Price:

$4,115.00

The HUUM HIVE is the powerhouse of the HUUM lineup — a larger, floor-standing version of the popular Hive Mini, built specifically for spacious saunas, spas, and gyms. Designed for performance and endurance, the HIVE series is available in 12 kW, 15 kW, and 18 kW models, perfectly suited for large sauna rooms.

Capable of holding up to 17 boxes of HUUM stones (approximately 250 kg / 551 lb), this heater delivers impressive heat retention and rich steam generation. The massive stone capacity ensures long-lasting, even heat distribution — ideal for extended sauna sessions.

Beyond its size and power, the HIVE shares the same modern design and superior craftsmanship as the Hive Mini. It reaches temperatures up to 110 °C, supports Wi-Fi control options via the HUUM app, and maintains the brand’s signature clean, minimalist aesthetic.

The generous stone storage isn’t just for looks — it enhances the sauna’s ability to produce smooth, consistent heat and rich steam. Pour water over the stones to experience a soft, even warmth that envelops the entire sauna room.

In short, the HUUM HIVE combines raw heating power, elegant design, and advanced control features to deliver an exceptional sauna experience for larger commercial or residential installations.

    The local and Wi-Fi sauna controls are essentially the same in terms of hardware and functionality. The key difference is that the Wi-Fi version includes an ID for connecting to the HUUM mobile app (Apple or Google Play). This feature allows you to remotely activate your sauna, enabling you to heat it up in advance, whether you're on your way home or just finishing a workout. It's designed to enhance convenience, ensuring your sauna is ready when you are.
