Can somebody explain the idea of not wanting to wash in the bathroom?

I was born in 1957 and lived in a back to back house in Leeds ( 2 up, 2 down) until we moved in 1965. The house didn't have a bathroom. The toilet was in a yard where there were 2 toilets for every 4 houses (it was a terrace of 12 houses). My brother was born in 1964 and I remember he was bathed in the sink in the kitchen! We had a tin bath that I was bathed in and I think my stepdad used now and again, he was in the building trade and he always washed in the kitchen sink when he came home from work. I remember being dropped off a my grandparents a couple of times a week, they lived two doors away, and my mother and stepfather would go to the local swimming baths. Part of the building had hot baths, (which is where my parents were going), where you paid to have a bath, and a wash house where my mother went every Thursday afternoon to do the laundry. We moved to a new high rise flat in 1965 which had a separate bathroom and toilet. Luxury! We moved back to the area where I was born in 1972........to a back to back house! The small bedroom upstairs had been converted into a bathroom and my brother and I slept in the attic which had been converted into a bedroom.
