Quite often new immigrants are confused about the mini-shower found in many Finnish restrooms, both public and private. My fellow immigrants, if you haven't already learned what this device is, let me give you a hint. It is not a drinking fountain.
The alapesusuihku is a handy innovation that you will find in practically every Finnish WC. Dish-sprayer meets bidet, giving one a chance to freshen up "down there" both safely and conveniently.
The butt sprayer usually uses the same plumbing as the bathroom sink. Turn on the water, adjust the temperature, grab the sprayer and engage in a bit of personal hygiene! You don't want to be known as the foreigner with the stinky posterior!

This classic advertisement will give you an idea of how to use the alapesusuihku if my instructions didn't come through clear enough.
What an effective bit of advertising. It's no wonder that this handy innovation caught on so effectively here in Finland!
