Have small counter top of 3/4" granite. Want to attach from underneath

into from below.

Q: Is that sane and does it work?

Don't bother. Silicone will hold it in place just fine. Just make
sure all of your cabinets are level.

If you have a dishwasher get the brackets to side-mount it into the
cabinets.
