Our Island Countertops come in both Stainless Steel and Chopper finishes and are the perfect solution for island prep surfaces or sterile work centers. Each island countertop is 1-1/2" thick with finished square edges. Cabinet grade plywood substrate is included for installing your countertop. The stainless steel countertop is 16 gauge and has a 304 brushed finish. The copper alloy in our copper countertops has 99.7% copper material. The available finishes on our Copper Countertops include brushed, matte, or mill, and the counter is uncoated to allow for the full health benefit of the copper material. The Copper Kitchen Countertop will require regular cleaning to prevent patina over time. Our Island Countertops are designed in a standard size or can be ordered in custom sizes to match your kitchen requirements. There will be an additional charge for cutouts and larger sizes.
