Can you really get an electrickshock if you shower when thunderstorm happening ?  

I think it is if the lightning strikes something in your area that spreads to the water... Just the weather alone isn't enough to cause electrocution.

To get simply electric shock from that condition is so rare. start from basic, we know water is a good electric conductor but to get perfect condition to get shock needs some other aspect too for example, the water must be flow in constant and continuously,(air is one of insulator). In reality, most of house today were have thunder grounded system build in. Urban legend? maybe but they still got percentage to get shock (1 in million ;P) actually if u bad luck.

Most houses are grounded so it's not likely that you'd even notice. The energy would run through the ground line instead of you. However if your house isn't grounded or it's ground line has been damaged then there is a danger. The lightning could run through your house & try to leave through the pipes & your in the water.. It's about as likely to happen as if you were standing outside but still, it's like giving up your homes protection.

The danger is not as great today with PVC pipes used in most houses, but if you have older iron pipes and lightning were to strike the house, yes you could get shocked.

ibuemma my son always told me that too, and then I read where when you rent you often are living in apts with older plumbing and yes shocks can happen if electricity runs up those old iron pipes. best to be safe unless you know you have plastic pipes that wou ld not carry electricity.
I also am afraid in the shower if the lights go out, and I stumble and fall I could shatter my shoulder joint replacement as I am one of the bionic people with steel and plastic joints, a break like that wou ld cost a fortune for the surgery it entailed, new joint and all. so if its really lightening I forgo the shower til the storm passes and I know the lights are not going to go out.

Well i guess it could happen if your whole house is made up of metal. And it's stricken by lightning while you're in the shower. Lol. I've showered too many times too while there's a thunderstorm and nothing happened.

You can get struck by lightening if you are anywhere (except I suppose if you are under ground). Certain places or activities are more dangerous than others, for example being on a golf course with metal clubs is more dangerous than inside a car, insulated on rubber tires.

Being inside a house is usually fairly safe. However if the house is struck, you can be involved too, depending where the lightening goes. Metal plumbing is usually grounded however, so if lightening travels to the plumbing, it is usually at ground potential and neutralized, unless the lightening vaporizes the ground wire.

Electrical wiring is frequently grounded but there are live wires which if struck allows to lightening to enter your house. The same is true for telephone wiring, it can allow lightening to travel into you house and if you are on the phone can put you in danger.

Just to be on the safe side, during a storm it is recommended to stay away from the windows, off the phone, and away from electrical appliances. I am not sure if that is true, but I certainly would not take the chance of having a shower during a thunderstorm.

Another alternative is to move to Hawaill or Alaska, apparently they have 0 deaths from lightening in recorded history. Florida apparently is the worst by far.

My mother and grandmother would throw a temper tantrum just at the thought of running water in a thunderstorm. I have neber takena shower in a storm, but i have washed dishes. So far I am still here.

i have not got any electricshock by luck by the time while shower and even dont want to experience this. i think this is really a horrible thing to get an electric shock.
i have got shock in general cases as i have touched some live wire and due to which i have the experience of the current.

I heard about that once from my step mom when she saw I was drawing a bath. I had been bathing during thunderstorms for years now but after that I'm not taking any chances. Just because something didn't happen to me then doesn't mean it won't next time.
