Corian countertops are often regarded as a third cousin whose time has passed compared to more "glamorous" kitchen countertop materials. But Corian has continued to evolve and deserves a second look because it can offer truly unique qualities and a new world of possibilities for achieving a much more creative kitchen design.
Many consumers are confused about Corian and solid-surface countertops and materials. What are they made of? How do they compare to granite and quartz?
This detailed review will cover what Corian is made of, its pros & cons, cost, colors, design options, cleaning, care, and repair. Additionally, you will also find buying tips and warranty info for DuPont solid-surface countertops for kitchens and bathrooms.
Corian is a brand-name for a type of countertop called "solid-surface" invented by DuPont back in 1967. Solid-surface is a man-made or engineered material (quartz is too) vs. granite, which is a natural stone pulled from the earth.
Solid-surface and Corian countertops are made by blending acrylic polymers with other minerals and stone-derived materials. This mix is poured into molds to make half-inch-thick sheets. The composition is consistent all the way through; in other words, it is solid and is exactly the same inside and out.
This blend allows for some cool features and benefits not available with other types of countertops. Epoxy countertops are a similar countertop material.
Corian by DuPont, which also makes Zodiac quartz counters is the big cat on the block and is increasingly popular.
However, since DuPont's patent ran out, other solid-surface brands have jumped in with their own version of these countertops. These other versions include Staron, Swanstone, Avonite, Wilsonart / Gibraltar, Formica, LG, Hanex, and Meganite.
Differences in the "recipe" do exist between manufacturers, but the end result is essentially the same type of countertop material. Corian worktops are a durable kitchen countertop with specific advantages, but as you will find with all countertops, they come with some drawbacks too.
See how Corian countertops compare to a granite or quartz countertop.
Every countertop material has its good and bad points, but Corian countertops hold up pretty well overall.
Corian colors in the past were limited to some pretty boring and subdued earth tones with a monotonous, speckled pattern. While appealing to some, these colors really couldn't compare to the depth and natural beauty of stone.
Luckily, those days are gone. Finding a new flair, patterns designs have expanded beyond the uniform speckled look of old with over 100+ Corian countertop colors now available encompassing a broad range of textures and looks that fit right in with modern bath and kitchen style.
You can still pick from a wide range of neutral beige and brown colors along with popular grays. Pure black and white Corian countertop colors like Glacier White and Deep Nocturne serve the modern-minimalist aesthetic and work great for a more classic or transitional kitchen design as well.
Some colors in the Corian lineup utilize up to 20% recycled materials for a greener alternative.
And Corian colors get playful with solids in yellow and blue too, which few other materials can offer. Golds, purples, pinks, corals, and coppers fall in-between.
The evolution and addition of new patterns, though, is what's so enticing offering options for any bath or kitchen design theme.
Grain shapes and sizes vary from sand to pebble and even to recycled glass. Striations, veins, mottled color shading, and movement are now seen throughout the collection for a far more natural look that is very appealing. Many pleasing patterns mimic marble, travertine, and granite quite well.
Custom colors are possible too if you can believe it! Send Corian a sample color from a fabric or paint sample, and they will match it.
Corian counters have some truly unique features that many are not aware of. Some are subtle benefits while others are more dramatic and offer more desirable elements of design and function.
Edge styles to suit most bath and kitchen design ideas are possible with DuPont Corian countertops. From a simple eased or bullnose edge to a fancy Spanish style; there are around 20 different styles offered.
A thick edge profile to simulate a huge block countertop, or to create the more elaborate designs is easily accomplished with a laminated edge. In most cases, the seams of a laminated edge will be invisible as well. You can typically see these seams when it comes to granite surfaces.
Backsplashes can be installed traditionally just like with granite, marble or quartz countertops. You can use stone, glass or metal or ceramic tiles configured in any design that suits your fancy.
You may even choose to install a full backsplash using the same Corian color as you used on the countertops. Note that the wall seam can be eliminated by molding a Corian backsplash into the countertop.
Corian sinks come in myriad single and double bowl configurations, colors, and sizes. They have your lifestyle demands covered for kitchen and bathroom countertops.
Sinks can be installed in all the usual ways such as top-mounted, undermounted, flush, beveled, or molded right into the countertop for a seamless design.
Drainboards for sinks are commonly integrated right into the countertop to help keep the area tidy.
One thing to consider with an integrated sink is that a sink gets a lot of use and abuse and if it gets stained or worn you likely will have to replace the entire countertop versus just the sink.
Integrated sinks need a bit more care and attention as well. For instance, Corian states that boiling water should not be poured in the sink as it could warp it.
But, there's no denying that an integrated sink is very stylish.
Seams are the bane of all other countertop materials. The one undisputed advantage DuPont Corian and other solid-surfaces have over all other materials are the nearly invisible seams.
Corian surfaces must still be installed in pieces or sections like other materials, so your counter will have seams, but the materials and system used usually results in a monolithic, "seamless" look with most colors—especially solids.
Seams may still be somewhat visible on the more elaborate patterns with a less repetitive or consistent design. Considering there's little to like about visible seams, Corian surfaces are the clear winner in this category
Corian can be molded into essentially any shape or curve via thermoforming allowing for almost limitless design possibilities. That's a great characteristic if you want an unusual shape or your space is an unconventional shape.
This pliability is what also allows for integrated sinks, seamless backsplashes, and inlays, which no other material offers.
Illumination (lights installed to glow through the surface) is also possible with Corian kitchen countertops.
And get this... you can now... charge your phone with Corian's new charging surface. An adapter on your phone or tablet allows it to charge simply by setting it on the countertop surface. No more wrestling with cords and finding available outlets.
Corian isn't just for the kitchen. It's possibly the most versatile and adaptable material also used for bathroom countertops, tub and shower surrounds, bar tops, wall cladding, furniture, boats and RV's.
The costs associated with Corian installation are far more affordable than granite or quartz countertops. The material itself tends to be less expensive, it's not prone to cracking, and is generally easier to fabricate with less waste; all of which translates into lower prices for the average, basic install.
However, when comparing countertop materials, don't be surprised if the Corian price for your particular kitchen countertop design is similar to the quotes you get for a quartz or granite countertop installation.
The final Corian countertop costs can vary tremendously depending on the color chosen, the complexity of the kitchen and countertop configuration, corners, bar tops, intricacy of design details like edges, sink mount, drain boards and inlays, special shapes or molding, or illumination of the countertop surface (which is possible with Corian).
Labor costs will also vary significantly at times between different contractors. Costs can also vary from city to city, region to region, and even seasonally. So, the above gives you some idea of what you can expect to come close to spending.
Generally, you will pay 10% to 20% less than you would for granite or quartz countertops but getting detailed bids from several contractors is necessary to accurately determine the cost of your installation.
When comparing solid-surface brands, most will fall into the same price range, although, Corian is usually the most expensive of the solid-surface brands. But for a good reason. Corian has the best product with decades of development behind it.
And for additional material comparison, laminate countertops are still far cheaper than Corian or any solid-surface countertop.
Cleaning Corian countertops is easy. Soapy water is fine; although, you should note that soapy water can end up leaving a dull film on the countertop over time.
You can also use abrasive cleaners, scouring pads, and other abrasive scrub pads. Common kitchen and household countertop cleaners are safe to use when used normally; meaning when you spray the cleaner on and then wipe it off.
Prolonged exposure to many conventional household products such as bleach can discolor the surface of your Corian surface countertops. Also, window cleaners will leave a waxy film and should not be used when cleaning the counter.
Keep in mind that even though solid-surface countertops are very resistant to chemical damage, it is best to stick with pH neutral cleaners like granite cleaners, or those made for solid-surface. Corian is tough, but not impervious to stains or chemical damage.
High-heat and hot pans are like kryptonite to Corian. Unlike granite countertops or quartz, Corian is not very resistant to heat, and you cannot put hot pots or pans directly on the surface without risking a nasty scorch mark.
Placing pots and pans directly on your kitchen countertop, hot or not, is generally not a good idea with any countertop material.
Even with quartz or granite counters, it is possible that grit trapped under the pot may damage the surface and/or the surface could undergo thermal shock and then crack. It's rare but possible.
However, Corian surface kitchen countertops cannot withstand heat for long and will essentially melt or burn if pots and pans that are too hot are set directly on the surface, so always use a trivet.
A stain on a solid-surface countertop is rare, but no surface is 100% stain-proof. Most commonly, Corian solid-surface stains are actually spots resulting from chemical damage. Again, be a little picky about the cleaning products you use on your Corian countertops, or it may prove to be disastrous.
All cleaning products recommended here are pH neutral, safe and effective and ideal for use on Corian countertops as well as natural stone and quartz solid-surface countertops.
Scratches are another common occurrence because solid-surface countertops are relatively soft, which helps keep you from breaking dropped dishes but makes it easy to scratch from almost anything. Although, scratches can be sanded out in most cases.
To avoid scratches, always use a cutting board and trivet and refrain from sliding anything across the surface.
Dents aren't as common as scratches, however, but they definitely do sometimes happen if a heavy object is dropped onto the surface.
When comparing Corian versus granite countertops or Silestone, Corian falls short in the durability department.
Granite and quartz can take the heat and won't scratch or dent.
Granite can stain, but these stains can be prevented and removed.
Quartz can be chemically damaged, although it is rare, but is often permanent when it does happen. So, you will have to weigh all the pros and cons to get a better idea.
The good news is that most damage to Corian countertops can be repaired while damage to quartz often cannot be repaired.
The meaning and benefits of the term solid-surface become readily apparent when faced with a Corian countertop repair.
This countertop material is exactly the same all the way through the slab. If you chip or scratch ceramic or laminate, you will see that the inside color is different.
This is not the case with DuPont Corian countertops. You will find that the material is the same color and texture all the way through.
What this means is that Corian countertops can always be re-surfaced to eliminate scratches, scorches, and stains. Small dents can often be repaired as well.
Minor Corian repair is a simple DIY job often requiring nothing more than vigorous abrasive scrubbing or sanding.
Sanding out a scratch or blemish is a handy feature of Corian that is certainly beneficial. The only drawback is that in some cases, typically with deeper scratches, you may end up with a depression that may be visible and noticeable to the touch.
Still, it's nice to know that a simple procedure can fix a scratch and re-surfacing is always an option since the color is uniform through the entire thickness of Corian countertops and other solid-surface brands.
Corian offers a limited 10-year warranty. This sounds great except it only covers product defects which would be a very rare occurrence. And this must be determined by DuPont Corian.
Also, it does not cover staining or chemical damage, heat damage, scratches, dents or outdoor installations (UV rays can yellow or discolor Corian).
Anything that could happen during normal use is typically not covered by the warranty.
An example in the warranty states that if you happen to let a pan overhang the cooktop while heating, the radiant heat from the pan could cause a crack in the countertop. Well, this is not covered because it is considered negligence.
Same deal with leaving bleach on the surface too long. Diluted bleach can be used to clean Corian countertops, but it is not the best choice considering that if you fail to rinse the countertops well, or you accidentally spill a caustic chemical directly on the surface, it could discolor Corian.
The idea here is that the product is what it is. It is a solid-surface countertop that is resistant to damage but certainly can be damaged, so they offer no coverage for normal damages. Scratches, dents, and burns are not due to defects in the product.
No countertop material is completely impervious to damage. If you take the time to learn how to properly care for Corian, use common sense, and take reasonable measures to protect the surface (i.e., using cutting boards, setting hot pans on trivets, and using only pH neutral cleaners), then you'll easily avoid some of these more common problems.
The care and maintenance of a Corian countertop is essentially the same as granite or quartz countertops. So, for more Do's & Don'ts and general countertop maintenance information, visit the Care & Cleaning page.
Corian kitchen countertops may not be the most popular luxury choice, but they shouldn't be dismissed either. Corian offers a few very distinct advantages and features along with an upgraded and sophisticated style palette to provide plenty of design possibilities for your home.
DuPont requires all contractors that sell, fabricate, and install Corian to be certified because this goes a long way in ensuring a quality installation. So, you must find a certified contractor. Luckily, there are many dealers scattered all over the US and DuPont will help you find a Corian installer via their database.
Or you can go through Home Depot which carries Corian countertops, and you can arrange a certified installation from there as well.
