Energy Efficient Hot Tubs

Easy to Own, Easy to Enjoy

Better insulation means low energy costs. We use environmentally-friendly foam technology that has dramatically raised the standard over urethane foam insulation systems used by almost all U.S. spa manufacturers. It allows foam to be sprayed without ozone-destroying gases and without gas emission hazards.

Master Spas keeps the heat in so your electric bill is lower

High Quality Insulation

The Foam Insulation System expands to 100 times its initial volume in seconds to insulate and air-seal the spa. The resulting blanket of soft foam insulation forms a continuous thermal barrier that eliminates cold spots and significantly reduces energy costs.

A consistent, comfortable temperature is maintained inside the spa, while cold air is kept outside, and condensation, mold and mildew prevented. Unlike urethane foam-based systems, which lose half their value in as little as two years, our environmentally-friendly foam maintains its insulation value for the life of your Master Spa.

Energy Efficient

Quality construction and energy-efficient materials help keep energy costs low. The full-foam insulation and a snug-fitting cover work together to maintain water temperature.
