Hi All, new here.
I did buy the Costco Infinity 3 person spa, delivered here in the VA mountains for $2000! I was half pleased, half disappointed when I got it, no insulation, dorky plastic sheet bottom, non treated wood. And the don't expose to sun notice was disheartening.
But the only spa I had before was one I built out of 4x4"s and lined with epoxy and used a 115v home water heater for! I did use that one for ten years or so, it was all I had and was wonderful.
But, I stuffed $30 of fiberglass in this new one, sprayed wood preservative over the bottom lumber, put on a plywood bottom, glued 4" of solid foam to that, flipped it over, filled it, and am enjoying it.
Price was fantastic, we'll see how long it lasts. Haven't received the hard cover yet ("it's on the way") but I'd say a pretty good deal with the ozonator and hard cover. It has a Balboa VS501 series controller/heater.
Mike
