Abstract: A collapsible and portable cleaning unit. The unit is preferably designed to provide a private shower experience that is comparable to a shower experience for a permanent shower installed at a location, such as a bathroom in a dwelling. This inventive shower unit is designed to be fully portable in a self contained collapsed mode that is substantially contained within the overall footprint of the unit. The unit includes a substantial self supporting base structure and a cap that secures to the base structure to protect the internal components and seals for storage. This unit includes a supportive base that has a pan for directing and containing water from the shower. The unit is designed to provide height clearance that is substantially comparable to showers that are in permanent facilities and/or dwellings.
