Base Cabinet
A base cabinet is a floor-standing cabinet that supports countertops and provides the primary storage in a kitchen. They typically stand 34.5 inches tall (36 inches with a countertop) and come in widths ranging from 9 to 48 inches. They house drawers, shelves, and pullout organizers, and anchor the kitchen layout by supporting sinks, cooktops, and appliances.
