HUUM HIVE Mini 6STU Pkg HIVE Mini Series 6.0kW Sauna Heater Package
The HUUM HIVE Mini 6STU Package is a complete sauna heater package for rooms from 177 to 318 cubic feet, including the HIVE Mini 6kW floor-standing heater, UKU sauna control (Local Black or WiFi - selected at checkout), and 330 lbs of rounded olivine diabase sauna stones (10 boxes). The HIVE Mini is a slimmer version of the full-size HIVE heater - designed for smaller sauna rooms where the full HIVE's 22" diameter is too large, the DROP series's 122-lb wall-mounted format is insufficient, and the floor-standing beehive aesthetic of the HIVE family is the preferred design. At 18.11" (460mm) diameter and 29.5" height, the HIVE Mini is meaningfully more compact than the full HIVE while still carrying 330 lbs of stone - nearly three times the DROP series's capacity. No UKU Extension Box is required for the 6kW model.
HIVE Mini - the slimmer HIVE for smaller rooms with floor-standing aesthetics
The HUUM HIVE series divides into two distinct product lines based on room size and heater scale. The full HIVE (12kW, 15kW, 18kW) has a 22" diameter cage and covers rooms from 424 to 955+ cubic feet - a large, commanding floor-standing heater suited to large residential and commercial sauna rooms. The HIVE Mini (6kW, 9kW, 10.5kW) has an 18.11" (460mm) diameter cage and covers rooms from 177 to 706 cubic feet depending on output - a slimmer floor-standing heater that brings the beehive open-cage design and large stone capacity of the full HIVE into rooms where the full HIVE would be oversized. The HIVE Mini 6kW with 330 lbs of stones in a 177-318 cu ft room is the specific case where a bather wants more stone mass than the wall-mounted DROP can provide, in a compact floor-standing format, without the electrical complexity of the full HIVE's dual-circuit requirement.
330 lbs of stone from a floor-standing heater on a standard 30A circuit
The HIVE Mini 6 carries 330 lbs (10 boxes) of rounded olivine diabase stones on a standard single 30A / 10 AWG circuit - the same electrical specification as the wall-mounted HUUM DROP 6kW. The critical difference is stone mass: the DROP 6 carries 122 lbs; the HIVE Mini 6 carries 330 lbs. More stone mass means more thermal capacity, slower steam release, longer sustained heat after the elements have cycled, and softer, longer-lasting loyly when water is ladled. For buyers in the 177-318 cu ft room range who want more stone mass than the DROP provides and prefer a floor-standing installation over a wall-mounted one, the HIVE Mini 6 is the appropriate choice - at the same electrical requirement as the DROP 6.
Air tunnel pre-installed, adjustable legs, bench-embedding possible
The air tunnel is pre-installed in this package as standard. It directs airflow more efficiently through the 330-lb stone mass during the warm-up cycle, speeding up heating and extending element life. The HIVE Mini has adjustable legs for levelling on uneven sauna floors. Like the full HIVE, the HIVE Mini can also be partially embedded into a sauna bench using the HIVE Mini embedding flange (sold separately), allowing the heater to sit flush with the bench level in custom sauna installations. The HIVE Mini stands directly on the sauna floor without any wall mounting hardware. The optional HIVE Mini safety railing is recommended to prevent accidental contact with the hot heater surface.
Complete 6kW floor-standing sauna heater package for rooms from 177 to 318 cubic feet. Includes HIVE Mini 6kW heater, UKU control (Local Black or WiFi - select at checkout), and 330 lbs of rounded olivine diabase stones (10 boxes). The slimmer HIVE for smaller rooms - 18.11" diameter x 29.5"H. 330 lbs stone capacity - nearly 3x the DROP series wall-mounted heater. Open beehive cage design - direct stone-to-element contact, maximum airflow. Air tunnel pre-installed - faster heat-up, extended element life. Adjustable legs. Bench-embedding possible. Single 30A breaker, 10 AWG wire - same electrical as DROP 6kW. No UKU Extension Box required. 240V / 1-phase. Max 230°F. SGS Listed. Ships on wooden pallet - scheduled delivery. 5-year warranty (elements excluded). Made in Estonia by HUUM.

Why the HUUM HIVE Mini 6STU Package stands out
330 lbs of stone on a standard 30A circuit
The HIVE Mini 6 carries 330 lbs of rounded olivine diabase stones - nearly three times the 122 lbs of the DROP 6kW - on the same standard single 30A / 10 AWG circuit. More thermal mass means slower, softer steam, more sustained heat through the session, and a more authentic sauna experience than a smaller stone load can deliver at the same output level.
Slimmer HIVE beehive design for smaller rooms
The HIVE Mini's 18.11" diameter is meaningfully more compact than the full HIVE's 22", making the beehive open-cage design accessible for rooms from 177 cu ft where the full HIVE would be oversized. The stainless steel arcs surround the stone mass with the same open-cage airflow geometry as the full HIVE, delivering even heat distribution through the full 330-lb stone load.
Floor-standing - no wall mounting required
The HIVE Mini stands directly on the sauna floor on adjustable legs. No wall bracket, no wall penetration, no overhead clearance concerns from a wall-mounted unit. Adjustable legs allow levelling on uneven sauna floors. The heater can be partially embedded into the sauna bench using the optional embedding flange for a custom flush installation.
Air tunnel pre-installed - faster heat-up
The air tunnel is included as standard in all current HIVE Mini models and is pre-installed on the heater. It directs airflow more efficiently through the 330-lb stone mass during warm-up, reducing heat-up time and extending heating element life. For a 177-318 cu ft room, faster heat-up means a shorter wait from switch-on to bathing temperature.
UKU WiFi option - remote preheat
Upgrading to UKU WiFi at checkout adds HUUM app control on iOS and Android - remote preheat, session scheduling, and temperature monitoring from anywhere. No UKU Extension Box is required for the 6kW model. The WiFi option connects directly to the UKU control without additional hardware. Start the sauna from the app before leaving and arrive to a hot room.
HIVE Mini vs DROP - choosing between them
Both cover 177-318 cu ft on a 30A / 10 AWG circuit. The DROP 6 is wall-mounted, compact, 122 lbs of stones. The HIVE Mini 6 is floor-standing, 18.11" diameter, 330 lbs of stones. The decision is mounting preference and stone mass priority. For wall-mounted minimalism: DROP 6. For floor-standing beehive aesthetics and maximum stone mass on the same circuit: HIVE Mini 6.
About HUUM
Made in Estonia - SGS Listed
HUUM HIVE Mini 6STU. 6kW. 177-318 cu ft. The slimmer HIVE - floor-standing, 330 lbs of stone, standard 30A circuit.
HUUM is an Estonian sauna heater company. The HIVE Mini 6STU Package brings the beehive open-cage design and large stone mass of the HIVE family into smaller sauna rooms on a standard 30A residential electrical circuit. At 330 lbs of stone capacity in an 18.11" diameter floor-standing form, the HIVE Mini 6 sits between the wall-mounted DROP series (122 lbs) and the full HIVE series (528 lbs) in both scale and stone mass - the appropriate choice for buyers who want a floor-standing heater with more thermal mass than the DROP provides, without the dual-circuit electrical requirement of the full HIVE. We are an authorized HUUM dealer.

HIVE Mini 6 vs 9 vs 10.5 - choosing the right output for the room
All three HIVE Mini models share identical body dimensions - 18.11" (460mm) diameter, 29.5" height - and the same 330-lb stone capacity. The selection is based on room size and adjusted cubic footage. HIVE Mini 6kW: 177-318 cu ft, single 30A / 10 AWG. HIVE Mini 9kW: 318-530 cu ft, single 50A / 8 AWG. HIVE Mini 10.5kW: 353-706 cu ft, single 50A / 8 AWG. The 6kW is the only HIVE Mini model that operates on a standard 30A circuit - the 9 and 10.5kW require a 50A circuit and 8 AWG wire. For rooms from 177-318 cu ft where a 30A circuit is available, the HIVE Mini 6 is the correct and most electrically efficient choice. Use the HUUM heater calculator in the Size Your Sauna document below to verify the adjusted cubic footage of the specific sauna room before selecting.

I am an executive at a large technology company, and represent a major lifestyle society with over 400 members as its president. My passion is lifestyle, and I have spent considerable time and resources testing and reviewing a number of therapies from a large number of suppliers. Allow me to say that the experience I have had so far with this company and product has been beyond exceptional. First, the customer care I have received is second to none. The team has been highly responsive no matter the day and time, provided accurate and sincere information, and given me the feeling of being looked after. I have not experienced this level of customer care before, and I would like to highlight that it is exemplary and I am ultimately grateful for this. Secondly, the product is of high quality and works better than expected. I have become an avid fan of HBOT therapy since I have received your product and would wholeheartedly recommend this therapy and your company to anybody. Lastly, what your company is doing for people is exceptional as it enables the wider public to have a revolutionary therapy at a highly affordable rate at home. Thank you for your time, effort and contribution to society. Please continue this great mission! Best regards.
Clinical excellence in a home setting. The UltraCare XT handles everything my wife's complex care protocol requires. The range of adjustment is excellent and the motor system is quiet and smooth. Her nursing team commented that having proper clinical equipment at home has made a genuine difference in her care quality. Mediriser was professional throughout.
I am really happy with my OxyRevo chamber. The support team was really helpful in helping me assemble it and to get the most out of my chamber. They are well priced for the quality! Thanks!
We recently purchased a Forward 90 from OxyRevo to treat my 5 year old son. He has horrible sores and itching from severe eczema. We had been paying $150 per week to have the HBOT treatment at a clinic. So, we decided it was time to buy an in-home unit. The HBOT treatment works wonders, and heals his skin within a day or two. We did intensive research to find the best system for our family, evaluating a dozen or more systems. After deciding on the OxyRevo Forward90, we couldn't be more happy. The unit is extremely high quality, comfortable, and easy to use. We really like that we can enter the chamber with our son, and sit upright while we watch movies together inside during treatment. The customer service has been top notch. The team even met with me via video chat to walk me through the showroom and explain the device in person before we bought it. We highly recommend OxyRevo, and our son's skin is as clear as it's ever been!
Compact and efficient the Chair Pro is ideal if space is limited. It fits comfortably in my home office and I do sessions during my lunch break. The 1.4 ATA is great for general wellness and cognitive performance. Mediriser was professional and communicative throughout the entire buying process.
The lying position in the Airvida Ultra makes sessions feel like true rest rather than a medical procedure. After six weeks of regular use my inflammation markers have dropped noticeably according to my doctor. The hard shell construction is premium and the 2.0 ATA ceiling gives flexibility for various therapeutic goals. Mediriser handled delivery and setup support perfectly.
The 550lb capacity of the Oasis Expandable was the primary reason we chose it and it handles the load with ease. The hi-low function is smooth and the expandable width means my husband has room to move comfortably. All electric adjustments work reliably. Mediriser was thorough in confirming the capacity and dimensions for our room before we ordered.
The Value Flex lives up to its name — excellent value without any compromise on the things that matter. Head and foot adjustment works reliably and the motor is quiet. My mother uses it daily and has reported improved sleep quality and less morning stiffness. Mediriser had it in stock and delivered faster than the estimated timeline.
The long range battery on the IQ-9000 is what sold me and it absolutely delivers. My wife can cover 25+ miles on a full charge which means a full day out without range anxiety. The auto-recline option is something she uses daily for comfort. Premium chair at a price that beat every local dealer. Mediriser made purchasing effortless.
Reliable nitrogen cryotherapy chamber that has been in daily commercial use for eight months. Consistent cold delivery session after session and our technicians appreciate the straightforward operation. Client results for inflammation and recovery have been excellent. Mediriser handled our commercial purchase professionally from quote to delivery.
Top tier product. I run a small wellness center and added the Airvida Ultra to our services. Clients specifically request it. The build quality inspires confidence and it has been running flawlessly for four months with daily use. Mediriser's support team is responsive and knowledgeable great vendor to work with.
