I did these for Mama's Kitchen, right down the street, in Fort Lauderdale.
The customer knew what he wanted design details wise.
They just "rest on" the counter, and are not tippy.
Panel itself is 3/8" material, thicker than is commonly used.
The other dimensions are 36"x36", more than adequate to
satisfy the health inspector. It even has a little return, that extends
toward floor on the bottom.
