Go ahead and do it. Just keep the wet and dry parts of the room separate and put in a locking doorknob so nobody walks in while you are making the ONE good print off that impossible negative (which Murphy's Law says you will never ever get right again). I am using the bathroom, at night, and it sucks to put it mildly. Every time I want to do something I have to schlep all the chemicals back in, mix the right dilutions, set the trays out, hang black curtains, drag the enlarger or floodlamp in, and simultaneously try to keep the critters from getting in and drinking from the trays (while not breaking my own neck). Not fun at all. I doubt you ever have to worry about film going away, and even if it did, there are other places to get chemicals.
