I had indoor plumbing and baths as far back as I can remember. I was born in France, the daughter of Air Force father. I know they lived off base in a house, we were on the top floor and farm animals lived in a barn on the first floor. I think it was an outhouse set up. Both of parents were raised with an outhouse. This would not be strange to them.
We were there for about a year when my Dad got transferred to Germany were living high, indoor plumbing, ringer washer etc. I do not remember it but my sister does. She still bears the scar of putting her little hand through that washer.
After that, the only time we experience the outhouse was at the grandparents. My Fathers parents had a sweet little cottage on the shore of the Cheasapeake Bay/River, no indoor plumbing but a hand pump at the
kitchen sink. It was not really a kitchen. Just a small space with the sink and pump and maybe 3 ft of cabinet, countertop and storage under the sink. I do not remember if they had any kind of fridge or stove.
It was tiny, you went in thru the door, the so called kitchen/eating area with the table and chairs, then left was the family room which also served as the bedroom for my Dad and Uncle.
In the right of the kitchen area, back in the corner was a tiny door. You open that and there was a tiny dark stair case. You went up those stairs and my grandparents bed was there in the tiny attic area. It was like a little doll house. I remember my Grandma keeping little pots around the lower floor. In her older years she had bladder problems and couldn't get to the outhouse. She had candy dishes everywhere, filled with butter mints, they were her favorite. I never had any other type of candy in her house.
Of course all the family there is gone now, the magical, beautiful place of my childhood is gone, sold to others. I still have the memories and they are priceless.
