A seal for a bathtub door is releasably retained in a groove by a mechanical interlock. The seal has a first, relaxed condition in which it is unable to pass through the opening of the groove, and a second, tensioned condition in which it is able to pass through the opening of the groove. The door is held closed in a watertight manner by a latch having a contacting surface beveled in two directions. The latch has a curved, tapering shape that makes it well suited to be grasped and/or manipulated by the hands of handicapped or arthritic persons. The groove is formed during the molding of the door by a groove-forming element releasably attached to the mold. When the door is removed from the mold, the groove-forming element separates from the mold and remains in the groove, but is removable from the groove by applying longitudinal tension.
