Depending on their design and size, home swim spas can come with either one volume or two volumes of water. Models that have counter currents in one volume of water are designed to make it easier to move from one end to the other without getting out of the spa. This type of spa is ideal for relaxing, but if you want to swim and relax at the same this might not be possible, unless of course you find swimming in hot water enjoyable. It's all up to personal preference after all. If you're going to use your spa mainly for swimming and exercise, then I would recommend the two volume model which is larger than the one volume spa. It features a counter current swimming pool and a spa in a single unit. The two have separate heating and filtration, which means you can easily adjust the temperature of the pool to a pleasant and enjoyable level, that is not overly hot, and have the spa area set to a lot more warmer and relaxing temperature.
Despite the differences in design, both models are made to deliver the amazing benefits of hydrotherapy. So, with a simple step like installing one of these in your home you can begin your journey to becoming the healthier and happier version of yourself.
