The short answer is yes, you can use your inflatable spa in the winter. However, if you’re leaving it set up and running, inflatable models struggle to maintain their water temperature once the outside temp drops below 40 degrees Fahrenheit. They simply aren’t built with the insulation necessary to keep up.
Compare it to using an inflatable cooler in the summer. Your popsicles and ice cream will stay cool for a while, but eventually, if you don’t eat them fast, they’ll become a puddle of goop in the bottom of the cooler. Now reverse that. If you’re using the same cooler to keep your chili hot, it’s eventually going to get cold, no matter what you do to reheat it, because the air insulation can only do so much.
So the long answer is that winter is not ideal for using inflatable hot tubs.
