THE MINI'S | GUEST BATH REMODEL

We have lived in our house now for a little over a year and are finally ready to dive into the bathroom re-models.  Our first one will be a smaller guest bath on the first floor.  I want to do a clean, elegant, but also colorful space.  In my opinion, wallpaper is a must in a small guest bath.  It is a space where you can have a little fun!  Which inspiration above is your favorite?
