A bathing aid device comprises adjustments to accommodate varying user body shapes and sizes and may be used in conjunction with most, if not all, bathtubs. The bathing aid device, when used as described, allows for more complete and safer bathing for those incapable of bathing themselves. The device includes a kneeling platform for being placed beside a bathtub, a column assembly, which extends from the kneeling platform to a position above and preferably slightly forward relative to the bathtub wall, and which holds a preferably pivotal clavicle-region support. The user leans on the clavicle-region support, and, because of its location relative to the bathtub and the user's upper chest, and because of its small dimensions, the support is especially comfortable and effective. The user need not rest on the device with her/his elbows, arms, shoulders, or breasts, and, instead, the user is well supported high up on her body and can easily reach around the device to assist an infant, bather, or pet inside the bathtub. The preferred column assembly is quickly and easily removable, without loosening any fasteners, in order to move the assembly out of the way before the user rises or lifts a child out over the bathtub wall.
