Showers can be difficult with COPD. Here are some things to try that should help a bit. If you use 02, take it in the shower with you; draping the hose over the shower curtain usually works or with glass door showers, just pull the hose in and shut the door. Most won't close hard enough to shut off the 02; mine works just fine that way. Get a chair or figure out some way to sit down. Use a handheld shower head. Make sure you have soap, shampoo and anything elseyou need easily accessible. There are lots of shelf arrangements that work really well. Have a chair ready to sit in and a big towel or robe to wrap up in for when you get out. That way you can dry off without a lot of effort. These things work for me when I need to use them.
I fine it easier to take a bath. I take my carry oxygen in the bathroom and can wear it while I bath. I have the hand shower head dangle down to use when I wash my hair. I keep all I need in a easy reach area.
I also leave the bathroom door open so the humidity can get out
