Showers in Brazil

We have 3 bathrooms here that all have showers. As I appreciate my life I only use one of them.

Brazilian showers are electric.. fine you think.. basically Brazilian showers zap the water with electricity usually in the form of bare wires taped to the shower with insulation tape.

One looks pretty harmless but apparently when you turn on the water you get shocked.
Also you get hot water at the sink I have to plug it in... above the sink....

One seems to work fine and there are no bare wires.

The third looks like this.....

Don't worry Mum and Dad, I sent you the details of my insurance policy!!
