The Marble Factory has been manufacturing engineered marble, granite, onyx and Solicoat vanity tops since 1984. Advantages of our material include complete customization, we custom make every vanity top to suit your specific needs. Whether you need a small top for your basement bar, or a one piece vanity top that's 12 feet long, or has custom angles or curves; we can accommodate. With our integral bowls (sinks) moulded right into the vanity top, there are no joints between the bowl and the top to collect dirt, mildew and mould.
