Granite Composite vs Stainless Steel Sinks: 4 Key Differences

granite composite sink vs stainless steel
Written by Jenny Molin

A kitchen is what makes a home complete, while a sink is one of the many essentials that make the kitchen whole. What use is a kitchen without a functioning sink, right?

It’s vital to have a sink that does its job for you very well. The most popular types are the granite composite sink and stainless steel sink.

Don’t know how to differentiate them? Fret not! Read our in-depth comparison on “Granite Composite vs Stainless Steel Sink” to find out what you need to know when comparing granite these two options.

Granite Composite Sinks: Pros & Cons

Granite Sinks vs Stainless Steel Sinks


  • Long-lasting
  • Offer great resistance against scratching and chipping
  • Endure heat (up to 530° Fahrenheit) and pressure
  • Retain their natural color and texture
  • Easy to clean. You don’t need additional chemicals for cleaning, unlike other sinks
  • The composition of granite and acrylic resin makes them less expensive than natural stone


  • The stone material makes them heavier than other types. These bulky sinks require a better support system with annual sealing.
  • Granite restricts them to matte finishing. If you like shiny finishing, you would have to look at other options.
  • More expensive than stainless steel and ceramic types.
  • Need more maintenance than others, requiring close attention to last longer.

Stainless Steel Sinks: Pros & Cons

Stainless Steel Sinks


  • Durable, rust-free, chip-and crack-resistant
  • Much more versatile than sinks made of other materials
  • Available in contemporary styles and several sizes
  • Come in both matte and shiny finishing, and maintain that look for several years
  • Have many configurations
  • Survive against brutal scrubs and heaviest dishes
  • Their surfaces are easy to clean and don’t decolorize
  • Cheaper than granite composite sinks
  • Installation at a very reasonable price


  • Cause a disturbing noise when something is dropped on the body, even with the damping pad underneath
  • Unreliable quality sinks are vulnerable to dents
  • Vulnerable to scratches
  • Easily deformed by abrasive cleaners
  • Don’t fit in an uptight kitchen scenery. Most people don’t prefer them for elite décor

Granite Composite vs Stainless Steel Sinks: What’s the Difference?

1. Durability

Granite composite sinks are durable and better in the long run. This material helps withstand chipping, scratches, high temperature, and pressure.

Moreover, the uniqueness of the coloring and texture is identical. They won’t discolor unless bleach or ammonia is used. It’s a common material for undermount sinks.

However, stainless steel sinks can last for 15-30 years. They are chip-and-crack-resistant, and won’t tarnish or rust.

However, they could get scratched, so be a little cautious when placing items in the bowl. Staining liquids won’t discolor their surface finishing for years.

2. Noise Level

Composite bowls make less noise than other types. The granite and acrylic resin blend make them relatively silent than stainless steel.

These are hard and inflexible because of the stone composition, resulting in no vibration and lesser noise.

On the other hand, steel bowls are flexible. They comprise cheap thinner sheets. When water falls onto these sheets, vibrations occur and, therefore, noise.

Nowadays, the more common 16-18 gauge sinks are relatively harder and less flexible. They cause less noise but still lose the battle against others.

3. Cost

The composite sinks hold an uptight status. They have unique coloring and texture, and they endure scratch, chipping, pressure, and heat.

All their traits fulfill the needs of the high-end kitchen setup. This is the reason they cost more than steel basins. The cheapest ones might come in below $100.

In contrast, stainless steel sinks are commonly used because of their longevity. These bowls have fewer coloring options.

As steel is less expensive than granite, they are more economical and accessible to all, coming at just $50.

4. Maintenance

Composite sinks usually need more maintenance than others. The best option is gently clean them frequently.

Although they resist scratching and chipping, you should still refrain from using abrasives like bleach and ammonia. Use a fiber cloth soaked in hot soapy water to clean.

Steel bowls might get little hairline scratches over time, so use a wire-wool brush. Use baby oil to polish the surface.

In order to remove the water smudge stain, soak the stains with vinegar or rubbing alcohol for 3-4 minutes and then clean them with a rag.

Waste Disposal Units and Spare Parts

Both granite composite and stainless steel sinks often come with additional spare parts for enhanced functionality.

A waste disposal unit is one of the accessories that help enhance its draining range.

It’s a kind of blender with sharp blades that cut the larger chunks of food into smaller pieces.

These pieces smoothly follow their way out through the drainage.

  Composite Granite Stainless Steel
Surface decolorized Only with ammonia and bleach
Makes more noise
Requires more care
Better for elite décor


Both these sinks have their distinguished qualities and it’s up to you which one to buy.

With these details in mind, you will definitely be able to make the best choice for your kitchen.


1. Are granite composite sinks any good?

Ans. They’re the most durable sinks available in a variety of styles and textures.

They’re resistant to scratching, chipping, staining, pressure, and heat. They can fit in a high-end kitchen as well.

2. Will my granite composite sink crack easily?

Ans. Although heat-resistant, they are vulnerable to cracks.

Sometimes, when they come in contact with extremely hot water or pan, they could crack. So, avoid putting hot materials in the sink.

3. Can I put bleach in a composite sink?

Ans. You can’t use bleach in a composite bowl unless mixed with water – the raw bleach results in discolorization.

To remove the most noticeable stains, mix half bleach and half water. Don’t use 50% bleach if the stains are light.

4. What’s better – granite sink or stainless steel?

Ans. Both have their own advantages and disadvantages. The granite ones are less apt to damage.

They are less noisy and less expensive than steel. But the steel bowls are easier to take care of.

They are noisy but comparatively cheaper.
