5 Common Quartz Composite Sink Problems

The world of kitchen sinks is massive – there are dozens of materials, brands, styles, colors, designs, and price points. With so many choices, selecting the perfect fit can be overwhelming.

So, maybe you decide to start by choosing a material. As you browse, you come across quartz composite. But before you commit to this particular material, you decide to check for common problems with these sinks. After all, who wants to deal with a finicky sink that comes with a crop of problems? Not us!

If you’re debating the merits of quartz composite sinks, you’re in the right place. This article breaks down a few of the common problems, so continue reading to learn more!

What Is A Quartz Composite Kitchen Sink?

Quartz composite sinks are made of crushed quartz and acrylic resin. Generally, these sinks feature a high percentage of crushed quartz, usually around 80%, while the last 20% consists of acrylic resin. The resin helps bind the stone particles together, creating a strong and durable finished result.

Unlike natural quartz sinks, these sinks boast a consistent, even color. So, if you like the look of natural quartz, with the patterns, veins, and color variations, quartz composite might not live up to your expectations.

Pros And Cons

Like any kitchen sink material, quartz composite has a few ups and downs. As you browse for the perfect kitchen sink, it doesn’t hurt to weigh the pros and cons. So, without further ado, here are a few pros of these sinks:

  • Highly durable
  • Heat resistant
  • Hygienic, non-porous surface
  • Stylish, modern designs
  • Various color options
  • Long-lasting
  • Easy to clean

On the flip side, here are a few potential drawbacks to consider:

  • Pricey compared to other materials (like stainless steel sinks)
  • Requires daily cleaning to avoid problems (like stains)
  • Even coloring might not fit every preference (if you’re hoping for a natural quartz look-alike)

1) White Film

Like granite composite sinks, quartz composite sinks are susceptible to a whitish haze. These sinks can form a filmy layer over the surface, creating a cloudy appearance. While this is more noticeable with dark-colored sinks, you might notice it on lighter-colored sinks as well.

The film develops as a result of mineral buildup. If you have struggled with hard water issues in the past, you’ve probably seen the work of mineral buildup elsewhere. For example, you might notice chalky whitish-yellow deposits around the base of your faucets, or you may notice gunk on the end of the spout.

Unfortunately, your faucets aren’t the only fixtures that will likely experience the adverse side effects of hard water. If you notice a white haze over your sink, it’s probably hard water deposits.

Thankfully, getting rid of these pesky deposits is doable. You’ll need white vinegar and patience, but the deposits should lift after a bit of soaking. Once you get rid of them, keep them at bay by drying out the sink after each use.

The deposits form when water pools in the sink and evaporates, leaving behind the minerals in the water. Over time, they build up, causing a film in your sink. So, by drying the sink after each use, you can avoid the problem altogether. Of course, you could invest in a water softener for your home (or faucet), but that can be a costly solution.

2) Stains

Although quartz composite is highly resistant to most stains, it can be susceptible to certain stains. For example, if you leave acidic and pigmented foods and drinks (such as tomato juice) on the bottom of your sink, you might notice discoloration after wiping it away. In addition, caustic chemicals can leave discolored marks on the sink.

So, following the care instructions that come with your sink is essential. These instructions usually warn against using harsh chemicals on the sink and advise against leaving pigmented food and drink on the sink’s surface.

If your sink stains, you can usually remove it with a bit of elbow grease and the help of natural cleaners. However, since these processes can take a while, it’s best to avoid the problem in the first place.

3) Cleaning Requirements

As mentioned, using harsh chemicals on your quartz composite sink can lead to discolored marks. So, you must be careful about what you use to clean the sink. For some folks, this can seem like a hassle, as you can’t grab any cleaner and scrub the sink with it, so it might seem like a high-maintenance sink.

However, while these sinks have special cleaning requirements, the cleaning process is simple. The best way to clean these sinks is with warm water, a soft cloth, and mild dish detergent. That’s all you need. Avoid commercial cleaners packed with strong chemicals and stick to gentle cleaners designed for quartz composite.

In some cases, cleaning your sink with the wrong material (like harsh chemicals) can void your warranty. So, save yourself the headache and steer clear of the powerful chemical cleaners at your local grocery store (for cleaning your sink, anyway).

4) Weight Demands

Like their natural counterpart, quartz composite sinks can be hefty. Although some sinks are fairly lightweight and don’t need any extra support in the base cabinet, some quartz composite sinks can weigh over 40 pounds. Without an additional support system in the base cabinet, the sink could place excessive stress on the countertop.

Over time, the constant stress due to the sink’s weight could cause it to pull away from the countertop altogether. Since the sink falling through the countertop isn’t ideal, it’s best to install the proper support system right off the bat.

This isn’t a deal breaker for many folks, as installing the support system is usually fairly straightforward. You can always hire a professional if you don’t know how to install the proper support system.

5) Chips And Cracks

There’s no doubting the inherent durability of stone. While much of this durability is transferred over to composite sinks, they can chip and crack from time to time. Chips and cracks in these sinks aren’t necessarily common, but since they do happen, it doesn’t hurt to mention the possibility.

The damage usually occurs as a result of dropping heavy pots or pans in the sink. The weight of the cookware can cause small chips and cracks upon impact, although it’s relatively uncommon that this will cause significant damage.

Luckily, if your quartz composite sink does chip, you can probably repair it. Small cracks and chips are easily repairable with an epoxy mixture, which you can buy at most hardware and home improvement stores. You simply need to color-match the epoxy to your sink and follow the instructions on the package for repair.

Is A Quartz Composite Sink Worth It?

So, with all of these issues in mind, is a quartz composite sink worth it? While it would be easiest if we could give a yes or no answer, the decision falls to you. From our research, we think a quartz composite sink is an excellent choice, despite its problems.

These sinks are durable, long-lasting, and a beautiful alternative to natural quartz. And considering most of the common problems are avoidable or repairable, these sinks are well worth it.

That said, the decision is ultimately yours. So, if you don’t like the idea of daily cleaning or installing extra support, a quartz composite sink might not be the best fit for your home. Or, maybe you love the benefits of quartz but can’t justify the cost. In that case, a quartz composite sink is an excellent choice.

So, while these sinks might be the perfect fit for some homes, they’re not the best choice for others!

How Long Do Quartz Composite Sinks Last?

With proper care and maintenance, a quartz composite sink can last several decades, if not longer. These sinks are exceptionally durable, so as long as you take care of them, they can last a lifetime.

Of course, poorer quality products with a lower quartz content usually are less durable than those with a higher quartz content. So, if you decide to purchase a quartz composite sink, look for one with a higher percentage of good-quality quartz without unnecessary fillers.

Is Quartz Composite The Same As Quartz?

As you browse for a new sink, you’ll probably come across quartz and quartz composite. Although the names are similar, these two materials are very different. While quartz composite consists of crushed quartz and resin, a quartz sink consists of natural stone.

Because of this, quartz sinks tend to be much pricier than quartz composite, as they’re made of solid, natural quartz. If you appreciate the durability of quartz but don’t want to pay the steep price tag, a quartz composite sink is an excellent alternative.

How Much Do Quartz Composite Sinks Cost?

On average, quartz composite kitchen sinks cost between $250 and $600. You might find these sinks at lower costs, but the good-quality options usually fall within this range. On the flip side, you might discover higher-end luxury-style sinks that cost more than $600.

Do Quartz Composite Sinks Show Scratches?

Given the inherent durability of quartz composite, these sinks are decently scratch resistant. Although the possibility of scratches is there, it’s not overly common to see, as you’ll have to exert quite a bit of force to leave a noticeable scratch.

If you accidentally leave a large scratch or hairline crack on the surface, you can always fill it in with epoxy. This can help the scratch blend into the surface, creating a more seamless appearance. Of course, you’ll need to color-match your epoxy mixture, or it’ll stick out like a sore thumb!
