When buying a new sink for your kitchen or bathroom, you have a variety of materials to choose from. Porcelain and cast acrylic sinks look very similar, but have different benefits. For this reason, it can be difficult to choose between the two. Instead, pick a sink that matches your kitchen decor and has a level of durability that works with your lifestyle.


Both porcelain and cast acrylic sinks come in double and single sink styles. You can also choose between drop-in sinks (where the edge of the sink sits on top of the countertop), under-mount sinks (where the sink is mounted underneath the countertop), and self-rimming sinks (which can simply be dropped in place and secured with silicone). For the kitchen, both porcelain and acrylic sinks are available in the old-fashioned apron-front style, where the front of the sink extends over the front of the counter. For the bathroom, porcelain sinks are also available in the free-standing pedestal style and the vessel-mount style, where the sink sits on top of the countertop like a bowl.


Porcelain sinks are made when ground glass is melted and applied to a cast iron or metal base. This makes for a fairly durable material that comes in a variety of colors and shapes. Porcelain sinks have been around for hundreds of years and are often found in older homes. Cast acrylic sinks are made of acrylic material molded into a sink using a cast. This makes for a more lightweight material compared to other sinks. Acrylic also comes in a wide range of colors and can be purchased with a shiny or matte finish.


The price of porcelain and acrylic sinks can vary. In general, acrylic sinks are more affordable. More modern and expensive styles, like vessel sinks, are usually made of porcelain.


Porcelain can easily chip or scratch if you drop something heavy into the bowl. However, with good care, a porcelain sink can last for decades. Most high-quality porcelain sinks will last 25 to 30 years. Porcelain sinks absorb heat very well, and you may even have to refill the sink with hot water when doing lots of dishes as the sink will absorb much of the heat from the water. Acrylic is slightly harder to chip, but can still scratch fairly easily. Acrylic is not as heat resistant as other materials and leaving a hot pan on the surface of acrylic sinks can cause yellowing or warping.

Ease of Cleaning

Generally, you can easily remove stains from a porcelain sink. However, stains left for a long periods of time can become difficult to remove. Acrylic resists stains, and some models even come with germ-fighting properties. Both types of materials can be cleaned with basic household cleaners.
