Description
The Huum CORE Aspen is the compact CORE electric sauna heater finished with natural aspen wood side panels, so the heater blends with a wood-lined sauna. Choose a black or stainless steel inlay trim around the stones. It suits home saunas of 177 to 566 cubic feet, and this package includes the Huum UKU Local digital control and sauna stones.
Aspen wood finish
Huum makes the CORE side panels from natural wood in alder, aspen and thermo-aspen. Huum notes the wood finish reduces the chance of touching the hot metal, which many families with children prefer. This listing is the aspen version.
Compact and bench friendly
The small footprint and short safety distances allow corner placement or full embedding in a sauna bench. The stainless steel elements sit in direct contact with about 66 lb of stones for steam.

- The listed 15.16 x 15.16 x 32.7 in size is Huum's heater figure; check the manual for the finished size with panels before you build a bench around it.
- Electric sauna heaters must be installed by a licensed electrician per the manual and local code.
