A portable shower includes an enclosure that converts between a two-dimensional collapsed configuration and a three-dimensional upright configuration defining a space therein for a person. The enclosure is self-extending and free-standing in the upright configuration, and desirably has a height of at least 4 feet. The enclosure includes a liner, preferably tubular in shape when extended, and an integrally attached collapsible skeleton such as an elastic coil, preferably helical. The elastic coil has a sufficient relaxed size and spring constant to self-expand the liner when constraints are released. A water reservoir connects to a shower sprayer through a hose, and may be integrated in the wall of the enclosure. For instance, a helical sleeve around the liner may constrain both the elastic coil and the hose. A foot pump may be provided along the hose and within the enclosure for easy propulsion of water from the reservoir to the sprayer. |
