The Bomb Room is a room which is packed with time bombs, hence the name. It is presumably located in the basement of Phil's New House.
June and Jessica were tied to chairs in this room in the episode Depart's All Yours. After Jessica fled the room by means of exiting out of the simulation, June then escaped by having Slim free her for $50. Although she probably escaped, June was apparently badly burnt by the explosion, as evidenced in the beginning of Just Passion Through.
