My NYC DC apartment was in 1950 - 52. The plugs were the same as AC. No ground, of course.
For nostalgia sake, the bath tub was in the kitchen, with a cover over it to use as the kitchen counter. There was no heat, but since I was on the 4th floor, enough heat came up from the apartments underneath to make it liveable. Rent, shared with a college buddy: $15/month.
