Need advice about a bathroom light electrical box extender

Hey guys/gals,

First time here. My wife and I just put up shiplap in our bathroom, and now where the light was, there is an inch (thickness of the shiplap) where there is no electrical box--wires are exposed (see attached photos).

My question is, what do I need to extend that box out? Is there something as easy as an "extender" for this type of box??

Thanks all!

Welcome to the forums.

That fixture looks like it's missing a back box.
All the wiring needs to be contained either in the back box or the electrical box.

I've never seen a plastic extension ring. You could use metal but it might be too long.
I did see plastic mud rings which may work.

Yes the box needs to be extended. Through a flammable wall covering like wood, the box needs to be extended flush to the wall surface. Arlington makes an extender that will work in your situation, but you will probably need to fabricate a spacer to support it.
