Stepping from the heat into the modern, white-marble-walled treatment rooms of Kamala Royal Thai spa is extraordinary, as the scent from incense diffusers circulates within the cool rooms, helping you relax before the treatment has even begun. The spa building, which was once a house, has a distinctive open-plan retreat of solid wood pillars, marble floors and wall features. There are eight beds for oil massage, four beds for traditional Thai massage and an area that seats six for foot massage.
