Almost 5 years ago, I was cleaning the hall bathroom and noticed the white shower curtain bar was not too white anymore. It was chipped and had rust spots it. I wanted to get a new one but chose to just refresh that old one with some spray paint until I could go shopping,
Surprisingly, that quick paint job is still holding up and matches my new toile shower curtain just fine.
My advice - if you get a new shower curtain, iron it before you attach it to the shower liner with 12 rings and ribbon ties, just saying!
I take most all my photos with an iPad and the lighting makes the colors look different. The curtain is black and cream toile, the wall paint is pale yellow.
