Arguably one of the most popular spas in Bangkok, this establishment prides itself on its Asian medicine inspired treatments and botanical ingredient based products. Outstanding specialty treatments include the Rattanakosin Passage (a foot spa and massage treatment for overworked professionals), the Ayudhaya Passage (a steam, body scrub and massage treatment based on traditional aromatic herbs) and the Sukhothai Passage (a complete spa experience with a tea bath, massages and a white mulberry facial). The spa also offers a wide range of massages and traditional facials for those with a briefer time frame.
