HUUM
An Estonian design-school challenge that became a global sauna brand.
HUUM was founded in 2014 by Siim Nellis, a third-generation Estonian stove-setter, after he challenged students at the Estonian Academy of Arts in 2011 to help design a more efficient electric sauna heater. The winning design became DROP, HUUM's founding product. Heaters are still assembled in Tartu, Estonia. RecoveryLux carries 39 active HUUM products: 25 heaters, 6 UKU digital controls, and 4 chimney kits — every heater and control pictured below with live pricing.
- 2014 — Founded by Siim Nellis
