The nozzle of a bidet toilet seat will remain inside the seat by default. They pop out only when you turn it on. The design of the bidet ensures that no dirty water falls on the nozzle. Either the bidet will have a remote controller or a control panel on the right side of the seat. Using this control, you can adjust the spray. You can point it towards the rear or front, adjust the strength of the spray and, in some models, adjust the temperature as well. Some bidets also have the option to dry. When you turn it on a stream of hot air will dry your area. If your bidet doesn’t have that feature, you can simply use a tissue paper.
