I need to have my shower door replaced.  I need the handle changed on my shower faucet.  I have arthritis in my hands and have a terrible time turning the large plastic ball that is currently there.  I have a lever handle that I hope will fit (brand new in the box).  I also need a different kind of grab bars in inside and outside of the shower.  I have balance issues and do feel safe with what I currently have.  My shower is tiled and I hope that the holes can be patched so they will not show.  I also have a shower caddy that needs to be screwed to the back shower wall.
