Choosing the correct thickness for your kitchen or bathroom countertop can feel like a minor decision, but in fact, it is one of the most important decisions you will make when selecting new granite or marble countertops.
Most limestone slabs can be found in either 2cm (3/4") or 3cm (1-1/4") thick. Slabs which are 3cm thick are a much better value ultimately compared to 2cm slabs.

Along with these technical reasons, the 3cm substance has a better-looking border because the profile could be manufactured using more detail without needing to laminate the border.
A laminated border is where a thin strip of the exact same substance is put under the outside of the countertop until the profile is trimmed. This therapy can be used frequently on 2cm countertops to create them look thicker; however, the negative part is the seam between layers will be observable.
It's not uncommon to suppose the 2cm substance is less costly since it's thinner than 3cm, but that's a myth. It's correct that the material price is reduced when comparing prices, however, the handling and production prices are exactly the same as 3cm substance since the practice is exactly the same regardless of depth.
Even though 3cm slabs weigh more, 2cm slabs cost the same when handling the material because it requires greater attention and care to prevent breakage.
Granite and marble countertops which are 3cm thick are powerful enough to support their own weight once installed cabinet foundations. Countertops which are 2cm thick are set up on a 3/8" plywood decking to maximize its potency and resistance to fat.
