The bow-to-stern revamp will introduce Carnival’s food, drink and entertainment brands, and various new accommodation.
Work will get under way in Cadiz on March 1 next year, with the dry dock renovation scheduled to last two months.
Sunrise will re-enter service on April 29 with a series of five to seven-day voyages from Norfolk, Virginia.
It will then sail a summer schedule of four to 14-day departures from New York starting May 23 before relocating to Fort Lauderdale in the autumn.
Christine Duffy, Carnival Cruise Line president, said: “The introduction of Carnival Sunrise will provide our guests with an array of exciting dining, bar and entertainment choices.
“The new Carnival Sunrise is part of our multi-billion-dollar ship enhancement programme that is transforming our fleet on an unprecedented scale.”
The makeover will see its Captain’s suites redesigned and its staterooms updated to reflect the line’s various itineraries.
New food options include Italian-style family restaurant Cucina del Capitana, the Fahrenheit 555 steakhouse, Guy’s Pig and Anchor smokehouse and Bonsai Express sushi restaurant.
The ship will feature four bars - the RedFrog Pub, Piano Bar 88, Limelight Lounge offering comedy and multi-purpose Liquid Lounge and theatre.
Other improvements include the SportSquare, complete with basketball court, running track and miniature golf course, new water slides, an adults only retreat, extended Cloud 9 spa, new children’s activities and play areas, a games arcade and mall-style shopping area.
