I have been running into these same issues - where I work, restaurants, hotels... EVERYWHERE.

I looked into it and the ADA regulation specifies that the bars MUST be 37 inches from the ground! I have a genetic disease that caused me to have a spinal fusion. In addition to that, I have muscle weakness so doing pull-ups with a 37 inch grab bar is not a possibility for me. It is nice to know I'm not alone. I wonder who we could talk with regarding this ADA regulation??
