Description
The Huum Drop is a wall-mounted electric sauna heater with a rounded, stone-clad shape instead of the usual box. The shape does real work: the stones wrap the element on all sides, so heat radiates out evenly instead of rising straight off a flat top. The design won a Red Dot Award.
Stone capacity
It holds 122 lb of stones, more than many wood-burning stoves. More stone mass means you can ladle on more water before the stones cool, for softer, longer-lasting steam.
Build and control
The body is stainless steel with industrial-grade heating elements. It is SGS listed, runs on 240V, and ships with the UKU digital controller. WiFi control is available as an option so you can preheat the room before you arrive.

Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- The Drop runs on 240V, so have a licensed electrician install it. Sizes: 4.5 kW up to 247 cu ft, 6 kW up to 353, 7.5 kW up to 424 and 9 kW up to 530.
- It holds 122 lb of stones wrapped around the element, so you can ladle on more water before the stones cool. Expect softer, longer-lasting steam than from a small box heater.
- It mounts on the wall, which keeps the floor clear in a smaller sauna. The UKU controller is included, and WiFi is an optional add-on for preheating from your phone.
- It carries a 30-day limited warranty against manufacturing defects and is SGS listed, with a stainless steel body and industrial-grade heating elements inside.
