Energy Efficient Michael Phelps Signature Series Swim Spas by Master Spas

Not only does every Michael Phelps Signature Swim Spa by Master Spas use an ultra-energy-efficient motor to drive the Wave Propulsion™ System and create the best possible swim experience, but we build our swim spas to be used year-round in every possible climate. In fact, environmentally friendly Icynene foam insulation makes a Michael Phelps Signature Swim Spa by Master Spas the most energy efficient swim spas in the industry. Every swim spa is built to not only meet but to exceed the stringent California Energy Commission (CEC) efficiency standards. All resulting in what really matters — a superior swim spa experience and savings for you and your monthly utility bill.

A Michael Phelps Signature Series Swim Spa stays warm despite the open winter air with a variety of insulation features.

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 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.
