If it's a small bathroom, I would go with #1, the white will make it seem bigger in there , yet it still has the theme of the outhouse. Also like someone else mentioned, it will be a lot lighter in there with the plain white on the top instead of a print. I have a dark curtain on mine currently and its so much darker when I'm in there trying to shave my legs.. I have to open the curtain hehehee.
#1 i my choice .... the others are cute though but such big patterns will really dwarf the room.
