Assuming twice a day showers?
once a day.
Foregoing a bit?
Eating the canned food or cooking the dry beans/rice?
Showers??? No, if it's a disaster, I'll moisten a towel. I live in a desert city, so no water means no water. We have creeks that flow from the mountains, but they're low most of the summer and there'd be too much competition for it. Yes, it's a city, but the point is not to have to be desperate by the time help arrives.
I live alone and keep two five gallon containers of fresh water in the back of a closet, so I figure 5 days at two gallons a day for drinking and cooking. I should get a third jug to make it a week, but I keep putting it off. I empty them periodically and treat them briefly with a dilute chlorine solution before rinsing and refilling them because the water might as well taste good. You can get stackable square or rectangular containers from the grocery or camping store and some come with built-in spigots.
I also keep chlorine tablets with my camping gear along with plastic bottles of propane for my Coleman stove. Lots of candles and batteries for my headlamp and flashlights. Not enough rice and beans or whatever socked away; I've always thought I should get one of those five gallon buckets that's supposed to last a family for weeks but they don't look particularly nutritious. Freeze dried food has come a long way, so I'm thinking of finding a cheap source and stocking up. Even MREs aren't as bad as they used to be.
