"Lusitania"s first-class accommodation was in the centre section of the ship on the five uppermost decks, mostly concentrated between the first and fourth funnels. When fully booked, "Lusitania" could cater to 552 first-class passengers. In common with all major liners of the period, "Lusitania"s first-class interiors were decorated with a mélange of historical styles. The first-class dining saloon was the grandest of the ship's public rooms; arranged over two decks with an open circular well at its centre and crowned by an elaborate dome measuring , decorated with frescos in the style of François Boucher, it was elegantly realised throughout in the neoclassical Louis XVI style. The lower floor measuring could seat 323, with a further 147 on the upper floor. The walls were finished with white and gilt carved mahogany panels, with Corinthian decorated columns which were required to support the floor above. The one concession to seaborne life was that furniture was bolted to the floor, meaning passengers could not rearrange their seating for their personal convenience.
