A sliding partition enclosure system for a modified portable commode cabana with a private urinal cabana, providing simultaneous dual use. A commode cabana's internal compartment includes a commode and waste containment chamber disposed below. An external shell including: a roof, three wall panels, a front panel with latching door and a floor panel with external parallel tracks, a urinal affixed upon the external shell, a drainage system connecting the externally mounted urinal to the enclosed waste containment chamber. A sliding partition unit when extended, provides the private urinal cabana enclosure, including: two horizontally side panels on external parallel tracks of the commode cabana, a front panel with latching door, a roof, and a floor panel hinged to the commode cabana's floor that folds down, stabilizing the sliding partition enclosure when in use. The floor folds up and the partition slides closed when not in use for portability.
