Description

The HUUM DROP 9STU PKG features all the necessities to give your sauna space a touch of elegance.

The heart of this all-inclusive sauna heater package is the award-winning DROP 9.0 kW electric sauna heater engineered for spaces up to 530 cubic feet (CF). Choose between the advanced UKU Local digital sauna control, or the added convenience of an UKU Wi-Fi control package which allows you to preheat your sauna from anywhere with your mobile device.

The design of the HUUM DROP sauna heater is inspired by the purest element in nature – a drop of water. Its rounded design softens and compliments the angular interior of a classic sauna, giving it a touch of elegance. But DROP isn’t only about the looks. This compact wall-mounted heater can actually fit up to 122 lbs of stones, exceeding most wood-burning stoves and guaranteeing long-lasting steam.

Winner of the prestigious Red Dot Award in Europe for design, the HUUM DROP combines sculptural beauty with engineering excellence. It's exceptionally large rock capacity allows the sauna bather to ladle more water onto the stones for a more intense bathing experience while creating a more consistent, soft high heat. 

The available Wi-Fi control lets you preheat your sauna from anywhere. For bathers who want the absolute best sauna heater.

What people like

This wall-mounted heater is highly celebrated for its distinctive, award-winning aesthetic that serves as a focal point in any modern sauna. Reviewers consistently praise the exceptional quality of steam produced by its massive stone capacity, which ensures a soft, consistent, and long-lasting heat. The integration of smart mobile controls allows for effortless remote operation, while the compact footprint maximizes interior space for a more comfortable seating arrangement. It is frequently described as a premium solution that perfectly balances elegant craftsmanship with traditional performance.

Pros

  • Stunning Modern Design: The unique water-drop shape is frequently cited as the most visually appealing heater on the market, enhancing the overall sauna ambiance.
  • High Stone Capacity: By holding up to 122 pounds of stones, the unit provides a superior and more authentic steam experience compared to traditional heaters.
  • Smart App Integration: Users value the ability to preheat the sauna remotely through a mobile app, providing modern convenience and scheduling flexibility.
  • Space-Saving Build: The wall-mounted design allows for more floor space and versatile bench configurations in small to medium-sized rooms.

Cons

  • Complex Stone Loading: Users report that the large volume of stones requires meticulous placement to ensure proper airflow and to prevent damage to the internal components.
  • Sensitive Heating Elements: Some reviewers noted that the exposed heating elements can be delicate and may have a shorter lifespan if the stones are not packed correctly.
  • Technical Installation Requirements: The wiring and pairing with specific controllers are described as complex, often necessitating professional electrical assistance for a successful setup.
  • Slower Heat-up Time: Due to the massive amount of thermal mass provided by the stones, it can take longer to reach peak temperatures compared to heaters with smaller stone capacities.
