Go through closest doorway. Walk towards tub, then go into room with toilet.
Exit the area though the double arched doors nearest you and continue forward into the bathroom ahead of you. After entering the bathroom, go to the right into the small room with the toilet.
Turn left and walk forward towards the white tub. Turn right towards the first room that is next to the white tub, not on the corner. Walk inside the room. There should be a toilet bowl visible, and stop there.
