The Saunum AirCube 3 Outdoor Cabin Sauna is stunning. It’s easy to be impressed with a sauna like this when the craftsmanship and design are so well thought out. The full glass front wall and refined woodwork showcase a beautifully modern and inviting interior.
We love how the AirCube 3 blends luxury and functionality. The tempered glass front wall adds a contemporary touch, while the Thermo-Spruce exterior ensures durability against outdoor elements. Step inside and you’re met with a furniture-grade Thermo-Aspen interior, paired with upper and lower L-shaped benches that give you plenty of space to stretch out and relax.
This sauna doesn’t just look great—it creates an atmosphere. Mood-setting LED lighting, both inside and outside, gives you a warm, relaxing glow, while built-in Bluetooth speakers let you set the soundtrack to your session. The small porch on the front is a perfect spot to cool off between sessions, making the AirCube 3 a complete backyard retreat.
With a long list of enticing features on a sauna that is so beautiful like this one, you might wonder why it’s only number 4. This is because the health features and the design efficiency are lacking.
The manufacturers made this sauna so beautiful, but forgot some of the most important aspects of sauna design. Glass transfers heat, even though it's relatively slow compared to other materials. But think about your morning coffee for a second. Would you ever put your coffee in a glass cup? Relative to wood, glass transfers heat much more quickly, which means that heat escapes more easily, the more glass there is in a sauna, and this sauna has an entire side made of glass. On top of that, the glass doesn’t support a vacuum seal, so all of the little openings created by doors and windows on this sauna allow heat to escape, which makes this sauna inefficient. This sauna also does not come with a sauna stove and requires you to buy a separate stove.
