The thermostatic tap comprises a housing 1 with three independent chambers (5, 6, 7) that are connected to their respective outlets (5a, 6a, 7a) of liquid fluid. The tap is able to direct the flow of liquid fluid towards one of the three possible outlets of the thermostatic tap: shower mode, cascade shower, or jet mode. It also includes a protective nozzle (23) used to protect at least one of the outlets of liquid fluid in order to prevent a rim that forms part of the housing of the thermostatic tap from deteriorating. The thermostatic tap that is the object of the invention is also able to reduce the noise made by the flow of liquid fluid as it travels inside the housing of the thermostatic tap towards its outlets.
