For some reason I have trouble adding pics to the original post, so here they are...(are you dizzy yet?)

Omg I'm dizzy. Here are directions to removing the mirror. MIRROR REMOVAL

Or, if that video made you properly fearful about the safety of DIY, a glass co will usually do this quite inexpensively. It's a lot easier to remove a small mirror like they did in the video than a huge one.

I do know people who've done this DIY, but this is one place where the money would be worth it to me.

You can do a couple of things here. You can leave the back wall mirrored (although I would remove the mirror shelves) and then hang a smaller framed mirror over each sink (like a round mirror). Or you can hang a mirror over the two sinks and leave the section of mirror over the vanity, and then just have blank wall space for the rest. Do not hang art there, just leave it as blank space to let the eye rest. But whatever you do, I would remove the large mirror sections over each sink area.

I'm not a Pro, but because the sink is located on the end of the vanity, I think I would leave the one large mirror over the vanity. I would remove the other mirrors at the end of the vanity and makeup area and either use chunky wooden shelves instead of the glass shelves, or use a recessed shelf unit or place art work there. I would use a single decorative mirror over the makeup area, maybe an oval or round shape.
