Haven't had an opportunity to fill and test the hot tub itself as the cover is still missing. After 2 months of waiting and two delivery attempts, I would say that if you can avoid ordering a large item from WayFair, I would. It seems they try to do the same type of assembly line, automated system type delivery for something as large as a hottub the same way they would ship a pillow. I'm super nervous about the condition of the hottub as 3 folks on a sliding piece of plastic slid and plopped it onto the patio. I could hear things shifting within as they did.
