Replacing Bathroom Light with Fan
 
I'm replacing a bathroom ceiling light with a new exhaust fan. This is the kind of fixture with a built-in light in addition to the fan so I won't need a separate light fixture.

There's an existing junction box. It looks like I do not need a junction box for the fan (and indeed it looks like it would be in the way of the fan housing). Is that right?

What do I do with the existing junction box? There are several wires that connect at the existing junction box location. I removed the ceiling drywall as it had water damage, so I can see where they go--at least one goes to the wall switch, it looks like one goes to a GFCI outlet in the bathroom, and one set goes to the vanity light and outlet built in to the medicine cabinet. And of course one was for the light fixture I've removed, which I will use for the fan.

I understand that it's against code to cover up a junction box with drywall. What's the safest and most aesthetically pleasing thing to do? Should I just cover it up with a junction box cover? It will look a little funny on the ceiling, I think. Can I use the fan housing as the junction box? Any advice would be much appreciated. Thanks!

Do you have attic acess?

If so, then undo the nails, add a short lenght of wire for the fan, place a cover over the box and nail it out of the way.

No, this is a condo and there is a unit above. I do have full access to the ceiling now though so could move the junction box, etc. I guess I want to know if that's really the only option--to keep the wires in a junction box and just purchase a junction box cover. If so that's what I'll do--I want to make sure it's safe and following the code.

If you know where both ends of the wires go, you can rewire and get rid of the jbox!

Given the size of the junction box on the fan this is the only way to go.

I think this is where the power comes in from the breaker box. There are a few armored cables (bx cable?) coming in to the box that have un-colored, insulated wires inside, and some newer-looking black cables appear to go to various other locations as described above. What does the rewiring involve, and is it a reasonable DIY project? Would I just install a new box near the outlet and re-route the cables there, for example?
