Yes, a swim spa can be used in winter! One major perk of having a swim spa in New England is the top-notch insulation, which lets you use it all year round. In contrast, traditional pools have a more limited season of use. Plus, heating a regular swimming pool can really add up, but the cost to keep a swim spa warm is a lot more budget-friendly over time. So, if you’re looking for extended comfort and relaxation without the high heating costs, a swim spa is the way to go.
