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.

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.
Perfect Spa
