Bring the authentic sauna ritual to your garden with the Thermo Wood Barrel Sauna with Window — Regular with Changing Room (4–6 Person). This is the classic barrel silhouette, upgraded for year-round outdoor use, with a dedicated changing room so you can step out of the weather, store your essentials, and keep the sauna space feeling calm and uncluttered.
The barrel shape isn’t just about looks — it’s engineered to deliver even, consistent heat and warm up efficiently. The structure is built from 40mm Nordic thermo-treated spruce, chosen for its stability outdoors and its ability to handle moisture and temperature changes. The thermo treatment is chemical-free and designed to improve durability, helping the sauna stay solid and good-looking through the seasons.
A premium finish runs through the details. You get a tempered glass sauna door and a windowed design that brings in natural light and makes the interior feel more open while you unwind. Inside, the seating is set up for comfortable shared sessions, with aspen benches in the sauna room and additional benching in the changing area, so it works just as well for quiet solo resets as it does for social sauna nights.
In terms of footprint, this model measures 2975mm (L) × 2290mm (W) × 2400mm (H) with a 2250mm diameter, and a sauna room volume of 5.5m³. The main benching is 1635mm × 567mm, with 788mm between opposing benches, and the changing room benching is 1025mm × 567mm. Gross weight with packaging is 880kg, and the timber structure is covered by a 2-year manufacturer’s warranty.
You can choose the setup that suits how you like to sauna. It’s available as a cabin-only option, or you can pair it with an electric heater package (including stones) for convenience and easy control, or a wood-burning heater kit for a more traditional experience. If you want to elevate the atmosphere further, a compatible warm-white lighting kit is available as an add-on.
Delivery is designed to be practical: it arrives flat-packed in a DIY box format, making it easier to transport into position than a fully assembled unit, and it’s intended for straightforward self-assembly if you’re comfortable with basic construction tasks. For longevity outdoors, it’s also worth planning on a suitable exterior wood finish and interior paraffin oil treatment to keep the timber looking its best over time.
One important note for outdoor placement: the door does not have a lock by design (a safety feature), and in very strong winds it can blow open, so it’s smart to position the sauna with shelter in mind or secure the door area during stormy weather.
