About showers

Hey guys I've been on haemodialysis for a few months now Lately I've been having trouble taking a shower and keeping my catheter dry. What I usually do is cover it in a plastic bag and over the plastic bag I put some tegaderm patches, it was very useful at first. But I think ever since I developed dermatitis from the regular daily patches well none of them usually stick properly to my skin anymore. So it will usually peel from one side, letting water get in, so I have to quickly get out and redo it

Anyway, I'd really appreciate if you guys could give me tips for how to shower with the catheter so I can keep it dry. Thanks so much
