Disclosed is an adjustable jet shower device, comprising a jet spray valve, wherein the jet spray valve is provided with a valve body (1), a spray nozzle (3), a spray needle (4) and a water outlet. The spray needle (4) is arranged in the spray nozzle (3); a cold water inflow space and a cold water jet outlet are formed between the spray nozzle (3) and the spray needle (4); a hot water inflow space is formed between the spray nozzle (3) and the valve body (1). Adjusting the spray nozzle (3) to make it move in the axial direction of the jet spray valve can simultaneously realize an adjustment to the cold water inflow space, the hot water inflow space and the jet cold water outlet, thereby realizing a better spray effect by means of a simple manner of operation.
