The buzz: The Art Deco-themed urban resort The Siam recently added the final touches to its ground-floor wellness retreat, Opium Spa.

The décor: Located a step lower than the ground floor, Opium Spa’s dimmed lights, dark hues and sophisticated Asian-meets-Art-Deco accents have the feel of a secret sanctuary. The vast space is filled with only five suites, each of which is incredibly spacious at 80 sq meters—large enough to fit a separate changing area and an even larger treatment room. (We really love its soft, adjustable bed.) Post-treatment, guests are free to access the Hammam-inspired bath house where you can lounge in one of the daybeds or relax in the Jacuzzi pool and steam room.   

The treatments: All treatments here are exclusively designed and make use of Sodashi products, an Australian organic brand only available at high-end spas. Feel free to ask which treatments fit your lifestyle, from the de-stress massage to rejuvenating facial treatments. Then you set to choose your preferred scent of oil (if you choose an oil-based massage) before being escorted to the suite. For those of us with office syndrome, the therapist recommends you try the 60-minute muay Thai massage (B3,500; B4,900 for 90 mins) that combines Thai and Swedish techniques to release stress and deep muscle tension, as well as focus on spots in need of special care. Sodashi oil is light it’s quickly absorbed into the skin, too. Prices are B1,500-10,800.

Why you come back: The overall spa experience here is akin to being treated like a superstar at some exclusive retreat. Only problem—it’s not cheap at all. Top Koaysomboon
