I see trim clips, so if guess the mirror isn't actually glues on. If it were me, I would want it centered, so having it cut smaller (and maybe shorter, it's a little overpowering) would be good. If you're switching to two lights, I would also consider hanging two mirrors.

I meant attached. I do not want to risk dropping this bad boy.

I considered the two mirrors but like how the one makes the room feel big. Plus i would have to deal with sinks not centered on doors issue, which leads to mirrors and lights centered on vanity or sinks issue. Figured one mirror with two lights wouldn't drive me as batty.

How wide a frame are you thinking? Any way you could incorporate that outlet into the frame? It might involve moving it to the right and patching the sheetrock. With a wood cover plate stained to match, it would barely be noticeable. then you could make the frame cover the excess on the right, but flush with the mirror edge on the left. That would require a 2" or 3" wide frame, but that would be close to accommodating the outlet.

eta: Proof you can find ANYTHING on the internet, I found this pic of what I mean. I wasn't thinking of such a wide frame, but it gives you the idea. You could also use fancier molding for the frame.

eta2: THIS is more like what I imagined - I can't believe I found TWO pics:

I think..as somebody who had to deal with a somewhat similar problem..leave it as is..no frame-will emphasize it being not symmetrical..two lights are a very good thing to go with-place them as if was symmetrical, higher than the now-fixture of course...style to your liking, balance it out a bit-say something pretty and high on that left side..you'll forget about these 3 inches in no time

If you are afraid to move the mirror then don't frame it. Just find lights you like and go with that.

What would it look like if you just centered the light on the mirror? (and not frame the mirror)....Two lights might be better since you have two sinks. Not sure I would frame the mirror unless you use something narrow.

I did a little thinking on this.

Light socket to left of mirror- it is attached to a stud on the right side of the little electrical box. I am going to replace it with a 3 capacity box, putting the socket in the spot on far left, then patch/cover the other two. This will allow me to move the mirror down a few inches to be centered on vanity. I will still have room between it and framed the mirror.

Lights- I will then be able to center the lights on the vanity/mirror, not on the sinks. But the original hollywood light had one wire in middle of fixture. To install two lights I will need to split that and run through the studs to get to new opening for new fixtures. I was not thrilled about patching drywall to do this. But...... if I remove the mirror ( which is not glued as originally thought) I can open up the wall behind the mirror, do the split, bore through studs, run new wires up to the new fixtures holes. Then I patch the wall which will be covered by the mirror so it doesn't have to be perfect!!!!

It is a lot of work but will be worth it in the end. Can't wait to finish and post pics.

Ilikefriday- thanks for the mock up. For some reason the one with frame wasn't showing until now. I love the frame dark. You just helped me make up my mind
