shower glass
So this kind of glass would be fine. I think it definitely illustrates your point, however, that the use of frosted glass changes how much you actually get to see of the shower tile. It argues, IMO, in favor of not trying to do anything fun, fancy, special, or funky in the shower since it will only be visible if the door has been left open. Which I'm totally fine with. The only other comment that comes from this picture, is that IF I've chosen a tile for the shower and I want to see more of it, then I need to incorporate it OUTSIDE of the shower, like they did here. Which is also fine.
So....do you have to go beach-y look for frosted or treated glass to look right? (shower glass as well as panel door are frosted/whatever)
