Extending cooker switch socket

[paul-doityourself]

I want to move a cooker switch and also a ring main spur about a meter away from where they are.
They have been put at low level in a stupid place, the wall has a shower fitting on the other side so if it ever leaked it would leak straight onto the sockets!

Can I just use junction boxes to extend them or is there a better way?

They have been put at low level in a stupid place, the wall has a shower fitting on the other side so if it ever leaked it would leak straight onto the sockets!

Surely the wall is watertight enough?

I think you're being paranoid. Under our shower there's about 3 lighting junction boxes. Under the bath theres a couple more. On the other side of the shower wall, against the ceiling downstairs there's the fuse box, meter and cutout. On the other side of the other shower wall, alongside the shower, there is a cable fastened to the wall which supplies power to 3 other houses, with a joint on it to supply our house.

And sticking junction boxes there instead of sockets is only serving to make the installation more complex and more to go wrong. They'd have to be accessible anyway!
