What’s wrong are the regulations. Over the last several decades, through hundreds and thousands of tiny edicts, Americans have had terrible experiences in the bathroom and with water use generally imposed on them by bureaucrats who think they know things like:
A showerhead flow can’t exceed more than 2.5 gallons per minute (gpm) at a water pressure of 80 pounds per square inch (psi)
I’m old enough that one of the reasons to visit America in that dim and distant past was to enjoy a shower that actually worked, had some water in it.
It actually was a thing – “their showers are different your know” went along with the wonders of soft toilet paper as proof of the wealth of that society.
