The round fixture base that goes against the wall is 5 inches & it would be mounted on the wall above the sink, not on the ceiling.......There is NO hole except the 1/2 inch tube with wires sticking out....the original fixture was a flat thin chrome cover with 3 large bulbs, nothing else, must of weighed a big 1/2 lb.
My husband is fit to be tied & wants to hire someone, but paying someone to put up a $45 light is ridiculous to me. Home Depot sold us the flat round metal plate & a univeral plate but there is NOTHING in the wall but sheetrock, thin sheetrock to boot! Are we supposed to make a large hole to use the thing Mark suggested in the previous post? What if the fixture doesn't cover the hole....ack!
Thank to everyone who has or will reply...had no idea a MH was so much different.
P.S. My son says to make a hole behind the mirror to insert the support bracket & then put the mirror back up after we patch the hole, how fesible is that? The plate glass mirror is paper thin & pretty large about 3X4....
