Our spa/hot tub is in need of a new cover due to damage from a tree-limb that fell during a storm. The existing cover is the original that came with the spa 3 years ago. It was fine but in addition to the new hole, the vinyl and seams were starting to tear, and it was starting to smell.
We are faced with spending about $300 to order the same exact thing, or more depending on upgrades to the insulation, vinyl, etc.
So I had the idea to build one using 1/4" plywood to make 2 tapered boxes that would be hinged in the middle and filled either with sheets of insulation and expanding foam, or entirely of expanding foam.
My concerns would be the total weight, and moisture. The existing one is not light, so I want the new one to be about the same weight. And for moisture, I know it will need extra protection and maintenance.
