As far as I am concerned...
if it can't open, it doesn't deserve knobs/pulls.

Besides, why have guests tugging on something they can't open?

I agree, doesn't open = no knob/pull. After you live with it you can always add one later.

I like the look of consistency, so I would add the knobs.

Thanks for the replies. Your reasons were our reasons for and against the knobs/pulls. So, I guess it can go either way. I just wanted to see if there was a standard way of doing it.

For our bathroom vanities, we didn't have this piece of slab, just full size doors. I like the look better. For the kitchen we did put a long pull under our prep kitchen so that I can hang a towel there.

I would put pulls below the sink. I think you'll find it might look like something is missing, or...maybe not. It's probably personal preference. My cabs are full size doors like pps7, but I don't think I've seen the drawer above without hardware.

pps7 can you tell me what kind/brand of hardware you have? I'm going nuts trying to pick out hardware. I have espresso cabs too. Do you have any closer pics? Looooovvve your bathroom!!
