I've found that in the tropics i didn't mind sacrificing fridge space for more efficient insulation
(small spaces are easier to cool anyway, so the smaller you can manage with the better as far as energy consumption
is concerned). To that end, i installed my extra insulation
on the inside of the compartment (and on the lid as well), about 4 inches of it (solid extruded polystyrene sheets) and then did the inside surface in formica. Id i did it again i'd lay up some thin sheets
of glass instead, but the formica works. Stick it on with some cheap
household silicone sealant
and Bob's your uncle. No removal
of countertops necessary and if you want to you can do it in stages. Only tricky bit is taking the cooling
plate out and re-installing it when you're done (making sure you don't make the compartment so small that it will no longer fit!).
