Already deemed one of the boldest hotels to open in 2013 with video art installations and a location amid Oslo’s urban waterfront, The Thief has unveiled its 800-square-meter spa. Inspired by Scandinavian wellness expertise, the Thief Spa features a pool, sauna, steam room, and Oslo’s first hammam bath. Danish architecture firm Schmidt Hammer Lassen, with added design touches by Anemone Wille-Våge, are behind the spa’s clean Nordic design. The 12-meter swimming pool glows with mood light from blue to red to green, while tiny ceiling lights mimic the Nordic night sky. Panels of slate and wood along with color block, Mondrian-esque doors bedeck the six treatment rooms. The spa offers traditional treatments from facials to massages, but with infusions of Turkish, Moroccan, and Japanese elements. The Laminaria Algae facial uses handpicked algae from the Irish coast while the German and Finnish Aufguss technique of pouring water and essential oils on hot rocks is available in the sauna.
