Jim, you said no plumbing about a bathroom. It will be a pain to track sawdust into the house to use a toilet, but can be done. The more troublesome issue will be where to clean brushes and the like - y'know, utility sink stuff. The kitchen sink is not a great solution. How about a not-to-code sink in or just outside the shop? It would discharge on to a gravel pad. The water source would be a tank you fill occasionally with a garden hose.
