A diaper retaining enclosure within which a soiled diaper may be retained while being rinsed. includes a generally planar base having parallel edges to which a pair of suitable hinges are secured. A pair of doors comprising generally planar flaps are secured to the hinges and are thus pivotable between an open position exposing the base and a closed “tented” position. The tented position is achieved by having the edges of the doors meet some distance away from the base in the closed position and thereby form a channel extending downwardly above the base and behind the doors. A clip is secured to the upper edge of the base and is configured to be spring-biased to a closed position. The resulting channel formed by the doors in the tented position is open at its top and bottom.
