Abstract: A toilet pot is comprised of four rigid or semi-rigid upright walls. The upright walls include two side walls opposing each other and a front wall and a rear wall opposing each other. Each side wall is formed of two panels hingedly connected together for folding inwardly. The upright walls together define a generally rectangular cavity. The front and rear walls are pivotably connected together with the opposing side walls. A seat member is hingedly connected to the upper edge of the rear wall for overlaying the generally rectangular cavity. The seat member is provided with side support walls which are hingedly connected thereto and capable of folding down along side the side walls such as to hold the side walls open when the toilet pot is in use. A removable fluid immersible lining bag is provided for insertion within the generally rectangular cavity defined by the upright walls. A second embodiment is disclosed having a removable seat member and alternative side wall support members.
