Not quite, as the flush has not been invented yet. However, Tudor World has added all modern conveniences of the time - an indoor toilet with basket ('bum bucket') and straw, which can easily be added to your midden or thrown out of the window! As necessary!
Toilets were called 'Privies' and were not very private at all. They were often just a piece of wood over a bowl or a hole in the ground.
People would wipe their bottoms with leaves or moss and the wealthier people used soft lamb's wool.
In palaces and castles, which had a moat, the lords and ladies would retire to a toilet set into a cupboard in the wall called a garderobe. Here the waste would drop down a shaft into the moat below.
