In the US, they're for sale everywhere. And I must acknowledge their ingenuity when it comes to toilet plunger design: American plungers have an additional "lip" at the bottom of the rubber thingy that fits into their toilets quite nicely and seals them up better than the usual plungers in Europe would do, which don't have that extra rubber lip.
Apparently the extraordinary demand for plungers resulted in better plungers, not in someone asking "why the heck are we so reliant on plungers?" and possibly making better toilets ;-)
I think the ship has sailed on better toilets in America, unfortunately. A big part of the problem is just that the standard waste pipe is too small AIUI.
