Bobby's Panic Room
From Super-wiki
Sam: You built a panic room??
Bobby: I had a weekend off.
In 4.02 Are You There, God? It's Me, Dean Winchester, while being attacked by the Witnesses, Bobby leads Sam and Dean to a safe room in his house. It is a cylindrical room, completed lined in iron coated in salt to keep spirits from entering. In the roof is a large extraction fan, below which is a grill with metal work in the shape of a Devil's Trap.
The room has a bed, and appears well-stocked with supplies and equipment. There is an iconic poster of Bo Derek from the movie 10 on the wall.
At the end of 4.20 The Rapture, Dean and Bobby lock Sam in the room, after Dean finds Sam has been drinking Demon Blood.
