Possible to extend wire to shaver socket?

john2k · 2026-01-02T22:48:05+0000

I need to move a shaver socket in my bathroom which is in a stud cavity. But the wire falls about 50cm short. Is there a way to extend this? I have the cavity open at the moment and hasn’t been backer boarded yet.

Use a maintenance-free junction box.

And the cable route must be a vertical or horizontal route to/from the new location. No hidden dog legs in the cable route.

Any suggestions or examples of what is a maintenance-free junction box? What cable should I use? 2.5mm twin and earth?

Go to your favourite electrical supplies website and search it for “maintenance free”.

The same as the cable you’re extending, probably.
