One of the best parts about using a farm sink or apron-front sink in the island is that they're often pulled forward a bit on the cabinet, and they don't require 3" of countertop in front of the sink hole. You gain usable counter space for your guests on the other side.
This says use a Farm apron sink when your sink is in the island because the sink is pulled forward and you have more room in back of the saint for your guests
