" x 87", 4-5 people).

Can I choose the heater? Yes - a 9kW Harvia Virta electric heater, or a traditional Harvia wood-burning stove for a classic Nordic experience.

Can people see inside? The full-length tinted glass wall brings in natural light and views while maintaining privacy during daytime use, and the door is lockable.

Is it really modular? Yes - it connects via screw connections to other Nordic Misty modules (lounge, changing room, covered terrace), so you can start with the sauna and expand your outdoor space over time.

How is it delivered? Fully assembled and turnkey via flatbed trailer (~12-13 weeks). A forklift or crane is required for offloading and placement; you're notified about two weeks ahead to prepare the site.

What foundation does it need? A firm, level surface with slight drainage runoff - concrete slabs, decking, pavers, or compacted gravel. It should never sit directly on the ground, and needs airflow underneath. The cabin has its own drainage built in.

What electrical setup does the electric version need? The 9kW Harvia Virta requires a 5x2.5mm cable and 3x16A fuses, hardwired by a licensed electrician.

How long does it take to heat up? About an hour to reach a bathing temperature of roughly 149-176F, depending on outdoor conditions.

What's the warranty? A 2-year warranty on materials and manufacturing (6 months for commercial use); the Harvia heater carries its own 1-year guarantee.
