It's a 36-inch mirror centered over a 60-inch vanity with a 19-inch sink. We are getting recessed lighting, too. My question is whether the style of sconces works with the style of faucet. I picked the faucet when I still thought I was getting a medicine cabinet. Our vanity will look similar to this one, but without the tower.

Here's a sketch somewhat to scale that my 11 year old did. Ceiling height is about 8 feet. The right side of vanity is against a wall with a window next to it.

Just post jpegs of the faucet, the tile and the lights. Then we don't have to dig in your text for the "issue" .........?

Can you put two sconces - one on either side of the mirror? If so, I would choose a different type of sconce so you have improved lighting for makeup, hair, etc. I don’t like two lights OVER the mirror because of shadows. I understand the problem with black faucets and hard water. Too bad because it does have the “look” you want. I love the vanity idea with the rest of the choice, but please post photos and/or links to the products.
Is the floor a deep grey herringbone tile like the photo?

I see what you were trying to accomplish with this hexagon sconce shade but think that coordinating with the round mirror would be better as they will be right next to each other. That bar in the light fixture you have selected creates some imbalance as it is not centered on the back plate which is distracting. I think a simple round sconce or simple shape would be less complicated and a cleaner look. The one on the bottom has a marble shade which could be interesting with your counter. Also because you have a wood vanity, with black handles and you will be bringing in black light fixtures and mirrors, it will tie together enough that having a chrome faucet won't be an issue.

Thank you, everyone, for your input.
