Granite Thickness: How Thick Should Granite Countertops Be?

Feb 26, 2018

One of the most common questions customers ask us is, “how thick the stone should be for their project?”


While 3cm stone countertops are thicker than 2cm countertops it does not necessarily mean they are superior – both have specific advantages. With proper care and maintenance, either thickness can work well. Let’s talk about the differences of 2cm and 3cm stone to help you determine which stone is best for you.

While you can most certainly use a 2cm stone for your kitchen or bathroom counter, we do not recommend it.  Since the 3cm stone is thicker than a 2cm stone, it is going to naturally be stronger, so it would work best for areas that see high traffic. Especially for something like limestone vanity tops or a marble counter, which are rather soft materials. Although the 2cm thickness is still stronger and more reliable than a bathroom vanity top made of artificial material is not as durable as the 3cm stone. And of course you want to have a granite countertop that will last you a lifetime, so durability is important.


However, this edge requires multiple seams, and limits the style of edge profiles you can choose from. Although this option may seem cheaper, it is substantially weaker than a 3cm stone, which may result in costing you more money in replacements and repairs down the road.

Another less durable method that many other countertop companies use is a laminate countertop, which consists of a very thin stone wrapped around a piece of wood. This method is much weaker than a solid slab of natural stone and restricts what you are able to do stylistically.

For example, a laminate countertop is not able to curve, meaning that you will be stuck with pointy corners, which can be dangerous and unsightly. There are a very limited amount of colors to choose from as well. The wood filler will also warp over time. Plain and simple, these stone veneers do not offer a long-term countertop solution.

For more decorative uses of natural stone, such as fireplace surrounds, coffee tables, shelves, and frames – a 2cm stone can be perfect. The 2cm thickness allows for the same beautiful aesthetic as the 3cm, but for a slightly cheaper cost and less weight. This is perfect for those who like to rearrange their space often, or would like to spruce up their décor without breaking the bank.
