  • Sanitary fittings are used on sinks, washbasins, bathtubs and/or showers to provide a liquid, in particular water, as required.
  • sanitary fittings can have a fitting housing with an outlet and an outlet opening for the liquid.
  • the fitting housing of the sanitary fitting can be fastened to a support, for example a worktop or a sink or washbasin.
  • sanitary fittings can have a mixing valve, through which cold water and hot water can be mixed to form a mixed water with a desired mixed water temperature.
  • sanitary fittings are known through which hot water or boiling water can also be dispensed.
  • the sanitary fitting is used in particular to provide a first liquid and/or second liquid as required in sinks, washbasins, showers and/or bathtubs.
  • the first liquid can in particular be hot water, which can have a hot water temperature of 95° C. (Celsius) to 100° C., for example.
  • the sanitary fitting can have a hot water source, for example in the manner of a water heater or boiler, or can be connected to such a hot water source.
  • the second liquid can in particular be mixed water.
  • the sanitary fitting can in particular be supplied with cold water at a cold water temperature and hot water with a hot water temperature.
  • the cold water and hot water can be mixed by the sanitary fitting in particular, for example by means of a mixing valve or a (thermostatic) mixing cartridge, to form the mixed water at a desired mixed water temperature.
  • the cold water temperature is in particular a maximum of 25° C., preferably 1° C. to 25° C., particularly preferably 5° C. to 20° C. and/or the hot water temperature is in particular a maximum of 90° C., preferably 25° C. to 90° C., particularly preferably 55 °C to 65 °C.

  • the faucet housing has a (protruding or branching) outlet which is rigidly or movably connected to the faucet housing.
  • the outlet can be at least partially tubular.
  • the sanitary fitting also has a shower head with at least one first liquid channel for guiding the first liquid to at least one outlet opening of the shower head. Furthermore, the shower head can have at least one second liquid channel for guiding the second liquid to the at least one outlet opening. The first liquid and/or the second liquid can be released via the at least one outlet opening, in particular to an area surrounding the sanitary fitting. Furthermore, the at least one outlet opening can be designed in the manner of a mousseur and/or jet former.
  • the shower head can be pulled by a user of the sanitary fitting from a first operating position, in which the shower head is at least partially arranged in the spout, into a second operating position, for example in order to make the second liquid more flexible and/or in an area at a greater distance from the sanitary fitting than to be able to deliver in the first operating position of the shower.
