Master Crafted

More than a standout swim spa

Master Spas takes a customer-focused approach to design and innovation, creating an unmatched swim spa experience.

Performance, enhanced therapy, and high-tech advancements in insulation, filtration, and heating systems distinguish Michael Phelps Signature Swim Spas by Master Spas among others in the industry.

Innovative design

Michael Phelps Signature Swim Spas are master-crafted so you can enjoy a swim spa that's easy to maintain and even easier to enjoy.

  • Higher efficiency, lower energy costs. Environmentally friendly foam insulation makes a Michael Phelps Signature Swim Spa by Master Spas one of the most energy-efficient swim spas in the industry. Models meet — and exceed — stringent energy standards.
  • Keep heat in and the elements out. The bottom is finished with a high-density polymer base, protecting the construction of the spa.
  • Consistent water flow, at just the right pressure. Our manifold plumbing system ensures that pressure is distributed equally among the swim spa's jets.
  • Crystal clear water without the harsh chemical smell associated with other systems. Clean and refreshing water, every time. An advanced Ozone system kills pathogens and microorganisms, destroys organic materials, and oxidizes non-organic contaminants.

Energy efficiency

Master Spas builds every Michael Phelps Signature Swim Spa to be energy efficient and environmentally friendly so that it can be used year-round, in every climate. The propulsion system is driven by an ultra-efficient motor, and environmentally friendly full foam insulation keeps your monthly energy costs low. Every swim spa is built to not only meet but to exceed the most stringent efficiency standards. All resulting in what really matters — a superior swim spa experience and savings for you and your monthly utility bill.

Advantages of full foam insulation

  • Prevents heat loss
  • Retains its shape and efficiency for the life of the product
  • Resists mold and mildew
  • Reduces the noise of your spa
  • Produces no ozone harming off-gas and is environmentally safe

Easy to maintain

You want to spend your time enjoying your spa, not worrying about water care. Master Spas' EcoPur® Charge filtration system makes maintaining your swim spa's water easier.

EcoPur® Charge Master Core Technology

Using the same multi-stage filtration techniques as Mother Nature, EcoPur Charge® relies on a unique blend of copper and zinc to create an electro-chemical reaction that eliminates many micro-organisms and removes heavy metals. Best of all, it is designed so your spa can be ready to use at any time, with minimal water maintenance, so you can relax.

Using EcoPur® Charge swim spa filtration reduces the amount of chemicals needed, saving you money each month. It also safeguards your investment by protecting the swim spa's plumbing and equipment against the corrosive effects of chlorine.

Clean, clear water — naturally

The EcoPur® Charge is made with a patented filtration fabric. With this design, the fabric is wound tightly into a nautilus master core, creating a catalytic cell. The nautilus fabric cell is encased by a unique “spring core” that allows for maximum water flow and water “charging.” As the swim spa water comes in contact with the EcoPur® Charge master core, a chemical reaction causes zinc and copper hydroxides to form in controlled amounts. Like Mother Nature, when controlled releases of copper and zinc oxides are carried into the filtered swim spa water, they kill bacteria and create a hostile environment for algae and fungal growth.

Every Michael Phelps Signature Swim Spa by Master Spas also features an advanced Ozone system that kills pathogens and microorganisms; destroys organic materials; and oxidizes non-organic contaminants to keep your water clean and refreshing every time you use your swim spa.

At Master Spas, we make buying a swim spa just as relaxing as owning one.
