Granite Kitchen Sinks

Quartztone Granite Sinks

Our cutting-edge Quartztone sinks are three times harder than natural granite stone sinks. Each quartz composite sink is crafted out of 80% quartz fused to 20% high-grade acrylic, resulting in an exceptionally durable and 100% sealed, pore-free surface that is hygienic and highly resistant to cracks, scratches, and stains. We also integrate silver ions with antimicrobial properties that help to reduce the spread of germs. Rugged, colorfast, and silky smooth to the touch, our Quartztone sinks deliver everything you love about natural granite with plenty of exciting upgrades.

Care & Maintenance

European Designs & Peerless Craftsmanship

We’re pleased to offer the beloved look of granite with contemporary designs and distinctive colors. Beyond their exquisite beauty, our Quartztone granite sinks are built to last a lifetime. These heavy-duty sinks are remarkably tough, and they are UV-resistant and able to withstand temperatures as high as 500 °F. Fall in love with our elevated take on the classic granite aesthetic.


Should I choose a topmount or undermount sink?

Both styles offer their own unique benefits.

  • Quartztone topmount sinks tend to be easier to install, and they have a lip that sits on top of the countertop that protects its edges from wear and tear.
  • Quartztone undermount sinks attach to the underside of the counter, and they have a seamless transition to the countertop, which allows you to easily push countertop debris over the edge and into the sink when you’re cleaning up.

What colors do granite sinks come in?

Our Quartztone sinks come in six fresh, colorfast hues: cloud, earth, midnite, mocha, taupe, and sand.

What kind of maintenance is required to keep my quartz composite sink in good condition?

For basic cleaning, simply wipe the sink down with a damp cloth and dry it with a soft cloth. After using your sink, rinse it with warm water and mild soap and wipe it dry. To clean minor mineral deposits or stains, use a mild vinegar and water solution and then rinse it with water. For tough stains, use a mild, non-abrasive cleaner or a 50/50 water and bleach solution. Do not use abrasive cleaners, strong chemicals, scouring pads, or steel wool. Learn more about sink maintenance.

Do your granite sinks include a warranty?

Yes, they are backed by our Limited Lifetime Warranty.
