Marble Wall Mosaic: Sonata, of such a large scale, gets its name from the Italian “to sound.” As the term evolved through history, it took on a whole other meaning – a principle of composing large-scale works. This grand bathroom can hardly be called a bathroom at all. It’s large size puts others to shame, and its use of only the finest ingredients produces a room that is crisp and clean. Lavish touches, such as inlaid tile work on the walls and ceiling, a bathtub for royalty, and a fountain, complete the magnificent two-level bathroom space.
