We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Product Guide

The HIVE sauna experience in a smaller footprint

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.

The current 2025+ air tunnel version

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.

Choose the correct HIVE Mini

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.

What is included and what is required

Included

  • HUUM HIVE Mini electric sauna heater
  • Four adjustable legs
  • Current-generation air tunnel
  • Current installation and operation manual

Required and sold separately

Recommended planning accessories

  • HUUM HIVE safety rail, selecting Rail HM for HIVE Mini. HUUM strongly recommends a safety rail around the heater.
  • HUUM HIVE reflector, selecting Reflect HM when the project needs the HIVE Mini version.
  • HUUM HIVE Mini embedding flange when the heater passes through a bench platform.

Sizing and installation notes that matter

  • Account for cold surfaces: for each square foot of glass, masonry, tile, brick, concrete, or other uninsulated surface, add 3.3 cubic feet to the calculated sauna volume before selecting the heater.
  • Plan around roughly one hour of warm-up: HUUM says a properly insulated, correctly sized room usually reaches bathing temperature in about an hour. Wi-Fi UKU control lets you start the heater before you enter the sauna.
  • Embedding is allowed: at least 13 25/32 inches, or 13.8 in, of the heater must remain above the bench surface. Use the correct HIVE Mini flange and preserve every manual clearance.
  • No extension box is required for these models: the current 240V HIVE Mini 6, 9, and 11 are within the current UKU's direct capacity. The full-size 12, 15, and 18 kW HIVE models are a different system.

Load the stones correctly

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.

Warranty

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.

HIVE Mini questions

Does HIVE Mini include the controller and stones?

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.

Why does HIVE Mini use so many stones?

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.

Which model should I choose?

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.

Can designers download a HIVE Mini model?

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 Electric Sauna Heater | 6, 9 & 10.6 kW

(1 customer review)

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.

Fast and Free Shipping!

Most HUUM HIVE packages leave our Chicago warehouse in 2 to 3 business days. They travel by freight to the distribution hub nearest you, and the carrier calls you to book a delivery window. Plan on someone being there to receive it.

Choose a HUUM UKU controller (required)

Your heater will not run without a UKU. Local mounts outside the hot room and runs the sauna from its own panel. Wi-Fi does the same and adds scheduling and remote start from the HUUM app, which is what you want when the sauna is not ten steps from the couch. Every finish below is the same controller underneath, so pick on looks and budget. Already own a UKU? Take the first option and we will check yours against this heater before anything ships. We recommend UKU Wi-Fi Glass, preselected for new packages.

Add the required stones: HIVE Mini 6/9/10.6 kW

The HIVE Mini 6, 9 and 10.6 kW holds about 331 lb of 2 to 4 inch stones, and stones do not come in the box with the heater. That comes to 10 boxes. Stack them loosely so air can move between them and the elements stay covered, and plan on restacking once a year.

Public reviews and notes owners sent our team, word for word. Names are shortened to a first name and last initial, or to initials.

“The consultations were a tremendous help in our final stove selection, and the whole process was easy. We felt well supported when making this decision and purchase.”

Lawrence F.

“Excellent service and consultation”

Dennis A. · HUUM HIVE Flow owner

“We fired it up for the first time tonight and everything is great.”

Emily S. · HUUM HIVE owner

“Love the drop 7.5! Buying experience was great.”

L. J. · About the HUUM DROP

“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.”

T. H.

“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.”

Bob H. · About the Saunum AIR

“Great service - easy delivery!”

Even Better Embedded

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.

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.

What is included and what is required

Included

  • HUUM HIVE Mini electric sauna heater
  • Four adjustable legs
  • Current-generation air tunnel
  • Current installation and operation manual

Required and sold separately

Recommended planning accessories

  • HUUM HIVE safety rail, selecting Rail HM for HIVE Mini. HUUM strongly recommends a safety rail around the heater.
  • HUUM HIVE reflector, selecting Reflect HM when the project needs the HIVE Mini version.
  • HUUM HIVE Mini embedding flange when the heater passes through a bench platform.

Sizing and installation notes that matter

  • Account for cold surfaces: for each square foot of glass, masonry, tile, brick, concrete, or other uninsulated surface, add 3.3 cubic feet to the calculated sauna volume before selecting the heater.
  • Plan around roughly one hour of warm-up: HUUM says a properly insulated, correctly sized room usually reaches bathing temperature in about an hour. Wi-Fi UKU control lets you start the heater before you enter the sauna.
  • Embedding is allowed: at least 13 25/32 inches, or 13.8 in, of the heater must remain above the bench surface. Use the correct HIVE Mini flange and preserve every manual clearance.
  • No extension box is required for these models: the current 240V HIVE Mini 6, 9, and 11 are within the current UKU's direct capacity. The full-size 12, 15, and 18 kW HIVE models are a different system.

Load the stones correctly

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.

Warranty

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.

HIVE Mini questions

Does HIVE Mini include the controller and stones?

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.

Why does HIVE Mini use so many stones?

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.

Which model should I choose?

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.

Can designers download a HIVE Mini model?

Yes. HUUM provides DWG, OBJ, SKP, IFC, and 3DS files, including versions with the safety rail, on the official HIVE Mini resources page.
