A shower-mounted back-scrubber device is installed on the wall of a shower stall at a height approximating the height of the user's back. The device has a pair of scrub brushes that rotate and reciprocate vertically. The user stands comfortably with his or her back abutting the device. The brushes traverse and clean the entire surface of the user's back without awkward manual manipulation or translation relative to the device. The brushes are motor-driven by a drive shaft connecting the motor to a transmission. The transmission and drive shaft have a telescoping connection that permits positioning a housing of the device relative to the motor. A controller regulates rotational and reciprocal speed of the brushes.
