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)
A house we are considering as open tiled showers similar to this. The tile is brown (not gray) and it (thankfully) has no window right there at the shower! I love the idea of an open tiled shower! No glass to keep clean, no curtain driving you crazy!
