I am looking at a vertical Travertine shower wall that has that "old world" look with many holes and a honed/ satin finish (not really shiny).  It looks like the majority of travertine that is out of the box.  The house has travertine floors (different tile than the shower vertical walls) everywhere and the finish very shiny and I even saw unused floor tiles and they had a coating on them that actually looked like "liquid plastic" .
