Why do we have the two prong sockets in bathrooms even though they are 240v?

is it permissible to use a normal three prong 240v socket?

No, I'm afraid its not. The only 240V socket you can use in the bathroom is the type that has an isolating transformer inside. It generally is the size (front plate) as a double socket and it has the two holes (for the two prongs of the appliance. There are only two holes because any device has to be double insulated and doesn't therefore require a protective earth - the third prong. Such sockets are suitable for driving shavers and toothbrushes. The UK has a very conservative approach to safety when water is around. You won't find this constraint in many countries.

Thanks buildersmate. At least it make sense now.

I've never iundertsood why plugs sockets aren't allowed in bathrooms. If it's a question of there being water around, then this makes no sense; there's far more water around in my kitchen and more plugs sockets than I could shake a stick at!
