How Thick is a Quartz Countertop


Quartz countertops have become an increasingly popular option for kitchen and bathroom remodeling projects in recent years. Made from ground quartz crystals combined with resins and pigments, quartz offers an attractive, durable, and low-maintenance alternative to natural stone or tile countertops. When selecting quartz for your home, one of the decisions you’ll need to make is which thickness to choose. Understanding the standard thicknesses available and the factors that impact thickness selection will help you pick the right quartz countertop thickness for your space and needs.

Standard Thicknesses for Quartz Countertops

Quartz countertops are typically available in three standard thicknesses:

1. 3/4 Inch

This is the most common and affordable thickness for quartz countertops. At 3/4 inch thick, these countertops offer a slim profile and lightweight feel. The 3/4 inch thickness works well for applications like bathroom vanities or kitchen countertops in condos or apartments. This slimmer quartz profile limits overhang space without support.

2. 1 1/4 Inch

A 1 1/4 inch thickness provides a richer, more substantial feel underhand. The added thickness allows for more overhang space without requiring additional support. This makes the 1 1/4 inch thickness ideal for larger kitchen islands or sections that require greater overhangs. The extra thickness also gives the countertop enhanced durability and impact resistance.

3. 2 Inch

At 2 inches thick, quartz countertops start approaching the look and feel of full stone slabs. The 2 inch thickness can support overhangs exceeding 12 inches without requiring extra support. This ultra-thick profile delivers a smooth, robust appearance and unmatched sturdiness. However, the 2 inch thickness also comes with an increased price tag and total weight, making it less suitable for all applications.

Factors Impacting Quartz Countertop Thickness

When deciding which quartz thickness best suits your space, consider the following factors:

  • Use of overhang space – If maximizing overhang space for bar seating or design effects, opt for a 1 1/4 or 2 inch thick quartz countertop. The added thickness prevents sagging or cracking with longer unsupported spans.
  • Budget – Thicker quartz costs more due not only to more materials, but also increased fabrication time and transportation costs of the heavier slabs. If on a tighter budget, the 3/4 inch thickness can help control costs.
  • Cabinet depth – Make sure cabinet depths can accommodate the thickness desired. Especially with 2 inch quartz, cabinets must have adequate interior room to support the full top.
  • Appliance spacing – Similarly, factor in proper appliance clearance above thicker countertops. A 3/4 inch top may be needed to ensure wall ovens or other appliances fit.
  • Aesthetic goals – Thicker quartz countertops make a bolder visual statement, aligning more with a luxurious or traditional kitchen aesthetic. Slimmer profiles blend seamlessly into more contemporary or minimalist spaces.

How Thick is a Quartz Countertop: Key Takeaways

To recap key learnings on quartz countertop thicknesses:

  • 3/4 inch is budget-friendly and offers slim, lightweight profile
  • 1 1/4 inch provides enhanced durability for overhangs and visual richness
  • 2 inch is the thickest, most robust option but also costs more and weighs more
  • Consider overhang needs, budget, cabinet depths and appliance spacing when selecting best thickness
  • Thicker quartz creates a more substantial, stone-like look compared to thinner versions

Choosing the right thickness comes down to your functional needs and design preferences. Any of the standard quartz countertop thicknesses can provide an attractive, easy-care alternative to traditional countertop materials. By understanding the differences among 3/4, 1 1/4 and 2 inch options, you can confidently pick the ideal quartz thickness for your next remodeling or construction project.

Frequently Asked Questions About Quartz Countertop Thickness

What is the most popular quartz countertop thickness?

The 3/4 inch thickness is the most common and popular choice for quartz countertops. At 3/4 inch thick, quartz offers an affordable slim profile that works well for most applications.

Is 3/4 inch quartz too thin?

While thinner than other options, a 3/4 inch quartz countertop is not necessarily too thin for an effective and durable countertop in many situations. The 3/4 inch thickness can be completely suitable for applications like bathroom vanities or small apartment kitchens. Larger spans, overhangs, and heavy usage demand thicker quartz.

Can you get quartz thicker than 2 inches?

It is possible to get quartz fabricated at custom thicknesses beyond 2 inches. However, the 2 inch thickness is typically the maximum offered by most quartz manufacturers. Anything above 2 inches moves into a specialty slab range with exponentially higher costs.

Should I get 1 1/4 or 1 1/2 inch thick quartz?

The small difference between 1 1/4 vs. 1 1/2 inch quartz is negligible for most applications. Either thickness provides enhanced durability and overhang support compared to 3/4 inch. Opting for 1 1/4 inch will cost slightly less than 1 1/2 inch and is likely sufficient for most needs.

Is 2 cm quartz too thin for kitchen counters?

Two cm translates to roughly 3/4 inch, which is likely too thin for larger span kitchen countertops, especially those with overhangs. Two cm quartz can work well for bathroom vanities but lacks the sturdiness needed for heavy daily use kitchen counters. Go with 1 1/4 inch or thicker for kitchens.


Quartz countertops provide homeowners with an attractive, functional, and easy-to-maintain alternative to traditional countertop materials. Selecting the proper thickness impacts the cost, durability, and visual appearance of your new quartz countertop. Carefully examine the standard 3/4, 1 1/4, and 2 inch thickness options available to determine the right quartz thickness for your specific space and needs. With an understanding of the unique benefits offered at each thickness, you can confidently choose quartz countertops that align with your budget, kitchen or bath design, and how you plan to utilize your countertops.
