Garden Sauna QUADRO 340 cm with Electric Stove
Bring the authentic Scandinavian spa experience to your home.
This extra-large sauna offers a 220 cm width, 340 cm length (with entry area and terrace), and a 240 cm full standing height— spacious enough for 4–6 people. With durable Swedish spruce construction, comfortable alder benches, and easy assembly, it’s designed to provide many years of relaxation, health, and family enjoyment.
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 ~40 minutes. Everything you need for installation is included — only the final electrical connection must be done.
Two-level alder benches – ergonomic and cozy
Inside you’ll find two-level L-shaped benches made of alder. Unlike spruce or pine, alder does not overheat, so it’s comfortable to sit or lie on even at high temperatures. The double-level arrangement allows everyone to choose their preferred intensity — hotter on the upper bench, milder on the lower. 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 13–15 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.
Modern QUADRO design – spacious and stylish
Unlike round barrel saunas, the QUADRO shape offers straight walls and full standing height across the entire cabin. This gives more usable space, longer bench runs, and greater comfort for taller users. Its sleek, modern form blends beautifully into any garden or backyard. A timeless design that looks as good as it feels.

The sauna is really awesome! Everything was delivered right to the house, perfectly packed, and every part is carefully made and fits together so well that assembling it was pure pleasure. It heats up quickly and keeps the heat for a long time. A beautiful addition to the garden!
For such a size the assembly is surprisingly simple. Controller is intuitive and remembers modes. Back tension eases after a session. Thick walls give even heat and pleasant steam.
Putting it together was easier than I expected. Everything fits perfectly, and like the description says, one person is enough to assemble it.
We bought it for gatherings. Six people fit fine without crowding. Holds 80 °C steadily. Press the button and it warms without extra steps. The wood is quality and looks substantial.
100% as described. High-quality materials. Very clear instructions for self-assembly.
