Plastic books for wet places

I'll admit it: I read in the bath. I'd read in the shower, but I'm afraid that would be basically impossible. This is why I'm thinking that there should be books for showers. Or beaches. Or pools. Or rainforests. Or any muggy, wet place that poses a threat to the wellbeing of books. So, I present yet another entertaining idea: Plastic books for reading in wet places.

Instead of paper, the pages could be made out of thin sheets of plastic. That would save books from puffing up in humidity, as well as from the dangers of shower water or bath time book fumbles. If such a thing existed, I could fulfill my dream of having a bath tub in the middle of a library without endangering the books.
