36-37 degrees.
I didn't insulate the floor, (tile, on concrete, on fill dirt) which I suspect would help a LOT, but then, I only use it 10-15 days per year. Anything below 40 works fine for a cooler.
Construction is standard stud wall with 3 1/2" fiberglass insulation, plus 4" of foam board on top of that, and inside is thin white fiberglass panels. Door was a prehung unit off a used cooler, just screwed to wood opening.
