When choosing a countertop material for your kitchen or bathroom, two popular options are Corian solid surface and granite. Both have their pros and cons in terms of appearance, durability, maintenance, and cost. This guide provides an in-depth comparison of Corian vs. granite countertops to help you select the right material for your needs.

Overview of Corian Solid Surfaces

Corian is a solid surface material made from acrylic polymer and alumina trihydrate. It was first introduced by DuPont in 1967 and continues to be manufactured today by Corian Group LLC. Some key facts about Corian:

  • Seamless installation – Corian can be fabricated into seamless countertops with integrated sinks for a sleek, modern look.
  • Customizable – Corian comes in a wide range of colors and patterns that can be customized for each project. It can also be thermoformed into unique shapes.
  • Repairable – Minor scratches and damage can be sanded down and repaired on site. Corian is even reformable if severely damaged.
  • Hygienic – Non-porous surface resists stains, mold, mildew, and bacteria growth.
  • Durable yet flexible – Corian is resistant to heat, scratches, and impacts, while still being flexible for molding and shaping.

Overview of Granite Countertops

Granite is a natural stone quarried worldwide in many colors and patterns. It has been valued as a prestigious countertop material for its beauty and durability. Key granite features:

  • Unique aesthetics – Granite slabs have one-of-a-kind natural veining and speckling that no two pieces are exactly alike.
  • Heat and scratch resistant – Granite is very hard and withstands heat up to 500°F. It resists cuts and abrasions.
  • Stain resistant but sealing required – Granite is impervious to liquids but sealing is needed periodically to prevent staining from oils.
  • Durable and long-lasting – Granite can last for decades with proper care and resealing. It does not need replacing like synthetic materials.
  • Adds value – Natural granite countertops increase a home’s resale value and are viewed as luxury features.

Comparisons of Corian vs. Granite


Both Corian and granite offer attractive options for countertops. Corian provides limitless custom colors and seamless appearance. Granite offers natural beauty and uniqueness with its inherent veining. Granite tends to be viewed as more prestigious.


Corian and granite are both highly durable. Corian is impact resistant and repairable, while granite better resists cuts, heat, and scratches. Both should last many years if properly maintained.


Basic maintenance is easy for both materials – just use mild soap and water for regular cleaning. Corian requires no sealing. Granite needs periodic sealing to prevent staining. Corian can be repaired in place, while granite will need replacement if extensively damaged.


Granite is exclusively a natural stone so it commands a higher price, costing $80-$150 per square foot installed. Corian ranges from $50-$100 per square foot. Granite’s resale value may offset the higher initial price over time.

Heat Tolerance

Corian can withstand temperatures up to 212°F before warping or discoloring. Granite has superior heat tolerance up to 500°F. Granite is better for frequent hot cookware placement.


Corian’s nonporous surface makes it very hygienic resisting mold, mildew and bacteria. Granite requires sealing for maximum sanitation and stain resistance. Both materials are safe and sanitary if properly cared for.


Corian allows for seamless countertop fabrication and built-in sinks. Granite requires seaming between slabs which must be expertly done to prevent bacteria and moisture getting in. Granite is very heavy, often needing reinforcement to support the weight.

Colors and Patterns

Corian offers a rainbow of solid colors and customizable patterns. Granite has natural, unique veining and crystallization that varies dramatically between slabs. Corian can mimic patterns like marble but granite’s beauty comes from nature.

Environmentally Sustainable

Corian is manmade using some recycled content. Granite is completely natural and abundant. Both contain no VOCs. Granite is ultimately more eco-friendly as a natural material, but Corian makes an effort towards sustainability.

Cost Comparison

Here is an overview of average installed costs for Corian vs. granite countertops:

| Countertop Material | Average Cost Per Square Foot Installed |
| Corian Solid Surface | $70-$100 |
| Granite | $80-$150 |

Granite is almost always more expensive than Corian, but exact costs vary by supplier and complexity of installation. Unique granite colors and patterns can also impact cost. Many homeowners view granite as a worthwhile investment into their home’s value.

FAQ About Corian and Granite Countertops
