A finished opening for full-size HIVE
The HIVE flange is sized for the full-size electric heater. It is a different part from the smaller HIVE Mini flange.
Why embed your heater?
Good sauna design aims to keep your feet near or above the top of the heater stones. Warm air rises, so a low foot bench can leave your feet in cooler air while your head gets hot. Planning the seat and footrest heights around the stone level helps bring more of your body into the warmer part of the sauna.
Embedding your full-size HUUM HIVE into a raised bench or platform lets you build the layout around the heater, with this flange finishing the opening. The bench and footrest heights create the relationship between your feet and the stones; the flange alone does not change it. Keep the required portion of the heater above the surrounding surface and follow the heater and flange manuals for clearances, ventilation, mounting and service access.
Built for
HUUM HIVE Electric Sauna Heater with Included Air Tunnel | 12, 15 & 18 kW
The full-size HIVE electric heater this flange is made for, when the heater is set partly into the bench. See the full product and build your package →
What’s included
- HIVE embedding flange
- Installation and operation manual
What it does
The Flange H trims the opening when a full-size HIVE is set partly down into the bench or platform. In HUUM’s words: “The embedding flange is useful when you are planning to install your HIVE heater partly inside the sauna bench. It is made of stainless steel and it covers up the wooden edges around the heater, leaving the final result looking refined and smooth.”
Which heater it belongs to
This is the flange for the full-size HIVE electric heater (12, 15 and 18 kW), listed by HUUM under Operating Accessories on that heater’s page. The HIVE Mini electric heater takes the separate, smaller Flange HM, 18.31 in inside diameter against 22.64 in here, so the two are not interchangeable. HIVE Flow is a different, wood-burning family and does not use this part.
- Stylishly covers wood edges around embedded heaters
- For use with HIVE sauna heaters
- Stainless steel construction

Common questions
Do I need an embedding flange?
An embedding flange is only needed when the sauna heater is being set partly down inside the bench or platform rather than standing free on the floor. HUUM describes the Flange H as useful “when you are planning to install your HIVE heater partly inside the sauna bench”, where the stainless ring covers the cut wooden edges around the heater for a smooth finish. A HIVE standing openly on the sauna floor does not need one.
What size is the HUUM Flange H?
The HUUM Flange H measures 22.64 in inside diameter and 28.94 in outside diameter. It is stainless steel and weighs 3.55 lb, and it is the embedding flange for the full-size HIVE electric heater in 12, 15 and 18 kW.
Is the HIVE embedding flange the same as the HIVE Mini one?
The full-size HIVE and the HIVE Mini use different embedding flanges and the two are not interchangeable. Flange H (part H3003022) measures 22.64 in inside diameter and 28.94 in outside diameter; Flange HM (part H3002022) measures 18.31 in inside diameter and 24.61 in outside diameter.
