I'm renovating a second floor bathroom. The room is going back to studs. I have easy access through a shaft to the unfinished basement and breaker panel so can put in all new cable and boxes in this room.
One existing junction box, for a ceiling light, is located near an adjacent room and contains a cable going into that room, supplying power there. That junction box is located where there will be no ceiling light in the renovated room (because it's butt up against a wall). The cable going to the adjacent room is short, there are only a few inches to play with in the bathroom. The attic is finished so I can't get into this from there.
What are my options to continue supplying power through this cable to the adjacent room from the renovated bathroom? I am in NJ, USA.
- Break open the ceiling in the adjacent room, and maybe a wall too, trace this cable back to the next junction box, and replace it with a longer one. This is the option I want to avoid.
- Is there an approved way to connect power to this cable and hide the connection in the wall? I know that is generally not allowed. Are there any exceptions and techniques for any situations? For example anything like the "maintenance free" junctions allowed in the UK?
- I could leave the box where it is in the ceiling and cover it with a decorative blank plate. Ugly but probably the easiest and codiest way to do it.
I will have a pro do this work, and will need to follow their advice, and suspect they will choose option 3. I'm looking to understand options at this time so I can design and locate fixtures and things appropriately, and understand my options.
