Dimmer: a switch or dial designed to raise or lower the brightness of a light fixture.
There are many different styles, and you can even find murals that fit around the light fixture on your ceiling.
Before I knew it, I was tearing out walls, researching vintage wallpapers, and scouring eBay for just the right hardware and light fixture.
I chose to hide the worst of the damage to my ceiling by installing a large light fixture in place of the damaged panels.
When using a different light fixture style in your bathroom keep continuity by using the same kind of finish.
