Great massage but zero stars for a “spa” experience. I checked in and was told to wait out front. I was not welcomed in or given a tour or a robe. If there’s a zen garden, no one told me about it. I happened to see a changing room with robes hanging up on my way out. I had a 70 min massage and 15 min scalp add on and thought I would be relaxing here but it was very transactional.

It is always a gift to the body & soul to be at Osmosis. It is so peaceful and calming. Dieter took exceptional care of me - he is compassionate, attentive and a skilled professional. Thank you for a magical morning.

We did the cedar soak and couples message and it was an absolute tranquil time. The cedar bath was a gradual build of heat broken up by lavender cold towels. Our masseuse were attentive to our sensitivities. Even if you go in the rain make it out to the meditation garden; it is absolutely stunning and peaceful!

This was my first visit and it won’t be my last. The care and beauty of the place and people, the services and products were all really worth the drive in the rain. I’m very grateful to have found this place and highly recommend it.

Had a fantastic time for a Christmas given to me and my partner. The front staff was amazing and tended our every need before we knew we needed it. Our couples massage was extremely peaceful with Kumi and Elraya. We left feeling refreshed and Elraya was amazing working out the knots and tension I had all over. I also had a facial with Robin and my skin is still shining even the next day. My partner did the Cedar bath while I did my facial and he said all the tension was gone from him and that all the bath attendants were amazing at anticipating his needs for water and cool towels. We ended our time with tea in the meditation garden and could have spent all evening and night by the water. The entire establishment is cozy, clean and filled with amazing professionals from the management, the front staff, attendants and the providers giving services. I cannot wait to go back for another day of pure relaxation.
