If you're looking for tiling ideas, here are a few pictures found via Flickr
These blue/grey tiles are pretty funky. I like the uneven layout and mixed color palet. Note that the dark colors in these tiles will only work in a bright bathroom - avoid these if you have a small bathroom with out natural light.
This examples shows accent tiles, used only in a horizontal band across the bathroom. I dig the green and white combo .
This one is inspired by the 1970's... it's a little too Brady-Bunch for me, but a neat idea.
