The technicians for both the cedar bath and facial were amazing. However I was a little disappointed in care outside of that. Lack of directions, no lotion after the shower and the person I asked told me there is lotion in that room. I looked and there was not. Didn’t feel pampered which is an expectation at a place like this. May not return.

What a wonderful way to spend my Birthday.
I chose a Swedish massage with a scalp massage, with Diana. I checked in, I got a tea and toured the Japanese gardens. It was so peaceful. I sat in the meditation area overlooking the beautiful koi pond. I chose a
Heated Pagoda for my massage. It was so peaceful. My massage was amazing . And so relaxing. I cannot wait to go back.

I had an absolutely wonderful experience at Osmosis Day Spa Sanctuary. The moment I arrived, I felt as if I had stepped into a peaceful retreat tucked away from the rest of the world. The staff was incredibly welcoming, attentive, and genuinely focused on creating a calming, personalized experience.
The atmosphere is serene and beautifully designed — from the stunning Zen gardens to the soothing treatment rooms. My service was exceptional, deeply relaxing, and thoughtfully carried out with so much care. I left feeling refreshed, restored, and completely at peace.
Osmosis truly lives up to its name as a sanctuary, and I can’t recommend it enough to anyone looking for a mindful, rejuvenating escape in California. I’m already planning my next visit!

This was my first visit to Osmosis and it was nothing short of incredible! From the moment you walk from your car to the front door, you are invited to experience the serenity and peace of this lovely sanctuary. Then, from the person who greeted me at the front desk and checked me in, to the person who directed me to my robe and locker room, and finally to the person who gave me one of the most incredible massages and the person who gave me one of the most luscious facials ~ WOW! In between, I took a short walk in the fantastically beautiful and well-manicured Meditation Garden ~ which included a small pond filled with beautiful coy fish. Every detail is so well-thought out and truly lovely.

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!
