Guests on the four older ships of Oceania Cruises will see a modernization of their interior design starting this December, when the Insignia goes into drydock, and ending with the Nautica in June 2020.
Norwegian Cruise Line Holdings-owned Oceania said it will invest $100 million in the ships, which were built from 1998 to 2001 for Renaissance Cruises.
The improvements will start with the 342 staterooms and suites, which will be "stripped down to their studs," on each ship, an Oceania statement said.
"Every ounce of the reinspired accommodations will be modernized, featuring custom-crafted furnishings, exotic stone and polished wood finishes and designer accessories," Oceania said.
USB ports will be added in each of the staterooms as well as a state-of-the-art television system with movies on demand in multiple languages.
Studio Dado, a Miami-based design studio, will oversee the interior overhaul.
Three of the four 684-passenger ships were the founding core of Oceania, which were acquired starting in 2003 following the bankruptcy of Renaissance. Their last major interior overhaul was 10 years ago.
The Sirena was purchased from Princess Cruises in 2016 and received $40 million of improvements before it was relaunched as an Oceania vessel. It isn't clear how the $100 million in the Oceania-Next renovation program will be spread among the four ships.
Oceania said its two newer ships, the Riviera and the Marina, would serve as "muses" for the redesign.
Public areas, such as the Martinis lounge, will be redone featuring hues of deep Grecian blue, sienna and chocolate browns and stately pewter. Silver-white marble and tobacco quartz will accent the bar.
In general, the color scheme will be lighter and more marine, while the upholstery will be sleeker and more modern.
Another focus area will be the bathrooms. Oceania said every fixture and surface in the bathrooms will be new, with "designer features, perfect lighting, lavish vanities and chic glass shower enclosures."
Bathrooms in the Penthouse, Vista and Owner's suites will have more space and be outfitted with Carrara marble, polished granite and sleek onyx.
Following the Insignia, the Oceania-Next program will be applied to the Sirena in May 2019 and the Regatta in September 2019, before concluding with the Nautica in June 2020.
