Product Overview

Designed for a More Finished Heater Installation

The HUUM Flange CS is used when a HUUM CLIFF or HUUM STEEL electric 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 CS is made from stainless steel and is designed to cover the rugged or uneven wooden cut 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 HUUM’s CLIFF and STEEL heaters. HUUM describes the Flange CS as an accessory for mounting CLIFF or STEEL heaters partly inside a sauna bench and notes that it creates a refined finished result around the cut opening.

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

Why You'll Love it!

Designed for HUUM CLIFF & STEEL Heaters

This accessory is specifically intended for HUUM CLIFF and HUUM STEEL electric sauna heaters. HUUM lists it as suitable for CLIFF/STEEL electric sauna heaters.

Stainless Steel Construction

Durable stainless steel construction pairs naturally with HUUM’s modern heater designs and stands up beautifully inside the sauna environment.

Ideal for Custom Sauna Benches

Use it when your CLIFF or STEEL 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 CS helps create a more intentional, professional-looking heater installation.

Supports an Integrated Heater Design

Embedding a heater can create a cleaner built-in look, especially in modern sauna interiors where the heater is designed to feel like part of the architecture rather than an afterthought.

Installation Guidance

Plan the Heater Opening Before You Build

The Flange CS is intended for sauna designs where the heater is partially recessed into a bench or platform. Because this affects the heater opening, bench construction, heater placement, and required clearances, it should be planned before final bench construction whenever possible.

When embedding a compatible CLIFF or STEEL heater:

Confirm your heater model compatibility.
Follow the official HUUM heater manual.
Maintain all required safety clearances.
Confirm bench-opening dimensions before cutting.
Make sure at least 21.7" of the heater protrudes above the bench surface.
Work with a qualified sauna builder and licensed electrician when needed.

The Flange CS is a finishing accessory; it does not replace required heater clearances or proper installation planning.
