I went to Walmart the other day to try and pick up the fridge but even though it was supposedly in stock it wasn't. I took that as a sign and on the way out I saw this large 38 gallon PP (29"Lx17"Wx18"H) bin/tote & lid for $10. Just perfect for two of my 7.9g fermenters.
I have some 1.75" hard foam paneling and silver bubble-wrap stuff. I wrapped it up with two layers and put a piece of the the styrofoam underneath. Until I can resolve a dedicated Cold Chamber ( I want my guest bathroom back!) this oughta work for ales for the time being.
Every 12 hours or so I just swap an ice-pack out.
Those buckets are pretty big- maybe it would accommodate carboys. Hope this helps.
