A portable lavatory, which is easily loaded into a freight box of a truck and is maintained in a stable loaded state in the freight box during transportation, is disclosed. In the portable lavatory ( 10 ), the capacities of both a fresh water tank ( 20 ) and a foul water tank ( 30 ) of a tank unit ( 12 ) are altered in inverse proportion to each other. The tank unit ( 12 ), integrated with a lower end of a lavatory facility unit ( 11 ), has a width and length shorter than those of the lavatory facility unit, thus being stepped inward from the lower end of the lavatory facility unit. The fresh water tank ( 20 ) and the foul water tank ( 30 ) are assembled with each other at flanged open ends thereof into a single structure, with a variable tank ( 40 ) provided in a junction part between the two tanks.
