About

Koti is a sauna built in its owners' back yard on a residential street in Milwaukie, open since June 2025. The outdoor cedar sauna sits beside two cold plunges, hot and cold outdoor showers, fire pits and a lawn. Shared sessions are co-ed and swimsuits are required.

Good to know

  • Cold plunge available on site: use it between rounds for the classic contrast cycle.
  • Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
  • Electric stove: quicker to bring up to temperature, easier to control, and what most urban bathhouses run.
  • Mixed sauna: men and women share the room, in every session or on set days.
  • Swimwear sauna: some or all sessions are taken in swimwear, so pack it.
  • Bookable as a private session: rent the room for your group rather than sharing with strangers.
