Quiet hours in the bath are from 11am – 1pm on weekdays. Visiting us during these hours means taking time to relax and reflect without conversation. This time is reserved for those guests who are taking time for introspection without talking. We will remind everyone of our quiet hours before entering the communal bath. On evenings and weekends 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, please visit us during the time that best suits you.

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.



First hour and 45 minutes: $30
Every hour after: $10
