 Sauna and Soaking pool at Onsen

The bathing ritual in Japan is deeply ingrained in their society, with the idea that a daily soak will cleanse and restore body and soul. 

Inspired by Japanese bathing culture, our intimate space provides a restful environment to escape from daily routines. We are more akin to a Japanese sento, where neighbors soak together, chat about what's going on in their lives and take space for themselves to enjoy the restorative quality of soaking in a hot water bath. We invite people to be social but respectful. Please feel free to talk with your friends and fellow bather but thoughtful of others enjoying the space along with you. Every visit will be different because of the social nature of our experience, weekends are busy and more vibrant while Women's and Men's hours can feel more serene. Our sento is intimate and we want everyone to enjoy their time with us.

Our space has a 104 degree communal tub and our other amenities include: a redwood sauna, steam room, custom overhead cold plunge and western style showers. Complimentary bath products and hot tea are included in the soaking experience. We also provide a locker, towel, robe and compostable bag for your wet swim suit.
