A Pinterest-perfect haven of sophistication, Panpuri Wellness is where you can escape the bustle of central Bangkok with luxurious treatments paired with dips in a Japanese hot spring. The 2,000 square meter wellness sanctuary has a number of mineral-rich onsen pools that help stimulate blood circulation, and prepare your body and mind for ensuing treatments, be it a Japanese Akasuri exfoliating ritual, a muscle-pummeling deep tissue massage or a traditional Thai massage. And if you want to bring your Panpuri experience back home, you're welcome to shop for fragrant oils and body scrubs at the gift shop.
