We're building a new house and I'm having trouble with some decisions in the master bathroom. Along one wall we have a freestanding tub in the middle with 2 vanities on either side. One is 5' long, the other (mine) is 7' long. Sink will be centered on both vanities. There is a window over the tub.

We were hoping to do framed wall mirrors for the vanities, but I'm not sure what size to get that will work for a 7' vanity. Any suggestions? And I'm at a complete loss for lighting. Do I get a 4 light bar for both sides? Would that provide enough light? Thanks!
