Huum Sauna Heaters: Design Meets Performance
Huum is an Estonian sauna heater company that has quickly earned a reputation for making some of the most beautifully designed heaters on the market. While Harvia is the established giant, Huum is the brand that architects, designers, and sauna enthusiasts who care about aesthetics tend to gravitate toward.
But Huum isn't just about looks. These heaters produce excellent steam and come with some of the best smart controls available in the sauna industry.

What Sets Huum Apart
- Design: Huum heaters look like they belong in a design museum. Clean lines, minimal profiles, and thoughtful forms that blend into modern sauna interiors
- UKU WiFi Controller: Huum's signature control system lets you start, monitor, and control your sauna from your phone. Preheat your sauna on the drive home so it's ready when you walk in
- Estonian heritage: Estonia has a deep sauna culture similar to Finland's. Huum products are designed by people who grew up using saunas regularly
- Rock-forward design: Many Huum models are designed to be almost entirely covered in rocks, maximizing thermal mass and steam quality
Popular Huum Models
Huum Drop
The Drop is Huum's most recognizable heater - a teardrop-shaped unit that's almost entirely covered in stones. It's wall-mounted, available in 4.5-9 kW sizes, and produces excellent loyly. The organic shape is a conversation starter in any sauna.
Huum Hive
The Hive is a floor-standing cylindrical heater that holds a massive amount of rocks (up to 440 pounds in the largest version). It's designed for bigger saunas and produces the kind of deep, sustained steam that traditional sauna enthusiasts love. Available in 12-18 kW sizes, it's a serious heater for serious sauna builders.
Huum Core
A more compact, wall-mounted option for smaller saunas. The Core delivers Huum's quality and smart controls in a more accessible package. Available in 6-10.5 kW sizes.
Huum Steel
Huum's most affordable and straightforward model. It's a clean, minimalist wall-mounted heater that still offers the UKU control system. Good for builders who want Huum controls without the premium price of the Drop or Hive.
The UKU Controller
The UKU is the standout feature that ties Huum's lineup together. Features include:
- WiFi connectivity and smartphone app control
- Remote preheat - start your sauna from anywhere
- Temperature and timer settings from your phone
- Usage tracking and statistics
- Over-the-air firmware updates
The UKU comes in a glass-front wall panel version and an in-app-only version. Both connect to Huum's cloud for remote access.
