Osmosis Day Spa Sanctuary

I was drawn in by Osmosis’ pretty website that promises a luxurious, relaxing day spa. I wasn’t 100% about the «enzyme bath» but again, lured in by fancy phrases like «toxins», I convinced my fiancé to give it a try. We decided to go and check it out on our honeymoon. Upon arrival, we pulled up at a pagoda style house, kind of ramshackle with a sliding glass door and a fountain off to the side. We were given some tea that a woman said she had «added digestive enzymes» to, to «help us sweat». Yeah, no thanks. We were then led into the enzyme bath, essentially a warm giant sandbox full of fermenting wood. If you think that might smell bad, well, you’re correct! The stench was intense. We were buried up to our necks and I could feel it seeping into my hair. We were left in this disgusting concoction for 20 minutes. When the woman came back, I asked if the tub was sanitized, or if the wood was replenished after every guest’s «bath». When she told me they recycled the tub and didn’t change it for WEEKS, I almost barfed right then and there.
They told us to brush ourselves off, so we did, and shared the shower in the room. Trying not to think about the prospect of having just bathed in 23 other people’s body fungus, we washed ourselves 10 times with the soap provided. However, there would never be enough soap because the smell of the fermenting wood stayed with us for days. And don’t try and tell me it was «the toxins», a phrase I became very familiar with throughout the day.
Our underwear, completely ruined from the smell of the wood shavings, and completely wet from the shower, had to be thrown away and never spoken of again.
We were led upstairs to have a massage, which was actually very nice. At one point, when my head was in the massage table headrest, my nose clogged up. When I told my massage therapist, she said it was «the toxins» leaving my body. Yeah, no. Actually it was because I take afrin more than I should, and I had missed my dose that day.
We were told to enjoy the «zen garden» outside, so we took a short stroll to a garden with a murky pond, and a space to meditate. It was kind of nice, but the location of the garden is directly parallel to one of the spa’s parking lots, which the employees use. We could clearly see the coming and goings of whomever had to pick up the next shift, do some construction, etc.
The next time I enjoy a day spa, I’ll make sure to visit first, or stick to something a little more sanitized. Also, the prices! Holy cannoli! You would think you were at the Four Seasons in Santa Barbara, except you’re totally, totally not.
I gave two stars because the massage was great.

Today my husband and I enjoyed an amazingly relaxing day at beautiful Osmosis. We were welcomed by the lovely receptionist who offered us tea to start. We arrived early for our appointments so we browsed the wonderful gift shop where I found a unique gift for a friend. The gift shop is so well-​rounded and has so many great products and gifts to offer. We then were escorted back to the changing rooms where we changed into cozy robes and made our way upstairs for our couples massage. My massage therapist name was Crystal and my husband had Natalie. Both therapists were wonderful. We both commented after how nice it was to have the treatments so customized to our individual specific body needs. After our massages we relaxed for a few minutes before we were greeted by our amazing estheticians to begin our facials. My esthetician was Heather and my husband had Azja. The products that they use are so amazing and they smell so good. The treatment was so relaxing and soothing. The product choice was personalized to my skin needs and concerns. I felt like each product chosen was thought out and chosen specifically for my personal needs. My esthetician was highly knowledgeable about product ingredients and explained to me the benefits of each products. I enjoyed every minute. My facial included a wonderful foot and arm massage that was just icing on the cake after having such wonderful products. We were hoping to have the enzyme baths today as well but unfortunately they were booked up when I made the reservation a couple of weeks ago. Note to self: book in advance. ;). I’ve had the enzyme baths many times before and it certainly isn’t something you want to miss. After our massages and facials we toured the beautifully maintained zen gardens. What a beautiful, tranquil and serene place. I’ve traveled around the world many times and enjoyed many spa treatments during my travels but it’s hard to compete with Osmosis. They have mastered the art of relaxation. Well job Osmosis, I will most definitely be back. Thank you for a beautiful day with my husband, we thoroughly enjoyed every moment we spent there.

Had a great massage w Consuelo and a facial with Azja. Out of this world!!! Not to mention the enzyme bath. HEAVEN. Can’t wait to go back!!!

I’ve been coming to Osmosis for years and I’m sad to say that the experience here is nothing like it used to be. The facility is not meant to accommodate all of the people that it books and because of this, the place is extremely noisy and the zen like relaxing feeling is anywhere but there.
I recently returned to use a deep tissue credit I was given from my last deep tissue massage visit (because that massage was so horrible) as well as a facial. The deep tissue massage was much better than my last experience; however, the facial did more damage than good. I had to stop the sales pitch infused facial because the essential oil towel wrap started to chemically burn my face and eye lids. After a few minutes of excruciating pain, I was able to stop the burn on my face but my eyelids continued to burn. After I stopped the facial I literally had to keep cold compresses on my eyelids for at least 20 minutes in order to lessen the burn.
The skin on my eyelids is now raw, super red, and extremely inflamed. The esthetician profusely apologized saying that this oil wrap can burn a little bit but nothing like I was describing. Yea, I don’t think any «natural, essential oil» product should feel remotely close to a chemical/​acid burn on your face, let alone on the delicate skin surrounding your eyeballs.
After apologizing 30 times, she left the room to check and make sure they would «comp» the 15 minutes of the facial I was able to complete… really, check to see if they would comp my disaster of a facial? Wow! Great news is everyone at the front could see the damage done to my eyelids so they were happy to not charge me.
Needless to say, I am no longer a fan of this place and I will never be coming back. I’ve tried now a few times and each visit just keeps getting worse.

The massage here was great but unfortunately I tried the enzyme bath and got an awful rash!
Turned out to be pseudomonas folliculitis which requires an antibiotic cream.
Massage great. Staff great. Sanitation of the bath… very questionable.

I thought I was signing up for a couple’s package but was not able to do the cedar bath due to health issue, so I emailed them back and forth and they removed the bath from the package, but I didn’t realize they removed everything else that came with the package as well and just kept the massage! For that alone, given the atmosphere of the place, the low temperature of the massage room, and the sub-​par quality of the massage, it was extremely over priced. The room was cold, the heated pad only started working towards the end so I wasn’t able to enjoy my massage. The place was not very cozy, most of it looks like a normal house, the carpet, bathrooms, etc. are very standard. The dressing room is very small and the concierge opened the door to welcome new people when I was still finishing getting ready. After our massage we were told that we could ‘hang out’ somewhere, but there was not a place to do so, we were never shown to a meditation room or area. There were people already lined up for another massage so we were quickly ushered out and rudely asked to be quiet even tho the therapists were still talking to us. So we went downstairs, got changed and just left. I cannot speak for the cedar bath, as I didn’t try it, but given my experience with the rest of the place and the price, I will not come back to Osmosis.

About 14 years ago, an ex-​boy friend brought me here to celebrate my birthday. Since then, I’ve been here 6 times, brought my new boyfriend, now husband and just recently brought my son and his wife here. It’s such a special place and special treatment. The garden, the tea, the sawdust bath, massages and their extensive walking path along the creek makes for a nice retreat. When the weather is warmer, I enjoy getting a massage in one of the outdoor pagoda.

I feel like I got the gag gift. I’m extremely frustrated by my experience at Osmosis — not the outcome one wants from a trip to a spa. I gave it 2 stars because the meditation garden is gorgeous and serene. I couldn’t even fully enjoy that, because people busily and noisily walked by.
When I went into the changing room, I noted a sign indicating that ALL robes are XL «for your comfort.» Really? Because I’m not comfortable in a flimsy sheet robe that’s two feet too long for me. Moreover, it had a big torn hole in it. I chose another. Same. Their flimsy robes are not only flimsy and uncomfortably large, they’re also holey.
Worst yet, for a hefty $ 139 for the massage, I left more stressed than I was upon arrival. My masseuse was abrupt, rushed, and wreaked of nervous energy. At one point, when I asked for water, she put her hand out as if to rush me to return the cup to her. Then, because I’d pushed the sheets down for a drink, I was corrected: «You need to keep yourself covered please.» I felt like I was back in school, being reprimanded, and I could never find a place in the same hemisphere as zen. Plus, I’d have had to pay $ 10 extra for aromatherapy. That’s flat-​out ridiculous. Most of the massages I’ve gotten in the past had a nice scent in the room already.
I did receive seemingly sincere apologies from the front desk staff after voicing my concerns, but that does not compensate for the lousy service. Osmosis does not live up to its reputation. Do yourself a favor and go somewhere else that does, or to a to-​be-​discovered massage therapist and/​or spa. There’s certainly no shortage in Sonoma County. And you’ll find a better price too.

Top notch GREEN BIZ full of healing (staff, services, meditation pathways). Went yesterday for my birthday on my actual birthday! The cedar enzyme bath followed by a Swedish massage made me feel relaxed, integrated and nurtured. So much beauty and openness to contemplate and reconnect with self and restore my own sense of integrity and purpose in the world. Next time will go for a bath that had been fermenting longer (more heat!) since mine was just 4 days going (gentle and still effective though)! Highly recommend this secret spot.

I love this place for the cedar enzyme baths. The massages are ok, the atmosphere is amazing and serene. But really I go for the only place you can get a cedar enzyme bath in California! This place is very over priced, if you’re looking for an inexpensive spa, do not come here. My fiancé and I got 2 cedar baths (1 each) and we each received a basic 75 minute massage. The cost was $ 470! Kind of hard to swallow as I can get a 60 minute massage for 40 $ around the corner from my house! That being said, the staff is serene, they play their parts well and have good customer service. A great place to get away from it all and just be. We will come here again within the next couple of years. Would be an awesome pre-​marital spa day place.

The private meditation garden is lovely, there’s just too little time allotted for you to spend there. Everything moves right along during this experience (because there is someone booked right behind you!!!) At $ 89-​$ 99 dollars per person NOT including gratuity, for what amounts to only about 10 mins in the (private) meditation garden prior to the bath, and 15 mins in the bath itself, this is a VERY pricey experience. There is also a nickel and dime nature to the costs for massage– a regular swedish massage is one price, deeper work is more, and the deepest tissue massage is more yet – really? Never seen this before at ANY spa ever, where one gets the massage they want and the price is the same.

Such a beautiful spa and a unique, relaxing experience!
My boyfriend brought me here for a surprise day trip — we took a cedar enzyme bath followed by a couples magnate.
We loved all of the outdoor spaces, from the meditation garden to the little garden outside of the room you sip tea in before your bath. You can tell they put a lot of thought into how they designed each part of the garden. It’s gorgeous!
The cedar enzyme bath was amazing too. It’s like climbing into a grownup sandbox full of fancy, warm, fermented wood shavings. After your tea in the waiting room, you climb into the box and are covered in fermenting cedar mulch and zen out for 20 minutes.
We were mighty glad our bath specialist stopped by with cold towels every 5 minutes too — it gets hot in there! An amazing, unique experience though. Highly recommend it for spa lovers, anyone who likes unique and unusual experiences, or fans of Japanese culture.

We went to Osmosis Day Spa to wrap up my bachelorette weekend and couldn’t have made a better choice! We arrived early for our appointments and were invited to walk through the meditation garden until our services could begin. The garden was beautiful and peaceful and I could have spent all day there with a book and been a happy girl.
When our services were ready, we were given comfy robes and brought into a private tea garden to sip a warming tea before our cedar enzyme bath. We only did the foot baths, and honestly I’m glad, it was SUPER warm in the cedar bath rooms and I’m still a little weirded out by the idea of being covered it in but I do have to admit that my feet felt amazing and wonderfully soft and I might be open to fully submerging in the future.
I had a pagoda massage, I would recommend going with a normal massage instead, the pagodas are much more enclosed than I was expecting and a normal massage room would have served just as well. My masseuse was fantastic, using acupressure techniques and even giving me some tips to take home to avoid tension building up in the future.
Last was the field of hammocks. I was a little disappointed because I thought a field would be more than 6, but rocking and breathing into your relaxing day really helped to create a nice buffer before going out into the real world again. There were some flies in this area that made relaxing a little difficult and the amount of time they gave you felt long to me.
Overall, this was a perfect ending to the weekend. The staff was amazing and anticipated every need before you could think to ask. I would highly recommend it to anyone looking for a relaxing experience.

Very relaxing place, and I call it my «magical place» as I have a lot of quiet time/​self exploration there. The massage I got was amazing.

I felt really good, different then ever before, even the day after, from the the enzyme bath. It was a gift card i was given as a maid of honor gift that prompted me to go there, and i am so glad she gave that as the gift. It was really unique and special, and i will definitely go back!

I go to Osmosis about every six weeks, and have done the enzyme bath four or five times. It’s as good as you’ve heard. I also love the hammock garden with the hemi-​sync music, and the Osmosis boxed lunches (which you can request in advance) are nutritious and delicious. The grounds — including the meditation garden and pond– are lovely, and in general this is a peaceful and beautiful sanctuary. But that’s not why I’m here.
I want to write specifically about the therapist Kumi, to whom I’ve regularly been going for reiki, reflexology, and massage for more than two years. She is an absolute gem, and truly gifted at bodywork. I don’t think she’d use this terminology because she’s very humble, but she’s a body intuitive. She knows exactly where to go to heal whatever is causing you pain. The day after a reiki session with her, I’m in a fog as my body recalibrates and rebalances energy. But the day after that, I’m a new person. She’s helped me immensely with several serious issues: atrial fibrillation (heart arrhythmia), hip dysplasia, SI-​joint injury and corresponding sciatica, migraines, and more. I refer to my appointments with her as my «scheduled maintenance.» And now that I’ve started peri-​menopause, she’s helped me with hormonal issues too. Not to mention she’s just an incredible human being. If you plan to get reiki, reflexology, or even massage at Osmosis, and don’t know whom to request, ask for Kumi! You’ll be glad you did.
Osmosis is worth the drive from wherever you live.

This place is gorgeous, calming, beautifully landscaped, with the sounds of water and a beautiful, private view in the tea room where you wait to be taken back to the Cedar Enzyme Bath. The tea was lovely, and the cedar bath was very unique. Hot, relaxing, very different. I felt «purified» afterward, maybe even a little dizzy. :)
The shower afterward felt great, and the sound therapy was a bit strange and unexpected but very relaxing; although I did have to move the headphones up away from my ears a bit as it was just a tad too loud. However, I was happy to have the opportunity to lie back and semi-​sleep after the heat of the enzyme bath. In fact, my skin has felt dry and unhydrated since I had a baby six months ago and have been breastfeeding, and for the first time since childbirth, my skin felt glowing and healthy and more like it used to be; so that was a significant effect I noticed.
To be honest, I loved the experience and would consider it again if it were less expensive. For $ 100, I’d rather get a deep-​tissue massage for an hour rather than sit in hot cedar chips for 20 minutes. If it were closer to $ 40 or $ 50 per visit, then I would go again. And I would definitely consider going here for a massage in the future.

A gorgeous, high-​end place like this would normally be beyond my not-​very-​Zen budget. But this beautifully landscaped, full-​service spa was running $ 199 September special for the Cedar Enzyme Bath plus a 75-​minute massage in the outdoor pagoda. (The regular price would’ve been $ 259.)
The cedar «bath» is quite the novelty. You’re sitting in a giant tub for two in what looks and smells like hot cedar mulch. Nothing liquid about this experience at all. It supposed to be good for circulation and pulling out impurities, etc. Whatever, it was interesting.
The bath comes with a smiling attendant who served us lovely restorative tea. She also avoided screaming or oogling when we stripped naked to step into the tub. While we «bathed,» she pressed cooling wet towels to our foreheads and put straws to our lips so that we could drink cold water through our cups. The pampering was delightful.
If you’re wondering about the mulch stuff, it apparently is used by all guests for a while and then used on pathways on the property.
For $ 20, I upgraded to a deep tissue massage, which was very good. At the end, I was given a $ 20 discount coupon for my next massage.
As for other freebies, there’s tables with tea, almonds, dried fruit and other wholesome snacks.
And across the street, there’s a fantastic French bakery. It’s not open in the middle of the week so I didn’t get to try it.

Came here with a group of girls for a bachelorette, and we were so impressed! We started out by doing a cedar foot bath, which was incredibly interesting and unique. There are troughs of cedar shavings, which they’ve added enzymes to, causing the cedar to ferment. This makes the shavings warm, and it was quite nice to dip our feet into. Highly recommend!
Then we went to the hammock garden, which we rented for lunch. They provided us some coleslaw, chicken, and zucchini bread. They also let us bring our own salami, cheese, mimosas, etc. The service was incredibly attentive, and they were so accommodating.
If only there were closer, I wold take my sister and friends here!
TLDR: Definitely try the cedar foot bath!
