The St. Regis Spa at The St. Regis Saadiyat Island Resort sits on the resort's stretch of Saadiyat beach, and the brand describes it as a homage to the Iridium Room at The St. Regis New York. The menu carries that heritage through, with rituals named after Caroline Astor and New York's gilded age alongside beach-inspired treatments.

Massages follow the St. Regis format of Performance, Stress Relief, Relaxation and Re-Energize, each in 60- or 90-minute versions, with oils personalised at a Scent Bar. Beyond those, the menu lists Ancient Traditional Thai, Where Oceans Meet (a Balinese massage blended with mindful breathing), Moonstone of Morocco with smooth selenite stones, and a four-hands massage performed by two therapists in sync.

Hammam lovers can choose the 60-minute Green Purification Hammam, a 75-minute Traditional Turkish Bath with black soap and foam massage, or the 90-minute Ancient Oud & Rose Hammam; a three-hour Royal Oud & Rose Hammam Ritual goes further. Facials include HydraFacial and cryo-inspired Glacial treatments, and a men's section covers targeted massages and HydraFacials. Couples can book An Exquisite Spa Date in a private couples spa suite, and a private Jacuzzi can be added for 30 minutes. The spa is open daily from 11:00 AM to 11:00 PM, and prices on the online menu are in AED.
