How Thick Should My Quartz Countertops Be?

Deciding on the right thickness for your new quartz countertops is an important consideration during the design process. The thickness you choose will impact cost, durability, and aesthetics. This guide will overview the typical thickness options for quartz and provide recommendations to ensure you select the ideal thickness for your needs and budget.

Typical Thickness Options

Quartz countertops are available in three standard thicknesses:

3/4 Inch

This is the thinnest option for quartz countertops. A 3/4 inch thickness works well for simple designs and smaller budgets. At this thickness, quartz provides an affordable alternative to more expensive natural stone.

A 3/4 inch quartz countertop offers these benefits:

  • More affordable than thicker options
  • Suitable for simple countertop layouts
  • Provides a slim profile that works in small spaces

However, the thinner profile has some drawbacks:

  • Prone to damage without proper support
  • Can crack if not installed perfectly level
  • Not the best choice for heavy use areas

1 1/4 Inch

A 1 1/4 inch thickness is the most popular choice for quartz countertops. This thickness provides an ideal balance of durability, functionality, and cost.

Benefits of a 1 1/4 inch quartz countertop:

  • Provides enhanced strength over 3/4 inch options
  • Resists cracking and warping
  • Withstands daily wear and tear
  • Works well for most kitchen layouts

The added thickness gives excellent durability while keeping costs reasonable compared to thicker options. This versatile thickness works well in kitchens, bathrooms, laundry rooms, and more.

2 Inch

For a luxurious look and maximum durability, a 2 inch thick quartz countertop is available. The extra thickness offers:

  • Highest strength and damage resistance
  • Minimal seams for a seamless look
  • Provides support for longer spans
  • Stands up to heavy duty use

The added thickness does come at a higher price point. But for high traffic areas that demand durability, the investment in a 2 inch quartz counter can pay dividends in reduced maintenance and repairs down the road.

Recommended Thickness by Location

Choosing the right quartz thickness depends on the location in your home and how the space will be used. Here are some thickness recommendations by location:

Kitchen Countertops

For kitchen counters that support appliances, hold dishes, and withstand meal prep, a 1 1/4 inch thickness offers the best functionality. This thickness stands up to heavy daily use while keeping costs reasonable.

For an exceptionally durable surface in a busy kitchen, upgrade to a 2 inch thick quartz countertop. Island counters and eating bars that won’t see as much action can be finished with a 3/4 inch thickness to save on costs.

Bathroom Vanities

In bathrooms, a 3/4 inch quartz vanity top provides an easy-to-clean surface at an affordable price point. Quartz resists moisture damage better than many materials, making it an ideal bath vanity choice.

Laundry Room Countertops

With potential appliance vibrations and dampness in laundry rooms, a 1 1/4 inch quartz counter is the best choice. The added thickness prevents cracking that can occur near running appliances.


A 3/4 inch thickness works great for quartz backsplashes. The thinner profile delivers an attractive focal point without the higher cost of thicker quartz.

Other Considerations

Here are a few other tips when deciding on the right quartz thickness:

  • Consult your installer for advice on thickness based on cabinet type and layout.
  • Thicker quartz can support longer spans between cabinets or brackets.
  • Inspect the condition of existing cabinets prior to install. Thicker quartz can hide cabinet flaws better.
  • Choose thicker options for heavy duty tasks like rolling dough or chopping.
  • Consider rounded edges for a softer, safer profile on thicker counters.


When selecting your quartz countertop thickness, assess your space, usage, and budget. While thinner 3/4 inch quartz delivers value, most homeowners will benefit from the durability and versatility of a 1 1/4 inch thickness in moderate to high traffic areas. For luxury and strength, upgrade to a 2 inch thick quartz counter. Following the recommendations by location provided here will help you choose the ideal quartz thickness for each space in your home. With the proper thickness selected, you can enjoy beautiful, functional quartz countertops for years to come.
