Step 6Insulate the tub
I used scrap polystyrene packaging and cut it up into shapes that would fit between the bars. I toyed with using expanding foam but I reckon it's less wasteful and cheaper to do it this way.
Cut a large piece of closed cell foam to insulate the base. You could use foam camping mattresses or similar. I just happened to have a huge piece laying around.
