Abstract: A portable collapsible toilet enclosure includes a base portion and a lid portion which is vertically moveable relative to the base. The base and lid are connected by one or more telescoping members and/or a collapsible door structure, which telescoping members and/or collapsible door structure extend to raise the lid relative to the base and are lockable in the extended position to provide structural support for the enclosure. The telescoping members and/or collapsible door structure are retractable to lower the lid relative to the base, and the lid may be secured to the base thereby creating a portable unit.
