* Powder coated box steel provides the toughest, most durable frame you'll find anywhere.

* Box steel reinforcements give the frame's top flange greater strength.

* The frame is finished with a vac formed high density polymer base that helps keep the heat in and the unwanted pests out.

* High Tech Polar Wrap provides a continuous thermal barrier that eliminates cold spots and significally reduces energy costs. The silver coating on the inside of the wrap reflects heat back under the skirt where it belongs.

* Iceynene foam insulation makes a Master Spa one of the most energy-efficient spas in the industry. It also helps support the weight of the plumbing in the spa. Master Spas meet the stringent standards set by the California Energy Commission.

* Our manifold plumbing system ensures that pressure is distributed equally among the spa's jets.

* Our DuraMaster™ skirting is made of high-impact weatherable polymer. It features authentic wood grain patterns randomly etched into the polymer for a rich, three-dimensional look. And it's easy to care for with a cloth and garden hose with virtually no fading or color change.

* For added peace of mind, built-in Microban® antimicrobial product protection* is added to the Lucite® acrylic shell* to inhibit the growth of bacteria that cause odors and stains.
