If the plug was on a GFCI outlet, it would trip once neutral and hot are shorted.
If it wasn’t on a GFCI outlet, it would be an inefficient water heater. Current is inversely proportional to resistance, and the inch of tap water between both conductors has a significantly lower resistance than the human sitting at the other side of the tub. At American voltages of 110V, the worst thing that will probably happen is the wires heat up from the current passing through them. Now, if it only had the live wire exposed and you had a metal tub, that might be a different story…
You assume the neutral wire is present and connected to the neutral prong, as it is in typical appliances. If I were to make this ducky, I wouldn’t connect anything to the neutral or ground prongs in the plug. Indeed, I’d connect all three wires in the cord to the hot prong.
But yeah, probably ok if the water isn’t too salty
If you’re going to be passing a current through your bath water, you would want the bath water to be as conductive as possible. You don’t want the salt water in your body to be the path of least resistance. You want the current to flow around you, not through you.
The funny part is that it wouldn’t even work.

It’s got a British plug so it’s at least 200 volts.
But yeah, probably ok if the water isn’t too salty and you stay away from touching the electrodes.
I’m still not getting in with one though. At over 6 feet, I take up the whole tub + most of the time anyway.
