Okay, my darkroom class has just ended, (very sad to say) and I am thinking about making my own. My teacher gave me all of the prices for everything and what and where to buy. The question is...how. I was thinking of making it in my downstairs bathroom, which nobody uses and has no window. It has a sink, of course. Is it possible to construct a darkroom in my bathroom? Do I need a permit of some kind for using these chemicals and such, fire hazards, etc. etc.
