I can’t answer your question, but do have a thing for you to consider. How hard is your water? Do you mind wiping down the chrome in your shower each time (or once a day)? The exterior plumbing pipes that you like will get spotted in hard water unless you wipe them down. My shower is the chrome palace, with grab bars, multiple valves, and hand-held chrome “jewelry.” We wipe it down after use and I have never had to clean it, otherwise. If you let it get yucky, though....
