I've never used them directly but the owner did, they provided glass & mirrors for cabinets: Capitol Glass. If I remember they are on Washington. More uptown is Broadway Glass and Mirror, I used them a couple of years ago when I needed mirrors for a couple of rooms and glass for cabinet doors. On BW and 84th or 85th. Get specific directions.

I love the mirror, it's beautiful, but I don't care for it there. What bothers me is the frame around it and the way it extends out. It doesn't seem to fit properly because the frame does not go past the end of the sink. Personally, in a small bath I prefer the look of twin mirrors. I think in your space because the vanity is small and the bowl comes so close to the wall on the left, oval mirrors would look better. They would cover the space you need them to without swallowing up the vanity area.

Get the frame built, call a glass place and they will TEMPLATE , fabricate, and install the mirror. Frame first, do not try to do it backwards.

Those chairs or similar are *everywhere*. I’ve seen them at world market without the cane cushion.
