Walk in the opposite direction of the shower towards the painting of the tree. Once you reach the painting, turn right. You are now inside a bedroom, take a quick left before you even walk into the bedroom and walk out the door. You will be staring down a long hallway, walk along that hallway all the way till the first time where you can turn right, where there is a painting. Turn right just before the doorway towards the painting and stop. You've reached your final destination.
