I'm just finishing out a new bathroom and my bride would like a full mirror
behind the vanity. This will require cutting a hole in the mirror for the wall
mount light. I know I can get a glass company to make the mirror and can think
of several possibilities for DIY as well:
1) Take a new glass cutter and score a circle, then try to tap it out.
2) Drill four holes with a ceramic/glass bit, score between them, and tap it
3) Drill a bunch of holes on the outline of the hole and break the glass between
You will never get a scored piece of glass out cleanly, particularly if
it is not a straight line. Most likely the crack will propogate where
you dont want it (they do make it look so easy in the movies). Try a
carbide hole drill bit (they make them up to several inches in
diameter), that may just do the trick, but be careful about tearing up
the mirror coating on the back when you break through. Alternately you
could try drilling one hole with a carbide bit and then slowly saw the
hole out with a carbide rod saw combinded with a coping saw frame.
This works quite well if you flush with water as you cut for
lubrication and debris removal. If you are using a flange to cover the
hole then you will be in good shape, otherwise you will have to polish
the rough edges with a diamond tipped Dremel bit or similar. Either
way you go, practice once on a scrap piece of glass or old mirror. You
probably wont be lucky on the first shot.
screw up a lot, and they do this every day. Cost of doing business for them-
one reason mirror/specialty glass prices are so high. After you bust the
first blank and have to go back for another one, the price for them to cut
the hole will seem cheap. Give SWMBO a choice- either pay for the glass
company to make the mirror, or move the lamp to the adjoining wall or the
IMHO, of course, and YMMV. Who knows, maybe you have the touch.
If you're going to have a glass company make the mirror, then have them
make the hole at the same time. Less hassle on your part, and they get
to make the "mistakes." Give them good measurements and it will be a
piece of cake.

Only one suggestion. Have the glass company make the hole.
How much is the mirror going to cost and how many will you need to practice
OK, two suggestions. Make the mirror lower that the fixture. Mine is about
3" below the box and it still goes over my head.
