I STRONGLY suggest you not purchase this mirror.  We bought it and had it professionally installed.  Within 2 months dark areas began to emerge on the mirror, as if the silver chemical that's used to make the mirror degenerated or failed.  Since the problem became apparent more than 30 days after we bought it, Wayfair said they couldn't do anything about it.  The manufacturer is in China.   The Wayfair specs for this product says it has a  year commercial warranty.  Repeated attempts to get a response from the manufacture have failed thus far.  We are EXTREMELY disappointed with the quality of this product and our inability to obtain a refund/replacement from either Wayfair or the manufacturer.  If zero stars were an option, I'd select that.
