A state-of-the-art spa will be available to passengers on board Marella Explorer from May 2018.
It follows the announcement of a new partnership between the recently re-branded Marella Cruises and luxury UK spa brand Champneys.
The spa will offer facials, body wraps, massages, manicures, acupuncture as well as a salon, wellness centre and a relaxation room.
Marella Explorer, set to be based in Palma, Majorca, is the cruise line’s biggest ship.
Helen Caron, distribution and cruise director at Tui UK & Ireland, parent company of Marella Cruises, said: “This new introduction on Marella Explorer will ensure [guests] can fully unwind in luxury.”
The announcement comes just days after Tui appointed Christopher Hackney as managing director of Marella Cruises.
Hackney takes up his position on December 1.
