If you would like to add a sink to one of our base cabinets, we suggest that the sink dimensions are 20"W x 20"D x 10"H including the faucet. The width of the sink can be wider but should be at least 3" less than the width of the cabinet. Below are a few sink recommendations from different vendors that will work with our base cabinet that is 22.5"D. Menards Option Home Depot Option Walmart Option Lowes Option
