Its impossible to get zaped if properly installed, its isolated and the voltage is low, even if it did escape ir would disperse before reaching you. Showers run with gas, american showers, have way way way more accidents and deadly accidents than eletric Chad showers. Even so, I would rather suffer a little zaping than being boiled and scalded to death because someone flushed the toilet in the other room.
Also, about shit bins, just trade the bag everyday and it won't smell.
