Hawk Pilot, in our camp we have settled on the use of Stearns Sun Shower bags. The first bag was the 5 gallon size, but there was always someone hogging the water and one or two guys ended up with no water at shower time. The heck with that, so I bought the 2.5 gallon size for myself and actually can get two showers from that size.
I like the flexibility for heating water on a rock in the sun, truck hood or heat water. The bag has an easy on/off value to conserve water.
We use a small plastic tarp for a shower stall and attach it or wrap it around anything that is handy. For three or four years we used a small piece of canvas to stand on to avoid dirty feet, however a bud nailed some small cedar boards together and we stand on that now. Just another little bit of convenience at the base camp.
I use the same bag at my hunting and fishing camp in Wisconsin and when using my pop-up camper.
