Any frame shop can create a framed mirror for you. Or, your cabinet maker can probably create a frame for you that matches the vanity and you can source the mirror from a glass shop.

Ronbow has some nice mirrors. We were at a bath showroom and she showed us their stained wood samples, so you could possibly find something to match your vanity.

If you didn't have a custom vanity made, you can go to Michaels or any picture frame shop and have wood frame made to exact size style and color you wish. They will probably be able to put a mirror in it too. Or take the frame to a glass/mirror shop and ask them to mount a mirror in it. You can even specify how wide a beveled edge you'd like.

If you have a GardenRidge near you, that's a good place to start. Homegoods, TJ Maxx, Burlington Coat Factory, Kirkland's, & Hobby Lobby all might be able to help too. Online, I would try Overstock.com, Wayfair.com, & Hayneedle.com for online shopping.

Hope this helps!

Lowes. I looked everywhere to find two mirrors for over my vanity, and I finally found the perfect match at Lowes (the Fanella). You may have to try a few to get the right color combo of brown versus red/purple.

most cabinet companys sell mirror molding that matches all of their cabinets woods and finishes... then you can just buy mirror glass from a glass shop (i got mine from the place that made our shower glass door) and have them cut it to size and bevel it if you choose...

Thank you so much for all your responses, very helpful. I'll do what you suggested.
