Overview of Quartz Counters

Quartz counters are now the leading competitor to granite for upscale kitchen and bath remodeling and construction. Beauty and durability are combined in quartz counters. The material is easy to clean, and its non-porous surface doesn’t have the stain potential of granite.

Did you know that quartz is also called engineered stone? It’s made from 93% quartz chip and dust held together with polyester resin binders that are pigmented to give the countertop its color. The process gives manufacturers control of the color and appearance. Quartz countertop cost is narrower than natural stone, since there are fewer variables in pricing.

Here are average costs for common projects.

  • Average bathroom countertop: $650 to $1,075
  • Average kitchen countertops: $1,950 to $2,585
  • Kitchen countertops with island: $3,100 to $4,275

Check out material and installation cost factors next that will help you narrow the quartz countertop cost you can expect when you get estimates.

Quartz Slab Cost Factors

There are fewer variables with quartz than with granite and marble, but some material factors are in play. Others are related to how much fabrication work is done on the slabs and to installation difficulty.

  • Grade of the Quartz: There are three engineered stone grading levels: First quality or first choice ($80-$105 installed) has rich, deep color and consistency. Standard or commercial grade quartz ($70-$95) isn’t as deeply pigmented and has a higher ratio of dust to chips than first quality counters. Seconds or second choice ($55-$75) have the highest ratio of dust to chip, so are plain looking. Grade doesn’t affect strength or durability.
  • Slab Thickness: Slabs 1 or 1.2 centimeters thick are used to create a luxury look on the cheap. They aren’t strong enough for long-term use and should be avoided. Slabs 2cm and 3cm are preferred, with 3cm best for kitchens. Thicker material costs more.
  • Edge Cut: There are many edge styles available. The standard squared edge with slightly rounded corners is called “eased” edge. Complex double-bevel and ogee and similar cuts cost more. The more complex the cut, the higher the cost.
  • Number of sink Holes: Most countertops are estimated with one sink hole. To cut a second hole for a bathroom sink or prep sink in the kitchen will raise the cost.
  • Finish: Manufacturers make several finishes. Silestone, for example, offers polished, suede and volcano, a textured finish like lava stone. There might be some variation in cost based on finish.
  • Slab Size: Oversized slabs used for kitchen islands and peninsulas have a higher cost per square foot due to greater fabrication and installation difficulty.
  • Cost of Living: You’re probably aware whether costs in your area are low (rural, Midwest and South), high (East/West Coast, major metro areas) or average (everywhere else) compared  to other cities or regions of the country. That cost of living will affect quartz installation costs too.

Cost of Installation Supplies

The costs in the table above cover slabs, installation materials and the labor required. We’re simply itemizing the costs, so you know how your money is spent.

  • $45-$85 | The cost per square foot of just the quartz slab, with an average of about $60.
  • $15-$60 | Total cost of installing plywood on top of the cabinets or vanity for countertop support. Note: Most jobs do not require plywood, though some installers might insist on it. Ask for their reasoning.
  • $12-$25 | Countertop adhesive and caulk.
  • $7-$10 per linear foot | Optional edging applied to the bottom of the countertop edge to give it a thicker appearance. It’s always used on 2cm material and an option on 3cm counters.
  • $40-$75 | Rental of a wet saw for cutouts.

Permits, Inspection, , Related Costs and Installation Time

Permits and Inspection Cost

  • $0 | A permit isn’t required for kitchen and bath countertop installation, though of course they are needed for plumbing and electrical work done as part of the construction or remodeling.

Related Costs and Installation Time

While installation is included in most estimates and in our table above, here are labor costs for those considering a DIY project.

  • $85-$215 | Cost to remove and dispose of an existing countertop, if applicable.
  • $8-$15 per square foot | Installation labor cost. Specific cost depends on the size and number of slabs. If you get just installation estimates, expect about $175 for a single-slab bathroom counter or island and up to $300 for a single-slab kitchen counter. For two or three kitchen slabs and an island, cost will rise to an average of $750.
  • $90-$125 | Cutting additional sink holes. Price will exceed $200 if the edge must be polished for an undermount sink.

Countertop Install Time Schedule

Installation of engineered stone counters is quick compared with a concrete or tile countertop. Most is done by a two-person crew. A third person might be required for large slabs.

  • 1 hour or less | Remove the old countertop
  • 1-2 hours | Installation of a single slab counter
  • 3-6 hours | Installation of two or more slabs
  • 6-8 hours | Installations that include an island and/or additional sink holes

Quartz countertop installation has its challenges. The material is heavy and hard to handle. The underlying cabinet tops must be very level to prevent unsupported areas of countertop from cracking. Shimming the counters at low points is usually required.

Cutting quartz to compensate for a wall that isn’t quite straight or to create the edge you want is quite difficult. A diamond-blade wet saw technique is required. If those tasks lie within your skill set and you have the tools, DIY installation is possible.

Still, installation cost is just 10% to 15% of the job. You’ll incur 100% of the expense of fixing mistakes. So, we recommend pro installation.
