Do you check behind the shower curtain ?

Even though it seems to be a large and expensive bathroom I am not at all comfortable with it. The bathroom seat feels disgustingly positioned or it's just that I am not used to such big bathrooms.

On the topic - Last 3 houses that I have lived in didn't have showers with curtains. I may look behind if I happen to be in a shower that has curtain and if I recently saw Psycho!
