When celebrated Taiwanese designer Tony Chi created this club-style hotel spa, he made it one of Bangkok's most beautiful wellness retreats. The indoor-outdoor setting feels more like a jungle resort than a city spa, featuring six residential spa cottages, nine treatment bungalows, a hair salon and a nail bar—not to mention a modern fitness center, squash and tennis courts plus a 25-meter pool. Treatments include full day 'Retreats', half-day 'Escapes', and a huge variety of facial, full-body and massage options.
