About
Othership's first US bathhouse is on West 20th Street in Flatiron. Sessions run as guided classes or quieter free-flow visits, moving between a large cedar sauna, eight ice baths and a fireside tea lounge. Swimsuits are worn throughout, and the changing stalls are not split by gender.
Good to know
- Cold plunge available on site: use it between rounds for the classic contrast cycle.
- Runs aufguss sessions: a guided löyly ritual where an attendant fans the steam around the room on a schedule.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
- 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.
