Just got mine done ( middle photo ), about 15 square feet of working space in the storage closet of our 820 square foot 2-bedroom apartment, vertically stacked trays, over 2,000 rolls of film in the fridge / freezer combo to the right. The 16x20 Eco-Wash connects to a diverter valve in our shower. Have been printing for two days and already sold three prints, 10 x 10's from Hassy.

My other darkroom goes over 100 MPH, gets close to 20MPG when not doing those speeds, has 235 watts of solar, a freezer, fridge and lets us stay out in the field for not days but weeks in the same location. I don't print in it yet but do soup film.
