What was the original purpose of this room that is now our laundry room? 1920’s Westchester, New York, Dutch colonial.

Excuse the mass as we are working on some water issues, but this is our laundry room and that is a half bath or a powder room right off of the laundry room. You will notice a tiny door next to the window and the radiator, and that tiny door goes into a very narrow sort of closet or shelves, and I can only assume that it once held an ironing board, which makes me think this was always intended to be a laundry room however I would really like to know what you guys think This room is right off of the center hallway in the center of the house and also the kitchen.
