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.
That shared stand is the news. It's 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.
Sauna brands at Interbad
Interbad 2026 has 279 exhibitors registered. Thirty-five of them are filed under the sauna categories, and every one is in Hall 1:
- HUUM, Auroom, Leil Saunas, Haljas Houses and DWILD, stand 1C32 (Estonian Sauna Trust)
- Harvia Austria and EOS Saunatechnik, stand 1C54
- Klafs, stand 1J41
- IKI-Kiuas, stand 1B39
- Narvi, Mondex and Finnsauna, stand 1B51
- Sawo Nordic, stand 1B45, and Cariitti, stand 1B52
- Sauna Europe, stand 1B58, and Luxus-Saunat, stand 1C56
- Auroom Saunas SIA (the Latvian entity), stand 1D40
- Palmako, stand 1D20, and Pieksäwood, stand 1B41
- Poolstar, stand 1C18, moveo, stand 1C52, and devine wellness, stand 1G61
Two things stand out. Harvia and EOS share 1C54, which is what owning your competitor looks like on a floor plan. And the Finnish heater makers cluster in the 1B row while the Estonians take 1C, which is less an accident than a reflection of who books together.
For the North American side of the same buying cycle, compare Interbad with the International Builders' Show and Pool Spa Patio Expo, which runs in New Orleans six weeks later. Piscine Global in Lyon is the other European stop, that same November week.
