Celebrity Eclipse underwent a scheduled dry dock at Damen Shiprepair Brest in April 2025. Celebrity confirmed that the yard operation ran later than planned, delaying the ship's subsequent Amsterdam departure from April 27 to April 28.

Reported passenger-area work included the addition of ten inside staterooms in spaces formerly occupied by facilities such as the internet café, technology shop, card room and video arcade. Carpeting, furniture and selected public areas were refreshed, and improvements were reported for The Retreat facilities. Routine maintenance, survey and technical work were also undertaken.

Celebrity Eclipse completed her first major scheduled refurbishment, introducing several new dining, beverage and guest-experience concepts. Cellar Masters was transformed into Gastrobar, combining craft beers with an expanded food menu and tablet-based ordering, while the pool deck gained the Slush frozen-drink bar. The casino was updated with British-themed gaming features, and a private portrait studio was added. The project also introduced Celebrity's enhanced Suite Class experience, including the suites-only Luminae restaurant and associated premium services.
