About
W Sauna is a private contrast therapy studio in Kakaʻako, Honolulu, which opened in July 2026. Each booking gets its own open-air lounge with a barrel sauna, a cold plunge tub and a shower. Towels and bath amenities are provided, and guests bring a swimsuit.
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.
- Bookable as a private session: rent the room for your group rather than sharing with strangers.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
