When we installed the bathroom about ten years ago (when I was still single) we got all fancy and installed sliding glass doors bathroom tub/shower.
Fast forward to three years ago I got married... we have stayed in a few hotels that have those shower curtains that bow out... wife is all "oh... lets get one of those!"
All the nicer homes I have been in have glass doors on the shower, therefore I prefer the glass doors.
Wifes argument is:
A) The glass gets spots on it that she has to clean with a squeegee (not a problem when I was a bachelor)
B) When we shower together we bump into each other (we are all wet and naked and rubbing up against each other... I don't see a problem here!

).
What do you have in your shower (besides midgets

)
