thanks, mill. I was thinking if it cost 50 bucks for each panel and more to replace the hinges etc, I could be over 200 and might be best to just replace.

Who is the manufacturer of the cabinet? If Kohler or robern, they sell replacement parts for their items.

The mirror itself in those pcs should not be more than $50 total and that is probably high

homepro.. I don't know. I cannot see a name, and haven't pulled it out of wall to look yet. It was purchased with the vanity and may be the same brand, but I don't see a name on that either. Thanks.. I will look at Robern and Kohler's websites

Millwork.. good to know! Someone at the hardware store suggested it might be expensive to replace the mirrors..

I have a medicine cabinet with three mirror doors. They measure 10"1/2 x 26" each one is beveled and it sits in a small sleeve at the top and bottom of each one a small screw holds it in the sleeve. They slide in. Very easy to replace. I just can't find them anywhere. I bought the medicine cabinet about 15 years ago at Home Depot. Now I can't find it there.

I brought my one panel to a glazier that I found on yelp. He quoted $150 to replace the mirror and re-attach it to the to the door. I preferred using a glazier instead of replacing the whole unit not just to save a few bucks on the unit but to save on all the disruption to my bathroom. at this stage I prefer less drama and more serenity.

Can you contact the manufacturer and utilize the warranty to get a replacement?
