It looks fine. Not every wall/space has to have something on it.

Put a tall orchid arrangement in the middle.

What about paint color or wall paper?

Narrow it down with paint chips ... your floor will be tricky to complement. Once you narrow it down to a handful of colors, then order some larger Samplize samples.

Wallpaper might work, but I've been looking for the "perfect" wallpaper for a powder room for 3 years, so hopefully you are better at making a decision like that!

you could do the whole wall as a mirror and mount the sconces thru the glass

Agree^^^ or it looks like you can fit an identical 3rd mirror in the middle?

And if you can’t modify the tile base under the vanity you could paint it to match the vanity. That will help a bit.

Try adding an interesting plant (with a saucer) to fill the space….many times this bit of a natural element is all you need….obviously something that will grow vertically not a trailing plant
