My 2c: The med cab with the same width as the vanity will look ok. (Had the same in my old bath though the vanity was smaller -- and it looked fine. Replaced it with a long mirror spanning over toilet + vanity and that looks great too). IMO a recessed one would look better -- but it does not matter really. Regarding the light placement, no matter what you choose, arrange the lights aligned/centered over the sinks and make sure that they do not look like one long line of lights. If they are two separate lights, then they should look separate or else there should be one giant (5-light?) strip centered around the entire mirror. Hope this helps..

When I was researching this topic, I read that top lights created unwanted shadows on your face so side lights were preferable. I have a bathroom w/ top lights and one with side lights and don’t see much of a difference. I placed them the way I did b/c of spacing, no other reason. I also have magnifying lighted makeup mirror on the vanity counter.

m down to the wire, in decision making, before electrician comes in to review our electrical needs in basement. I so want sconces as opposed to overhead lighting, but it may be as simple as just throwing in the towel on this one. Placement of mirror(s) and lighting over the sink (left side) and the makeup side (right side of vanity) has been extremely difficult for me due to the odd angle of the vanity and the two walls the vanity spans on are not same width. I would appreciate any advise.

You might see the reflections from the mirror of the back of your lights.
