Minimalist Design. Maximum Presence.

With its sleek all-black Thermowood exterior, sharp clean lines, and smoked tempered glass, this sauna represents true contemporary outdoor luxury without compromise.
Designed specifically for outdoor environments where aesthetics matter as much as performance, the Black Cube integrates seamlessly into compact yards and patios while comfortably accommodating up to four adults inside.
The interior features natural wood finishes, layered alder benches, and dimmable LED lighting, creating a calming atmosphere that soothes both body and mind.
Build It. Enjoy It. Make It Yours.
