When you entered the toilet, the light switches on. It seems there's a motion sensor involved here. On the downside, you will soon discover that the light switches off again after a couple of minutes without any movement.
Mounted on the back wall are some speakers. Next to the toilet paper holder is a small box with a volume control knob and a button labelled 'skip'.
The door is entirely covered in cut out funnies and comic strips. First time anyone visits our toilet it takes them some time to work through all of it.
