New sauna business in Moss: Tronvik Sauna Club
New association registered in Moss
Tronvik Sauna Club has been registered in the Norwegian Register of Business Enterprises with organisation number 937092652 and address Morenen 48 in Moss municipality. The association was founded on 27 December 2025 and registered on 3 February 2026. According to its own stated purpose, it will “promote sauna culture and mental health”. The association is not registered in the Register of Voluntary Organisations and is not VAT registered.
What the register says
The legal form is association/club/body. This means the business is organised as a membership association, typically run on a voluntary basis with a board elected by its members, as opposed to a limited company operated commercially. The register lists no employees, no website and no information about what the association actually plans to do. The industry code is “Activities of other membership organisations”. Neither bankruptcy nor winding-up is registered.
The sauna offering in the area
Three saunas in Moss are already listed in our overview: Moss folkebadstue, Moss Kurbadstue and ROA Badstue Moss. The most common types in the area are wood-fired (2), indoor (1) and floating (1). In the Eastern Norway region, 174 saunas are registered, and our catalogue lists 599 in total. The new association is therefore entering an area that already has an established sauna offering, but the register says nothing about what Tronvik Sauna Club might add.
What we do not know yet
The register does not state when – or whether – the association plans to open a sauna, where it would be located, what prices would apply, or what members would be offered. A registration means the entity has been established, not that a sauna has been built or opened. We also have no information about membership numbers or operations.
