Excellent Inflatable Hot Tub Insulation

With $50 of 1/2″ thick sheet insulation from Home Depot and about 2 hours work, I insulated my inflatable hot tub better than a purchased insulating blanket cover! It insulates as well, saves about 20% on electricity (paying for itself in 2 months), it’s easier to get into the hot tub with no blanket to remove, and this insulation will last much longer than the Cleverspa cover I got last year which fell apart in 6 months from the sun.
