like tiles on shower floor and walls of shower.check out these bathroom tiles. I think it would be good in a small bath to use same floor & wall tile. This is a great example (though I won't be tiling shower)
Pebble flooring is paired with stacked stone walls makes you feel like you are showering in nature! exposed piping running up the wall to the showerhead is really great look. lighting up at the ceiling, gives you great light in the shower.
