The kitchen base cabinet i want to install is 34 1/2"'s in height. The post form counter top is 3/4" thick. Together that is 35 1/4". I am dealing with a very level floor no shims needed. Everyone tells me a finished height with base cabinet and post form counter top should set me right at 36"? Or to get a finished height of 36" do i need to pack out with 3/4 strips on the top of the base cabinet then install the counter top. If that is the case why not make base cabinets out of the box at a height of 35 1/4"?
