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

Our intimate space provides a restful place to escape from daily routines. Our communal tub is 104 degrees and our other amenities include: a redwood cedar 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.

We invite people to be social but respectful. Please feel free to talk softly with your friends and fellow bather. We are an intimate space and want everyone to enjoy their time with us.



One hour and 45 minutes: $35
