FAQ
Questions we hear most.
Is the 9 kW heater enough?
For this cabin size, yes, overspec’d actually. The HUUM Drop reaches Finnish dry-sauna temperatures in 30 minutes and holds steady for hours.
Will it fit in my side yard?
If you’ve got 6 feet of width and 9 feet of depth with overhead clearance, yes. The smaller crane crew can set NOOK in places the larger suites can’t reach.
Can I run 240V where the panel is full?
240V · 40A is the minimum. Many homes can swap a tandem breaker or add a sub-panel. Your electrician will know in 5 minutes.
Adding cold plunge?
+$7,900 standalone Partnered with Cold Life Vertical. Own 120V circuit. NOOK is sauna-only by design.
Foundation?
A level pad, pavers or concrete. The smaller footprint means many existing decks can support it directly.
