  • Unique Look
    Granite composite sinks offer a truly rich and elegant look to any kitchen. They come with a myriad of different handles and hoses that add a unique look to your kitchen.
  • Very Hard And Durable 
    A granite composite material is harder than other sink materials. It can withstand a lot in a busy kitchen. You won’t have to worry about it breaking.
  • Heat, Scratch, And Stain Resistant 
    These sinks are resistant to almost any kind of damage. They can withstand moderate heat and won’t get scratched as easily as other materials since they are not porous.
  • Easy To Clean 
    Granite composite sinks are easy to maintain and clean. You can simply wipe them down with all-natural cleaning supplies.


  • More Expensive
    These types of sinks are more costly than other sinks, such as porcelain and stainless steel.
  • Harder To Install 
    They are more complicated to install than other sink models due to their weight and inflexibility.
  • Very Heavy/Requires Extra Support System
    Granite composite sinks are among the heaviest on the market. You will likely require assistance when installing your sink. You may also need extra support beams under the sink to hold up the weight.
  • Not Heat Proof
    While granite composite is heat-resistant, it is not completely heatproof. It can withstand temperatures from hot pots and pans, but it cannot withstand extreme heat.
  • Can Be Damaged
    If granite composite is not sealed properly, it could result in minor damage to the surface.

How Granite Composite Differs From Stainless Steel Sinks

Both of these types of sinks are among the most popular for modern and stylish kitchens. Stainless steel sinks are popular since it offers a bright sheen and durable surface. It is made of a slightly pliable and molded stainless steel material. But, which sink type is better for your kitchen?

Price Point

Stainless steel sinks are generally much cheaper than granite composite sinks. Granite composite sinks cost several hundred dollars depending on the type and model you buy. Stainless steel sinks cost much less on average. You can find a stainless steel sink for a hundred dollars or less.


Both of these kitchen sinks are durable and should last for years. Stainless steel is somewhat flexible, so it can retain its shape under stress. However, it can be prone to dents. Granite composite sinks are hard and can withstand drops easily.


You can clean a granite composite sink by using dish soap and a scrub pad. You may need to use vinegar to get rid of water spots. Stainless steel sinks should be cleaned with soft scrubbing materials since they are prone to scratches.


Stainless steel is a thin metal. If you move objects around in the kitchen sink, you may hear some excess noise. Granite composite absorbs sound since the material is thick and hard.


Both of these kitchen sink materials are convenient for homeowners. They require little maintenance and can be cleaned easily.

Ease of Installation

A granite composite sink is much harder to install due to its weight. You may have to hire a professional to help you install your new granite composite sink. Stainless steel is easier to install since it is lightweight. It will not require any additional support beams.

Granite Composite Sink Vs Stainless Steel

Granite Composite vs Other Materials

Granite vs. Quartz Composite Sinks

While both of these sink types are durable, granite composite tends to hold up better than quartz composite. They are both resistant to scratches and dents, but granite composite is more resistant to large cracks in the basin. Granite composite is unforgiving when it comes to your glass cookware due to its hardness.

Granite vs. Cast Iron Sinks

Both of these types of kitchen sinks can last for many years. A cast iron sink is very heavy and more difficult to install. These sinks are also expensive since they must be coated with porcelain and cured. If you get any chips on the surface of your cast iron sink, it can be prone to rust. Granite composite is rustproof.

How to Maintain a Granite Sink

These types of sinks should be coated with sealant every 3 months or so to protect them from damages. We recommend buying a granite composite sealant and coating the sink. Let it sit for a few minutes and rinse it off.

How to Remove Tough Stains

  1. 1
    Step 1: Sprinkle baking soda all around the surface of the granite composite sink.
  2. 2
    Step 2: Apply a small amount of white vinegar and let it react with the baking soda.

    Step 3: Scrub the sink using the mixture with a scrubbing pad

    Step 4: Once you have scrubbed the entire sink, rinse it with warm water and dry it with a towel.
