Any carpet in the bathroom ends up smelling like urine, especially with little boys in the house. Heck big boys too. At least with a rug you can through it in the washing machine. Carpet not so much. My grandmother had carpet in her bathroom. And those weird soft toilet seats that eventually cracked and would pinch your backside when you sat down. Wouldn’t recommend at all.

Worldwide? Never seen in my life even in media.
