Sauna & Cold Plunge Studio
Tiny footprint. Premium pricing. Members who never quit.
Sauna and cold plunge studios offer private and semi-private sessions in Finnish dry saunas, infrared saunas, and cold water plunge pools. Driven by biohackers, athletes, and longevity culture, sauna has crossed from Nordic niche to mainstream wellness trend. These studios operate with a very small footprint (1,500-3,000 sq ft), 2-4 sauna rooms, and 2-3 plunge pools. Memberships at $150-$250/month produce extremely high retention — once someone builds a daily sauna habit, they don't cancel. Revenue per square foot rivals luxury gyms with a fraction of the equipment maintenance headache and none of the treadmill upkeep.

How It Works
Revenue comes from day passes ($30-$65/session), monthly memberships ($150-$250/month), private group bookings ($200-$500/event), and retail add-ons (towels, sauna hats, eucalyptus). Memberships are the core driver — 200 active members at $185/month is $444K ARR from memberships alone. The studio runs with 1-2 staff per shift for towel service and booking management. Professional infrared saunas cost $8,000-$20,000 each; cold plunge tanks run $5,000-$20,000. The major startup cost is electrical, plumbing, and ventilation build-out.
