What people like

The heater is highly praised for its unique, aesthetically pleasing water drop design and robust stainless steel construction, originating from Estonia. Its large stone capacity is frequently cited as a key feature, contributing to a high-quality, soft, and long-lasting steam experience that is reminiscent of traditional Finnish saunas. Compatibility with the HUUM UKU control system, including Wi-Fi options for remote operation, is also a significant positive aspect. While it's designed for efficiency and even heat distribution, some users note that the heat-up time can be longer compared to some competitors due to its substantial stone mass.

Pros

  • Modern Design: Features an elegant, water-droplet inspired, and award-winning aesthetic that enhances any sauna's visual appeal.
  • Efficient Heating: Quickly reaches high temperatures, up to 230°F (110°C), providing an intense and enjoyable sauna experience.
  • Smart Controls: Offers convenient remote operation via a mobile application when paired with the UKU WiFi controller.
  • High Stone Capacity: Accommodates a large volume of sauna stones (around 122 lbs), ensuring long-lasting and soft steam production.
  • Durable Construction: Built with high-quality, often stainless steel, materials for reliability and extended lifespan.
  • Space-Saving: Wall-mounted and compact form factor makes it suitable for various sauna layouts, especially smaller ones.
  • Enhanced Safety: Newer models include an element separator and improved sauna rocks to mitigate overheating concerns.

Cons

  • Higher Cost: The product, along with its necessary accessories, can be a significant investment.
  • Controller Separate: The UKU WiFi controller, essential for smart functionalities, is not included and must be purchased separately.
  • Slow Heat-Up: The 4.5kW model may exhibit slower heat-up times in larger rooms, potentially exceeding two hours.
  • Stones Not Included: Sauna stones, which are crucial for operation, are typically sold separately.
