We ordered this June 2020 and were told 6 months, then received early in October by surprise! Best purchase we've made since moving up to 9000 feet in the Rockies! We absolutely love it! Had a 12' x 12' concrete pad (approx. 6" deep) poured and then built our deck around it (still not finished with the deck). Probably missed only 10 nights in this hot tub in the past year - it is our evening relaxation. Can't recommend highly enough! I recommend "SpaGuard Complete" liquid to add with Bromine, etc. to balance & clean - it really works well (rather expensive, but works so much better than other spa solutions we've tried.
