3D model basis
Shared HUUM body/envelope for US and EU planning
HUUM HIVE US and EU rows use the same SaunaDesignPro 3D body/envelope for placement. Do not treat that as the same electrical SKU; use the selected regional manual for output, phase, breaker, cable, controller, listing, and warranty.
- Certified control system required
- Add glass/tile/brick penalty before sizing
- Elements must be fully surrounded by stones
- US and EU HUUM electrical packages use separate regional specs/listings; share the 3D body model only after confirming the exact market SKU
- Do not install more than one heater in one sauna room
- HUUM publishes UKU Classic and UKU Glass/Mirror/Gold controller 3D resources; SaunaDesignPro places the selected UKU controller outside the hot room in 3D planning.
- HIVE/HIVE Mini have high stone mass; the manual limits the sauna room to one heater.
