The invention it in a private portable toilet system for mounting on a vehicle for transport to the scene of an emergency where it is hydraulically lowered to the ground, and its component panels are out folded to an erected attitude, forming a cubical for containing a toilet platform that is hydraulically moved outwardly from its stowed attitude into which cubical, readying the toilet system for use, where, after use, the toilet platform is moved back to its stowed attitude, and the erection steps are reversed to collapse the toilet system by infolding the component panels to a flat vertical attitude and lifting the toilet system back to it's stowed position to the vehicle for travel.

A portable half bathroom is disclosed. The portable half bathroom may be in a compact condition or in an expanded condition. In the compact condition, the portable half bathroom looks like a regular cabinet. Collapsed and folded panels are attached to the cabinet. All side and back walls are racked on their relative sides of the cabinet when the portable half bathroom is not in use. In the expanded condition, the panels are unfolded and expanded to form an enclosure.

A portable toilet particularly suited to be a roll-out toilet positions a toilet with its holding tank at a rear wall, a sink at an opposed front wall, a urinal on one of the side walls and an access door through the opposing sidewall to provide access to the enclosure formed by the, front, rear and side walls. By connecting the drain from the sink to the urinal so that the water draining from the sink must pass through the urinal and then pass from the urinal to a toilet holding tank via a drain line connecting the urinal to a toilet holding tank the sink drain water is collected and will tend to wash and thereby clean the urinal.
