The Oriental Spa belongs to the Mandarin Oriental, Bangkok, set in a restored century-old teakwood house on the Chao Phraya River and reached by the hotel's short ferry crossing. Billed as the city's first five-star spa, it draws on Thai, Chinese, and wider Asian healing traditions. Facilities include ten treatment rooms and five suites with steam and vitality pools, and the signature Soul of Siam massage is a longstanding draw. Reserve in advance.
