The HUUM CORE Aspen is the customisable-inlay variant of the HUUM CORE range — an Aspen wood exterior electric sauna heater with a distinctive additional feature not found in the other CORE variants: customisable inlay finishes that allow the aesthetic of the heater exterior to be further personalised beyond the standard Aspen panel appearance. The Aspen wood panels match naturally with the warm interior tones of most sauna cabins, providing the same integrated aesthetic and burn-protection function as the other wood-exterior CORE variants.

Like the CORE Alder, the Aspen variant is UKU-compatible with the controller sold separately — making it the appropriate choice for buyers who already have a UKU system or who prefer to specify their own control configuration. The same 66 lbs of stones in direct element contact, the same 6.5 / 9 / 10.5 kW range for 177–566 cubic feet, and the same bench-embeddable compact footprint as every CORE variant. Backed by the 3-year residential warranty.

Aspen wood outside. Industrial stainless steel inside. Customisable inlay to make it yours. The HUUM CORE Aspen — Estonian engineering, your aesthetic. 🌿

🌳
Aspen Wood Panels + Customisable Inlay — What Sets This Variant Apart
The HUUM CORE Aspen features natural Aspen wood exterior panels — a lighter, clean-grained wood with a naturally bright, warm aesthetic that complements most sauna interior tones. The customisable inlay finishes allow additional personalisation of the heater's appearance beyond the standard panel — matching the CORE Aspen to bespoke interior details. The Aspen panels simultaneously provide a protective barrier against accidental contact with the hot stainless steel beneath. UKU controls are compatible but sold separately — contact us to configure the right control solution for your installation.

🌳Aspen wood exterior panels + customisable inlay finishes — the CORE Aspen's exterior is finished with natural Aspen wood panels — a lighter-toned wood with a clean, bright grain that integrates naturally with most sauna interior aesthetics. The customisable inlay finish option is specific to this variant, allowing further personalisation of the heater's visual presentation beyond the panel itself. The Aspen panels simultaneously serve as a protective barrier against accidental contact with the hot stainless steel surface beneath — combining aesthetics and safety in a single design element
🏗️Industrial-quality stainless steel core — direct stone contact — the Aspen wood exterior is the design layer. The performance layer beneath it is industrial-quality stainless steel heating elements in direct contact with the 66 lb stone load. Direct element contact heats stones faster, retains heat longer, and produces more consistent steam than alternative arrangements — rapid heat-up times and abundant, soft steam with every ladle of water
📦Compact footprint — minimal safety distances — bench-embed capable — the same compact engineering as every CORE variant: minimal safety clearance requirements enabling installation in tight corners and direct embedding into sauna bench seating. In a bench-embed installation, the Aspen wood exterior integrates with the surrounding bench material, creating a clean, cohesive appearance throughout the sauna interior
🎛️UKU controls compatible — sold separately — the CORE Aspen is fully compatible with HUUM's UKU control system for precise temperature management. The UKU is sold separately, making this variant appropriate for buyers who already have a UKU system, who are adding to an existing HUUM installation, or who prefer to specify their own control configuration independently. Contact us to discuss UKU control options alongside your CORE Aspen order
