Total newbie, diy inground spa?
I am completely new to the world of pools and spas. The hubby is from Alabama and bringing him up to the land of snow and cold, I'd like to make him an inground hot tub in the backyard. I'm open to any ideas for a simple diy job (though I understand these things aren't simple). I've considered fiberglass shells but they're a little too $$, livestock tanks, but I'm not sure they won't crack when buried in the freeze/thaw cycle. I'm recently thinking about pond/pool vinyl liner? Really we only need/want this thing to be quite small, maybe four people in it at the very most. We need it to have a filtering system and preferably some sort of heating/jet system. Realistically our budget is 1,000 or under but we are prepared to do ALL the work ourselves...we just need some experienced direction!
I am looking for any leads, links or ideas whatsoever, I really appreciate it!
