Once Upon A Thai Wellness Spa and Private Onsen | Ratchadamri in Bangkok

I chose the “Herbal Habitat” package for HKD$797 here on KLOOK. The staff there are very friendly, and the place is very clean. Please make sure that you search for “Ratchadamri Branch” at 231/4 Soi, Sarasin Rd, Lumphini, Pathum Wan, Bangkok 10330 Nearby BTS Chidlom exit 4 or BTS Ratchadamri exit 1. To make sure you arrive on time, I recommend taking BTS and spare extra 15 more minutes in case you have a hard time looking for the location. Just keep following the google map, and you will find the location easily.

What a blissful experience! I booked the Anodat Journey package for 1, and felt do pampered from the first minute to the last. Private onsen felt so luxurious, the room was spotless and interior was new and calming, there was a private shower inside the suite that you can use after the massage. Massage bed was slightly heated, and my masseuse even placed a menthol-y bowl of aromatic oil below my face to help with my congested sinuses. overall, a luxurious experience that was worth every cent!

My husband and I had the pleasure of experiencing the “Once in Thailand” treatment at Once Upon a Thai, and we were thoroughly impressed. From the moment we stepped through the doors, we were enveloped in a calming and welcoming atmosphere. The 30-minute Private Onsen (Oxygen White Ion) was incredibly soothing, and the 90-minute Signature Therapeutic Aroma Massage was the perfect way to release tension and fully unwind. Every detail of our visit, from the serene environment to the professionalism of the staff, made this experience unforgettable. We left feeling rejuvenated and truly cared for. Thank you for making our time so enjoyable from start to finish! We will definitely return sometime soon!

Everything was perfect! From booking an appointment to post spa treatment. The Sky After Rain + Private Oxygen White Ion Onsen Package is definitely worth it. You get to pick your oil and scrub. Even the gelato after the massage.

Lovely environment; great service and enjoyable massage; very easy to book via KLOOK; prompt response on booking confirmation; good value for money especially when there is promotion or discount code on KLOOK.

the place was very tastefully designed. ambience is great. rooms are private and very clean. services are also really high standard. staff spoke english well and i basically enjoyed my time there very very much.

Great experience, place is clean, massage is good, service is excellent. I LINE them to check for available slots before booking, response is quite prompt. Tip for first timer like me - change into the underwear provided (communication with masseur might be a bit lost). Place is slightly out of the way, a 10 mins walk from Ratchadamri BTS station.

the location is easy to find even i travel by MRT. 15mins walk from MRT to the spa. the onsen is okay and massage is good. love the dessert after spa as usual.

ABSOLUTELY LOVED THIS! best value for money, everything was so relaxing and serene. they also prepare the shower for you and handle everything. staff was so nice and I loved the coconut ice cream

We visited with 10 people and everyone was satisfied. The building, surrounding facilities, and even the streets were clean and modern. All the staff were friendly and the massage was luxurious. Rather than making it very cool, it feels like they put a lot of effort into it to suit the price range. The ice cream given at the end was also delicious. I recommend it~!
