HIVE Mini is the smaller member of HUUM's stone-first HIVE family. The round basket makes the heater a visual centerpiece while 331 lb of stones store heat and produce the gentle, rich, long-lasting steam that defines the HIVE design. It is a strong fit when you want the feel and appearance of HIVE but do not need the output or 528-lb stone mass of the full-size HIVE.
Every current HIVE Mini includes HUUM's stainless steel air tunnel as standard equipment. It improves airflow through the center of the heater, supports the heating elements, and helps prevent element overheating. HUUM's product training reports approximately 25% faster room heating and explains that the improved airflow and support are designed to help the elements last longer.
This is the latest HIVE Mini configuration. The air tunnel, four adjustable legs, and current HIVE installation and operation manual are included with the heater.
| Current U.S. model | Room volume | Amperage | Breaker | Copper wire | Minimum combustible clearance |
|---|---|---|---|---|---|
| HIVE Mini 6, 6.0 kW | 177 to 318 ft³ | 25 A | 30 A | 10 AWG | 2.4 in (manual table: 2 2/8 in) |
| HIVE Mini 9, 9.0 kW | 283 to 460 ft³ | 37.5 A | 50 A | 6 AWG | 3.6 in (manual table: 3 17/32 in) |
| HIVE Mini 11, 10.6 kW | 354 to 566 ft³ | 43.75 A | 50 A | 6 AWG | 4.4 in (manual table: 4 11/32 in) |
All three current U.S. models are 240V, single-phase and measure 18 1/8 inches in diameter by 29 17/32 inches high. The manual requires 47 1/4 inches from the top of the heater to the ceiling. For a floor-mounted HIVE Mini, the heater height plus that clearance produces a derived floor-to-ceiling installation envelope of approximately 77 inches. Final sizing, clearances, cable selection, and installation must follow the current U.S. manual and local code.
Use only clean, durable 2 to 4-inch sauna stones. HUUM's product training instructs installers to keep the air tunnel clear of stones while covering the heating elements completely. Place stones loosely enough for air to move through the heater, do not force stones between the elements, and inspect and repack the stone bed at least annually as stones settle and degrade.
HUUM's current limited warranty is 3 years for private use and 1 year for commercial use. Heating elements, accessories, sauna stones, and controller sensors are excluded. A licensed professional electrician must install and connect the system, and proof may be required for a claim. Open the current warranty and manuals in the Manuals & Documents tab for the complete terms.
No. The heater, adjustable legs, air tunnel, and heater manual are included. A compatible UKU control and ten boxes of Stones 24 are required and sold separately.
The large stone mass stores heat and increases the stone surface available for water. That is what gives HIVE Mini its gentle, abundant, long-lasting steam instead of a sharper burst from a low-stone heater.
Start with the finished interior volume, add the manual's 3.3 ft³ adjustment for every square foot of cold or uninsulated surface, then choose the model whose full range contains the adjusted volume. When a room sits near a boundary, review the construction, glazing, ventilation, and desired warm-up time with Sauna Marketplace before ordering.
Yes. HUUM provides DWG, OBJ, SKP, IFC, and 3DS files, including versions with the safety rail, on the official HIVE Mini resources page.
HUUM HIVE Mini puts 331 lb of stones into a compact 18 1/8-inch floor heater for gentle, long-lasting steam. The current 2025+ version includes HUUM’s stainless steel air tunnel, engineered to improve airflow, speed warm-up, support the heating elements, and help them last longer. Choose 6, 9, or 10.6 kW for current 240V U.S. room ranges of 177 to 566 cubic feet. A HUUM UKU control and ten 33-lb boxes of 2 to 4-inch stones are required and sold separately.
We recommend UKU Wi-Fi Glass, preselected for new packages.

★★★★★“I couldn't be happier with the service at SaunaMarketplace, Ben was incredibly thorough with his service and expertise and guided me through every step of the purchase process.”
★★★★★“First of all I want to say Ben was fantastic and very informative with all the products on his website. He recommended the Saunum Air and this was the best decision for my 6x8 ft 7 feet high cedar sauna. I got the 7kw with Wi-Fi and the power is plenty. I can take a dry sauna with no water on the rocks or add water and it becomes a steam room. The best part is when you turn the fan on and add water you can sit at lower level and not get too hot or cold. … I have been in saunas most of my life and Saunum changes the game. It is built solidly and pumps out tons of heat. I would recommend this unit big time Saunum hit it out of the park with the fan system. … Before you buy a sauna heater make sure you talk to Ben about this unit and the benefits.”

HUUM's product training reports approximately 25% faster room heating and explains that the improved airflow and support are designed to help the elements last longer.
This is the latest HIVE Mini configuration. The air tunnel, four adjustable legs, and current HIVE installation and operation manual are included with the heater.
| Current U.S. model | Room volume | Amperage | Breaker | Copper wire | Minimum combustible clearance |
|---|---|---|---|---|---|
| HIVE Mini 6, 6.0 kW | 177 to 318 ft³ | 25 A | 30 A | 10 AWG | 2.4 in (manual table: 2 2/8 in) |
| HIVE Mini 9, 9.0 kW | 283 to 460 ft³ | 37.5 A | 50 A | 6 AWG | 3.6 in (manual table: 3 17/32 in) |
| HIVE Mini 11, 10.6 kW | 354 to 566 ft³ | 43.75 A | 50 A | 6 AWG | 4.4 in (manual table: 4 11/32 in) |
All three current U.S. models are 240V, single-phase and measure 18 1/8 inches in diameter by 29 17/32 inches high. The manual requires 47 1/4 inches from the top of the heater to the ceiling. For a floor-mounted HIVE Mini, the heater height plus that clearance produces a derived floor-to-ceiling installation envelope of approximately 77 inches. Final sizing, clearances, cable selection, and installation must follow the current U.S. manual and local code.
Use only clean, durable 2 to 4-inch sauna stones. HUUM's product training instructs installers to keep the air tunnel clear of stones while covering the heating elements completely. Place stones loosely enough for air to move through the heater, do not force stones between the elements, and inspect and repack the stone bed at least annually as stones settle and degrade.
HUUM's current limited warranty is 3 years for private use and 1 year for commercial use. Heating elements, accessories, sauna stones, and controller sensors are excluded. A licensed professional electrician must install and connect the system, and proof may be required for a claim. Open the current warranty and manuals in the Manuals & Documents tab for the complete terms.
No. The heater, adjustable legs, air tunnel, and heater manual are included. A compatible UKU control and ten boxes of Stones 24 are required and sold separately.
The large stone mass stores heat and increases the stone surface available for water. That is what gives HIVE Mini its gentle, abundant, long-lasting steam instead of a sharper burst from a low-stone heater.
Start with the finished interior volume, add the manual's 3.3 ft³ adjustment for every square foot of cold or uninsulated surface, then choose the model whose full range contains the adjusted volume. When a room sits near a boundary, review the construction, glazing, ventilation, and desired warm-up time with Sauna Marketplace before ordering.
Yes. HUUM provides DWG, OBJ, SKP, IFC, and 3DS files, including versions with the safety rail, on the official HIVE Mini resources page.

Every new complete HUUM UKU controller ordered from Sauna Marketplace ships as the latest UKU 4.2, on its own or with a HUUM heater package.

The included bench sensor measures temperature and humidity, adding a second view of sauna conditions alongside the required safety sensor above the heater. HUUM recommends installing the optional bench sensor high on the wall opposite the heater, 5 29/32 inches below the ceiling. Follow the U.S. UKU 4.2 manual for the exact installation.
Local or Wi-Fi? Local runs the sauna from the wall panel. Wi-Fi adds remote control through the HUUM app. Choose the package and panel finish that suit your sauna.
