Honestly, why does it matter? Are you happy with your choice? If so, that's all that matters.

They don't have to match, but they should complement one another to be aesthetically pleasing, if that's your goal.

@AtomicJay007 - thanks. I haven't made my final choice yet, only in that the style is a plain round knob due to hand pain. The square knobs look modern, but they hurt my hands. Both come in chrome or brushed satin nickel. I don't really have anything to compare it to, since this is my first reno. Appreciate your feedback.

I know it's like heresy to say this around here, but I'm going to anyway: comfort rules over everything else! Fully agree with your decision to go with round. If you want to keep the look modern, there are quite a few round knobs that can maintain that look for you. You could also look at some round glass knobs that might compliment everything nicely and not have to worry about coordinating the finishes. Something like:

And if you care to post pictures of the faucet, vanity and knobs you are considering, there are tons of talented folks who can give you some feedback. You'll get more interest and better advice if you show everyone what you're working with. Good luck!

@monicakm_gw - I love your husband's responses ...lol. Thanks for the advice.

@AtomicJay007 - the knobs are included in the price of my bathroom vanity, which is white, shaker style, maple. Here are the two choices. There are other choices, but again, not comfy. I didn't think to include the picture earlier. Just plain round, but in chrome or bsn. I think I'm going to go with bsn so that not everything is chrome. My bathroom is quite small and rectangular.

I love the glass knobs! They're absolutely gorgeous!! Thanks for the picture. Did you get it from the Internet? I may look for knobs like those later on if I feel the round knobs are too plain.

I think the brushed nickel will look great!

Also, as you may have already seen, not all brushed nickel is create equal. I've seen some that is darker with more of a yellow undertone. The brushed nickel Jado faucets I have in my bathroom are a brighter, lighter shade.

@AtomicJay007 - thanks again :)

@monicakm_gw - yes, I have noticed that, thanks. Some definitely do have a yellowish tinge. I'm glad your Jado faucets have a nice shade!
