HI All. I received a reasonable modification request for a unit and one of the requests involves installing grab bars in the stand up shower, which is tiled. (the others are for a ramp and a chair lift to be installed) We have never done that before (we are willing to do it of course), but is there some type of liability we should be worried about with the grab bar? My boss is worried about the thought of them coming loose. (WE are a small family owned company, no corporate office/no HR) We are just wanting to do things the correct way. I am going to send written permission for this but want to cover all my bases. Thanks.
