A self-contained unit offering both the benefits of a swimming pool and a spa, it provides a space for aquatic exercise and relaxation in a compact form factor. These units typically incorporate a current-generating system, allowing users to swim against a resistance flow, simulating the experience of swimming laps in a much larger pool. Jet systems are also usually integrated for hydrotherapy and massage.
The appeal of these aquatic systems lies in their versatility and space-saving design. They permit year-round aquatic fitness regardless of weather conditions. Moreover, the integrated spa features offer therapeutic benefits for muscle recovery and relaxation. Historically, their development addressed the limitations of conventional pools, offering a practical solution for those with limited space or a desire for a multi-functional aquatic environment.
