Abstract: A lightweight portable shower foldable into a backpack for campers or the like. A pliable water storage bag lies on a floor unit that also supports a vertical, sectioned, standpipe having a valved showerhead at the top. An annular curtain rod is held in a horizontal position by a hooking device at the top of the standpipe and supports a tubular shower curtain that is elastically connected to a rigid footpad atop the storage bag. In use, the weight of the user standing on the footpad provides water pressure to force water through the standpipe and showerhead. The elastic coupling to the footpad assures that the curtain will remain taut as water is forced from the storage bag.
