Abstract: A shower having a water saving system, which comprises a deviation device defining two trajectories of flow of the water coming from the conventional pipe, a tank for storing the water that exits when opening the handles controlling the discharge of water of the shower so that said deviation device deviates the “first” water towards said tank; and a venturi tube placed in fluid communication between said deviation device and the shower outlet, said venturi tube including a conduit extending inside said tank for connection with a hose to allow the water contained in said tank to re-enter into the conventional pipe to be discharged towards the shower outlet.
