Countertop Replacement Cost: What Kitchen Countertops Cost to Replace and Install

Average countertop replacement cost per square foot

Most quotes are built on square footage, so measure first. A standard 25-inch-deep base cabinet run gives a bit over two square feet of counter per linear foot, and an island adds its full top area plus any seating overhang. Measure your runs in inches, multiply length by depth and divide by 144 for a rough square footage.

Published ranges split the installed price into materials with delivery and labor to fabricate and install. Small jobs often carry a minimum charge, so a single vanity or bar top can cost more per square foot than a full kitchen.

What is the average cost to have quartz countertops installed?

Quartz usually costs $50 to $200 per square foot installed, about $1,500 to $8,000 for an average-sized kitchen (HomeGuide, 2023). The spread comes from slab quality: builder-grade quartz with a plain pattern sits near the bottom, while thick slabs with realistic marble-style veining sit near the top.

What is the average price of quartz countertops installed in a typical kitchen?

For 30 to 40 square feet, a mid-grade quartz usually lands in the middle of that range once cut-outs and edges are added. Quartz needs no sealing, which removes a recurring cost that granite and marble carry.

Countertop cost by material

Material moves the price more than anything else. These installed ranges are starting points for comparison, not quotes, and they overlap: a common granite and an entry-level quartz often cost about the same.

Is quartz cheaper than granite?

Not always. Entry-level quartz and common granite cost about the same, while premium quartz can cost more than standard granite. Over the years, quartz saves on sealing.

What else goes into kitchen countertop replacement cost

The slab and the install are only part of the price, and a clear estimate lists the extras separately so you can compare quotes fairly.

• Sink and faucet: a new undermount sink usually goes in with new stone tops, and the plumber reconnects the drain, supply lines and disposal.
• Backsplash: removing an old tile backsplash can damage drywall, so plan the new backsplash at the same time.
• Cabinet prep: stone needs a flat, solid base, and older cabinets often need shimming first.

Chicago-area factors that change the price

Condo buildings

Getting slabs to the kitchen is part of the job. Elevator size, stair turns and loading-dock rules can force extra seams or after-hours delivery, and some buildings ask for a certificate of insurance before any trade comes in.

Older bungalows and two-flats

Base cabinets and floors are often out of level, and walls are rarely straight. That shows up as extra leveling time and more careful templating.

Newer suburban homes

The common case is replacing builder-grade granite or laminate on cabinets in good shape, which keeps the scope simple.

Permits

A countertop swap by itself often does not need a permit, but moving a sink, adding an outlet or changing gas lines usually does. Rules vary by village, so confirm with your building department or the contractor before work starts.

How the countertop replacement process works

Most kitchens are without counters for a short window between tear-out and install, so knowing the sequence helps you plan.

1. Measure and estimateWe check the cabinets, walls, sink and appliances and give a written estimate.
2. Select the slabYou choose the slab or color; for natural stone it is worth seeing the actual slab.
3. TemplateAfter the old tops are removed or the new cabinets are set, the tops are templated on site.
4. FabricateCutting, edges and cut-outs usually take one to three weeks, depending on the shop.
5. InstallMost kitchens are set in a day, with seams joined using color-matched epoxy.
6. ReconnectThe sink, faucet, disposal and cooktop are reconnected, usually the same day or the next.

Ways to keep countertop costs down

The biggest savings come from slab choice and layout, not from cutting corners on prep.

• Keep the existing sink location to avoid plumbing changes.
• Choose a simple eased edge instead of an ogee or mitered edge.
• Use a remnant slab for a small island, bar top or bathroom vanity.
• Pick a mid-grade quartz or common granite color instead of an exotic slab.
• Combine counters, backsplash and sink in one project to avoid repeat trips.

What not to cut

Templating and cabinet prep. A top set on an uneven base can crack, and a poor template shows up as wide seams that are hard to fix later.
