Danger of Electrocution

Everything in my house is old, like me, but I feel that my life-experience is up to dealing with them.  I like to soak in the bath in the morning and listen to the radio, plugged in in the corridor just outside.  Recently it has taken to talking very softly, so I put a stool in the doorway and listen to it from there.  However I am conscious of the danger.  Years ago somebody I knew electrocuted themselves just by adjusting the radio while in the bath.  Probably this was because it was before all plugs were earthed, but there must still be a reason why there are no electric outlets in bathrooms.  I am very, very forgetful, but did not forget not to touch the radio while soaking.  I wonder if this is an out-of-date precaution?  Decided not to put it to the test!
