Welcome to our forum.
This is a great tub and it is not just some 800 number, they are just another branch of Clearwater and are very anxious to keep you happy. Regular spa companies hate them because they are dealing with Costco. Also, they use Balboa controls and pumps and they are not proprietary so any good repairman can get them in the future.
One of the main reasons it's less is you're buying direct. Costco doesn't inventory or handle the tub at all, it is shipped direct from the manufacturer to the end of my driveway. I was hoping to hear from someone that actually owns one, not just speculation.
That Belize thing? That's not the same tub. The specs say it can be 120v!
Clearwater's quality has gone down hill significantly over the last couple of years. Like really bad.
