I installed a tile shower and backsplash in this bathroom in Ellettsville, Indiana about a year ago. (Read about it here.)  They invited me back to finish the bathroom with a tile floor as well.

The existing hardwood floors were in fine shape, but they wanted to have tile throughout.  Tearing up the hardwoods was a bit of a chore because I found that it was all glued down.  Rather than coming up a board at a time every piece splintered and came up in tiny bits.  At least it was a small bathroom, right?  :)

The design was easy because I just continued the shower layout into the flooring from the curb.
