Granite tower help please

[JONNYROTTEN]

Sending out my template to granite shop.I need to know what size hole to drill for tower?Im going to slide a pvc tube through fridge hole,through granite into tower to fill the void between fridge and granite.Im thinking the bigger the better to let more air flow up tower?Is there a standard setback from counter edge to tower,or just whatever feels comfortable?

Most commercially available tower columns use 3 or 4" diameter tubing. As long as yours has a mounting flange you can make s hole of matching diameter.

Cheers!

[Edit] Set-back is pretty much user preference...
