HUUM DROP 4.5STU Sauna Heater Package – Small Sauna, Big Elegance
Bring modern elegance and exceptional performance to compact sauna spaces with the HUUM DROP 4.5STU Package. This all-inclusive set features the award-winning DROP 4.5kW wall-mounted electric sauna heater, your choice of UKU Local or Wi-Fi control system, and 132 lbs of premium olivine sauna stones. Ideal for sauna rooms between 106 and 247 cubic feet, this package delivers soft, consistent heat in a sleek, space-saving design.
Inspired by the pure shape of a water droplet, the HUUM DROP heater adds a graceful aesthetic to traditional sauna interiors. Despite its compact size, the DROP boasts an impressive 122 lb stone capacity—surpassing many larger wood-burning models—and ensures long-lasting steam and mild, enveloping heat.
