You can get ones with a warm air drier built in as well, the one we saw had grey bottom, pink bottom, temperature, pressure and warm air drier controls. What a fun way to spend a few minutes.
We provide them for disabled people who are no longer able to manage to attend to their own hygiene in that area. The water spray comes out fast enough to hit the ceiling so if you want to demonstrate one to people, you have to remember to put a bit of plastic over the pan before you press the button.
Forgetting is a mistake you only make once!
