no, it wouldn't

I mixed finishes in all my baths..looks pretty natural. I don't even think people notice..they just see bigger picture.

Don't mix brushed nickel and polished nickel, or chrome and nickel, these are too close to mix successfuly.

ORB is different enough from brushed nickel, and also gives that very neutral feel, it being dark..you should be fine.

but you can also cross post your question in Home Decorating forum..there's usually where questions about colors etc. go. Or Bathrooms one..but Home Decorating has more traffic..you 'll get more responces

Thank you! I'm fairly new to Houzz (at least to posting!) so will have to figure out how to cross post! :-)

you just copy this post. and paste it in the other forum:)

Our last apartment had mixed metals in the bathroom. They worked well. As long as the towel bar(s) and hook(s) match, while the plumbing fixtures match, it looks cohesive. I also think style is a bigger factor than color.

We generally suggest avoiding mixing finishes, but it depends on the space. Pictures would make the question easier to answer. Also this article has a good explainer about mixing finishes: bath lighting
