I always read in the bath, now, being able to read the bath itself, that's really something!
If you fall down in the shower even once you know you'll do whatever it takes to make sure it never happens again.
I'm all about combining different uses in one room but I've never seen a combination library/bathroom. I'm a big bathtub reader myself. I've never been one for reading on the toilet but to each his own.
When I'm in there it's like going to the aquarium to see the beluga whales in the underwater tanks.
