The castle's only surviving indoor toilet is located next to the scribe's Chamber at the top of the stairs on the right.

In the late Middle Ages, the castle's officials, including the scribe, the sub-overseer, the chaplain and the dining hall, had their own chambers in the castle. The exact location of these rooms is not known.

The scribe's chamber has shelf for account books and a recess for a table top is visible in the wall chamber. in the 16th century, the scribe ensured that all those who lived in and visited the castle were recorded in the account books. The scribe also recorded how much each person was paid, what they ate and drank, how much was grown on the castle's farms, the Crown estates, and how many different types of crops and livestock were kept.

The account books were audited annually at the King's counting house in Stockholm, where the bailiff and the scribe were obliged to submit the account books. Some of the account books have survived and tell us about life in Häme Castle 500 years ago.
