Is there a creative way to do a tub surround rather than tile or plastic, like could you use painted composite

Question

or red-guarded and painted concrete board or, well something else that wouldn't rot?

Answer 1

the concrete board would have such unfinished edges... you could get a mirror cut to the size you want (at least 4" high) with beveled edges, and glue it to the wall.  that would be different.
