The cost of a swim spa depends heavily on a variety of factors, including but not limited to brand, model, age, features, and location. On average, a good-to-high-quality swim spa model will start at about $20,000 and can reach $40,000 or more. Please keep in mind that with a swim spa, similar to other large investments in your home and lifestyle, you will always get what you pay for. While it may seem tempting to opt for a model that saves you a couple of thousand dollars, this decision could cost you down the road in repairs, maintenance, or having to purchase a new model entirely. Before purchasing a swim spa, we always recommend that you first do your research. Consider the different brands available to you, warranty options, available models, or even opting for a used swim spa from a reputable brand.
