Atlas Ocean Voyages will have a L'Occitane en Provence-branded spa at sea, the Luxury SeaSpa by L'Occitane.
The brand's first ship, the World Navigator, set to launch on an inaugural Holy Land and Black and Mediterranean Seas season in July, will offer a holistic and sensorial menu in the SeaSpa, Atlas said.
In addition, all accommodations will also have complimentary L'Occitane shampoo, hair conditioner, body wash and handwash.

Located on the main deck, Deck 4, the 947-square-foot SeaSpa will feature L'Occitane's Relaxing Pillow Mist signature scent, two treatment rooms, an infrared sauna and plush loungers in the serenity lounge, which will have oceans views through expansive windows.
The SeaSpa treatments, which will feature L'Occitane ingredients from Provence, will include a Sleep & Reset Massage, a 90- minute massage said to help with one's sleep quality, according to the European Sleep Center in Paris.
Atlas' parent company, Mystic Invest, currently partners with L'Occitane for its DouroAzul river cruise vessels in Portugal. Mystic chairman Mario Ferreira called the partnership's expansion to its ocean brand, "a positive, organic next step."
After its inaugural season in Europe, the World Navigator will sail the Caribbean and South America before heading to the Antarctic peninsula, starting Nov. 19.
