Celebrity Cruises completely overhauled Celebrity Infinity just weeks before its European season started last month.
The Retreat Lounge has been given a refreshed look, the Luminae restaurant has been expanded and new Sunset Suites have been added at the back of the ship.
The work took place before the 2,170-passenger vessel began its European deployment.
Keith Lane, Celebrity’s senior vice president of hotel operations, said: “The enhancements to Celebrity Infinity, particularly the transformation of The Retreat Lounge, epitomises our commitment to providing an unmatched experience for our guests, ensuring that every journey with Celebrity Cruises is memorable.
"We strive to exceed guest expectations – from elevated service onboard and thoughtful amenities through to interior spaces designed to make guests feel at home in their surroundings.”
The ship is currently operating a mix of itineraries from its homeport Piraeus (Athens) before it switches to Barcelona in November.
