I think it depends on the age of the house; places built well before fridges were common frequently have walk-in pantries, usually with a stone slab shelf at the end to try to keep things cool on. All the police houses I lived in as a child (ten of them) had them. I'm currently staying with friends in a house built in 1820, which has one. OTOH I suspect some houses had them converted into downstairs loos where that was feasible.
