Reviews of Yunomori Onsen & Spa (Sukhumvit 26) (Bangkok)
Klayboon
Hands best spa I've ever been to out of my grand total of 1. I was slightly apprehensive of the experience based on the reviews saying you just need to accept and embrace the culture- admittedly it was a shock but you get used to it very quickly. The baths were truly relaxing and they have cycles to follow on the wall- I recommend. The massage was true and proper. Don't really know how else to ...

The atmosphere is peaceful and calm. Onsen bath is not too hot and massage is nice. The best way to relax on your weekend. Both onsen day pass & 60 min Thai massage cost 1250 THB.

After 2 days of shopping, I just can’t anymore. This is really the perfect place to relax. Onsen and thai massage cost me 1250. My masseuse Nok was really strong and awesome so if you choose strong, just know it will be delivered. 🫡 There’s no sauna though, that would have been the icing on the cake. Glad I made the decision to come.

After a long day of walking around Bangkok, I visited the Onsens on Sukhumvit and was absolutely delighted. The baths were fantastic, and they provide everything you need, from hair ties to kimonos. It was an unforgettable experience, and so sad that such a place doesn’t exist in my city.
