A bathroom?

As I was looking at the house, it occurred to me that the large dormer in the center could be worked into the illusion of a bathroom. The little people won't have to go out back after all!

The plan forming in my mind involves a wall with a doorway in the center. Through the doorway one will see the larger octagon window, tiled floor and walls, and the end of a bathtub -- maybe with a teeny terrycloth robe draped over the rim. And maybe a commode on the other side. A light inside the room will shine nicely through the stained glass window when seen from the outside, eh?

Who ever thought this could be so much fun????
