In addition to this "Lucania" had 16 transverse watertight compartments, with watertight doors that could be manually closed on command from the telegraph on the bridge. She could remain afloat with any two compartments flooded. In their day, both ships offered the most luxurious first-class passenger accommodations available. According to maritime historian Basil Greenhill, in his book "Merchant Steamships", the interiors of "Campania and Lucania" represented Victorian opulence at its peak – an expression of a highly confident and prosperous age that would never be quite repeated on any other ship. Greenhill remarked that later vessels' interiors degenerated into "grandiose vulgarity, the classical syntax debased to mere jargon". All the first-class public rooms, and the en-suite staterooms of the upper deck, were generally heavily panelled, in oak, satinwood or mahogany; and thickly carpeted. Velvet curtains hung aside the windows and portholes, while the furniture was richly upholstered in matching design. The predominant style was Art Nouveau, although other styles were also in use, such as "French Renaissance" which was applied to the forward first-class entrance hall, whilst the 1st class smoking room was in "Elizabethan style", comprising heavy oak panels surrounding the first open fireplace ever to be used aboard a passenger liner. Perhaps the finest room in the vessels was the first class dining saloon, over 10 feet (3.05 m) high and measuring 98 feet (30 m) long by 63 feet (19.2 m) wide. Over the central part of this room was a well that rose through three decks to a skylight. It was done in a style described as "modified Italian style", with a coffered ceiling in white and gold, supported by ionic pillars. The panelled walls were done in Spanish mahogany, inlaid with ivory and richly carved with pilasters and decorations. On 15 June 1901 "Lucania" became the first Cunard liner to be fitted with a Marconi wireless system. Cunard made a long trial of the installation, making their second installation to the RMS "Campania" on 21 September. Shortly after these installations, the two ships made history by exchanging the first wireless transmitted ice bulletin. In October 1903, Guglielmo Marconi chose "Lucania" to carry out further experiments in wireless telegraphy, and was able to stay in contact with radio stations in Nova Scotia and Poldhu.
