Could you post a picture? Are there sconces? It's hard to say without pictures, although I am actually a fan of what Clair is saying, full length and full height mirror with the sconces mounted through the mirror.

Here is a picture, sorry I can't rotate it. I was planning on sconces...open for any suggestions. Thanks!

Here's what you've got. If you do a pair of side sconces over each sink you will need at least six inches to do a relatively narrow sconce at the corner, so then you will need six inches from the other edge of each sink cabinet to balance the sconces.

(Unless you do a very narrow linear sconce (I am using 1" LED strips in each corner of mine, for example)

Pairs of sconces in a six inch area is represented in red.

That leaves the green rectangle as maximum space for mirror over each sink which is 24" in width maximum.

If you did a sconce at each corner and single in the dead center you'd still have to keep the mirrors around 24 max width for symmetry. (blue)

If you did a full mirror with sconces mounted through them you would have slightly more flexibility.

If you do an overhead sconce over each sink, you could go almost the full width of the sink base for each mirror.

There is one very important consideration here, though. Where are the Outlets and Switches and what, how high is your backsplash?

Wow! Thanks so much for your help...the visual is great. We are at the early stage of construction so haven't tackled outlets and backsplash yet...I started with light fixtures and mirrors before the electrician comes. Truly open to any suggestions. If I were to do a full framed mirror, what would you suggest regarding sconces? Also do you think a linen tower would help? Thanks again

Save yourself a lot of headaches and plan the outlets and the backsplash height (roughly), now. Put outlets either in the side walls or in the black area shown but do not put anything up higher. Often we see outlets and switches placed where they interfere with mirror sizes or mirror placement. Don't put anything in the blue area. Avoid that by thinking of it now.

since you're using 2020 have completed the plan of the entire bathroom? I would say yes in using a linen tower but how big is your bath is going to be?

The bathroom is 12.1x14.4, roughly 174 square feet. Thanks!

Would you recommend either of these options? Many thanks!

I am a big fan of the first look you show.

Greatly appreciate your help. One more questions, if I were to move the 15 inch cabinets to the exterior to allow for 2 framed mirrors with sconces, what size mirrors and what spacing of the sconces would you recommend? Thanks!
