My bathroom layout looks almost exactly like yours.
I have my 16x20 washer in the tub itself, with a tub-sized table over top. Thus my workflow is dev/stop/fix across the top of the table, rinse in an 18x22 tray fed from the washer overflow as Matt King suggest, wash aid in a similar tray that sits on top of the print washer, then into the washer. Sort of over-the-top, then under-the-bottom routing. The wash aid tray position will have to be reworked when I start printing 16x20, but 11x14 is fine with the above set up.
Might that type of scenario work for your needs?
