For private gardens
Warm light at the foot of the garden.
A 10 m² Finnish-style cabin sauna, finished to look like it grew where it stands. Two stocked finishes, Black or Oak. No concrete. Under two hours on site.
It reads as architecture, not as a shed.
Rinse under the open sky.
The cabin comes with a recessed vestibule in the same timber — robe hooks and a slatted floor with a linear drain, with an optional outdoor rain shower plumbed into the alcove.
Rinse before the heat, cool down after it, under the open sky. It is the part guests remember.

Five questions before the dossier
-
How much site preparation does it need?
Less than you would expect. The helical-pile foundation installs in a single morning — six steel piles, no concrete, no excavation. We need 2.5 m × 4.0 m of relatively level ground (slope tolerance up to 15°), a power feed within 6 m, and clear crane access for the cabin lift. The site is otherwise untouched.
-
Can it be removed if I move house?
Yes. The piles unscrew, the cabin lifts off, and the ground is left as found. This is the same property that makes the install palatable for landlords on leased land.
-
What does running it cost?
The HUUM Drop 6 kW heater draws roughly 4.5–5 kWh per heat-up cycle (warm to 80°C). Insulation rating is Energy Rating A officially verified, so heat-loss during a session is minimal. Annual running cost depends on usage frequency and local electricity tariff; we send a per-property estimate with the dossier.
-
Can I customise the finish?
Two stocked exterior finishes — Black and Oak. Two named interior upgrades — red cedar (+$9,720 USD) and Millboard composite exterior (+$15,984 USD, 25+ year warranty). We do not run bespoke material variants; the single SKU is what keeps lead time at 8–10 weeks.
-
What's the warranty?
Three-year structural warranty covering frame, cladding, glazing seals, and the EPDM roof membrane. The EPDM membrane itself carries a separate 50-year manufacturer warranty. HUUM heater warranty per HUUM's manufacturer policy.
