Product Overview

Designed for a More Finished HIVE Installation

The HUUM Flange H is used when a HUUM HIVE sauna heater is installed partially inside a sauna bench or platform. This type of installation can create a beautiful, integrated heater area, but it also requires a clean way to finish the wood opening around the heater.

The Flange H is made from stainless steel and is designed to cover the cut wooden edges around the embedded heater opening. The result is a smoother, more refined finish that looks intentional, professional, and aligned with the premium design of the HIVE heater.

For sauna builders, homeowners, and designers creating a more architectural sauna interior, the Flange H helps elevate the final presentation while supporting a cleaner installation detail.

Why You'll Love it!

Creates a Cleaner Finished Look

The Flange H covers rough or exposed wood edges around the heater opening, creating a more polished built-in appearance.

Designed for HUUM HIVE Heaters

This accessory is specifically intended for use with HUUM HIVE electric sauna heaters, not the HIVE Mini series.

Stainless Steel Construction

Durable stainless steel construction pairs naturally with the HIVE heater’s modern metal design.

Ideal for Custom Sauna Benches

Use it when your HIVE heater will be partially embedded into a bench, platform, or custom sauna surround.

Refined Architectural Detail

For high-end sauna builds, small finishing details matter. The Flange H helps create a more intentional and professional heater installation.

Compatibility

Designed for HUUM HIVE Series Heaters
