Hot Tubs

We have modeled our bathing experience after the great hot spring onsen of Japan. There are two public hot tubs with sauna and cold plunge--one for mixed bathing and one for women only. We also have private tub environments. Premium hot tubs include saunas and other amenities. Spa suites are completely self-contained with hot tubs, saunas, cooling berths, and your own private changing room and showers. Hot tub water is maintained at 104-106 degrees F., cold plunges are around 55 degrees F., saunas average 180 degrees F.

 We can reduce the temperature in Shoji to 99 degrees if a reservation is made in advance.


'I received a gift certificate for a private hot tub -- it was the most wonderful experience in my whole life. We were surrounded by snow and it was late one evening and the we could see the moon and the stars. I'm recommending Ten Thousand Waves to all my friends. I also had a massage and it was heaven.'

'I've been going to Ten Thousand Waves since I was six months old. Ten Thousand Waves will have me returning for the rest of my life. Thank you for such excellent service.'

'Your beautiful facility totally met, and far exceeded, my expectations. Everything was just perfect. I simply did not want to leave such a magical haven. AHHHHH... '
