Something i do right outside the shower stall i have a stool of type that i rest my phone on and easily reachable in the event i need to call someone or message them to help in whatever way needed. once i fell and was able to slide the stool close enough to reach my phone and call for help. In front of the shower on the floor two things, a rug with a traction mat under it so it wont slide and a extra towel large kind if needed for warmth or whatever you can use it for. Big enough that you can be lifted off the floor if the case should arise. Last for now a first aid kit that is up to date and made for people that have falls, a few of the strips that can pull skin back together to stop a cut or torn skin back together to slow bleeding and compress to apply direct pressure till the wound stops bleeding or help arrives. That's it for now
