The Monolith 6 is the flagship — the cube we build when the brief is "make it look like it was always meant to be there."
Who it's for
The design-led buyer finishing a garden, pool house, or rooftop. Where the sauna needs to read as architecture, not equipment. Seats four to six; sized for a gathering, not just a session.
What sets it apart
- Full-height glass facade. A floor-to-roof tempered glass front (10 mm) framed in blackened timber — the visual signature of the cube.
- Architectural flat-roof structure. The roof is rated for a planted top (sedum, ballast, solar) or stone topper. Sauna integrates with landscape instead of imposing on it.
- Six-person interior with wraparound upper bench. The upper bench follows three walls so a group can talk facing each other rather than in a line.
- High-output 9 kW heater. Fast climb to 190 °F and a long, soft heat hold — sized for the larger volume.
- Nordic Spruce + blackened framing. Kiln-dried spruce structure with a blackened-timber facade frame that ages gracefully without bleaching.

Install & setup
Freight pallet, curbside. Because of size and weight we recommend two adults with a flat dolly and a third helper for the facade glass lift. Assembly is one full day for a careful build.
Foundation: a level 9' × 8' poured-concrete pad is the recommended foundation. A rated deck (≥60 lb/sqft) also works. Plan for adequate drainage around the perimeter.
Maintenance
The blackened facade frame is finished with a UV-stabilized exterior treatment; refresh every 2–3 years. The 10 mm glass facade cleans with any non-abrasive glass cleaner. Rotate volcanic stones annually; replace any fractured stones. Inspect roof seals once a year if a planted top is installed.
What's not included
- Foundation pad — site-specific, sourced locally
- Electrical work — licensed electrician required
- Green-roof planting medium / sedum (if you're going that route)
