Swim spas and training / exercise pools have to be considered carefully, you shouldn't simply buy one online because you need to discuss the features and usage with an experienced supplier and someone that understands exercise and swimming, as well as the spas themselves. For swim spas with more powerful swim currents for fitness training, a larger swim area and either with an included hot tub massage area or separate hot tub area, we can advise on the best model for your use. Water care is something most people want to be as automatic as possible. Budget models require some manual chemical maintenance of a few minutes a week, whereas higher specification models can have automatic salt systems taking care of sanitation of the water and UV systems removing organics and cosmetic products from the water.
