Abstract: A flow way diverter device includes a water flow divider and a supporting frame. The water flow has a water inlet, and first and second outlets for operatively coupling with a stationary showerhead and a handheld showerhead respectively, and a switch selectively switching water flowing from the water inlet to one of the first and second outlets. The supporting frame is rotatably coupling with the water flow divider for supporting the handheld showerhead to selectively adjust an inclined position of the handheld showerhead with respect to the water flow divider. Therefore, the stationary showerhead and the handheld showerhead are connected to the water source and are supported on the wall without pre-drilling a mounting hole on the wall.
