I just ordered 2 of these mirrors for my upcoming bath remodel. It is available in 4 different finishes

I think it would look great with your vanity. My daughter has the same mirror in one of her bathrooms and it is very nice quality. It is the Colby mirror from Crate and Barrel. If you sign up for their emails they will send you a code for 15% off. https://www.crateandbarrel.com/colby-nickel-wall-mirror/s244034

Are you planning on lights on each side of the mirror or one above the mirror. I am using these sconces with that mirror

There are so many options for lighting but I think your vanity lends itself to a contemporary style. If you put contemporary bath light in the search box on any lighting website you will come up with tons of possibilities.

Thank you. Love both of these!
