I just completed my bathroom remodel and struggled to find light fixtures, mirrors, cabinet hardware, and shower glass hinges that were a close match for Delta Champagne Bronze finish. Houzz was a great resource during my hunt, so I thought I would share my finds! These all worked...

Keep in mind, the distance from a light source makes the exact same Delta finish look different, so don't stress out that other accessories don't match exactly. It's really not noticeable.

Also, I mixed and matched the Delta Tetra faucets with the Trinsic towel holders...I loved the Tetra faucets but preferred the lower profile Trinsic towel bars and hooks. I was worried it wouldn't look cohesive, but that's not the case. The Champagne Bronze finish was tricky to work with, but I love the look of the finished project and have no regrets!
