Product Details

HUUM Hive Flow Mini LS Wood Burning Sauna Stove

HUUM Hive Flow is the newest sauna heater on HUUMs collection. What’s unique about the HUUM Flow is its furnaces patent-pending design. The air Flows inside this heater in a unique pattern that allows 75% of the heat generated from the firewood to directly heat up your sauna, rather than escape through the chimney. Compared to traditional sauna stoves, you have to use less firewood in the process of heating up your sauna. This makes the HUUM Flow not only environmentally friendly but also the most economical sauna stove on the market.

Flow Mini LS version has an elongated firebox. This allows you to embed the heater through a wall and load from another room next to the sauna. The advantage is that your sauna stays clean from all the debris, and the heater can heat the room next to it and act as a fireplace there. You can also get the LS version if you just want to use longer firewood.

Key Features

Cozy Atmosphere

High Stone Capacity

Extended Heat

Chimney Options

Cozy Atmosphere

Large glass door on the furnace creates a cozy ambiance on the sauna. Enjoy the mesmerizing flames dancing on the fire chamber while enjoying the most equal sauna heat offered by any wood stove.

High Stone Capacity

The best sauna heaters have high rock capacity. Furnace heats up the rocks, and the rocks themselves radiate the pleasant and equal heat to the sauna. That’s why even the HUUM Hive Flow Mini carries a massive 231 lbs of sauna stones.

Extended Heat

Enjoy the heat & steam even 30 minutes after the fire has extinguished, thanks to the equally heated stones acting as heat reservoirs.

Chimney Options

HUUM Hive Flow was designed with two separate chimney connections. You can connect the chimney to the back of the heater in order to embed it through the wall. Alternatively, you can go with the traditional option and connect the chimney on top of the stove and go through the roof. You can find the chimney kits here: Thru Ceiling Chimney Kit and Thru Wall Chimney Kit.

Highly Recommend This Company

The team at Soaknsweat was absolutely incredible. I honestly didn’t think customer service like this still existed. Kris and the crew actually answered the phone, patiently walked me through every question, and helped me make several key decisions for my sauna setup. They followed up quickly, were extremely professional, and truly earned my business and recommendation. Their YouTube content was also a huge help during the planning phase — and one of the main reasons I chose to order from them. Thanks, team!

Building Phase

I’m currently in the process of designing and building a sauna. After a lot of online research and frustration, I discovered Soak 'n Sweat — and it was a game changer. Their educational page covers every aspect of sauna design and answered nearly all my questions through detailed articles and videos. When I reached out via chat, Kris patiently addressed the rest of my questions without any pushy sales tactics. These folks really know their stuff, provide great products, and make the whole experience smooth and informative. Thank you!

I’m extremely impressed with their customer service and highly recommend Soak 'n Sweat to anyone looking for quality products and exceptional support.
