HUUM has released App 4.0, a completely new version of its sauna control application built from the ground up. The Estonian heater manufacturer told SaunaNews it rebuilt the entire server infrastructure, delivering 3x faster communication between the app and the UKU control panel. Multi-sauna management, smarter booking, and a full dark theme round out what HUUM calls its biggest update yet.
Haljas Houses has won its third Red Dot Design Award with the Hele Nano and Tarantula. The SaunaNews team has used the Nano firsthand, and its no-crane delivery model is a genuine differentiator in the US prebuilt market.
Estonia's 34+ sauna manufacturers, led by Thermory, HUUM, and Saunum Group, have turned a tiny Baltic nation into one of the world's most important sauna production hubs. Here's why it matters for American buyers.
On June 27, 2025, Underwriters Laboratories published ANSI/UL 60335-2-53, the first U.S. adoption of the international sauna heater safety standard. It is the most significant regulatory shift in North American sauna history. Here is what it changes, what it doesn't, and why your building inspector might not care yet.

With China tariffs at 145% and a 15% surcharge on European imports, we mapped which sauna brands carry the most tariff exposure. Sauna360, whose Finnleo-branded prefab kits are primarily manufactured in China, faces the steepest cost pressure of any major brand.
HUUM has standardized its internal air tunnel technology across the full HIVE heater line, a quiet but significant engineering upgrade. The air tunnel improves airflow through the stone chamber, reduces heat-up time, and shields heating elements from direct stone contact, extending their lifespan.
