Used to love this place when it was on Fillmore Street. Went in for a recent signature massage in Marin, and sadly was quite disappointed. The massage therapist rushed the appointment, and when I asked if she could apply more pressure, her response was: Im just getting started. Unfortunately the pressure remained light for the duration of the 90-minute massage. The visit also felt mechanical (which was especially unexpected given how long weve been in social isolation with the pandemic) rather than warm and welcoming. Sort of a next, check, next, check vibe. Sauna was missing tools to add steam/increase heat. Finally, upon checkout and payment, I was asked how the service was. I replied, okay. The clerk didnt ask for more information, what could be improved, or seem phased at all by my response. She simply asked how much did I want to leave in gratuity. In sum, the experience didnt leave me desiring a trip back (commuting from SF) or merit the cost for the experience. Much better options in SF in the $200-$300 range IMO. I get it (firsthand) that its its own adventure returning to providing services post-pandemic. I simply expected a more consumer-friendly professional experience given the human-centric nature of the business and the reputation of the brand.

One of my favorite spas to get a massage. I’ve been here three times and I’ll definitely be going back. They have a steam room and sauna and a beautiful lounge area where you can relax before or after your treatment & sip tea / eat snacks they provide. Great local spot to support!

This is my go-to spa in the Bay Area. The lounging area is smaller than most spas I’ve been to, but it’s right in Larkspur landing which has great shopping and food to wander through pre or post service. The Facialist and Masseurs are always amazing.

Perfect for a spa day. The space is surprisingly large; they have a nice indoor lounge area with fireplace and a huge outdoor deck that faces south.

This spa is BEAUTIFUL! The facial is beyond any other I have had and I totally use it as an excuse to stay and hang out all day in the sauna and lounge area.

Just what I needed on my business trip.

Serene and tranquil interior, minimalist design helps set the tone for a relaxing treatment. The waiting room -- with a very high ceiling and fireplace -- overlooks the bay from Larkspur Landing. The oxygen facial with Alicia included a massage and she took great care of me, talking me through the steps and describing the purpose of each. Highly recommend her for your appointment.

Beautiful, relaxing atmosphere. I enjoyed a luxurious, amazing facial, one of my best yet (and Ive had more than a few). Facilities are spacious, well appointed, bright, and calming. Staff professional and friendly. Enjoyed the experience from beginning to end. Marin doesnt have any spa quite like this.

The only destination/retreat spa in the bay! While nearly all other spas are located in busy urban areas or fall short in other ways, the Marin location is the local get away. Staff is warm and open hearted. Facials are superior and the product lines are some of the best. No other spa is as well curated, luxurious and expertly staffed.

Have been a few times now and love it. Calm & pretty facilities with a beautiful outdoor deck looking out to Mt Tam and the water. So relaxing!Staff is helpful, courteous, and low key. They even have a boutique in the front entry area that is filled with wonderful body products and a small selection of clothes. My massages have always been with Kelly who is amazing and seems to know just what to do to make you feel like a new person when she is done. Thank you & Well done all the way around IO Marin!

I bought a gift card for a dear friend so she could treat herself to a massage here and what a treat it was! The customer service was amazing and such a beautiful space. My friend loved every minute of the massage and said it was the perfect experience from beginning to end - shes even thinking about joining the membership program now! I cant wait for my next visit here.

I had a wonderful 90-minute deep tissue massage at IO. The space is so beautiful and calming. Got to lounge on the deck while waiting for my appointment and shopped some great products that I had never seen before. My massage therapist and staff were all very hospitable, professional and knowledgeable. This is a great place for a girls day out or for bonding with your daughter and/or mom. So excited that IO has come to Marin!

The service they provide is unbeatable. The manager Nicole checked me in and was extremely sweet and showed me around the spa. The lounge area is AMAZING! the spa is so peaceful and relaxing. I would go just to read a book if I could. I had a facial done by Summer. The service and quality is A+ all the way here.

Wow...what an incredible spa. There are no words. The space is beautiful and relaxing and I had the most incredible treatment (a facial!). I thought the San Francisco location was unbeatable but this is just amazing. A perfect place to relax. I cant wait to come back.

Finally, a true city spa, in the heart of Marin. Just like its San Francisco location, IO is a flawless space with high-end, modern, organic, hard to find products and incomparable treatments. I had the pleasure of receiving both a signature facial and massage and was delighted by both treatments. The staff is professional and experienced, knowing both product and procedure. I could have spent all day within its walls and gazing over the bay on its deck. I will return again and again. Great move Country Mart!

This is by far my FAVORITE spa in the Bay Area (and Ive been to them all). Its truly an oasis. The massages are incredible, the venue is beautiful (bonus points for the high ceilings and outdoor deck for lounging), and the magazine selection is ace. Im always thrilled to see they have my favorites: Porter, The Gentlewoman, Vogue, C Magazine, etc. If youre coming from the city and have time to take the ferry over (vs. drive), its the perfect intoxicating escape. If you dont have time to make the voyage over, International Orange on Fillmore is best in S.F.!

My mother and I went to IO in Marin for facials. We LOVED it. So relaxing! I have been to IO in SF as well. They are both great. I love how they have internet specials too. So if you have a day off in the middle of the week, you can get great deals!

We are so lucky to have International Orange in Marin. I had heard great things from friends that visited the San Francisco location and was so excited to have one open closer. I had an hour long facial and it was amazing. The location is beautiful with a relaxing deck and gorgeous bathroom/locker rooms. I highly recommend this spa!

I/O Marin is a beautiful new set up. Its gorgeous and Im so happy a second location has opened. The staff is so kind and its fun to have a different place to go knowing you will be well taken care of.

I had the most aaahhhsome experience at this beautiful, new spa. From the moment I walked into the reception area, I knew I was in for a treat! The space itself is lovely and feels super tranquil and relaxing - the white walls and beautiful floors throughout make it feel modern and clean. And they truly didnt miss a trick in taking every opportunity to turn a spa treatment into a whole spa experience: the changing area/showers are very spacious and well appointed, and the waiting/lounge area with the beautiful water views and deck (and delicious, healthy snacks) really made my before-and-after treatment time almost as lovely and therapeutic as the massage itself! And my massage was fantastic and truly just what I needed after a hectic workday - Cannot wait to return to I.O Marin, my new, go-to spa!

My biggest complaint about Marin was not finding a day spa, that felt like a day spa. IO nailed it!! From the moment you walk in, the external noise melts and your relaxing escape begins.From the pristine changing room & showers to the calming wait room, all corners of this oasis pamper your body and spirit from head to toe.Ive enjoyed several facials, favorite being the In Fiore, and several massages.. all exactly as wished for. The therapists consciously suggest products for you without shoving them down your throat. Every purchase Ive made from the carefully curated retail area has resulted in an empty bottle and wish for more!Well done IO. I seriously cant quit you.

Beautiful space with equally fantastic services. I went to Sarah for prenatal massages and was so grateful to have found such a talented massage therapist. IO also has a great selection of beauty products which make for perfect gifts!

I LOVE international orange. Ive been going to their spa for nearly 4 years now for facials. The biggest benefits of the experience are clean and calming facilities, really friendly staff and incredible products. I always see Eleanor for facials - she is really knowledgable about the right products and always customizes my facial to accommodate what is happening with my skin at the moment. One room for improvement - they really need to implement online scheduling as calling to make an appointment is a huge pain in the butt and waste of time.

Relaxing and beautifully designed space! The services are top-notch, as is the customer service generally. The team puts A LOT of thought into the products they use and carry, which I appreciate. Definitely my go-to place for any treatment.

Just dropped off the wife here this morning. Calling the location was easy and the person taking the reservation was helpful and friendly. At checkin had the same experience.I can’t speak about the massage services, though since I’m ticklish but hopefully the wife says it’s amazing.Note there’s no day pass.

Ive made the trek into San Francisco for years to get the best spa experience imaginable at International Orange. Imagine how thrilled I was to learn they opened in Marin! If you want the most exceptional facial or massage... this new location delivers that AND the most beautiful lounge, deck, and view in the Bay Area. THANK YOU IO!!!

I ended up at IO Marin as my normal go to day spa was closed for renovations...I have never looked back! The staff is so caring and the massage therapists are the best in the Bay Area. I love the space, the views and luxurious waiting room too. Definitely feels worlds away!

The view is absolutely amazing and such a great location in regards to convenience...easy to do some yoga nearby, get a massage and then enjoy a nice lunch! Location, location, location!All staff were extremely helpful and sincere. Will be back for sure!

I.O. Marin offers all we came to expect from San Francisco and then some. The location, deck and views only enhance the serene interior. Service and treatments are impeccable.

There are massages and there are international orange massages. It was so far and away the best massage Ive ever had that it deserves its own category. Will be going back ASAP.

International Orange is one of my favorite spas. The massages and facials I have received there have been top notch. Id highly recommend their services to anyone.

The best facials and atmosphere in Marin. Friendly staff. Can usually accommodate same day appts.

Nothing short of amazing. long overdue move to marin county. same superb quality of products and service as SF location, but now bigger and more spacious. a retreat beyond compare.

Best facial of my life! The enzyme facial left my skin glowing for weeks. Atmosphere is relaxing and clean, calming the nervous system and body for a true spa revitalization.

Wonderful experience, so peaceful and beautiful inside. Loved everything about my IO experience. Will definitely be back.

Just got an amazing facial from Summer! Highly recommend her! Wow!

This spa is amazing - best massage Ive ever had! The view from the relaxation room is beautiful, very cozy.

Amazing experience and not to mention amazing effects! Received an amazing facial and will be coming back . As someone who is serious about skin care, this is the only place I can fully recommend!

Love the peaceful environment and opportunity to dive into deep relaxation so close to home. IO is such a sweet treat.

This is a beautiful oasis in gorgeous Mill Valley providing a perfect spa experience that any and all can enjoy.

Beautiful space with great services! Will definitely continue to go back.

IO Marin is the most relaxing spa Ive ever visited. Theres truly something in the air in this spa that makes you feel instantly at ease from the moment you walk in. On days when I can get out of the city and see my all-time favorite esthetician Yolanda at IO Marin, it truly feels like Im a million miles away from the the noise and grit of SF. Theyve done an incredible job with the amenities in this spa so make sure you have extra time to enjoy the relaxing deck looking over the bay , the plush sofas with plenty of magazines, chocolate, cucumber water and tea to enjoy, the incredibly generous showers with IOs signature products that smell like West Marin in a bottle and of course their beautiful sauna. All of the products IO sells are incredible so even if you arent getting a treatment, its a great place to stop in and treat yourself to some new clean, organic makeup or skincare. I personally love how they are always rotating their skincare lines to offer the newest, freshest and latest in holistic, effective skincare. If I could go to IO every day, I would. Youll be completely spoiled for life!

Lovely calming space. Refreshing facial. Excellent service.

A beautiful space with skilled massage and facial therapists. My choice of a gift for anyone on my list.

Lovely from start to finish. Super nice staff with excellent skills.

Great Spa with amazing massages .. ask for Emiliana, shes amazing!!

I love international orange!

An outstanding spa and experience. Love IO Marin.

Beautiful space and wonderful facial.

Beautiful, relaxing space with great service!

Absolutely the best spa in Marin, hands down.

5 stars

Love it!
