The largest Four Seasons spa has opened at the Four Seasons Bahrain Bay on a private man-made island off the Kingdom’s capital city, Manama.

Designed by Skidmore, Owings & Merrill, the 273-key property has interiors by Pierre-Yves Rochon, EDG and Los Angeles-based Waldo Fernandez.

The 37,512sq ft (3,485sq m) spa, masterminded by Rochon and Blu Spas Inc, houses 17 treatment rooms plus his and hers spa lounges – all located within four interconnecting garden buildings. Sodashi and ila provide the skincare for the spa and Gharieni supplies all the equipment, including its Quartz beds.

There are also two gyms at the property, one unisex and one for women only.

The urban resort also hosts five different swimming experiences, including a children’s pool, a pool that sets the scene for a cocktail lounge during the evenings, a free-form infinity pool, indoor spa pool and a saltwater experience.

Complete with seven dining venues, the resort will be operated by 600 staff.
