There are two thicknesses of granite sold; 3cm (1 ¼") and 2cm (3/4"). Rock-It is your 3cm countertop leader in San Diego.

With thousands of installations under our belt you can trust our experience to make your dream kitchen a reality.

Although 3cm (1 ¼") thick granite is by far the dominant choice in the United States and Europe, you would not know it living in California which has been dominated by 2cm (3/4"). The granite industry is in transition and the east coast and mid states switched to 3cm granite years ago. It is finally starting to take hold in California.

The advantages of 3cm are many but the most obvious is that it is stronger and less susceptible to breaking and cracking and therefore the warranties provided are better.

The additional strength and rigidity of the thicker stone allows the elimination of plywood sub-decks and increases in unsupported over hangs.

When 2cm is fabricated a strip of stone is glued to the underside of the stone to hide a plywood sub-deck and give the appearance that the stone is thicker than it is. With 3cm the edge is routed out of the thick stone and there is no glued edge; no seam along the front edges of your countertops!

Does 3cm granite cost more?  Yes, but the fabrication cost is less. When using 2cm, the process of gluing a strip of granite to the bottom edge adds 4 to 5 steps to the fabrication process. So, what is saved in granite is spent in labor and shop time. When using 3cm more of your money is going into granite and less into labor and shop time.  The result is you are getting more granite, less worries and a better warranty for the same money; a better value.

80% of the granite countertops we see in kitchen and bath magazines today feature 3cm granite.
