It was popular in the USA too, especially in the 1970s, considered a sign of luxury.
Atch paleez.......lol, hardly.
Lafayette, Louisiana
Lafayette is Cajun country. (Blacks mixed with the French people) so I guess it is possible as they aren't the brightest people in America.
NEVER have I seen carpet in a bathroom and I used one at least six times a day in the 70's living in at least six different States.
I have tile in mine, with a small throw rug, so I can use bleach water to clean and kill any bacteria or mold that may want to grow in a damp area.
The water tank on the throne sweats in the hot summer from the ice cold well water that fills it, the shower always splatters water out of it and boys can't help but splatter when they take a leak just inviting bacteria and mold to grow.
The stench after a month would be unbearable and most likely encourage the house dog and cat to start using it for their relief also.
Only one word for a carpeted bathroom......"YUK !" especially if you have kids.
