Whether you own a quartz or granite countertop the thicker ones are considered the classics. 3cm material can go directly on top of the cabinets without the need for plywood support. While inch thick granite countertops are typically seen in bathrooms you can install them in the kitchen as well.

Countertops that are 2cm thick usually are installed on a 3 8 plywood decking to increase its strength and resistance to weight. The table below lists the standard weights of the two slab options.

Three centimeters is the preferred thickness for both quartz and granite countertops for most countertop fabricators designers and architects. Granite and marble countertops that are 3cm thick are strong enough to support their own weight when installed on cabinet bases. So let s go over standard granite countertop thickness.
