Sink Base Cabinets
Sink bases are the wet zone of the island. Full-height doors (FSD / FDD) give a deep basin or ice chest a clean face; combo drawer-over-door (CSD / CDD) puts cutlery up top and the sink bowl behind a false front. Pair with a Sunstone drop-in or undermount sink. ADA44BC is the 44" accessible combo. Every cabinet has a floor plumbing cut-out so the shelf stack can stay in while the plumber works.

Leave the shelves in
The floor plumbing cut-out is sized so the shelf stack can stay in the cabinet while the plumber works.
False front or drawer
CDD cabinets ship with a reversible top drawer / false front so the sink bowl can sit behind a clean face.
Swing matters at 18"
FSDL / CSDL open left; FSDR / CSDR open right. Order the swing that clears the neighboring cabinet or wall.
