Do you like this? Can buy w matching mirror …
This is almost exactly the look I think you're going for - even with a light gray vanity and window in shower. Half wall yes, and the vanity that bumps right up against the half wall - that gives you the ability to do a wider vanity. Looks like they only have single sink so the vanity configuration would be different but size looks close. Note the shampoo nook is on the shower head wall - probably don't want that but this shows you what that looks like.

nook with accent tile
half wall with glass on top
Nook placement in half wall
Note where hand towel hooks are - balanced on both sides. I would do that or one of the ones that sits on counter in between sinks where that vase is.
