I need to add some storage in my shop that used to be the 2 car garage. There is plenty of room along the upper wall on the workbench side so am thinking of adding cabinets. Am wanting to build some laundry room and eventually kitchen cabinets anyway so figure this will be good practice. Most of the kitchen cabinets I see seem to be 12" in depth, so as not to hinder counter space. Just to make sure there isnt something I am missing here, does it really make any difference how deep upper shop cabinets are? Seems like a waste to just make them 12" deep for storage. Those who make your own shop cabinets....how deep do you make them? Thanks in advance for any answers or advice.
