Restoration Hardware. I have one. Nice quality.

Below is a link to an online source . . . We saw the style pictured at HD. Broan makes quite a few different styles. Good luck finding what you want!

Here is a link that might be useful: mirrored medicine cabinets

Pottery Barn too, if I understand what you are looking for.
The one I got from HD was NOT great quality.

The master is getting the PB ones, they are very nice, sturdy, solid.

Actually, we cut out on the side to make room for an outlet so that any items that require plugs that recharge (especially for my DH who is a clutter hound), can sit inside the cabinet and not on the counter!

I will post pics when it is finally all in (I hope Thanksgiving!!)

Robern, a Kohler company, makes these. You can select any type of picture frame to go around it. There is a leather one that is truly decadent and way to expensive. Roberns are solid quality, don't rust and the quality of the mirror is very good. I see a lot of mirrors that look wavy from Restoration hardware and Pottery Barn lately.

Good luck!

Another recommendation for Restoration Hardware. They have bath sales twice a year where you can get a 20% discount.

We have a Robern, and are very happy with it. There were many different frames to choose from, and an endless array of options. You can get different sizes, different depths, electrical outlets inside (nice for electric toothbrushes, etc.), magnifying mirrors inside, and the list goes on. The only downside is that they're a bit pricey, but it's very high quality.

Thanks all for your replies. I will check your suggestions.

We want the mirror to be flush with the wall so we can add our own custom molding around it and sconce lights on both sides.

Another nod for Restoration Hardware. I just installed mine last night along with RH sconces and I couldn't be happier. Excellent quality, very sturdy construction.

A warning about your plan. I considered the same idea for the framelass glass medicine cabinet in my other bathroom. It's nearly flush with the wall sticking out only the thickness of the door. If you slap a frame around the door, it can't open because the hinge is flush with the wall and the frame on that side would hit the wall. Part or all of your frame would have to be mounted to the wall to make this work. It can be done, but takes some planning and likely some fine woodworking skills.
