If sick, put a stool in the shower stall

If you are sick or can't stand for a longer period of time, a stool is a great help in the shower stall. The ones you can buy in a medical equipment store are way too expensive. So I just picked up a cheaper stool (made out of plastic) which was a stool for the balcony but works great in the shower.
I put it in the shower stall, and before I take a shower I just wash it off with warm water and then sit down. Once in a while I clean the stool with a bathroom cleaner.
