Your current set up is almost perfect, actually. You would only need one of those bins to drain, right? Why not drill a 1" hole in bin 3, find a rubber fitting you can seal and tighten, and then run a length of 1/2" vinyl tubing out of it into your sink drain? Run another tube from the faucet into the bin and you've got a wash sink. When you're done, stack 'em back up in the corner. No need for the developer and stop bins to drain.

I can cut a whole in one of the plastic tubs, place it over the current household bathroom sink, and put the wash tray in it.
ETA: I think the light bulb just kicked on... A wall mounted piece of 3/4" ply that is hinged to fold up for processing trays and extra counter space, and then a hole cut in one of those bins for my print washer and placed over the sink for draining.
I can't wait to get this started!!
