Hi Old Bruce,
Showering was a huge stress for me as well. I wore my brace in the shower with a garbage bag around my leg. I was nervous but able to manage, I had a lot of help from my husband and daughter as well. So if you have someone to help you navigate getting in and out, just keep the brace on and keep it dry. A chair is also a good idea if you want to go that route.
Good luck with it!
