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.

You'll want to keep your heater low and your benches high for the best sauna experience. We recommend building an elevated "false floor" and embedding your HUUM HIVE Mini.
Then build a foot bench, and final bench above that floor level and you will have a dramatically improved sauna. Ask us how to get free shipping for your sauna floor and bench materials, along with your HUUM heater.
