Bathroom Sink Materials: Your Choices
Whether you’re remodeling the whole bathroom or just replacing a chipped sink, there are a number of different kinds of sink materials to choose from. Prices vary, and they each have different strengths.
Ceramic Sinks
You can get custom glazed ceramic sinks from local potteries and from some larger manufacturers. Overall, ceramic is reasonably durable, but sinks made from the material have a tendency to chip or crack.
Vitreous China
One of the more common bathroom sink materials, vitreous china stands up well to even abrasive cleansers. Despite that, they can also crack and chip over the years.
Enameled Cast Iron
Cast-iron sinks are as tough as they sound. They’re fairly impervious to cracks, though it’s possible to chip to finish with enough abuse.
Enameled Steel
Enameled steel sinks are not quite as indestructible as enameled cast iron; they are more likely to chip and they are also noisier than cast-iron. You don’t see them so much today.
Stainless Steel
Stainless steel is more common in the kitchen than the bathroom, but these sinks can be appealing in the bathroom because they are easy to clean.
Cultured Stone
Cultured stone sinks are made from a mixture of crushed stone and polyester resins. The more money you spend, the more durable sink you get since more expensive ones have a higher percentage of strong minerals like quartz. Cheaper sinks often have a gel coat finish that cracks and blisters over time.
Solid Surface Sink Materials
Corian and related solid surface materials can be good choices because they are sturdy. If they do get scratched, that can be sanded out.

On our blog, The Daily Tubber, we have an article (http://vintagetub.blogspot.com/2005/06/fireclay-vitreous-and-porcelain-china.html) that further describes the differences between the three primary types of China that are used in the construction of sinks: Fireclay, Vitreous, and Porcelain China. Hope this helps.
