This is exactly what I am planning on doing. I modified the L-shaped Kegger plan (dimensions as well as putting the fridge in inside corner). So far, I have the framing done, the counters on, and I JUST finished the keg box (I’m giving it a test run without the door even started – already down to 39F after 30 minutes with just a scrap piece of 1.5″ insulation as a makeshift door). I am pleasantly suprised how efficient it is.
For mine, I kept the door behind the bar or “inside” of the U. There is plenty of room. I’m sure you could put the door on the outside, but I’m not sure how it would look… it all comes down to your skill at finishing everything well and personal preference at that point
Good Luck!
