  • a cleaning nozzle for a shower toilet, a seat for a shower toilet, a method for cleaning at least part of a shower device of a shower toilet by means of a cleaning nozzle of the shower toilet and a use of a cleaning nozzle of a shower toilet are to be specified , each of which at least helps to ensure that the shower toilet can be operated as pleasantly and hygienically as possible for a user.
  • the cleaning nozzle should be used to at least reduce the occurrence of splashes during the cleaning of the shower device of the shower toilet and preferably avoid it as far as possible.
  • a cleaning nozzle for a shower toilet contributes to this, with at least one waterway being formed between a water inlet and at least one water outlet of the cleaning nozzle, the waterway at least in sections at least one delay distance to at least partial laminarization forms at least one water jet that can be discharged from the cleaning nozzle.
  • the shower toilet is in particular a toilet with a bidet function.
  • the bidet function can be provided by a shower device in the shower toilet.
  • the shower equipment is usually used to discharge water in the tion of a user of the shower toilet provided and set up.
  • the shower device can comprise, for example, a water discharge element in and / or on which one or more nozzles can be formed in, for example, a shower section of the water discharge element.
