Spa Cover
IST spa covers are crafted to fit your spa model. Each cover seals in heat with a thick 4”/3” foam insulation, more energy efficient. Feature locking clasps to keep heat in, debris out. Easy to clean and attractive, IST spa covers give your spa a great finishing touch.

Filtration System 
50 sq. ft. of filtration surface, assuring a cleaner, fresher spa. The filtration system assures all water is circulated; meaning 100% of the water is filtered . Now that’s filtration! You can rest assured that your IST spa is hard art work keeping ALL your water — above and below the surface — fresh and clean.

Woodless Casement
Unlike most other spas today that are built on wood framing, IST features a one-of-a-kind composite Casement system.

Plus, all components are easily accessible in the unlikely event of service.
