One drawback of the corner sink – it’s hard to reach into the corners in the back of the sink to clean them. You have to lean very far back (not to mention trying to cover the counters for Pesach).
I have 2 corner sinks, they take up the least space that way. One has a backsplash behind it, that one is hard to clean, the other is facing the eating area, so there is no wall behind it. I just walk around the peninsula to clean it.
