I have a right angle shaped sink that I process a lot of 20x24 prints in and what I did was to stack the trays with a wooden homemade shelf system. I have stacked, dev, stop, fix 1, fix 2, and permawash at the bottom. This leaves me room for a bleach tray (for sepia) a wash tray, a toning tray as well as a archival print washer. I am able to do the entire process at one time.

Some people don't like the stacking system but it is easy to get used to and the space savings are great.

Just and idea,
