I will add that while doing 8 rolls of c-41 tonight it made me greatly appreciate having a sink right there. A large sink is great to contain the constant flow and splashing of a water bath. One could foreseeably do this in the kitchen however. It's just easier and more convenient in the darkroom. If you're like me and do a lot of printing it's damn useful having the sink right there. Also being able to contain the print washer rather than breaking it out on the kithen counter everytime is a big plus.

If one can wing it they should figure out a way to get water in the DR. As someone who has done it without water for a while I wouldn't go back.
