As much as I love wallpaper, by far that’s not the reason why I believe powder rooms look more inviting when wallpapered.  Of course big part of that inviting atmosphere comes down to the choice of paper, but the enveloping feel of a beautifully finished powder room does make a guest feel welcome more than any other room.  Bare powder rooms lack caracther, there is only a toilette and a sink and unless they are not covered in expensive stones and embellished crown molding or painted in a nice color, there is no visual interest at all.  It’s also the place where more design-conservative people can test their courage and opt for more bold design choices they would not pick for any other room in their homes.  Enjoy!
