A multi-sided portable cabana that exhibits increased structural integrity and added dimensional qualities when compared to conventional cabanas, and that is also accessible to persons having physical disabilities. The cabana includes a generally flat, planar base and a plurality of interchangeable wall panels coupled to the base that extend generally perpendicularly upwardly from the base. A roof panel is affixed atop the plurality of wall panels. A door frame, including a door hingedly connected thereto, is positioned between two of the plurality of wall panels and includes a bottom edge generally co-planar with the flat base. Each of a plurality of wall connectors is positioned between adjacent wall panels in a lengthwise manner for coupling the adjacent wall panels. A wall rib is secured to an inner surface of at least two of the retainers and spaced apart therefrom to increase the structural integrity of the cabana, and to also provide persons with disabilities, such as those confined to wheelchairs, access to facilities housed within the cabana interior in compliance with regulations set forth by the Americans with Disabilities Act.
