Disadvantages of CORIAN®

Made by DuPont, CORIAN® is a nonporous counter top material that is available in more than 100 colors. It is easy to clean and resistant to mold, mildew and bacterial growth. CORIAN® comes in various thicknesses and appears seamless.

You also can get a matching CORIAN® sink and back splash installed for a more uniform look. However, for all its advantages, CORIAN® does have a few disadvantages.


Compared to other counter top surfaces, CORIAN® is expensive. At the time of publication, CORIAN® cost $35 to $80 per square foot installed, according to ConsumerReports.org. This is comparable to natural stone, such as granite and marble, which costs $40 to $100 per square foot installed; quartz, which runs $45 to $90; concrete, which is $80 to $120; and butcher block, which is $40 to $65. However, CORIAN® costs much more than ceramic tile and laminate, both which cost $10 to $30 per square foot installed. And, unlike ceramic tile, CORIAN® must be installed by a professional and is not a do-it-yourself project.

Heat Factor

Although Dupont says CORIAN® is heat-resistant up to 212 degrees Fahrenheit, the company recommends not putting hot pots directly on CORIAN® because it says high temperatures can damage the surface. Instead it recommends placing trivets with rubber feet or hot pads underneath anything hot.

Scratches Easily

Knives and other kitchen utensils can damage CORIAN®, according to The Home Depot; and, if you get a high-gloss surface, expect to see more scratches. The owner of Countertop Specialty maintains that even though you can sand out scratches, they will still leave a noticeable depression on the CORIAN®, and deeper dents are likely permanent.

Unnatural Look

CORIAN® is made of an acrylic polymer and clearly looks like plastic. Although this unnatural appearance won’t matter to everyone, those wishing for a natural look on their counter tops should stick to marble or granite.
