Below you will find coin boxes that we recommend for paid time water at showers, campsites, washing places or gyms. For use with showers, other accessories such as transformers and solenoid valves are often required. The coin mechanism switches a solenoid valve, which is installed in the water pipe. Depending on the local conditions, low voltage may be required. Please clarify this with your installer. Often, the use of coin-operated equipment made of stainless steel makes sense. Further information on the use of coin devices on showers can be found below on the page.
