Outdoor Barrel Sauna 340 cm with Electric Stove
Experience the authentic Nordic sauna in your own garden.

Why Choose Our Saunas?
Premium Wood Quality
Crafted from Scandinavian spruce, kiln-dried to only 14% moisture content. This ensures maximum stability, protects against cracks and warping, and extends the sauna’s lifetime to more than 15 years.
What truly sets our saunas apart is the 44 mm wall thickness — nearly double that of most competitors (typically 28–34 mm). This extra thickness not only enhances durability but also significantly improves heat retention and structural strength, giving the sauna a solid, premium feel that lasts.
Complete heating system included
The sauna comes with a Harvia Cilindro PC90 electric stove (9 kW). The stainless steel open basket design lets you enjoy soft, gentle steam when water is poured on the sides or more intense steam when poured on top. The built-in thermostat and timer provide precise temperature control, while the powerful heating elements warm the cabin to 80 °C in ~30–40 minutes. Everything you need for installation is included — only the final electrical connection must be done.
Alder benches – natural comfort
Inside you’ll find benches made of alder. Unlike spruce or pine, alder does not overheat, so it remains comfortable to sit or lie on even at high temperatures. The single-level layout provides a spacious and ergonomic seating area — ideal for relaxing in comfort, even during longer sauna sessions. Perfect for families with children or sensitive skin.
Assemble in one day – move it whenever you need
Designed for DIY assembly — two people can put it together in just 13–14 hours using standard tools. No foundation, heavy machinery, or special skills required. Thanks to its lightweight yet durable construction, the sauna can be relocated on your property or even transported to a new home in the future.
Traditional Barrel Design – compact and efficient
The rounded barrel shape is not only iconic but also highly functional. With minimal unused air space, it heats up quickly and retains warmth longer, saving both time and energy. Its timeless look blends naturally into any garden, adding a touch of authentic Nordic charm.

The big barrel impresses guests. We went in with five or six people. Timber is dry, we found no resin. We additionally added a small LED lighting kit; the warm light creates a calm mood. Press a button and you are set.
Everything matches the description. Nothing to complain about. Just buy it and assemble it 😉 The Harvia Cilindro 9kW heats up to 70–80°C in about an hour.
Great sauna! For me, assembling it was pretty intuitive – you do need to do a bit of sanding, but that’s normal with wood. Putting it together and applying the protective coat took me three afternoons – you can easily do about 90% of the work on your own. The quality is really solid, thick beams, and the stove heats the sauna in just 30–40 minutes, so super fast. Important: make sure to burn in the stove before using it for the first time.
