612 Sauna Cooperative is a community-owned sauna organization founded in 2016 in the Twin Cities. Built around the idea of sauna as a shared civic practice, the cooperative is shaped by collective stewardship, volunteer labor, and mutual responsibility. Its central offering is the Forge, a volunteer-built mobile sauna with a 24-foot layout that combines a hot room, changing and cooling space, and storage for personal items. By bringing sauna experiences to locations across Minneapolis and the broader Twin Cities, the cooperative operates through a participatory model supported by members, community partners, and residency hosts. Respect, dignity, safety, and inclusivity are core principles of the organization’s community-centered environment.
