Highly recommend the "ultimate experience" if you have the time. From start to finish we felt pampered, cared for and liberated from the accumulated stress of life. The next day is when you really appreciate the experience, my nervous system was balanced and I felt like a new person who responds to life differently. Amazing effects! Treat yourself and someone you love to this truly unique experience. Thank you Osmosis!

Lovely spa! The cedar enzyme bath was very unique and left my skin feeling soft and renewed. The facial was also extremely nice and to my delight didn’t include any products with very strong scents. Worth driving all the way out there

The place was unique, in a small part of town, the customer service is good. It's pretty busy, so book in advance, we did a last minute book, all they had left was the cedar bath. So we'll have to come back and try the other services.
The cedar bath was a unique experience, like bathing in warm sawdust. The fragrant was nice, very calming atmosphere. However, next time, I would not do the bath by itself. I think it would be more affective with other services. Otherwise it's just an expensive relaxing sawdust bath.
