I would do matched mirrors centered over the sink of each. The extra counter is just that -- if you really want, you could put a third mirror over the long vanity, but I don't think you'd miss it.

Was thinking what ACM said. Ditto.

Show the bathroom plan, with the vanities and all else including tub.

The flat on paper , 2 dimensional plan with all the actual inches. Of everything.

I need to see the space so a pic of that wall and some clue as to your style . Post the floor plan and the pics here in comments DO NOT start another post.

Hi, it would help everyone here to see a picture of the space, and drawings. It's the best way to get the best possible advice on this website. So please post as much as you can, there can never be too much information.
