How Thick Should My Quartz Countertop Be?

When shopping for a new quartz countertop, you encounter many numbers, from the total cost to the square footage needed and the desired thickness. But what exactly does a 2cm (3/4”) versus a 3cm (1 1/4”) countertop mean? And why does it even matter? All of MSI’s quartz countertops are available in these two thicknesses, which impact not only the look but also their functionality. That extra half-inch can influence durability, weight, edging, and price. 

A 2cm countertop weighs less and is better suited for vertical applications since it may be more prone to damage. But, when the thinner quartz is used for your kitchen or bathroom counter, it adds a contemporary aesthetic thanks to the slimmer profile. The 3cm countertop withstands heavier weight because of the added thickness, so it’s the better choice for spaces that will see heavier traffic and use. However, since this classic natural stone countertop choice is heavier, make sure your cabinets, flooring, and foundation can support the extra weight. Keep this in mind when selecting your kitchen cabinets. 

When it comes to edges, many of the simpler choices can be used with either 2cm or 3cm sizes, but some of the more dramatic and ornate options may only be available for the thicker 3cm profiles. For countertops that appear extra thick, an additional quartz overhang is added, but the quartz slab itself remains either 2cm or 3cm thick. Remember to be careful with a 2cm countertop with exposed edges, as they bear less weight.

Using a lighter material can save you money because it uses less product and is cheaper to transport and install. However, remember that a 2cm quartz countertop may need extra plywood for support, which adds another step to the installation process.

Mara Blanca

Mara Blanca Quartz

Mara Blanca is a creamy quartz countertop with dark gray and tan veins and swirls similar to those found in a high-movement natural stone. The kitchen combines modern and traditional styles with a 2cm-profile quartz countertop featuring a standard edge, sleek stainless steel appliances and fixtures, and a classic white subway tile backsplash. The thinner countertop works well in areas with less traffic, but if you frequently place heavy items on your counter or have active kids, you might want to consider a thicker countertop slab option for added durability and peace of mind. 

Arctic White

Arctic White Quartz

Arctic White is a white quartz with no pattern or veining, which makes the solid color suitable for any style room. The waterfall edge introduces drama to this modern master bathroom, with the bright white countertop standing out against the dark, rich wood vanity. The 3cm-thick counter and additional waterfall edge add weight, helping to offset the wider installation of heavy-duty cabinetry. Initially, the 3-inch backsplash along the white wall may be overlooked, but the 2cm backsplash is ideal here, as it minimizes the use of valuable countertop space.    

Stellar White

Stellar White Quartz

Stellar White is a soft white quartz with subtle gray flecks that give the countertop character and dimension. It’s an ideal surface for sleek, modern designs like this heavenly yet futuristic white and wood-look tile master retreat. To achieve this extra-thick edge, extra quartz is applied around the perimeter of the 2cm countertop. Keep in mind that the seams will be visible with this look. Additionally, quartz's uniform pattern makes it easier to align the material, a task that is more challenging with marble countertops or other natural stones. 

Meridian Gray

Meridian Gray Quartz

Meridian Gray is a mid-tone gray quartz with subtle flecks for depth and interest. The neutral color palette suits many interior design styles, with cool grays enhancing the warm woods in this Scandinavian-inspired kitchen. You could try a different approach by mixing thicknesses. The 2cm countertop on the back wall contributes to a sleek look, while the thicker edge highlights the large island. 

Marbella White

Marbella White Quartz

Marbella White is another soft white quartz with soft touches of tonal veins and specks. Even though from far away it looks like a solid white countertop, the marble look quartz is an elegant choice for this contemporary chic kitchen. The double island has waterfall edges on both sections, but it has a more minimalist appearance due to the 2cm profile, unlike the chunkier edges usually seen. Keep in mind that for thinner countertops with an overhang for bar stools, reinforcement with plywood or another material might be necessary.
