Not sure what you mean by “Shower Door frame has had it…” They seldom wear out, but do get pretty grungy over time…what exactly is wrong with it?
Removing the old and upgrading the whole thing with frameless, perhaps 1/4″ or thicker clear glass can get pretty expensive, easily $500 or more, and is a worthwhile investment only in a higher-end house.
You can take pictures and measurements and bring them into a glass company to get an estimate without paying for a service call. They have catalogues to show you all the options.
