Nordic Heat.
Beautifully Formed.
Sculptural Estonian sauna heaters shaped around generous stone capacity, gentle steam, and intelligent UKU control.
Estonian sauna design Introducing HUUM
HUUM reimagines the electric sauna heater through the elemental language of stone, steel, and steam. Its open heater forms hold a generous volume of sauna stones, supporting softer warmth and a fuller steam experience.
Designed in Estonia, HUUM allows the heater to become part of the sauna’s architecture rather than equipment that needs to be hidden. The result feels organic, contemporary, and deeply connected to traditional sauna ritual.
Chosen with intention Why Between Living Chose HUUM
Stone-Led Warmth

Complete Heater Packages

One philosophy · Two forms
Choose the expression of heat that belongs in your sauna.
DROP brings a floating, organic presence to the wall. HIVE Mini creates a grounded, architectural centrepiece. Both are shaped around exposed stone, soft steam and compatible UKU control.
Wall-mounted · Organic · Sculptural
Meet the HUUM DROP.
Inspired by the shape of a water droplet, DROP brings generous exposed stone capacity into a compact wall-mounted form. It is especially well suited to thoughtfully designed home saunas where floor space matters and the heater remains part of the visual room.

Floor-standing · Grounded · Architectural
Meet the HIVE Mini.
HIVE Mini concentrates the visual strength and substantial stone capacity of HUUM’s cylindrical heater language into a refined floor-standing form. It suits saunas where the heater can become a grounded centrepiece rather than simply sitting at the edge.

Meet UKU.
UKU is HUUM’s external control system for managing sauna heat with quiet simplicity. Choose UKU Local for refined control from within the home, or UKU Wi-Fi when remote app access is part of the ritual.
Every Between Living HUUM heater package already includes a compatible control choice and sauna stones. These separate UKU listings are available for customers purchasing or replacing a control independently.

Already know your sauna size? Verify the heater before ordering.
Heater output should be selected according to the calculated volume of the sauna room, including adjustments for glass, tile, stone and other uninsulated surfaces. Use the estimator once you know the dimensions of your existing or planned sauna.
