A shower caddy for attachment to an associated outer enclosure panel or door of an associated shower or tub enclosure includes a body and an attachment mechanism mounted on an end portion of the body. The attachment mechanism has at least one movable mounting arm. The attachment mechanism is configured such that downward movement of the body relative to the attachment mechanism by force of gravity moves the at least one mounting arm from a rest position toward an engagement position where the at least one mounting arm is engageable with the associated outer enclosure panel or door.
