A motor activated bathtub drain closure is associated with the bathtub having a bottom with a drain opening therein. A vertically movable drain stopper is mounted over the drain opening. A drain pipe is connected to the drain opening and is conventionally positioned below the drain opening. A motor having a movable element is located outside the drain pipe and is preferably mounted on the drain pipe. Linkage is secured to the movable element and extends from the movable element into the drain pipe and terminates at an inner end underneath the drain opening. The linkage is so configured that when the movable element is moved by the motor from a first position to a second position, the inner end of the linkage will engage the stopper and raise it with respect to the drain opening to permit fluid in the bathtub to flow by gravity.
