Same wood as the wall, with triple coat of varnish to prevent problems. Around the faucet, a solid piece of material, perhaps a solid porcelain tile drilled for the taps. Keep it very simple.

As you rethink adding a fixed window, consider either a fixed window that is the long horizontal kind over the shower/tub surround and/or an octagon one with stained glass for the dressing room. https://www.google.com/search?q=images+for++octagon+windows&biw=1366&bih=673&tbm=isch&tbo=u&source=univ&sa=X&ved=0CCIQsARqFQoTCOaJ69fb28gCFcYVPgodogsLDw You could add a couple of pairs of shutters to create a pair of faux windows that look as if the shutters are closed. If you don't want a window that opens on that wall, you might consider having a fixed window and shutters that are louvered to let in some light while protecting your privacy. You might also consider a faux gable with a faux window, perhaps functional as part of the venting system for the bath.

Actually, just reread a bunch of the tile places and they all say not to use in shower. Bummer - that's out. However would still love ideas on what to do around it and if anyone can think of a way to update the acrylic walls? Or maybe it won't be as bad with new fixtures/shower curtain in better lighting... fingers crossed... just trying to get ideas together.
