I need to see the counter since that floor is pretty busy .IMO new lighting first I like a full wall of mirror with 2 sinks so I would leave that . As for vessel sinks they are really a personal choice if they are big enough they work as for faucets you will need to be very careful since the ones you have are very close to the wall so the vessel sinks are going to have to be too small IMO Do nice undermount square sinks and then just new faucets in a style and color you like

Can I use vessel faucets with undermount sinks?

The only place I would use a vessel sink is in a powder room. They're just not practical in a master bath. It sounds like you like the look of the type of faucet that is usually used with vessel sinks. There are dozens of different faucets available. It's hard to believe you wouldn't be able to find something you like that is appropriate for use with an undermount sink. Also, is your existing vanity standard height, or is it a lower height that was popular decades ago? If it's shorter than current size, unless the users are short and like that height, think about replacing the vanity as well since you're reworking everything else on that wall. I also like separate mirrors so you can have sconces on either side. The light from overhead fixtures is just not as good.

Here are pictures of bathrooms where they used wall-mounted faucets with undermount sinks. I wonder how much splashing that would create. The second picture looks more practical. Maybe someone who has this type of arrangement can comment.

If you mean wall-mounted faucets, remember they will be built in to the wall and so the plumbing is not accessible the way it is in a surface mount faucet.

I have a wall mounted faucet in my master bathroom vanity, and I love the look and the easy cleaning. However, we've recently had some trouble with our faucet and have no way to change them without removing the backsplash. We're coping with what we have, but I would avoid the wall mount for the reason Andee mentioned.

"NO to vessel sinks. Splash zones!"

I used to believe that until I had them. And I'm quite the splasher.
