150 kg of stone in a compact round heater
The HIVE Mini packs a large open stone mass into a round, beehive-shaped body. With about 150 kg of stones, it heats the room gently and holds the heat for a long, humid session.
An internal air tunnel speeds up warm-up, and adjustable legs come standard. It can also be set into a bench, as long as at least 350 mm stays above it.
More stone, softer heat
HUUM heaters hold their stones in the open, around and above the elements. A large stone mass heats the room evenly and gives a long, rolling steam when you pour, without the sharp sting of a small, hot pile.
The size tables list how many 15 kg boxes each model takes, and you can add them to your order above.
Designed and built by HUUM
HUUM designs and builds its heaters, stoves and UKU controls in Estonia. The DROP and CLIFF have both won Red Dot design awards.
Electric heaters and controls carry a 3-year limited warranty for private use (1 year commercial); heating elements are excluded.
Choose your size
Match the heater to your room's volume (length × width × height in feet). Rooms with large glass areas or little insulation usually need the next size up. Not sure? Call (888) 715-7999 and we'll size it for you.

Which size fits my sauna room?
The 6 kW suits rooms of 177–318 ft³ (5–9 m³), the 9 kW suits rooms of 283–460 ft³ (8–13 m³), the 10.5 kW suits rooms of 354–566 ft³ (10–16 m³). Large windows, glass doors or an uninsulated room can push you up a size. Send us your room dimensions and we'll confirm.
Is a control included?
Needs a HUUM UKU controller (Wi-Fi or Local), sold separately. Every HUUM electric heater runs from a UKU control system: a main module that switches the heater and a wall panel. UKU Wi-Fi lets you start and schedule the sauna from the HUUM app; UKU Local runs from the panel and can be upgraded to Wi-Fi later.
Are sauna stones included?
Stones are sold separately. This heater takes About 150 kg / 330 lb (10 boxes of 15 kg). HUUM sauna stones come in 15 kg (33 lb) boxes, and we can add them to your order.
What electrical work is needed?
A licensed electrician must install the heater and the UKU controller. HUUM requires proof of a licensed installation for warranty claims. Use the breaker size listed for your model and check local code before booking the work. HIVE 12–18 kW heaters run on two circuits and need the extension box.
Do you ship to the US?
Yes. HUUM heaters ship across Canada and to the lower 48 US states. Prices show in your local currency at checkout. Reach out if you are in a remote area and we will confirm delivery.
