You may never have seen one in the USA, but electric shower heads are surprisingly common in Latin America.
The first time I saw one, it was in Mexico, when I heard a loud pop and then the screams of my wife, who shot from the shower like a bullet screaming,
¡Ahi! Mi amor, ¡explotó la ducha!
(“the showerhead exploded”)
I didn’t believe her, until I looked. Indeed, it was smoking and smelled of a short circuit. Since then, I have grown accustomed to finding these in hotels and old homes, where instead of plumbing hot water to the bathrooms, they wire a kind of on-demand lukewarm heater in the showerhead itself.
You don’t need much hot water in the tropics, but just in case, don’t adjust the nozzle, there’s no inline GFI breaker!
