I have a styrofoam filled hot tub I bought for $100. I had to put $3000 in to in parts and fixed several leaks. It’s not unrepairable, just not as straight forward. It was easy to find some of the leaks because the spray foam would be saturated with water so I just pulled out the wet foam and followed it to the leak. And when I was done I just put in some of the pink fiberglass insulation in it’s place, but even that isn’t necessary.
