Sounding like a gentle rain, "Rain" fountains are the easiest of the designs to maintain. They are also excellent humidifiers, as they produce a very fine mist. Depending on your current conditions, a Rain fountain may add an additional one to two gallons of humidity to your environment, ideal for Southwestern climates, dry winter conditions anywhere, garden rooms, and even wine cellars. Fabricated in copper, "Rain" fountains are available in four basic designs, but can be customized to your specifications. A copper base tray is available if any possible mist on your floor is a concern.
