A bathroom begs for transformation.

When I purchased my home some 30 plus years ago, the bathroom on the second floor consisted of a sink and a clawfoot tub.  The toliet was in another room referred to as a "water closet."  My favorite things in the room were the porcelain towel bars and the sconces on either side of the medicine chest.  Which, by the way, was slightly high for someone 5'2" tall.  That explains the stool you see next to the sink.
