I love my prep sink!
Forgive me for bragging, but I love my prep sink. It is close to my refrigerator, range, and ovens, and has 66 inches of counter space and two drawer stacks beside it:
What makes it really special, though, is how much my GC was able to fit into a 30" sink base for me. I have a 16x21x10 zero radius sink, a compact disposal with airswitch, a Never MT, and two 8-gallon trash pullouts. The trash cans (Ikea) come with a dividing mechanism, so when warm weather returns I can separate my non-recyclable trash into compost stuff and dump stuff. We were able to do all this with just millimeters to spare, but we did it! The trash pullout set-up is a modification I learned from Ikeafans.
The only sacrifice I had to make was that we had to flip the orientation of the zero-radius sink in order to fit the plumbing in the space between the trash cans. But I have grown to like it this way (water hits the drain better), and wish I had turned around my main sink, too. My GC is my hero!
