The Moen trim in my shower is two-toned and corroded. I don't need a new valve, just a new trim kit for the shower handle. I've replaced the shower heads with others already, but I'm having zero luck finding a Moen trim kit in polished nickel. It seems like brushed nickel and chrome are the only options. I plan to eventually outfit the entire bathroom in polished nickel, so I'd really rather not have a different finish on the shower levers. Anyone have any sources I'm just not seeing?

Thanks!
