Simon,

You jest - SWMBO did initially want a TV in the bathroom, but when I saw the prices, I suggested that a battery powered portable would be more suitable  :wink:

Anyone know how to build a Faraday cage  :?

The front door on an old Microwave is The Faraday Screen. which would be a good Idea for the screen on the tv. All you have to do with the rest is case it in with a tin box. I can see some Garage time coming in...

Jimbo:
I was planning (if nothing easier works !) on building a cage around the shower pump - is it just a metal box thats bonded to earth ?

Yes that is correct. GOOD EARTH. Have you not thought that the shower may be faulty. It may be worth taking it back and getting it exchanged. There is nothing to lose besides the shower for an hour. May be worth a try.

NeilWilson:
Faraday cages have a mesh size relative to the frequency you are trying to shield from - ie at a particular freq a bit of chicken wire fence does not work as well as microwave door screen etc .

One of the main disturbances we found on a tv/radio in our first house was the central heating motorised valve controller had a relay where the internal contacts were breaking down & becoming resistive thus sparking each time the motor reversed.

There are some filters/shunts that can go across terminals - bit like car ignition suppressors - I think Maplin/RS had some.  Cheers.

Neil
