I've been wrestling with buying or making a print washer for some time, now that I'm printing more fiber based prints. I decided to make a 11x14 print washer out of what I could find in the local hardware stores. It ended up costing about $70 and works quite nicely. I used a 10gal fish tank, nylon threaded rod and hardware, and plastic corrugated sheets, (like plastic cardboard). The set up is quite sturdy. I set something on top, like a Pyrex plate, to hold the prints down. I stick my flexible shower head down on one side and let it spill out the top. See attached pic.
