I can't suggest any, but did you also post this on the bathroom forum? Someone there might have ideas for you.

I have and Jack and Jill and love it. We have one long vanity and one sink. My kids were teenagers when we built our house. One boy, one girl. They were NEVER in the bathroom at the same time. A single sink in a long vanity was never a problem. I think they enjoyed the counter and drawer space more than a sink they only used for a few minutes. You won't regret your J&J. Now our guests love it! Very private for them.

That looks like a really terrible location for lighting given the light-blocking frame around the mirror. I would replace it with a small, better-looking fixture, and get an electrician to run power to each side of the mirror so you can have sconces that are set off from the wall and give you decent side lighting.

Thanks for the help here! Right now, was planning on SW Repose Gray for the master bedroom, but open to updating. There will be a walk through closet that leads to the bathroom so I'm fine if the closet & bathroom are a different paint color. The tile for the rest of the bathroom floor will be this Happy Floors Kursaal slate-looking tile, and the teak vanity will be right outside of the walk-in shower. I'm likely leaning towards light gray or blue for the bathroom - potentially continuing SW Repose Gray, BM Gray Owl (recommended above), BM Solitude, BM Mineral Ice. Alternatively, I could embrace the bright white and going with SW HIgh Reflective White... but I just feel like throwing another shade white in the mix could be tough to navigate. Appreciate folks helping me think through this...
