Cramped, but at least already set up. In a small apartment with a 5X7 foot bathroom I have to set up with a board on the sink for the enlarger, board across the tub for the trays, paper sits on the toilet seat, and then unscrew the four white light bulbs on the top of the medicine cabinet. (I have to leave the light switch on, it also powers the electric plug in the wall.)
Then, just as I am opening a box of paper the missus says; "Honey, I have to go to the bathroom"
