Five piece vanity sink set. Dimensions listed are for the center double sink compartment vanity that's really well made with 3/4" finish grade maple plywood. There a 15 5/8" wide x 13 7/8" deep bank of three drawers that could be attached to each side. You'd probably use one of the 2 1/2" wide spacers between the sink base and the drawer bank if you're going to use them. All drawer glides are full extension and soft close.
