I want to install modern lighting in my master bathroom. I currently have fluorescent lighting surrounded by framing to hide the lighting fixtures.

Problem is, since my home is close to 30 years old, the conductor feeding the fixtures comes straight out of the wall, without the presence of an electrical box (please see photos posted at: http://homepage.mac.com/fzmann/FileSharing1.html)

Furthermore, the wiring is about 18 inches away from the center of the sink (refer to photo #2 at the above link).

If I paid careful attention during my residential wiring class, I think I need to:

1. install an electrical box where the current conductors are coming out of the wall
2. install an octagonal/round box directly above the sink
3. pigtail the conductors from the first box to the second box
4. cover the first box with a plate
5. install my fixture(s)

Could I please receive some feedback, or commentary on my issue? Also,

1. assuming that the electrical box above the sink is not attached to a stud, will a remodel-type box provide sufficient support for a lighting fixture (about a 24-26 inch brushed metal fixture, nothing extremely big and heavy)
2. I know building codes vary widely by area, but would this type of work require a permit where you live?

Thanks in advance

Any new electrical work usually requires a permit, check with your local building official.

The old work box cannot handle a large load. The drywall will be supporting the light, not so much the box. It should be able to handle 10-15 pounds easily.

There are round old work boxes with expanding bars that may be used if the fixtures weighs much more.

If there is an attic above the bathroom, why not bring the cable up there and splice it in a box to extend it instead of having an exposed plate?

If not, then that is what you must do is to have an exposed blank plate, as burying splices is not allowed.

Other than the comments I have made, your plan seems fine.

tkrussell,

Thanks for your feedback.

Since the wall the light is on is an exterior wall (on the other side), the pitch of the roof doesn't give me much room to operate. My spare bathroom, however, has only interior walls, and plenty of attic space, so I will definitely try to work through the attic, as you suggest.

The blank plate will probably be covered by the base of the fixture I'm planning to install.
