Let’s Relax Onsen and Spa · Reviews
Got there early when it was quiet, soaked in the baths, and then had a Thai massage that actually hit all the right spots—plus mango sticky rice after? Yes please.
Ezra H. (2026)Let's Relax Spa's signature store truly exceeded my expectations. The massage was superb, and the five-star onsen was a luxurious treat. The hydrating moisturizer added an extra level of pampering that made my visit even more enjoyable. I can't wait to return to Bangkok for another incredible experience at Let's Relax Spa.
Nipha (2025)I had the most amazing experience at Let's Relax Spa! The environment was clean and comfortable, and the massages were incredibly relaxing. The staff were friendly and the post-massage snack of mango sticky rice and jasmine tea was a nice touch. It was definitely worth every penny for such a wonderful experience.
