A multi-purpose shelter adapted for use as a toilet, shower or changing enclosure of such size as to accommodate a person, has in a preferred embodiment a floor with ventilation and drainage slots surrounded by a cylindrical wall of bellows like configuration. The bellows side wall is integral with the floor and top ring, is freestanding in an extended position and collapsible into a low profile form for quick and easy transportation, storage or shipment. The fabrication elements used for the manufacture of this invention may be of plastic, rubber or other pliable matter. While polyethylene is the preferred material through a blow mold or rotational mold process, a wide variety of other materials capable of being formed into films or sheets can be satisfactorily employed. The primary requirement is that the bellows like wall provide the flexibility and durability necessary to withstand wind, sun, salt water and other elements without damage, warpage, erosion or distortion.
