The invention relates to the technical field of bathing equipment used in daily life, and provides a water-saving shower set which comprises a spray nozzle, a flow direction regulation valve, an inner casing pipe, an outer casing pipe and a water storage tank, wherein the outer casing pipe sleeves the outer part of the inner casing pipe; one end of the outer casing pipe is arranged on the spray nozzle, and the other end is communicated with the water storage tank; the flow direction regulation valve sleeves the inner casing pipe and can move relative to the inner casing pipe; the inner casing pipe, the flow direction regulation valve, the outer casing pipe and the water storage tank can form a first channel; when the pressure in the outer casing pipe reaches a predetermined value, the flow direction regulation valve is pushed to move toward the spray nozzle, so that the inner casing pipe, the flow direction regulation valve and the spray nozzle form a second channel. Residual room-temperature water in a pipeline is stored in the water storage tank to avoid the waste of water resources; after a shower switch is turned on, water flowing out from the spray nozzle is warm water and can be used directly without testing the water temperature repeatedly, so as to be more convenient to use.
