Product Overview

The Right Trim Detail for a Partially Embedded HIVE Mini

The HUUM Flange HM is an embedding flange for HIVE Mini series sauna heaters. Bathing Brands describes it as useful when installing your HIVE heater partly inside the sauna bench, with stainless steel construction that covers the wooden edges around the heater for a refined, smooth final result.

The flange is designed to sit around the heater opening, creating a clean transition between the sauna bench and the heater body. This matters because a partially embedded heater installation requires careful finish work around the cutout. Without a proper flange, the bench opening can look raw, exposed, or unfinished.

Related dealer specifications list the Flange HM with an 18.31" inside diameter and 24.61" outside diameter, and confirm that it is made from stainless steel for use with HIVE Mini sauna heaters.

Why You'll Love it!

Designed for HUUM HIVE Mini Heaters

The Flange HM is made specifically for HUUM HIVE Mini series sauna heaters. It is not intended for HUUM DROP, STEEL, CLIFF, full-size HIVE, Harvia, Saunum, or other non-HIVE Mini heaters.

Finishes Partially Embedded Heater Installations

Use the Flange HM when planning to install a HIVE Mini heater partially inside or through a sauna bench or platform.

Covers Exposed Wood Edges

The flange covers the wooden edges around the heater cutout, giving the sauna bench a cleaner and more finished appearance.

Stainless Steel Construction

Built from stainless steel, the Flange HM is designed to complement the heater and withstand the sauna environment.

Refined Built-In Look

The flange helps the heater feel integrated into the sauna design rather than simply placed into a rough opening.

Ideal for Custom Sauna Builds

Perfect for custom bench layouts, premium sauna rooms, outdoor sauna builds, and design-forward installations where finish details matter.

What Makes the HUUM Flange HM Different?

It Turns a Bench Cutout Into a Finished Design Detail

A partially embedded heater can look beautiful, but only when the surrounding bench opening is finished properly. The HUUM Flange HM creates that clean transition between the sauna bench and the HIVE Mini heater.

Instead of leaving exposed wood edges around the heater cutout, the stainless steel flange gives the installation a more refined, seamless appearance. For customers investing in a premium sauna, this small detail can make the entire heater area feel more intentional and professionally designed.

The Flange HM is especially valuable when the heater is a visible focal point of the room, such as in glass-front saunas, modern outdoor sauna kits, and custom luxury sauna interiors.

Is the HUUM Flange HM Right for Your Sauna?

The HUUM Flange HM is the right accessory if you are installing a HUUM HIVE Mini sauna heater partially inside a sauna bench or platform and want the cutout area to look clean, finished, and professional.

It is especially useful for:

HUUM HIVE Mini embedded installations
Custom sauna benches
Platform-style heater layouts
Luxury outdoor sauna builds
Glass-front sauna interiors
Modern Scandinavian sauna designs
Sauna builders who want a finished trim detail
Homeowners who want a cleaner built-in heater appearance

If your HIVE Mini heater will be installed fully freestanding on the floor with no bench cutout, this flange may not be needed.

Resources & Guides

Installation Notes

The HUUM Flange HM should be installed according to HUUM’s official installation instructions and the requirements for your specific HIVE Mini heater model.

General installation guidance:

Confirm compatibility with your HIVE Mini heater before ordering
Review the official HUUM heater and flange manuals before cutting the bench
Confirm the bench opening and clearances before installation
Use the flange only for approved partially embedded installations
Maintain all required heater clearances from combustible materials
Do not modify the flange or heater
Do not use the flange as a support, shelf, or guard
Have your sauna builder or installer handle the bench cutout and flange placement if needed

The flange is a finish accessory. It does not replace required heater clearances, safety rails, ventilation requirements, or HUUM installation instructions.

Important Safety & Clearance Note

A partially embedded sauna heater installation requires careful planning. The heater must still be installed according to HUUM’s official clearances, bench opening requirements, airflow requirements, and safety guidelines.

The HUUM Flange HM helps finish the visible bench opening, but it does not make the heater safe to touch and does not eliminate required heater clearances. The heater, stones, and nearby metal surfaces can become extremely hot during use.

For best results, review the HUUM manual with your sauna builder and licensed electrician before finalizing the bench design.
