HUUM CORE Black CORE Series Sauna Heater, Black Exterior, Up to 10.5kW

HUUM CORE Black CORE Series Sauna Heater, Black Exterior, Up to 10.5kW

The HUUM CORE Black is a floor-standing electric sauna heater with a painted black exterior, available up to 10.5kW. This listing is the heater only. A compatible UKU control unit and sauna stones are sold separately. The CORE Black is the darkest-overall finish in the CORE series - the exterior panels are painted matte black, making it the most visually recessive option in the lineup. For sauna rooms with dark interior finishes, black or charcoal hardware, and contemporary minimal aesthetics where the heater should integrate as a dark architectural element rather than contrasting with the surroundings, the CORE Black is the correct CORE choice. The CORE Black Package listing at BathingBrands bundles the heater with a UKU control and stones for a complete single purchase.

The CORE design - open basket, stone visible on all sides

The HUUM CORE heater combines an open stainless steel stone basket with exterior side panels that frame the stone mass. The open basket allows the stones to be visible through the structure on all sides, and direct stone-to-element contact throughout the full stone load ensures even heat distribution. Water ladled onto the stones produces soft, consistent steam from stones at multiple temperature levels throughout the basket depth. In the CORE Black, the painted black panels frame the visible stone mass in matte black - the combination of dark panel and natural olivine stone creates a heater that reads as a considered design element in a dark-palette sauna room rather than an appliance.

Black exterior - the darkest CORE finish, panel-supplied

The CORE series is available in five exterior options: Black (this listing), Alder (pale warm neutral wood), Thermo-Aspen (deep brown thermally modified wood), Aspen (pale cream-white natural wood), and BK/ST (no panels - customizable). The CORE Black is the only non-wood option that ships with HUUM-supplied exterior panels - painted matte black panels applied to the stainless frame. It is the most intensely dark of all the CORE variants with supplied panels, darker in tone than Thermo-Aspen which is deep brown but still recognizably warm timber. For sauna rooms where charcoal, black slate, dark stone, or matte black surfaces define the interior palette, the CORE Black is the CORE finish that integrates most completely.

Up to 10.5kW - output selected at purchase

The CORE Black is available in multiple output configurations up to 10.5kW. The specific output selected determines the room coverage and electrical specification. UKU control (Local Black or WiFi) and sauna stones are required for operation and sold separately at BathingBrands. A UKU Extension Box may be required depending on the output level selected - confirm with the control unit specifications. A licensed electrician is required. Do not connect to a GFI/GFCI breaker.

Why the HUUM CORE Black stands out

Darkest overall CORE - matte black panels

The CORE Black is the most intensely dark option in the CORE series. The painted matte black exterior panels sit darker than even Thermo-Aspen's deep brown, making the CORE Black the correct choice for sauna rooms where absolute integration with a dark, monochrome, or charcoal material palette is the goal. Against black slate, dark basalt stone, or matte black hardware and trim, the CORE Black reads as part of the room rather than a contrasting element.

HUUM-supplied panels - ready-finished on delivery

Unlike the CORE BK/ST which arrives without side panels for owner-applied custom cladding, the CORE Black ships with painted black exterior panels already applied. The heater is ready to install and operate once the control and stones are added - no custom panel work required. For buyers who want a black CORE without the project of sourcing and applying custom panels, the CORE Black is the direct ready-to-install option.

Open basket - black frame and visible stone

The CORE's open stainless steel basket presents the stone mass through the structure on all sides, with the black panels framing it. The visual pairing of matte black exterior and natural olivine stone creates a heater with a contemporary, sophisticated material combination - dark metal framing natural stone - suited to the same sauna room aesthetic as black slate floors, dark timber benches, and industrial hardware.

Up to 10.5kW - covers a wide room range

The CORE Black is available up to 10.5kW, covering sauna rooms across a wide size range depending on the output configuration selected. Use the Size Your Sauna document below to confirm the correct output for the specific room before ordering. The output level selected also determines the electrical specification and whether a UKU Extension Box is required.

CORE Black Package - complete bundled option

The CORE Black Package listing at BathingBrands bundles the heater with a UKU control and stones for a single complete purchase. This standalone heater listing is for buyers sourcing the heater separately - replacing a heater in an existing CORE installation, pairing with a specific control already on hand, or completing a multi-component order in separate transactions.

SGS Listed - 5-year warranty - made in Estonia

The HUUM CORE Black is SGS Listed for safety compliance and manufactured in Estonia by HUUM. The 5-year limited warranty covers defects in manufacturing and materials under normal use conditions, with heating elements carrying their own separate warranty period. Note that the CORE BK/ST (customizable variant) carries a shorter 3-year warranty; all other CORE panel variants including the CORE Black carry the full 5-year coverage.
