I used to have to share the bathroom with the wife (probably was a good thing she wanted to keep herself tidy). I used to store enlarger in a cupboard and it took about 15mins to setup but I couldn't print during daylight as the bathroom had a skylight which was hard to stop the light coming through. Since this was pre-scanner, I used to like to print a contact sheet of developed film sooner than the next 'full' printing session. I decided I could do a proof sheet without the enlarger to save some time, just setup the trays and used the room light as the light source. I think I ended up changing the globe in the light fitting for a lower wattage one so I could get longer times and could manage a fairly accurate time by counting to myself. Using a desk lamp might be easier.
