A swim spa is a type of hybrid aquatic equipment that combines elements of a traditional swimming pool and a hot tub (or spa). It's designed to provide users with a space for both swimming and relaxation.

The primary feature of a swim spa is its ability to generate a current for users to swim against. This current is often adjustable, allowing swimmers to control the intensity of their workout.

In addition to the swim area, swim spas typically have a section with hydrotherapy jets similar to those found in hot tubs. This allows users to enjoy a relaxing soak after a swim or to use the spa independently for therapeutic purposes.
