Q: We are installing a new vanity and want to have a vanity top instead of a countertop and a sink. The choice is a little complicated due to all the new styles out there. Can you please give us some vanity top tips?

A: Vanity tops are a good choice in general, since the sink and countertop are one self-supporting unit. Design-wise, this allows for a sleek look since the sink is a seamless depression in the top itself. The design not only can create a unique-looking sink, it also allows for easy cleanups.

The big choice will be picking out the material. Here are four popular materials that I like for vanity tops:

Glass: Thick cast glass tops can provide a contemporary look, especially if you install backlighting.

Vitreous china: Traditional beauty in an affordable package.

Solid surface: Strong manmade composite material available in many different sizes.

Enameled cast iron: Elegant yet strong, cast iron is also a green material, making it a top choice for a vanity top.
