Quartz countertops are a popular choice for kitchen and bathroom remodels due to their durability, low maintenance, and stylish appearance. When selecting quartz countertops, one important consideration is the thickness. Here is an overview of the standard thicknesses available and what to consider when choosing the right thickness for your needs.
Standard Thicknesses for Quartz Countertops
Quartz countertops are available in three standard thicknesses:
This is the thinnest option for quartz countertops. At just 3/4 inch thick, these countertops have a slim profile that works well when you want to maintain the existing countertop height. 3/4 inch quartz countertops are lightweight and typically the most affordable option.
The downside is that 3/4 inch slabs are prone to cracking or chipping if not installed correctly or properly supported. They also can’t be polished on the edges. For these reasons, 3/4 inch quartz is best used for low-traffic areas like bathroom vanities.
1 1/4 Inch
The 1 1/4 inch thickness is considered the standard for most quartz countertop installations. At this thickness, the countertops are durable enough for high-traffic kitchens while still keeping costs reasonable compared to thicker options.
The 1 1/4 inch thickness allows for some overhang from the cabinet without needing additional support. The edges can be polished giving a finished, upscale look. This versatility makes 1 1/4 inch the most popular choice for both kitchen counters and bathrooms.
2 Centimeters (Approx. 3/4 Inch)
At 2 centimeters or around 3/4 inch, this thickness offers a slim profile while still providing more strength than a 3/4 inch slab. The added thickness provides better resistance to cracks and chipping.
The downside is that 2 cm quartz countertops cannot be extended more than 3 inches without requiring additional support. This limits overhang potential. The edges also cannot be polished due to the thinner profile. Still, the 2 cm thickness is an economical option for low- to medium-duty applications.
Factors to Consider When Choosing Thickness
When deciding which quartz thickness is right for your counters, keep the following considerations in mind:
Thicker quartz countertops can withstand more wear and tear. For high-traffic kitchens or commercial settings, 1 1/4 inches or thicker is best. For primarily decorative countertops like in a master bath, 3/4 inch could suffice.
If you plan to have your countertops overhang the base cabinets by more than 3 inches, you may need to go with a thicker slab for proper support. 1 1/4 inch or thicker is recommended for countertops with longer overhangs.
To get polished or mitered edges, you’ll need at least a 1 1/4 inch thickness. Thinner slabs cannot be given finished edges due to the slim profile.
As thickness increases, quartz countertop prices also rise. 3/4 inch options are the most budget-friendly, while 2 cm and 1 1/4 inch offer more durability for a moderate price increase.
The thickness of the slab impacts its visual appearance. A thicker quartz countertop looks more substantial and upscale. A slimmer profile has a lightweight, streamlined look. Choose based on your desired style.

- 3/4 inch is budget-friendly but prone to damage without proper support
- 1 1/4 inch is the standard thickness for most kitchen and bath quartz countertops
- 2 cm offers a slim profile with more durability than 3/4 inch
- Consider usage level, overhang, edges, budget and aesthetics when choosing thickness
Choosing the right thickness comes down to your budget, visual preferences, and how you plan to use the space. Consult with a countertop installation professional to ensure you choose a quartz thickness that provides both beauty and durability.

FAQ About Quartz Countertop Thickness
Here are answers to some frequently asked questions about how thick quartz countertops should be:
How thick are standard quartz countertops?
The standard thickness for quartz countertops is 1 1/4 inches. This thickness offers an ideal balance of durability and price for most kitchens and bathrooms.
How thick should kitchen quartz countertops be?
For kitchens, opt for at least 1 1/4 inches of thickness, or thicker if you plan on a longer overhang or need extra durability. Kitchen counters see heavier daily use, so a thicker slab is ideal.
What is the thinnest quartz countertop available?
The thinnest quartz countertops are 3/4 inch thick. This ultra-slim profile works best on vanities and decorative counters that won’t see as much wear. 3/4 inch thickness is not ideal for heavy-duty kitchen counters.
Is 3/4 inch quartz too thin?
It depends on the application. 3/4 inch can be too thin for kitchen counters or other high-traffic areas where the counters need to be very durable. But for bathroom vanities, 3/4 inch quartz can work well since the counters won’t be used as heavily.
What thickness of quartz is best for overhang?
If you plan to have more than a 3 inch overhang, go with a 1 1/4 inch or thicker quartz countertop. The added thickness provides needed support for an extended overhang.
Can you edge a 3/4 inch quartz countertop?
No, a 3/4 inch quartz countertop is too thin to be given a polished or finished edge treatment. You need a thicker slab, like 1 1/4 inches, to be able to have the edges shaped, polished, or mitered.
When selecting quartz countertops for your kitchen or bath, don’t underestimate the importance of choosing the proper thickness. Factors like your intended use, budget, desired overhang, and edge treatments should all influence your decision. Consulting a quartz countertop provider is the best way to ensure you get the ideal thickness to meet both your functional needs and design vision. With the right thickness, you’ll enjoy durable, beautiful quartz countertops that stand up well for years to come.
