Exit the bathroom, go up the stairs, turn right, walk down the hall, enter the room at the end of the hall, wait at the sculpture.
Turn right, go through the doorway and head up the stairs. Once you get up the stairs to the landing turn right and head through that doorway. Go into the room ahead of you. There should be a door to your left, and in front of you should be a fireplace with a portrait of a man above it. You are at your destination.
Walk up the stairs. At the top of the stairs take a right and enter the room at the end of the hall. Stop in front of the large shell on the floor.
