There are numerous options when it comes to the materials you choose for your sink, including acrylic, ceramic, stainless steel and glass. For sinks that are heavy-duty and heavy-use, stainless steel is best. It doesn't matter what gauge, steel provides the best protection against nicks, staining and damage from heat and washing. Ceramic is sturdy and is available in a variety of colors; they work well with bathroom sinks that are used extensively. Avoid glass sinks in the bathroom, particularly if they are not designed for kids. Although they can make beautiful decorative pieces, glass-vessel sinks are expensive and breakable.
