There are two primary thicknesses of countertops in the stone industry, 2cm and 3cm. Usually, 2cm are used in a bathroom, where strong demand is lower. The 3 cm are mostly used in kitchens. The 3cm thickness has more flexibility and is less expensive to install. The 2cm overlaid edge establishment requires pressed wood underneath the stone to raise the ledges over the cabinet opening. In high dampness atmospheres, the compressed wood may twist, making unsightly holes and costly fixes.
