Key Features
Smoked Tempered Glass Entrance
An 8mm smoked-glass door adds an unmistakably modern edge – engineered to endure extreme heat and humidity while elevating the sauna’s architectural presence.
40 mm Black Thermowood® Exterior
No thin panels here – only solid 40mm Thermowood®, thermally modified for decades of strength. Finished in a bold matte-black, it insulates better, resists moisture longer and looks worlds apart from mass-produced imitations.
Opposing Bench Seating
Forget cramped corners. Two-tiered Alder benches on each side offers premium comfort – with a spacious upper platform for full-body recline. The face-to-face layout turns each session into a shared, social ritual.
European Excellence
Designed and built in Europe to the highest standards, the ‘Black Cube’ Outdoor Sauna is unapologetically premium – defying the ordinary with craftsmanship you can feel in every detail.
Atmospheric LED Illumination
Soft, integrated LED lighting sets the mood. It’s not just a sauna – it’s an escape, crafted to feel like your private retreat.
Engineered Ventilation
Four precision-cut vents ensure a continuous flow of fresh air, maintaining balance and protecting your sauna’s longevity.
Luxury in the Details
Every detail is designed to elevate your experience — including the Nerostep plastic grid floor mat that keeps your footing comfortable and hygienic.
