They are in effect a miniature swimming pool and have to be treated as such.
Even more dangerous because the water temperature is higher.
So they need filtration and chlorination to be safe.
Plus lots of cleaning.
People aren't prepared to do all the work/expense.

Or the water drained down between sessions.

Waste of space there are really, only halfwit would buy one.
