Listen to your favorite music while enjoying your swim spa with the Fusion Air Sound System, an available option for any Michael Phelps Signature Swim Spa model. This system includes four interior, water-resistant speakers and a subwoofer to maximize the sound quality. The Fusion Air Sound System connects quickly and easily to your devices via Bluetooth, allowing you to stream your favorite station or playlist. You can even connect to your tablet, while using a waterproof case and mount, to stream your favorite movie or show — turning your swim spa into a "cinematic" experience.

Water Management System

The Mast3rPur™ Water Management System is a synergistic blend of three proven natural water sanitizers that, when combined, creates a chemical reaction known as Advanced Oxidation Process. This results in clean, clear, fresh-smelling and silkier water. The Mast3rPur™ option comes equipped with the QuietFlo Water Care System, a 24-hour circulation pump.

Swim Spa Covers

Master Spas covers lock in heat and save you money. Safety, protection, and energy efficiency are all key components of the exclusive Master Spas Covers. We only manufacture covers that are built to the strict ASTM-F1346 standard for lockable safety covers. Not only do we build our swim spa covers to this strict standard, but we prove it by certifying them through UL. Constructed using top grade marine vinyl with UV protection and high density 5” – 3” tapered foam, these covers lock heat in and last a long time, and that saves you money.
