A shower device includes an elongated hollow waterway, a spray head configured to emit water, and a valve. The elongated hollow waterway extends in a longitudinal direction and has a first end configured to receive water, a second end, and an internal fluid passage extending from the first end to the second end. The second end has a port extending in a radial direction from the internal fluid passage through the waterway. The valve is configured to control a water flow rate from the internal fluid passage of the waterway to the spray head. The valve includes a valve body that surrounds the port and a control member operatively coupled to the valve body and surrounding at least a portion of the valve body. Rotation of the control member and valve body relative to the waterway provides a variable adjustment of the water flow rate to the spray head.
