I also grew up in a Scottish tenement, where we only had a kitchen sink. We only got hot water if we boiled the kettle. Strip washes were the only option. I was sixteen before I lived in a house with a bath. My mother was one of nine children, and they grew up in a two roomed tenement with only the kitchen sink, and an outside toilet two floors down. When I say two rooms, I donāt mean two bedrooms, just a kitchen/living room/bedroom and one other room, obviously a bedroom. These two rooms were just referred to as the room, and the kitchen. As another P said, the kitchen sink was used for everything, though each family got a slot once a week, for the outside wash house, where the stone boiler had to be filled, then the fire had to be lit underneath to heat the water for the laundry. Luckily, nobody had that much clothes, towels and bed linen etc in those days. How things change.
