I have heard this both from young children and people whose first language wasn’t English. I worked with a cook from the Phillipines who exclusively used the phrase “do the sex” instead of “have sex”. As in, “Yah, I heard they did the sex!” or “I bet those two will be the doing the sex later”.
And I have or take a shower, and have/take/draw a bath. No one term is used more than the other.
We have a shower (stall) in our house and take/have a shower.
We have a toilet or commode but NO bathroom since we do not have a tub to take/have a bath in.
Never figured out how people got to saying “Going to the bathroom” in any and all situations where there were NO kind of showers or tubs present.
Sloppy talk?
The bus trip to London (as I recall) took over an hour. It seemed every house along the way had a flower garden in the front yard. The route didn’t travel along a major highway (I think), and we wound through two, three (or more) very quaint, very British towns, whose charm was well beyond anything I’ve ever seen since. I was entranced on every trip.
This was 1953-54. WWII was just 7-8 years earlier, and yet the people were still much more innocent then, than they are now. But I’ll bet they’re just as loveable.
