Sorry I don't have good news for you!
My personal experience with a camp shower was not very good. The water did not get too warm - even though we left it in the sun as the directions indicated. Also, it was tough to get the water to flow from the little spout thing.
That said, I know some people who have really liked them.
I'd suggest giving it a try at home before you pack it along with you!
Good luck.
