You can never have too much light. I agree having a pair of sconces will be excellent for make-up/shaving, but I'd also add a pair of recessed LED spots in the ceiling centred over the sink, about 12" apart. Get the kind with a deeper housing so the light source is only visible when you are directly underneath it. The typical LED ceiling fixtures these days have the light source flush with the ceiling and would look too intrusive in an elegant room like this. Here's an example of a beautiful one. I've shown the photo below but the link shows the specifications. It comes in 3.5" and 4" sizes. Likewise in your shower (I assume there's a separate shower?) I would install two LED recessed lights to cut down on shadows. These can be the typical ones with the light at the surface.

I do love the look of a lighted mirror but I dislike how they cast light on the face. I also live with a stickler that wants to be able to change the bulbs if need be. Thank you though.

If you were to do 2 separate mirrors, will you have enough space between the wall and the mirror for a sconce without making the mirror too skinny? The RH photo has plenty of wall space on both sides to mount the sconces so they could afford to have a nice width to the mirrors, width of the mirrors is almost the width of the sink bases. Note how the sconces are mounted outside of the vanity space whereas your drawing has a wall with not much space to the sink. The wall mounting plate is at least 3-4 inches that would cut into the width of the mirror on that side and to make the mirror symmetrical, you will need to trim the mirror on the other side too to have the mirror kind of center on the sink base. The mirror might end up pretty skinny and won't have the look in this RH photo like this mock up below. These mirrors are centered on the sink base but are really skinny. I have the same dilemma. My vanity is 72 inches with similar configuration as that RH photo, 2 sinks and drawers in the middle. don't have space between the wall and the sink so I did these mockups to see how the mirrors would look if I were to trim only one side of the mirror to retain as much width as I can. You can see that the mirrors are not centered to the sinks at all. I wanted to maximize my small space also so I explored the option of hanging pendants with one large mirror, like this below. I have another thread asking for advice but haven't gotten a response. I'll be watching your thread to see what others think. Let me know what you think. Edited to add: If you are ok with sconces mounted through the mirror then one large mirror is a good option to maximize your space. I think you might have space between the wall and the sink on one side and there's plenty of space on the other side where the toilet is if you were to do one mirror. Good luck!

Okay, so I'm not a professional or anything, so keep that in mind, in case I make an idiot of myself, lol. What do you think of matching framed mirrors over the sinks, and then a second set of matching framed mirrors (different than the first set, but coordinating with them) for the makeup area? The pattern along the wall, from left to right, would be A-B-B-A. My first thought would be visually heavier mirrors for "A," and visually lighter/softer mirrors for "B." I'd keep the light fixtures all the same, for continuity, either by using pendants or (like you mentioned) 3-lights on the short walls and 5- or 7-lights on the long wall, from the same line. Am I crazy??? lol Edited to add: So, I'm lying there, nursing the baby, and this voice inside (that sounds a lot like my husband) is telling me that my idea here is totally Classic ODD -- Unnecessarily complicating things. :-/ I think I'd pick 4 identical mirrors, and place 4 identical 3-light fixtures over them. Do you think you'd have weird strips of wall between some mirrors, with that arrangement?
