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

royal family
I am the daughter of the King and Queen. I am known as the princess of the village. I will be married off to a prince from another village very soon. A peace treaty will closely follow the wedding.
Father! I've spoken to you about this before. I need my privacy in the bathroom! Well we only have one royal bathroom! Where else shall I go to empty my royal bladder? You could at least wait! A lady needs her privacy, especially in the privy! And besides, you leave a malodorous reign in your wake. How dare you insult the royal bowels of the kingdom! You know I am a fearless king! I don't hesitate to charge into battle. Especially when nature calls... Clearly, Father! And normally, I'm happy to have you with me all the time. But ladies have special needs. But I really can't hold it....it's an emergency... Oh, fine... I'll wait here while you go, but make it snappy. I really hope it's just pee. Thank you! Now hold this while I go relieve myself.. Seriously? I'm not holding your scepter while you take a royal dump. I promise it's not. It would be unfitting for the king to relieve himself on the sidewalk!  Yes yes, I understand. Just please hurry hurry. My bladder is about ready to burst, too.  See! I was done before you could even blink! Now carry on with your business here..
