Abstract: A portable sink is particularly adapted for use in a portable toilet and includes a cabinet in which a conventional five gallon bottle of water can be retained. The sink is designed to drain into the portable toilet, and a supply of deodorizing soap operates to both clean a user's hands and deodorize the entire portable toilet assembly. Suction cups are provided on rear and bottom surfaces of the sink to facilitate its attachment to the plastic housing of the portable toilet, and adjustable brackets mounted on magnetic supports allow the brackets to be positioned to fit virtually any manufactured shape of water bottle.
