About
Onsen is a family-run hot tub and sauna rental on Garden Avenue in Eugene, in business since 1981. Its private sauna is booked by the hour, alone or paired with an open-sky hot tub room. Bookings need at least two people under Oregon law.
Good to know
- Bookable as a private session: rent the room for your group rather than sharing with strangers.
- Hot tub on site: adds a warm-water option between the sauna and the cold plunge for a longer cycle.
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
