Many different materials are used for building kitchen sinks. However, most kitchen sinks come with many drawbacks. For example, the ever-popular stainless steel kitchen sinks scratch easily and loses their shine on repeated use. Porcelain sinks aren’t meant for the kitchen; cast iron sinks are heavy, while enameled sinks aren’t suited for harsh use.
However, the granite composite sink still remains one of the most popular types of kitchen sink. This is because they are very durable, easy to clean, modern, and, most importantly, beautiful. Granite composite sinks are made from a combination of granite stone dust and acrylic resin.

How to Choose The Best Granite Composite Kitchen Sink?
Before buying any granite composite kitchen sink, there are many important factors that you need to consider. Here are a few factors that can affect your buying choice.
1.Number of Bowls – Granite sinks mainly come in two bowl variations, namely the single bowl and double bowl variations.
- Single Bowl Sinks: As you might have gathered from the name, these sinks come with a single bowl where you have to place and wash your dirty dishes. These types of sinks are generally larger in size and ideal if you use many large pans and big-serving dishes. However, if you do wish to dedicate a separate space for keeping the dirty dishes and rinsing them, you can place a divider in the middle of the sink. These sinks are easy to install and have a single drainage hole. Also, they are very affordable and are the perfect option for people who can manage their space very well.
- Double Bowl Sinks: As compared to single bowl sinks, these sinks come with two bowls. Most configurations have one bowl slightly larger than the other. These sinks are very useful as they help you separate dirty dishes from useable sink space, making cleaning much easier. However, these sinks are much larger as compared to single bowl sinks. Moreover, they come with two drainage holes. The downside is that these sinks are difficult to install and costlier than standard single bowl sinks.
2.Mounting Style – The mounting style is how you need to attach the kitchen sink to your kitchen countertop. Granite composite kitchen sinks are available in three mounting styles.
- Undermount Sinks: Undermount sinks are one of the most beautiful and aesthetic sinks currently available on the market. These sinks attach beneath the countertop, which creates a very seamless look. As the lip of the sink rests under the counter, you get the maximum available counter space. Moreover, cleaning residue into the sink is much easier as well. As they are a beautiful and high-end option, they can easily boost the resale value of your house. Unfortunately, these sinks tend to cost more and are difficult to install.
- Topmount Sinks: Also known as ‘drop-in’ sinks, these sinks are directly placed into a cut-out in your countertop. As a result, there is a visible lip that rests on the counter. Here, cleaning is much more difficult as the dirt and residue might get caught at the edges of the sink. Taking a look at the advantages, these sinks are cheaper and are very easy to modify. In addition, replacing them is much easier as compared to undermount sinks.
- Farmhouse Sinks: Farmhouse sinks are a type of drop-in sink with a front side exposed. Also known as ‘Apron-Style’ sinks, these models have a very rustic look and come in a variety of colors. Moreover, you can customize the finish of these sinks as well. The downside of using these sinks is that they are more prone to chipping than the edge of the kitchen countertop.
3.Sink Size – Choosing the perfect size for your kitchen is something you need to look out for when hunting for a kitchen sink. The sink should be able to handle all your crockery needs while also complementing the beauty of your kitchen. Accordingly, you can choose a kitchen sink, from anywhere between 7 inches to 72 inches.
Single bowl sinks are smaller in size as compared to double bowl sinks. For a 150 square feet kitchen, a sink that is 24 inches wide will be perfect. However, if you do not cook much, standard kitchen sinks, usually 22 to 33 inches long, might be the better way to go. Moreover, you also need to pay attention to the scale of the design. For example, farmhouse sinks might not suit tiny kitchen sinks as they might overwhelm the entire room.
4.Price – Price is often the defining factor when it comes to choosing a sink. Generally, the larger the size of the sink, the higher is the price. Other factors that affect the price are the materials and the configuration that you choose. For example, most granite composite sinks are on the pricier side. Moreover, if you aren’t an avid cook, a standard sink size might just suit your needs.
