Quartz Countertops Cost Calculator & Price Guide

Quartz countertops are engineered stone. Manufacturers grind natural quartz and bind it with resin and pigments, then press it into slabs. Because the slab is made in a factory, color and pattern are consistent, and the price depends more on brand, design, and thickness than on what a quarry happened to produce.

What you pay for a finished kitchen comes down to three things: how many square feet of counter you need, which quality tier the slab falls in, and how much cutting and edge work the fabricator has to do. The tables below split the cost along those lines so you can build your own estimate.

The quickest way to estimate is to start from the size of your kitchen. Slabwise groups kitchens by how much counter surface they have, and whether an island is part of the job.

To find your own square footage, measure each counter run along the wall in inches, multiply length by depth, and divide by 144. Standard base cabinets give a counter depth of about 25 inches including the overhang. Add an island and any backsplash you want in quartz as separate pieces, then total them.

An island changes the math quickly. It is usually one large piece, often with an overhang for seating, and it can push a kitchen into the next size tier even when the wall counters are short.

Per-square-foot prices make it easier to compare quotes, but sources quote them differently. Some list the slab tier only, while others give a fully installed rate.

By quality tier

Fixr sorts quartz into three tiers. Builder-grade slabs come in plain colors and simple speckled patterns. Mid-grade covers most of the popular designer lines, including many marble-look patterns. Premier quartz includes thick slabs, bold veining that runs through the whole piece, and limited collections from the best-known brands.

Installed rates

Slabwise reports a wide installed range of $50 – $150/sq ft, but says most homeowners land between $70 – $100/sq ft. That narrower band is a sensible starting point if you plan on a mid-range color and a standard edge.

Installation starts well before the crew arrives. The fabricator templates your counters, cuts and polishes the pieces in the shop, and then a crew delivers, levels, seams, and secures them. Sink and faucet holes are cut before delivery.

The two labor figures cover different scopes. Fixr lists installation labor on its own at $10 – $35/sq ft. Slabwise combines fabrication with installation, which may explain why its range of $30 – $50/sq ft starts higher. When you compare quotes, ask whether the labor line includes templating and shop fabrication or only the site visit.

Cutouts and edges

Every sink, cooktop, or faucet hole is a separate cut. An undermount sink also needs a polished edge around the opening.

Edge profiles are priced by the linear foot of exposed edge, not by area. A simple eased edge is usually included. Rounded and decorative profiles cost extra, and an ogee edge takes the most shaping.

The two sources below describe similar kitchens and still give different totals.

Fixr gives a single typical kitchen range with a midpoint, while Slabwise shows an average kitchen without an island. The gap may come from the counter area each one assumes, the quality tier built into the average, and whether removal of old counters and fabrication are counted. Regional labor rates may also play a part, since fabrication shops in high-cost metro areas tend to charge more for the same slab.

Several charges can appear on a quote beyond the slab and the cutting:

• Removal and disposal of existing countertops
• Plumbing disconnection and reconnection for the sink and dishwasher
• A new sink or faucet, if you are replacing them at the same time
• Backsplash in quartz or tile
• Extra seams or support brackets for long runs and large overhangs

Ask for each of these as its own line so you can compare one fabricator with another.

Quartz slabs are heavy and break if handled badly, and cutting them takes wet saws and shop equipment. Cutting engineered stone also creates fine silica dust, which OSHA treats as a serious respiratory hazard. For most homeowners, the practical role in a quartz project is measuring for a budget estimate and preparing the cabinets, then leaving fabrication and installation to a professional shop.

Before installation day, confirm that your base cabinets are level and solid. Fabricators often will not install on cabinets that rock or sag, and fixing them on the day can add cost.
