SaunaNews coverage from the show

HUUM at 1C32, and four neighbors

HUUM is in Hall 1 at stand 1C32, and it calls Stuttgart its biggest event of the year. It isn't there alone. The official directory puts four other Estonian companies on the same stand number: Auroom, Leil Saunas, Haljas Houses, and DWILD.

The shared stand is the international debut of the Estonian Sauna Trust, a selective alliance registered as the nonprofit Eesti Sauna Liit MTÜ, with HUUM, Auroom, Leil and DWILD as founding members. The pitch is a quality mark: a way for buyers and spa operators to identify Estonian manufacturers who stand behind their products and technical support. Membership is by selection.

"Estonia has quietly become one of the world's great sauna nations, and it's time the world recognises it at a glance," HUUM CEO Mihkel Ilp said in the launch release. Our launch-day report profiles all four founders, from HUUM's heaters to Auroom's and DWILD's modular commercial saunas.

HUUM used opening day to unveil three new heaters. CORE Pro is a 12 to 21 kW heater for spas, hotels and public saunas, with its heating elements in a service drawer, and two can be paired side by side for up to 42 kW. KLINT and KLINT Solo are cylindrical floor heaters carrying about 230 pounds of stones; KLINT Solo builds its controls into the heater. Our coverage of the bench-embedded CORE and the App 4.0 rebuild is the background, and the HUUM company profile tracks the rest.
