Why is your wall tile installed before the counter tops?

Yes oval mirrors would look very nice in the space, go for the kind that tilt mount.

Use the exact same lights on all fixtures.

We are on bathroom remodel number four and that is how they have all been done. Countertop and tile guy work together and know exactly how much room to leave. Have actually had two separate tile guys over the years and they have both done it this way.

First match the finish on the hardware of the vanity, not ORB. I don't think you want dark sconces and a dark mirror frame in this area. Here is my first suggestion for the mirrors and sconces.

I love that look for the sconces but have been unable to find any other than candelabra bulb type and we are really concerned about the light output.

I should add that the tile in the photos looks grey and white but it is actually Bianco Orion tile and has a great deal of brown tones as well.

I have seen many sconces that match with single, double, and triple lights--same style, just single or multiple bulbs with a double (or triple) branch. Looking at your electrical box placements, though, for both vanities, it looks like you could use the same mirror for consistency but use up the extra wall space on the larger vanity by installing coordinating lighting with double-branch or wider sconces. I assume the larger vanity is for a person applying makeup and styling hair, so it would be nice to have extra lighting.

I'm NOT a designer, so perhaps I'm off-base. You mentioned oil-rubbed bronze faucet/fixtures, yet I see brushed stainless cabinet hardware. Those look new. Will the mirrors have a metal frame or any metal hardware--what finish? Keep that in mind when selecting your mirror's and lighting's metal finish(es)--ORB or brushed stainless?

Restoration Hardware offers a lot of single and double sconces in multiple finishes. Some look the same but are wider or more narrow, which might work for your bathroom. This style may be not what you like/look right, but here are examples:

RH Wide Sconce

RH Narrow Union Filament Sconce in Bronze (there is also a narrow "tall" version)

They have many more traditional, industrial, or contemporary choices in various bulb configurations that match.

I would, perhaps, consider sticking to brushed silver-toned faucets/towel rings since you have that on the hardware, already, and it would be easier finding a mirror to match. But, I know it's common to mix metals, so you should do what you like. (I'm doing all chrome in my Master Bath and chrome fixtures with aged brass lights and brass-colored cabinet hardware in my hall/kids' bath that has a navy vanity.) Good luck with your project--looks nice!

Thank you so much. I appreciate the suggestions. The cabinet hardware is being changed to ORB. All faucets are ORB as well. Thus, why I am planning ORB lighting. I like the lighting suggestions of the single vs. double matching lighting. I had actually been considering that and thought that might be a possible solution. I will check out Restoration Hardware.

The wider the sconce, the more narrow the mirror
