The basic choice here is pedestal sink.a basin supported by a single column.versus a vanity sink.a full-size cabinet beneath the sink. But after that decision is made, the hunt for a bathroom sink is wide open: marble, granite, onyx, and glass are the most popular choices in materials, and you can get exotic sinks with colored lights that change the hue of the flowing water on demand. A sink is such a prominent bathroom piece that you can update your bathroom by replacing the sink alone or pick a style that sets the theme for a whole new look.
