Michael Phelps Signature Swim Spas by Master Spas combine the convenience of an at-home swimming pool with legendary performance. An obstacle-free swim area and continuous water current make it so you can train at home — without losing sight of your goals. Use it as a complement to your training or centerpiece of your swimming routine.

About the Wave XP Pro Propulsion System

The Wave XP Pro Propulsion System takes advantage of Master Spas’ patented Wave Propulsion Technology. The unique propeller design does not require air to be introduced into the water to increase its strength, allowing for a more realistic swimming experience.

A variable speed motor allows you to choose your level of resistance. From zero to 100, you you can find the ideal speed for your swim or exercise session — all from the easy-to-use SwimNumber™ System.
