Bars, bars and more bars. My house looks like a display for bathtub bars, toilet bars and Shower bars. I have put in about 45 feet of them, and they are a great comfort to me. Don't think of it as closing the door after the horse has left, because you will use them for a long time.
I put some in for my father(83) as well last year. When he fell (I knew it was a matter of time), while he was unable to keep from falling with the bar, he was able to control his landing (on the softest part). I am confident that saved his hip right there....
