The thickness of countertops might be unusual to specify, but the right thickness will make all of the difference when it comes to durability and how long a stone lasts. Here is everything you need to know about the thickness of granite countertops.

Granite Thickness For Kitchen Countertops

If you have no idea what thickness is best for kitchen countertops, then it will be good to know that 2 centimeters or one-inch-thick countertops will do the job for you. Although, nowadays thicker slabs are more trendy and look more pronounced in the kitchen. But thicker slabs also mean that they will cost more than thinner slabs.

This is why one-inch slabs are the best general thickness of countertop slabs. It will be reasonable in cost and your kitchen will also look a lot more beautiful. Not to mention, this thickness is perfect for regular use as well.

Granite Thickness For Kitchen Islands

The thickness for kitchen islands is different than that for countertops. Kitchen islands are a very secondary addition to your kitchen and you don’t need to spend a lot of money getting thicker slabs for the island which will not be used as much. This is why the best thickness for kitchen islands ranges from 1/4th of an inch to ½ an inch maximum. You don’t need to be too elaborate with kitchen islands when it comes to choosing granite slabs of the right thickness. The mentioned thickness will do just fine.

Why Does Thickness Matter?

Here are some factors which are important to consider when you are thinking about the thickness of granite countertops for your kitchen.

More Durable

Granite is naturally a strong material, but the right thickness will also add to the strength of the stone. You might think that thicker means more strength but this is not always the case. The right thickness countertop is one that is not too thick and not too thin either. You want to select a slab with optimum thickness so that it will be a perfect fit for your kitchen.

More Expensive

As you increase the thickness of the granite slabs, the price of the slab will also go up. A thicker slab means more components are present in it and that component comes at a price. Not to mention, thicker slabs are also heavier and harder to handle, so the charges for installation will also be more. This is why it is recommended that you shouldn’t go too over the top with the thickness. The right thing to do is to select the right thickness which lies in the sweet spot for you and your kitchen.

For A Better Look

As mentioned previously, thicker slabs are getting a lot more popular these days. The bulky look of countertops is getting trendy and a lot of people gravitate toward this trend. The thing to look out for here is to not get too crazy with the thickness.

You can also make your kitchen look trendy with a reasonable two inches thick slab. There is no need for you to go over this. You will still get that pronounced and prominent look of the thick slab and it won’t cause a dent in your wallet, so it’s a win-win situation.

Granite Slabs Or Tiles?

Last but not least, you want to think about the cut of granite you want to get. You can either go for tiles or thick uniform slabs. The biggest advantage of slabs is that you don’t have to worry about seams, because there are none in them. With tiles, even though they are almost a fraction of what a slab would cost, there is going to be a problem with seams and gaps that need to be filled. So, you need to think about whether slabs are worth the price or if you want tiles in your kitchen.
