Quartz is the counter we sell most. It is also the one where two slabs can look almost the same in a showroom and still come from very different factories. Here are four things to check before you choose a brand, and what the makers of the quartz lines on our countertop page actually publish.
What quartz is
Engineered quartz is crushed natural quartz bound with resin and colored with pigment, then pressed into slabs. The quartz is what makes it hard. The resin is what holds it together and keeps spills from soaking in. Of the makers below that publish a figure, Wilsonart says its slabs are up to 93 percent quartz, and Caesarstone says up to 90 percent quartz minerals.
1. Is it listed for food contact?
NSF International certifies products against published standards. The one that applies to a counter is NSF/ANSI 51, which NSF describes as sanitation requirements for the materials used in commercial food equipment. It was written for restaurant kitchens, so on a home counter treat it as a strong extra rather than a must. A listing tells you the surface has been checked against that standard by someone other than the maker.
You do not have to take anyone’s word for it. NSF publishes its certified product listings, and you can look a brand up yourself. One tip: brands are often listed under the parent company, so Silestone appears under Cosentino and Hanstone under Hyundai L&C.
2. Read the warranty, not just the word “lifetime”
Three questions answer most of what a quartz warranty means for you:
- How long? Lifetime and 25 years both appear on the lines below.
- Does it stay with the house? Some move to the next owner if you sell, some shrink when they do, and some end with you.
- What do you have to do to keep it? Several of the warranties below ask you to register the counter within 30 or 60 days of install, and to have it cut and installed by a fabricator the maker approves. Miss that step and the warranty may not apply.
3. Who makes it, and where
A maker that puts its name on the slab and tells you where its factory is has something to lose. Most of the lines below say where they are made. Two of them, Wilsonart and Hanstone, also say their slabs are pressed with Breton technology, a vacuum and vibration process from an Italian equipment maker. The others do not publish how they press their slabs, which is not the same as doing it differently.
4. Be wary of a price with no name on it
A slab with no maker’s name, no warranty paper and no listing might be fine, but it takes real effort to prove it. Before you buy quartz from anyone, us included, ask for the maker’s name and a copy of the warranty.
What the makers publish, line by line
These are the quartz lines on our countertop page. We checked each one against the maker’s own warranty papers and NSF’s listings in September 2026. Warranties change, so read the current one for the slab you pick.

See it next to your cabinets
The same quartz color reads differently next to a white cabinet and a walnut one. Our Littleton showroom carries 123 manufacturers across cabinets, countertops, tile, flooring, vanities, fixtures and hardware, so you can hold the sample against the rest of the room in one place.
We always put the countertops in ourselves. We template, fabricate and set the tops, priced as a package with the slabs, even when you install everything else yourself or bring your own contractor.
Compare the slabs side by side.
Bring a cabinet door, a floor sample or a photo of the room to our Littleton showroom. We will help you compare the quartz lines on this page against it, then template, fabricate and set the top ourselves.
