Let me run some ideas by you and see what you think. Space and the ability to take the darkroom down quickly is important. The challenge is to print 35mm and 6x6 (love to do 4x5 ) with a temporary set up and break down darkroom in a small bathroom by the spare bedroom in a condo. We occasionally have guests and such so I need to be able to take everything down and store it. I will add photos and dimensions of the bathroom in my next post. Basically there is a commode, small vanity with a sink and a shower with some hearty glass sliding doors. My first problem is I do not presently own an enlarger, but just about all other materials I have or can come up with. That may be a blessing because hunting for something to fit the need might be better than trying to figure out how the last enlarger I owned could fit in the space. I am considering building a base for said unpurchased enlarger that would span the lip of the sink of the vanity and cover the sink. Like to have the sink, but there is no counter space available. Leaving the commode for a place for paper safe, a seat and personal needs. Placing the trays in the bottom of the bathtub and living with sliding the glass doors back and forth to go from the open side on the left for dev and stop, the right side open for fix and wash. A simple hose down from the shower head into the wash tray may not be the best for archival washing or my back, but OK. One other option is a rack of some kind to place the 4 trays vertically above each other. the Dev on down to the wash. That way one does not need to bend over the tub and slide the glass doors back and forth. I think I like this option better, because moving the glass doors and leaning in from atop of the commode from the left side of the tub is not fun and the wife will not like me taking the glass doors off all the time. (I think) Print drying might be accomplished on a small homemade rack or by blotter book. So please add your thought here on what might be the best way to set up and tear down a simple darkroom in a spare bathroom.
