The most common material thicknesses are 2cm and 3cm.
Common granite countertop thickness.
Three centimeters is the preferred thickness for both quartz and granite countertops for most countertop fabricators designers and architects.
So let s go over standard granite countertop thickness.
How much do standard granite slabs weigh.
Granite and marble countertops that are 3cm thick are strong enough to support their own weight when installed on cabinet bases.
Let s first begin with the two most common thicknesses utilized as it relates to stone countertop installations.
Quartz countertops are most commonly 2 or 3 centimeters.
It offers the most durability size flexibility and color options.
Obsessing over thickness of countertops granite typically comes in two different widths a slab or a 1 slab.
While there is a 20 40 difference in material costs between the two 2cm tends to be utilized for backsplashes or surfaces that won t be placed under stress regularly like a counter would be.
The table below lists the standard weights of the two slab options.
Countertops that are 2cm thick usually are installed on a 3 8 plywood decking to increase its strength and resistance to weight.
While inch thick granite countertops are typically seen in bathrooms you can install them in the kitchen as well.
The industry standards for countertops usually lean towards 3 cm natural stone.
Marble countertops that are 2cm are more prone to breakage because it is a softer stone.
There are benefits to both options and your decision should ultimately depend on the application of your slab.
In terms of design quartz countertop thickness definitely makes a difference.
Consider for example that thin granite tiles may be approximately 3 8 inch thick while the typical kitchen countertops may be between and 1 inches thick.
You have two standard options for granite thickness 1 two centimeter 2 cm granite slabs were the previous industry standard.
The thinner tiles may be more prone to cracking if something drops on them than the thicker slabs.
If you re looking for something thicker you ll likely end up with two slabs glued together which you most certainly don t want.
These are both thick enough to remain stable without as much support from the foundation beneath the countertop though 3 centimeters has become the industry standard.
And while some still argue in their favor 3 cm thickness has become the new standard for kitchen countertops and most other applications.
