Arizona-based spa operator Canyon Ranch will be running the spas on Celebrity Cruises starting this April.

The spa company will work in partnership with Celebrity to bring the Canyon Ranch SpaClub at sea concept to Celebrity’s fleet of vessels.

The spas on-board were previously run by spa company Steiner, which operates more than 125 cruise ship spas, most of which are co-branded with each cruise line.

In addition to Celebrity’s spa treatment areas, Canyon Ranch will also operate all beauty salons and fitness areas on its ships.

Canyon Ranch and Steiner are the two major spa players on the high seas, with Steiner on more than 25 cruise lines and Canyon Ranch’s SpaClub at Sea on Cunard's Queen Mary 2 and the ships of Oceania, Regent and now Celebrity.

Canyon Ranch plans on introducing exclusive treatments and services tailored to the Celebrity clientele, including a range of new facial and body treatments, as well as yoga and meditation classes.
