What Are Granite Composite Sinks Made Of?

Granite composite sinks are made from a mixture of fine granite sand and an acrylic resin bonding agent. Most manufacturers use 80% granite particles for the mix, while 20% is used as binding agents to create durability.

This process produces a material with many qualities as granite while offering better durability and easier maintenance. Granite composite sinks are also much more affordable than they used to be, making them an excellent option for any homebuyer on a budget.

Granite composite sinks are a relatively recent development in the world of kitchen sink making. Some manufacturers use granite, quartz, or other materials to create their style, trademarked and marketed under an individual name like Blanco’s Silgranit Franke’s Fragranite.

Best Granite Composite Sink Buying Guide

What Are Granite Composite Sinks?

Granite composite sinks are made of 70 to 80% crushed or powdered granite and 20-30% acrylic resin. They’re engineered stone, much tougher than regular stone while requiring less maintenance because they resist stains better than a counter ever will.

The surface of ordinary granite counters need sealant once every few months in order to keep the beautiful finish intact – but this would be disastrous for your sink, which takes more abuse on average than any other part of your kitchen.

Granite composite sinks are known for being non-porous and will not soak in anything. Their designs make liquids bead on the surface, so they stay dry all of the time. Manufacturers often treat their products specifically to enhance this feature, like adding materials that help repel water or by treating them with special coatings made from magic rocks called granite composite which also look beautiful.

You might find that some granite composite sinks are actually quartz composite. Despite the misleading label, it’s not false advertising because many of these sinks contain a component called “quartz.”

Quartz is just one stone in what we call “granite,” which has other similarities to this material. If you’re buying your sink and want something similar but lighter or quieter than traditional composites, consider getting a fiberglass shell with granite coating inside.

Things To Consider While Purchasing A Granite Composite Sink

Appearance, size, and shape

The look will depend on the style you prefer: modern or traditional style; color like white granite with other hues to pick from or metal finishes such as copper; patterns like an elegant design that is easy-to-clean but still looks good in a kitchen. Figure out what suits your preference best by identifying these three characteristics before shopping for one when choosing sinks at any store near you.

Noise elimination features

Are you tired of hearing the noise from your kitchen? The contemporary design of sinks eliminates the sounds of cracking pots and pans, giving you a noise-free kitchen. It is a vital feature to guarantee you have an environment conducive to cooking in your home. A variety of granite sink models are made with thick stone material, which makes sure that nothing interrupts when preparing meals or cleaning dishes.

Number of bowls

Your habits in the kitchen will determine how many bowls you need for your composite granite countertop. If you clean them with your hands, then get two different-sized bowl sinks to accommodate all of those dishes. You can quickly soak some while cleaning the others simultaneously.

However, a single bowl sink is better for those who have little space in their kitchen. The dishwasher can be more effective if you put pots and pans on one side while your dishes go through it as well. As an added bonus, they are usually cheaper than double sinks, which take up extra room to install.

Value for money

Cost is an important factor when purchasing anything. Fortunately, Granite composite sinks are a great bargain for today’s homeowners. They offer the beauty of stone without the cost and weight associated with other materials, coming in at an affordable price that will fit any budget.

Your sink is arguably the most important part of your kitchen. It’s where you wash dishes, prepare food, and much more. That means it needs to be durable enough to last a long time without any problems. Buying one with a warranty will give you peace of mind as well that you have a long-lasting unit.


Granite composite sinks are tough and can resist scratches, scuffing, and impacts. The uniformity of the material also means it will not chip like real stone. Granite composite sinks have excellent heat resistance.

Most manufacturers rate their sink to just over 530 °F (about 276 °C). Small chips or cracks may happen from heavy impact, but light damage is often repaired with an epoxy filler tinted to match the kitchen sink.

Maintenance and Cleaning Granite Composite Sinks

 best granite sinks

Unlike solid granite, composite granite is non-porous and easier to maintain. Elkay Quartz Luxe in Charcoal Bar Keeper’s Friend or Soft Scrub are suggested cleaners for stains on your sink as they’re safe but tough enough to do the job right. Wipe up any spills immediately after using the sinks, so you don’t have a messy water ring lurking around waiting for its chance at staining your beautiful new purchase.

Many granite kitchen sinks will also benefit from an occasional application of mineral oil. This is especially helpful with darker color sinks when it comes to maintaining deep blacks and browns.

These oils are available at your local grocery or hardware store, but you should always read the manufacturer’s care instructions before using them on any type of sink surface since some cleaners may mar a composite surface like that found in most modern kitchens today.

Granite Sink Cost

Most sinks range in price from $200 to $400 – this may seem like quite a bit, but it’s relatively affordable compared with other premium sinks options such as cast iron or fireclay, which can cost upwards of five thousand dollars.

Benefits of Granite Composite Sinks

Heat Resistant

Granite composite sinks are an excellent choice for the kitchen. Durable and heat resistant, they can withstand a steady stream of hot water without melting or cracking. The sink’s ability to stand up against harsh material gives you peace of mind while washing dishes in your own home. It also allows you to clean tough messes with minimal effort due to its high resistance levels – not even boiling water will affect it.

Resists Chipping, Staining, Scratching, Water Spots, and Acids

The washing area contains water, washing equipment gadgets, and detergents for cleaning purposes. Granite composite sinks can resist scratching by detergents chemicals. These items have a sturdy material that doesn’t chip when force is applied to them, so they’re perfect for those who use intense scrubbing on surfaces all day long.

Attractive & Durable

Granite Composite sinks are attractive and durable. They come in a variety of colors to choose from, improving the appearance of any room no matter how it looks now.

Drawbacks of Granite Composite Sinks

  • Granite is a sturdy and stylish material for sinks, but it does require more care than other types of the sink. 
  • Granite composite needs regular cleaning. Otherwise, they may begin to dull from being left in a dirty state for too long.
  • The installation requires extra support, unlike other styles.

While granite composite sinks do have some challenges, the benefits outweigh them. 

Types of Granite Composite Sinks

Depending on what is best for your space and sink, you can mount them in different styles with any installation type that suits both your needs and personal preference. To help you choose the style that best suits you, here are the details of various mounting styles and how they get installed.

Top-Mount Style

Top mount granite composite sinks drop straight down into place, making it much easier and comfortable to install. Unfortunately, with this style of sink, there is a higher risk that gunk will collect inside the rim on top due to lack of space for water drainage.

The install process starts by cutting the necessary hole in the countertop’s surface. The sink has a rim around its edge to help keep it secure and watertight, and silicone is used for a watertight fit and to caulk it in place.

Undermount Style

Under-mount granite kitchen countertops are attached from underneath using metal brackets or wood trim boards to provide additional support for the weight over time as well as an aesthetic appeal when looking at your beautiful new home’s clean lines.

Dual Mount Style

The sink comes with a flat rim, and you can install it either from above or below your countertop. The choice is yours. Except for the sinks containing quartz, dual mount sinks’ thickness depends on their material.

Farmhouse Style

Apron front sinks are also known as farmhouse sinks and usually compromise all the kitchen sink rage found in the industry. Unlike the traditional undermount or top mount styles, they feature a much deeper single large bowl design. If you want an eye-catching sink with plenty of space, this option is perfect for your needs.

The mounting style on these options typically happens below cabinet level, but it comes out exposed at its face, which extends past that surface slightly more than other types do (under-mounted and/or tops mounted). It has a unique look because of how it’s installed–the perfect choice if solid countertops suit your fancy.

Which type of installation style is better? From this question, it sounds like you are not only concerned with which will be cheaper or easier to install.

You want the best quality countertops for your kitchen space, and these two styles have different benefits in that regard: top mount counters offer a more seamless look between material and surface, while undermounts can create an interesting pattern on both sides when finished.

It’s difficult to say definitively which one looks better because they each have their advantages depending on what you’re looking for, though let’s see the differences:

Undermount vs. Top Mount Granite Sink

Top mount sinks are easy to install. They just slide into place, and then you can apply caulking for a tight and secure fit. These products are readily available and affordable. However, under-mount sinks come with their own set of challenges; they’re more complicated than top-mounted ones that require the help of an expert and are expensive because it’s not so easily found on store shelves or online shopping sites like Amazon®.

Additionally, these kitchen sink types don’t look that attractive due to exposed lips (which make them hard to clean) while also making countertops difficult during daily use in your home kitchen cooking experience since food tends to get stuck around the edges when washing dishes.

Sweeping food or any liquid directly into a top mount sink is difficult. Topmount sinks also take up more countertop space, which could have gotten used for other valuable things.

Under-mount sinks may not be hard to clean, but debris can get stuck where the sink and the countertop meet because their shape doesn’t allow liquids in from above, like with a traditional kitchen faucet. However, they do look lovely when installed and are good for aesthetic purposes.

Both sink styles have advantages over the other – some situations call for either style to come out as best-suited. You can install either of them depending on your preferences.

Frequently Asked Questions About Granite Composite Sinks

1. Is There A Difference Between a Granite Sink and a Composite Sink?

A granite sink is made of pure granite, while a composite one contains resin. Since the former comes in its natural color and unique by nature, manufacturers make composite sinks with various colors to appeal to more people.

2. Will Ammonia or Vinegar Harm a Granite Acrylic Sink?

The use of ammonia and vinegar is not recommended for cleaning granite acrylic sinks because the sealant will weaken over time. Using harsh cleaners quickens this process even more, so stick to milder detergents that leave less residue on your sink surface.
