Is there a standard height for a wall fixture over a mirror above a vanity?

It depends on the size of the mirror to a certain extent. Generally 6.5' to 7' should do it in most cases for an 8' room. You want the lowest part of the fixture to extend to the top of the mirror. Which are you doing, installing a light or the mirror?

80" to center works many times, but like ballenger is saying, mirror, or the type of fixture may require a different height. Some other heights that work:
Recepticles, 18" to center.
Porch and bath lights, 80" to center.
Switches, 48"
And kitchen and Bath counter top recepticles 42".
Vanitys and Tile May determine height adjutment for countertops to not be halfway on tiles or vanity.
If your family is taller or shorter you could move to a more comfortable height.

I forgot to mention that it also makes adifference if the fixture is a globe, hang down or standing up glass fixture. Strats other measurements are worth saving for future work. Old vanities were 32" tall but now nearly all come at kitchen height, 36". Styles and people change.

Typically what is done during rough in is the cable is simply dropped left to hang free in the empty bay at the center, or desired distance apart.

Once the sub floor, floor, base cabinet, counter top, backsplash, exposed wall , and mirror is all installed, the desired height is marked and an old work box is installed, cut open the wall and pull out the cable. Eliminates any error or change in the items below the fixture.

They won't let us Leave it like that down here, I have done that for Flat screen tv's, where customer has not chosen TV or Mount, and drywall need to go up. This allows you to fine tune receptacle location, this way you are not mounting TV where receptacle allows. The TV can be mounted anywhere you want.

Sometimes leaving just the wire is a good idea, but I see issues with it in some cases. One being the plumbing. One job I had, my customer requested exactly what TK suggested. I called the AHJ, and he said, "no go". Then followed it with, " I would like to see the wires in a box. Heck, I could have told him we where installing fluorescents and got away with it ;).

Yet, we installed the boxes with extra wire, and changed it after the inspection ;)

Sometimes you got to do what you got to do. I think many Electricians Go into the Grey Area of code, yet the results are safe, which is the purpose of code.

I can understand why inspectors are wary of leaving a dangling cable in a wall. Being so thourough and trusted by inspectors, I never had this issue.

Talk about thourough--I believe I'm losing this important part of me. Heck, I've been missing things lately.

Don't worry, when you get top be my age you'll forget that you are mising things.

LOL! I hope not! That way I can correct them!

LOL! :)

Correct what, I don't remember what we were talking about. Have a great week.

I love to learn, Love to teach, Get to do both here. Thanks, Take care

Wow, thanks for all the input on the original question... I am impressed, this is my first question asked in this forum.

And this is when we all agree. Stick around and see when we don't!

I think sometimes we forget the Poster, glad you stuck around.
