A sink grid is a easy way to preserve your stainless steel sink or any other sink you may be installing. It does protect the bottom of your sink and usually has rubber or coated feet to eliminate the possibility of rubbing a large pot or pan and gouging or scratching the sink. These are not available on all sinks, but most reputable manufacturers offer this accessory on their popular sink configurations. Check with your sink guy or retail supplier if a sink grid and additional accessories are available ( e.g. – colanders, cutting boards, special drains).
