I no longer close my eyes when shampooing, but also I toe up to the edge of the tub, and press the tips of my toes into the side wall, just for extra stablity while I scrub my head. All the wobbling back and forth can make a girl dizzy.
btw, I am on my 12th towel rack that hangs just outside the shower. I told the DH last time it came down to bolt it the the STUD, not just sink it into the dry wall. So far this one has lasted.
nothing worse than being naked, and wet, and doing a face plant on the side of the toilet.
