High-gloss cobalt walls set a glamorous backdrop for an Art Deco bathroom with a curved glass-block shower and a black clawfoot tub on a stepped marble plinth. Carrara floors, framed in deep blue marble, showcase a bold Greek-key inlay. A brass-rimmed porthole, ribbed glass sconces, and chrome fittings gleam under cyan cove lighting, while skyscraper graphics and marble wainscot emphasize Deco geometry and cruise-liner elegance.
