We focused on the following factors while testing the granite sinks for our research:

  • Build material
  • Aesthetics
  • Percentage of granite
  • Heat and Sound resistance
  • Damage absorption capacity

Additionally, we tried to find answers to the following questions to justify our claims further:

  • How easy they were to clean and maintain

Our priority was to figure out the additional benefits of composite granite sinks compared to ordinary ones. Our research found that most of the sinks were made out of 80% pure granite, making them natural germ killers and more hygiene.

We also found out that these sinks can stand up to 530-degree Fahrenheits of heat which can be a great addition to closed kitchen spaces.

Moreover, the sturdy build quality makes them sound resistant and increases shock-absorbing capabilities, making them more durable.

Compared to regular stainless steel sinks, the granite sink has several extra advantages, giving them the upper hand. The best part is even after having all these features, they do not compromise with aesthetics.

What to Look for Before Buying Granite Kitchen Sink?

grapite composite sink

Before we move into the reviews on our list, let’s learn about some of the factors that should come into play when purchasing a granite composite sink.


The first thing to consider is the durability of the sink. With that said, most sinks of this quality tend to last for quite a long time. If the sink has the necessary resistance features, you need to plan a good maintenance routine, and you should be good to go.

Number of Bowls

While some people want to keep things simple with single bowls, others might prefer to wash in one bowl and rinse in another one. So, it depends on whether you want the single bowl or the double bowl systems when it comes to these sinks.

Installation Type

The most common installation types are the overmount and the under-mount systems. This will also depend on the system you want to aim for. Go with the under-mount system if you don’t want the sink’s lip to be visible on top.

And if you want to stick with the easier-to-remove drop-in systems, then overmounted is the style that you should prefer.

Noise Elimination

Stainless steel sinks are notorious for loud vibrations. But the composite sinks come with extra noise elimination features that give you a quieter experience while working on them. So, pick out the sinks that offer this feature, and you should be good to go.

Frequently Asked Questions

1. What is the difference between an overmount and an under-mount sink?

This is a pretty common question for new buyers. Some sinks come with both mounting systems, while others will only allow them to mount in one way.

An overmount sink is more commonly known as a drop-in mounting sink. You can probably guess that you need to drop the sink into the countertop hole to install it.  A slight lip around the sink that keeps that sink on top of the countertop.

Under-mount sinks are installed beneath the kitchen countertop. Like the other one, you get a lip around this one, but in this case, the lip is hidden under the countertop on the other side of the spectrum.

2. Is there any difference between a granite sink and a composite sink?

The main visible difference is seen in the color and look of the two different sinks. Granite sinks are quite popular, but they are quite expensive too. They show off the natural patterns of the stone, and you can see how the stone looked.

When it comes to composite sinks, the color is seamless throughout the body of the entire sink. This adds a consistent appearance to the sink while keeping the durability intact.

3. Who makes the best granite composite sinks?

Many companies are now manufacturing these composite granite sinks, and the competition is undoubtedly high. But sinks from the Italian giants Kraus are miles ahead of the others regarding quality.

4. Are composite granite sinks any good?

Yes, if you talk about high-quality granite sinks, they’re constructed with high pressure. This makes the sinks nonporous, resistant to stains, heat, chips, and pretty hygienic.

5. Do granite composite sinks crack easily?

Unlike conventional stainless-steel sinks, composite granite sinks have a chipping history. But if you’re careful with the larger pans and pots, you can easily use them like regular sinks. Just make sure to get a high-quality one.

6. What is the best way to daily care for a granite?

Any sink should be sanitized daily since most households have a ton of food waste to wash. If you want to keep things clean and looking new, a dab of soap in a pot of warm water should be enough.

And if you want to stay on the safer side, using a swab with 70% isopropyl alcohol is a decent way to keep the sink lint-free.

7. What’s the best granite composite sink?

There really isn’t a quick answer for this. Brands like Kraus and Bianco have been making sinks like these for years. And they have built up fabulous reputations already. But the best one on our list is undoubtedly the number one choice from Kraus.

Final Words

With this thorough guide, you can find yourself the best granite composite kitchen sink. All five of the choices here are wonderfully packed with unique features.

You can get the best out of them only when you’re using them to wash your dishes. With the tight and nonporous construction, you can expect these sinks to last quite a while before you have a chance to buy another one.

So, pick anyone out of these, you really can’t go wrong with any one of these kitchen sinks.
