The Sandals Barbados will close on April 1 to begin a $65 million face-lift of the 280-room resort.
The resort is scheduled to reopen in December.
Guests holding reservations after April 1 can relocate to any other Sandals, Beaches or Grand Pineapple Beach resort, excluding Sandals Emerald Bay in Exuma, Bahamas, and Sandals LaSource Grenada.
The resort is the former Couples Barbados, which Sandals acquired last year
"When we acquired this property, we knew we were buying great potential; here was a lovely resort that could be transformed into something magical. The time has now come for the 'Sandalization' to start and drive forward into what is an exciting future for Sandals and Barbados as a destination," said Sandals Chairman Butch Stewart.
Renovations will include the introduction of seven new restaurants, including Sandals' first Indian restaurant, bringing the total to 10.
Other enhancements include a refurbishment of the resort's guestrooms; the addition of a Club Sandals lounge, departure lounge and an expanded Red Lane Spa; a wedding garden; and a swim-up pool bar and beachfront whirlpool.
The resort also will launch a new attractions program that is expected to get more guests out of the resort to experience Barbados.
Two new tennis courts, eight new elevators, WiFi and the introduction of Sandals' butler program will complete the project.
Stewart said that the new Sandals Barbados will mirror what was created at its new Grenada resort in terms of creativity and design innovation.
