I purchased this light fixture from schoolhouse.com. The first picture is their Norfolk sconce: a ceramic fixture that is pressed, cut and glazed by hand in Portland USA. Check out their website❣️I purchased several of their handmade light fixtures. They are simple and well made. You may find another light fixture that is more to your liking.

Not sure what your other lighting is but based on the the paint finish on the mirror and other colors when with a farmhouse/rustic look. If you have something different in mind, some pictures if the lights and rest of the bathroom would help in giving better feedback.

Hope this helps.
