A bath brush comprises a handle attached to a bristle block that contains bristles. A tank mounted inside the handle can be filled with liquid soap, liquid detergent, or other liquids to be used in washing the body. A pushbutton connected to a pump allows a user to select a measured amount of liquid while keeping the liquid from spilling, as it may when poured from a bottle. A check valve keeps liquid from running back into the tank and another check valve passes liquid from the pump to the bristle block but prevents anything from running back into the pump. While the bath brush is useful for anyone who is showering, bathing in a tub, or taking a sponge bath, it is especially useful for someone whose balance is compromised enough that he or she needs to hold on to something in the shower.
