The only appliance we paneled is the DW. With the panel, it looks identical to the trash cab on the other side of the sink cab. Both doors have the same handle/pull as all the other doors/drawers, but for those two doors (and the over the fridge cab) we used the 12" size pull (8" on almost all the rest). The fridge and the stove; KA built-in and Wolf range, are not paneled, and have their own factory-installed handles. IMHO, they all look fine together.

I don't think getting satin nickel hardware will take away from the appliance handles; I think it'll tie everything together, actually. I don't think you necessarily need to match your hardware with your appliance handles - find something you love that fits the overall look of your kitchen. That being said, I DO like the European pulls, and one of the reasons I went with them was that they look good with the handles on my Jenn-Air DW and icemaker and Thermador fridge. The pic is a little distorted, so the pulls look a little twisted when they're not:

You definitely do not need to match your kitchen faucet to your appliances. The majority of people opt for stainless steel appliances, but have faucet finishes of all kinds. Whether a brass or brushed nickel faucet will go in your kitchen is dependent on your choices for cabinet color, counters, floor, light fixtures—which you have not described. It’s nice to have your faucet finish match your pulls/knobs, but not required, and many kitchens do not have them matching.

Hello! I am not sure if you have found a solution yet, but I would check out Waterstone. They offer a satin brass finish, but their classic bronze might also be a solution. Here is a link to their website We hope you find the perfect fit!
