DROP Series 9.0kW Sauna Heater Package
This inspired HUUM DROP sauna heater package comes complete with the award-winning, compact DROP 9kW sauna heater, UKU control (WiFi optional), and sauna stones - everything you need to transform your sauna space into your dream sauna sanctity. The package has been combined for use in sauna rooms up to 460 cubic feet (CF).
Wood safety rail is sold separately.
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 a 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. Its 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.

Cancellations of customer orders
Custom or made to order products cannot be canceled or refunded as these products are put into production specifically for your order. These units are custom made to your specification or created once you order. Once you place your order they start building your unit. Your warranty will guarantee you a fully functional and operational product. If it is not clear whether your order is custom or made to order, please message or call us.
All sales are final for Custom made and Made-to-order products.
Refunds & Returns
If you need to exchange your product, you may do so. You, as the customer, are responsible for any shipping costs throughout any returns or exchange processes.
Not all orders are available for return once they have shipped. We order products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product.
Due to drastically increasing LTL/freight shipping costs, any outright returns will incur a 25% cancellation fee + return shipping costs. If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product.
Seller reserves the right to refuse to refund any deposit or payment, or cancel any payment due, and any owing until such time as Seller a) is in receipt of the goods b) has inspected the goods and c) in the Sellers discretion, has found the goods to be free of damage. All refunds will be provided within 5 business days once the product has been returned to the warehouse and inspected for damage.
We promise to do our best to get your order to you as soon as possible. We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelming demand on shipping, factory/warehouse and dock workers and so on).
