Imagine stepping into a peaceful oasis amid the bustling streets of Bangkok. For just $15, you can indulge in a Japanese-inspired onsen experience at Let’s Relax Onsen and Spa, conveniently located on the 5th floor of the Grande Centre Point Hotel in Thong Lor. This boutique chain with over 38 branches aims to bring that calming Japanese bathing ritual to the heart of Bangkok, and it does so with a surprising level of authenticity and comfort.

What truly draws us in is the wide variety of mineral baths and the extended menu of massages—a perfect combo for both relaxation and rejuvenation.
