Thief Spa is a design-forward luxury wellness retreat located within The Thief hotel on Tuvholmen, a small islet in central Oslo with breathtaking views over the Oslofjord. The spa's interiors draw inspiration from Norwegian sea, forests, and natural light, while its ritual menu borrows from Turkish hammams, Moroccan rhassoul, and German Aufguss traditions to create an experience that is distinctly Nordic in spirit. A 12-metre heated pool with counterflow jets and a therapeutic light display, a Finnish sauna, hammam, steam room, Sensory Sky showers, and a gym form the core facilities. The extensive treatment menu features massages with premium essential oils, signature facials from BABOR and Natura Bisse including the exclusive 3D Collagen Shock anti-aging treatment, a Moroccan-clay body ritual, and the THIEF MUDDY hot-salt and warm-clay body wrap. Guests can conclude their spa journey with a refreshing dip in the Oslofjord, just steps away, making Thief Spa one of Oslo's most memorable wellness addresses.
