I got in the habit of "field showers" also known as "whores baths" in the military. Back then we used an empty ammo can and used it to wet our wash cloths with and sponge off. If you were lucky you could heat up the ammo can in a fire, but that was rare. The only times we got showers were when it rained. Heck, I was at one place where the only shower you got was being hit by a fire hose every 10 days.

When backpacking I carry a folding bucket that I use as my camp sink and wash basin. Not to mention hauling water for the gravity filter. Never really considered a camp shower as I never saw more than 1 purpose for it and I didn't think they looked very durable. Either I use bio-degradable wet wipes, dip in the stream or field shower.
