Garden Sauna QUADRO 240 cm with Electric Stove
Bring the Scandinavian spa experience home.
This sauna offers a 220 cm width, 240 cm length (with a 0.4 m terrace), and a 220 cm full standing height — compact for most gardens, yet roomy enough for 4–6 people. Strong, comfortable, and easy to assemble, it’s built to last for years of relaxation.
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.
Two-level alder benches – ergonomic and cozy
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 12–13 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 assembled. I waited a bit before putting it together, so some boards warped slightly, but it was still manageable.
Excellent build, beautiful sauna, and reasonably priced! I honestly recommend it. On top of that, the customer service is professional, helpful, and friendly! The product’s quality fully matches the price. No major issues at all. Really happy with the money spent.
One picture in the manual did not match, we lost about 15 minutes figuring it out. Otherwise parts are well aligned. The electric setup is a joy, press the button and done. Sleep improved and shoulder tension eased. Gardj looks like the best value for money.
Hooked up the same day and we were steaming by evening. No condensation issues; ventilation does its job. Maintenance is minimal, just air it out and wipe. Wood is top quality and Gardj is, in my view, the best deal for the money.
Courier called ahead and unloaded carefully. Packaging is solid, everything pristine. A couple of spare screws came in handy. Assembly in 2 days without rush. With electric heat there is minimal effort and minimal maintenance.
Fresh spruce scent in the first days, very nice. Clean hookup, everything standard. Great that you simply switch it on and wait for heat. The wood is very high quality with no cracks. Cozy inside, a good place to sit quietly and reset.
The cable on site was a bit short so we bought an extension. Assembly itself was flawless, gaps are even and the door seals tight. Nice that you just turn it on and you are ready within an hour. The wood is quality and the wall thickness inspires confidence.
The heater runs quietly. Bronze-tinted door glass looks great in the evening. Ventilation keeps the steam soft, never stuffy. I wipe benches once a month and it looks like new. The wood really is top quality.
We use it for recovery after runs. Twenty to thirty minutes at 70–75 °C relaxes the muscles. Press the button and it warms fast. Wood is smooth, no resin, and the thick walls hold heat confidently.
We assembled it as a pair after work, one long evening plus the next day. The manual links to a video which speeds things up. Electric heater means you just press a button and that is it, no fire starting. Reaches about 80 °C in roughly an hour, steam feels even. Wood quality is top notch and the walls feel properly thick.
Kids ride bikes while we steam, perfect weekends. The door glass does not haze. We wipe after sessions and it looks new. Thick walls keep the heat for a long time.
Family format: two adults and an 8 year old fit without fuss. Installed on a slab, hookup took a bit longer than assembly. Controller is intuitive, we keep 70 °C. Super convenient that nothing needs lighting. Timber is dry and straight, the walls are thicker than we expected.
