I love mine, I'm actually thinking about installing black curtains and other light-blocking material for the kitchen too, so that I can use the kitchen as an extension.

If I'll ever have to live in a single room with minimal space for any reason, however small it would be, I would convert it to a permanent darkroom. It's possible to work around the water or temperature problems if one is willing to. Convenience in a darkroom is like coverage for LF lenses: it's good to have plenty of it, but in reality just barely enough is good enough for a good number of tasks.
