The Black Cube Comfort
The Comfort is our most spacious Black Cube, designed for those who want room to stretch out and share the experience with family and friends. With generous face-to-face benches seating 6-8 people, it's perfect for social gatherings or simply enjoying more personal space.
Unlike our kit models, the Comfort lets you customise your build – choose your preferred heater, control panel, lighting, and glass options. Each sauna is made to order in Estonia with a 3-4 week lead time.
HUUM FLOW MINI Wood-Burning
For the ultimate traditional sauna experience, the HUUM FLOW MINI brings the crackle of real fire and the ritual of tending the flames. There's something deeply satisfying about heating your sauna the old-fashioned way.
The FLOW MINI produces exceptional löyly – soft, enveloping steam that sauna purists love. The integrated air tunnel design ensures efficient combustion while the large stone capacity holds heat beautifully between sessions.
Wood-Burning Package Includes:
HUUM FLOW MINI stove, protective bedding, floor protective plate, 105kg sauna stones, and complete chimney set. No electricity required for the heater – perfect for off-grid locations.
