A swim spa blends the features of a swimming pool and a hot tub into one versatile unit. It’s bigger than a typical hot tub but smaller than a standard pool, offering a space where you can swim against a current and also kick back and relax. Designed with insulation, it’s energy-efficient and well-suited for New England’s varying weather. Since it holds less water, it’s also easier to maintain than a full-sized pool. And because it’s not a permanent addition to your home, it usually won’t affect your property taxes, although this can vary by town.
