If it were up to me, I'd have wood floors everywhere. We did discuss—albeit briefly—putting wood in our full bath when we remodeled it a few years back. The discussion when something like this:
Me: It would look beautiful.
Him: Yeah, but think about potential water damage.
Me: You're right.
See? Brief. In the end, we chose tile.
In the makeover featured here, the owners were more courageous (or quixotic, depending on your viewpoint). The rich, brown flooring they chose to install, coupled with the serene blue on the walls, gives the bathroom a 'spa' feel without being pretentious. Gorgeous, yes, but would you have the guts to put a wooden floor in you bathroom? Or do you fall in the 'impractical' column?
