Travel to the district Sukhumvit for this critically acclaimed gem. The spa sports a sleek, predominantly monochrome design and outstanding facilities, yet the hospitality is what makes this place shine. Quite a few spas in Bangkok opt for quick profitable treatments, whereas the staff at Treasure Spa prefer guest to take their time: Pick a package lasting a couple of hours or even a full day, drink some complimentary tea and let yourself be pampered. The Timeless Pearl package (which features treatments based on white roses including a milk bath) and the Rose & Champagne package (which can also be booked for couples) are highly recommended.
