How to Make Quartz Countertops Look Thick

Quartz countertops are a popular choice for kitchen and bathroom remodeling projects because of their durability, low maintenance, and stylish appearance. However, some homeowners find that standard quartz countertops look too thin for their liking. Luckily, there are several techniques you can use to make your quartz countertops appear thicker and more substantial.

Choose a Thicker Slab

The easiest way to make your quartz countertop look thicker is to simply select a slab with a thicker dimension. Standard quartz slabs are usually 1.25 inches thick, but thicker options are available. Going with a 1.5 inch or 2 inch thick slab will immediately give you the look of a more substantial countertop. Just keep in mind that thicker quartz slabs come at a higher price.

Add a Thicker Edge Profile

Another way to make your quartz countertop look thicker is to choose a thicker edge profile. The edge is what wraps around the perimeter of the countertop, and it can make a big difference visually. Rather than a standard pencil edge, opt for an eased, beveled, or ogee edge. These edges range from 1/4 inch to over 1 inch thick. A thicker edge profile will make the overall countertop look much more robust.

Use Thicker Backsplashes

Integrating a tall backsplash onto your countertop is another technique for making it appear thicker. Standard backsplashes are only 4 inches tall, but you can find quartz backsplashes up to 8 or 10 inches in height. By selecting a backsplash that covers more surface area, you enhance the thick, built-in look of the countertop.

Add Accent Strips

Gluing additional strips of quartz onto the front edge of the countertop creates instant visual thickness. These horizontal accent strips can be 2-3 inches wide to really bulk up the look. They should be made from the same quartz as the countertop for cohesion. Accent strips with attractive etched or textured patterns will be even more eye-catching.

Increase the Apron Size

For a kitchen island or peninsula with a front apron, enlarging the size of the apron is an easy way to make the overall countertop appear thicker. Standard aprons are usually just a few inches wide. For a thicker look, extend the apron to at least 6 inches or up to 12 inches wide. This will make the countertop seem deeper and more substantial when viewed head-on.

Use Thickened Corners

Adding extra thickness to the corners is another quartz countertop technique for creating the illusion of a thicker slab. Thickened corners involve mitering and gluing an additional piece of quartz on the corner to bulk it up before the edge profile is added. This makes the edges at any adjoining countertops or walls appear wider.

Add Side Returns

Side returns, also called side splashes, provide the same visual impact as thickened edges. They are essentially extended pieces of quartz that get attached to the sides of the countertop. Side returns can be just a few inches tall or go all the way to the bottom of the upper cabinets for a true thickened edge.

Increase Surface Area with Cutouts

For a homemade look, you can make simple cutouts along the front edge of the countertop. These small notches work to increase the visible surface area and make the entire countertop seem wider and thicker overall. The cutout spaces can also provide convenient gripping points.

Opt for Contrasting Thickness

Playing with contrasting thicknesses is a clever optical illusion technique. For example, pairing a thinner island countertop with thicker surrounding countertops can make the island seem daintier. Or, use a thinner countertop in a bold tone next to thicker white countertops to achieve a sculptural, substantial look.

FAQ About Making Quartz Countertops Look Thicker

Can you make a quartz countertop thicker after installation?

No, the thickness of a quartz countertop cannot be altered after it has been fabricated and installed. The methods for making a quartz countertop look thicker need to be planned prior to installation.

Does a thicker quartz countertop cost more?

Yes, a thicker quartz slab does come at a higher material cost, often priced per inch. Expect to pay 20-50% more for a 1.5 inch thick slab versus a standard 1.25 inch slab. Going up to a 2 inch thickness increases the price even more.

Do thicker quartz countertops look better?

It’s a matter of personal preference, but many homeowners do prefer the appearance of a thicker quartz countertop. They can look more massive, robust, and high-end. Just keep in mind that thinner countertops work well for smaller kitchens.

Can you put a thin slice of quartz on top of another countertop?

Yes, it is possible to adhere a thin slice or strip of quartz to an existing countertop surface. This can add stylish detail and the appearance of thickness. Professional installation is strongly advised for this type of quartz countertop overlay.

Should I get an undermount or topmount sink with a thick quartz countertop?

With a very thick quartz countertop, a topmount sink is recommended. An undermount sink could end up being uncomfortably deep. The topmount installation will avoid this issue and allow the sink to sit higher.

Is there a thickness limit for projecting or overhanging quartz countertops?

It depends on the specifics of the installation, but most experts advise against overhangs beyond 6-8 inches with standard 1.25 inch quartz slabs. Going up to a 1.5 inch thickness offers more strength and overhang possibility. Overhangs beyond 12 inches are not recommended.


With the techniques outlined above, it is certainly possible to make any quartz countertop look and feel thicker. Focus on visually bulking up the edges and surface area for the most impact. Be sure to communicate your goals for a thicker aesthetic to your countertop fabricator early in the process. And don’t be afraid to play with combining several methods to take your countertop’s thickness to the next level. Thinking strategically will go a long way toward creating quartz countertops with the substantial, premium thickness you desire.
