Love the vanity lights. 
We bought a house and did updates. 1 of the updates was replacing the master bath mirror with 1 large vanity mirror and lights. This looks so great against the white paintgives a great contrast and really modernizes the space.  I also bought the vanity mirror from Wayfair as well (I think Hertz Mirror). They both go so well together!!!!  Our vanity is 81 inches long the mirror ordered is 77 inches long and it fits perfectly, the vanity light is standard size for 5 lights and it goes well together
