Always Perfect

In a Coast Spas® Cascade Series Spa, the water level will always stay the same regardless of how many people are in the spa. No wasted water caused by overflow means less chemical usage and no additional energy wasted to heat the water, resulting in a smaller environmental impact. When your guests leave the spa, it automatically fills itself back to the same level.

No Filter Grate

You’ll never have to share your hot tub with loud skimmers that suck water down into your filtration system. Gone are the days of the floating telescope skimmers that take up the area of one seat or more. Your vanishing edge waterfall does all the skimming of your spa water using our patented vanishing edge design and with the pressurized commercial-grade Hydro Cyclonic Filtration System®, you will never sit in your hot tub with your filter cartridge again.

Ultimate View

No other portable hot tub in the world can give you the same unobstructed view from your hot tub. Our patented vanishing edge design allows bathers to look out at an unobstructed view, beginning at your spa’s waterline.

Largest Skimmer

Having the largest skimmer available will supercharge debris removal from your spa. Replacing the traditional “bobbing telescopic” skimmers, your vanishing edge not only skims your spa water quicker and more efficiently… but looks fantastic doing the job.
