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.

1. A portable shower, comprising: a collapsible enclosure having a flexible liner and a collapsible skeleton of elastic material secured to the liner, the skeleton being secured to the liner so that, when permitted to elongate longitudinally, the skeleton supports the enclosure in a three-dimensional extended configuration with the liner surrounding an inner space large enough for a person to stand in with the enclosure having a height of at least 4 feet, and wherein the skeleton is configured to be compressed longitudinally to collapse the enclosure down to a longitudinally flat configuration for transport, the skeleton of elastic material being formed by a series of connected struts surrounding the inner space, each strut following a helical path when the skeleton elongates, the struts being discontinuous around a circumference of the skeleton so as to define a longitudinal gap on one side of the skeleton extending between an upper circular ring and a lower circular ring, and the liner has a longitudinal opening aligned with the longitudinal gap large enough for ingress and egress of the person to and from the inner space; anda flexible water hose connected to a sprayer and attached to the collapsible enclosure, the hose being incorporated into the enclosure so that it collapses and expands with the enclosure. 2. The portable shower of claim 1, wherein a total weight of the portable shower is between 4-7 lbs, and further including a flat circular carrying bag into which the collapsible enclosure can be fitted in its longitudinally flat configuration. 3. The portable shower of claim 1, wherein the hose is held within pockets sewn into the liner. 4. The portable shower of claim 1, wherein the skeleton and the water hose are both secured around the liner from a first, lower end to a second, upper end of the liner. 5. The portable shower of claim 1, wherein the liner opening includes a closure selected from the group consisting of a zipper, flaps with mating hook and loop fasteners, buttons, and ties. 6. The portable shower of claim 1, wherein the series of struts are connected by junctions, the junctions being detachable from the struts. 7. The portable shower of claim 1, further including a base plate with a floor raised above a surface upon which the portable shower stands and having a plurality of perforated drainage holes, the collapsible enclosure extending upward from the base plate, and wherein the base plate is molded of a polymer and has a peripheral rim around the floor with an upper lip rising above the floor and a lower lip, the lower lip extending down from the floor so as to raise the floor up above the surface upon which the portable shower stands, the lower lip having a plurality of gutter holes distributed around a lower edge to prevent the water that passes down through the plurality of drainage holes from becoming trapped below the floor. 8. A portable shower, comprising: a collapsible enclosure having a flexible liner and a skeleton of elastic material secured to the liner, the skeleton being secured around the liner so that, when permitted to elongate longitudinally, the skeleton supports the enclosure in a three-dimensional extended configuration with the liner surrounding an inner space large enough for a person to stand in, and wherein the skeleton is configured to be compressed longitudinally to collapse the enclosure down to a longitudinally flat configuration for transport, the skeleton of elastic material being formed by a series of struts surrounding the inner space wherein adjacent struts form a V-shaped angle with respect to each other when in an extended configuration and are each connected by a junction, the junctions defining a discontinuity around a circumference of the skeleton so as to form a longitudinal gap on one side of the skeleton extending between an upper circular ring and a lower circular ring, and the liner has a longitudinal opening aligned with the longitudinal gap large enough for ingress and egress of the person to and from the inner space; anda flexible water hose connected to a sprayer and attached to the collapsible enclosure, the hose being incorporated into the enclosure so that it collapses and expands with the enclosure, wherein the hose is held within pockets sewn into the liner, and the hose extends partly in alignment with individual struts and partly along vertical shortcuts between struts to avoid sharp bends. 9. The portable shower of claim 8, wherein a total weight of the portable shower is between 4-7 lbs, and further including a flat circular carrying bag into which the collapsible enclosure can be fitted in its longitudinally flat configuration. 10. The portable shower of claim 8, wherein the liner opening includes a closure selected from the group consisting of a zipper, flaps with mating hook and loop fasteners, buttons, and ties. 11. The portable shower of claim 8, wherein the junctions are V-shaped and spring loaded to assist in expanding the enclosure to its extended configuration. 12. The portable shower of claim 8, wherein the junctions are V-shaped and have locks to enable the junctions to be locked into several angular orientations including an expanded V-shape. 13. A portable shower, comprising: a collapsible enclosure having a flexible liner and a skeleton of elastic material secured to the liner, the skeleton being secured around the liner so that, when permitted to elongate longitudinally, the skeleton supports the enclosure in a three-dimensional extended configuration with the liner surrounding an inner space large enough for a person to stand in, and wherein the skeleton is configured to be compressed longitudinally to collapse the enclosure down to a longitudinally flat configuration for transport, the skeleton of elastic material being formed by a series of struts each extending between 270-315° around the inner space and having junctions defining a discontinuity around a circumference of the skeleton so as to form a longitudinal gap on one side of the skeleton extending between an upper circular ring and a lower circular ring, each junction being convertible between the longitudinally flat configuration of the enclosure and the three-dimensional extended configuration of the enclosure wherein adjacent struts form a V-shaped angle with respect to each other, and the liner has a longitudinal opening aligned with the longitudinal gap large enough for ingress and egress of the person to and from the inner space; anda flexible water hose connected to a sprayer and attached to the collapsible enclosure, the hose being incorporated into the enclosure so that it collapses and expands with the enclosure. 14.
