How to Make a Quartz Countertop

Making a quartz countertop can transform the look of your kitchen or bathroom. With its durability, endless design options, and easy maintenance, quartz has become one of the most popular countertop materials. This guide will walk you through the process of selecting, fabricating and installing a quartz countertop.

Choosing a Quartz Slab

When selecting a quartz slab, you’ll first need to decide on the color and pattern you want. Quartz manufacturers offer a wide range of options including solid colors, speckled patterns, and veined looks that emulate natural stone. Some popular colors are white, gray, black and beige.

You’ll also need to choose the thickness. Standard thicknesses are 3/4″ and 1 1/4″. 3/4″ works well for most applications. Go thicker if you’ll have a lot of weight on the countertop like a commercial kitchen.

The slab size you choose depends on your counter dimensions. Common sizes are 115″ x 55″ and 130″ x 65″. Slabs can be cut down to fit your space. Keep seams and joints in mind when deciding on slab size.

Always select material from a reputable brand like Caesarstone, Cambria, or Silestone who offer warranties. Low-end quartz often cracks or stains.

Countertop Fabrication

Fabricating a quartz countertop involves carefully cutting and polishing the slab to your specifications. This is best left to professionals with specialized tools.

Here’s an overview of the quartz fabrication process:

  • Template the space – Your fabricator will come take exact measurements of your existing countertop and cabinets. This template guides the fabrication.
  • Cut the slab – Using the measurements, the fabricator will cut the selected slab to the shape of your countertop using a bridge saw. Holes for the sink and cooktop will also be cut out.
  • Polish edges – The cut edges are ground and polished to a smooth finish. Decorative edge profiles like bevels or ogees can be added now.
  • Inspect & finish – The fabricator will inspect the countertop, check fit, and apply final touches like grout line sealing. It’s ready for installation!

Installing a Quartz Countertop

Installing the countertop is the final step. Here is a simple overview:

  • Clean the existing cabinets and make sure they are secure, level, and plumb.
  • Set the quartz countertop in place. Have helpers to maneuver the heavy slab.
  • Apply a bead of silicone adhesive around the perimeter and any seams.
  • Carefully set the countertop down and press into the adhesive for a tight seal. Remove any oozing adhesive immediately.
  • Allow the adhesive to cure for 24 hours before use.
  • Seal around the edges with caulk for an extra water barrier.

Your sparkling new quartz countertop is ready to enjoy! Proper care means never using abrasive cleaners that can dull the surface. Just use mild soap and water to maintain the quartz’s beauty.

FAQs about Quartz Countertops

How much does a quartz countertop cost?

Quartz countertops range from $80 – $140 per square foot installed. The final cost depends on the quality of the stone, edge treatments, cutting complexity, and local labor rates. Expect to pay $2000 – $4000 for a medium sized kitchen.

What’s better – quartz or granite?

Quartz is engineered stone making it more consistent than natural granite. It’s also non-porous so it resists stains. Granite can be more heat and scratch resistant. Ultimately personal preference on looks and budget guides the choice.

Is quartz healthier than granite?

Some granites may emit small amounts of radon gas. Quartz is engineered without any radon making it a healthier choice. Neither material presents any serious health risks however.

How long does a quartz countertop last?

With proper care, a quartz countertop will last 15-25 years. The material is very resilient against scratches, stains and heat. But dropping very heavy objects can cause cracks.

Can you repair a damaged quartz countertop?

Minor damage like light scratches can be buffed out. But deep scratches, chips and cracks cannot be repaired in quartz. Seamless patching is impossible since slabs have unique patterns. Total replacement is the only option with substantial damage.

Should I seal my quartz countertop?

No, quartz does not need sealing. It is non-porous unlike natural stone. Sealing solutions may actually damage quartz and create a hazy film. Simply cleaning with a quartz-safe cleaner is all that is needed.


With the right quartz material, experienced fabricator, and proper installation, you can have a stunning countertop that will stay beautiful for years. Pay attention to the details in the slab selection and fabrication process. A high-quality quartz countertop elevates the look of any kitchen. Follow the care and cleaning guidelines to maximize its longevity. And enjoy all the benefits of quartz—durability, low maintenance, and timeless elegance.
