The royal bathroom is a stone room with a long wooden bench and several holes and seats for royalty to take care of business.  There are some tapestries depicting rural landscapes hanging on the walls to give people something to look at.
Royal Bathroom, Inside Castle

guard
I guard the castle.  I guard the king.  I would kill to protect the royal family.
Hello sire. Pardon me while I guard you in this bathroom. I am just doing my job I don't need guarding inside the Royal Bathroom, please step outside. I am sorry sir but your father has told me specifically to watch over you, including private matters. I know...this is somewhat unusual and I have tried talking to the king but he will not listen. Perhaps I will ask where did you get your boots? They are laced with gold and I wish I had those as well. I am no sir! I am the daughter of the King and Queen and must ask you to step outside. I must have been mistaken! My apologies mam! But you sure do look like a boy with that attire and footwear. How embarrassing, but first could you tell me the history behind the tapestries depicting rural landscapes on the wall? They depict what our land used to look like many years ago. It is there to give people something to look at. How could you mistaken me for a boy? I am wearing a gown!
