I have a sectional shower. The problem is that the rubber? strip that divides each section has become dry rotted and corroded. Is is possible that a plumber or one who remodels bathrooms can replace these strips. I would try it myself but I don't know if the sections would collapse if the strips are removed. The shower is dry walled in. Also, I couldn't find the strips at any store. It would be ashame if the whole shower had to be ripped out. I would appreciate it if someone would enlighten me.
