Cascade Spa Features

Infinity EdgeDesign

Always PerfectIn 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 GrateYou'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 ViewNo 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 SkimmerHaving 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.
Exclusive 24" Waterfall

The Largest Waterfall Available on Any Hot Tub
At one time waterfalls were just to add soothing sounds and a relaxing ambiance to your spa. Coast Spas® changes that by putting you into the waterfall, giving you a feeling of pure relaxation and complete tranquility. Our largest water feature comes standard on nearly all of our Curve and Cascade Series Spas. This continuous blade of water measures a full two feet across and is fully lit with vibrant LED Lights. Fully adjustable, the 24" waterblade can explode into the middle of your hot tub or softly drop inches from its source (and everything in between). The Coast Spas exclusive 24" waterfall is the largest available on any hot tub. Enjoyment is guaranteed.
Curve Series Design

The Ultimate Spa Design with the Largest Waterfall Available.
Our Curve Spas have changed the definition of a hot tub. Why have a conventional spa when you can own a Curve Spa by Coast Spas? The sleek and stylish raised back design gives you protection from the elements as the acrylic shell comfortably wraps you in its warmth, offering both privacy and shelter. You can watch, hear and feel the true benefits of the curved design with Coast Spas' 24" waterfall. Accent the mood with one of many LED lighting options that will brightly illuminate this exclusive water feature.

Curve Spas come standard with a pressurized commercial-grade Hydro Cyclonic Filtration System®, plush headrests, large water features, Self-Cleaning Sweeper Jet and much more.
Hydro Cyclonic Fitration System

Commercial-Grade Pressurize Hot Tub Filtration System
Only from Coast Spas®.
In North America it is law for any commercial establishment to have a closed pressurized filtration system on any public pool or hot tub. Not only is it more efficient and faster than a skim filtration system but it also removes the dirty filter canisters from the bathing area. Without a pressurized system, once the water flow to the filter subsides, the debris that was caught in the filter is free to float back into the spa and re-contaminate the water.

We like this idea about as much as sitting in the water with the dirty filters. So Coast Spas developed the Hydro Cyclonic Filtration System®. This is a commercial-grade, pressurized filtration system with the filter canister completely removed from the bathing area and coupled with an oversized skimmer. We feel so strongly that the happiest spa owners have the cleanest water, that we made this a standard feature on ALL of our spas. So you can rest easy knowing that your spa will have the best filtration system available.

The Benefits of Hydro Cyclonic Filtration -No dirty filter sitting in the hot tub water with the bathers. -Captured contaminants will not re-enter the spa water when changing the filter or when pumps are deactivated. -The Water Diversion Blade® disperses water and contaminants evenly around the outside of the filter resulting in more efficient filtration. -Up to 175 sq.ft. of filter media (largest available in any hot tub) for superior water flow and less strain on your spas' components.
Sweeper Jet Self Cleaning

Cleans Right to the Bottom of Your Spa
When you step into your spa, any particles that are insoluble in water that are brought in with you (such as sand) will settle at the bottom of your spa if uncaught by the filter. In all other hot tubs, once these particles have settled onto the bottom of the spa you will have to share your spa with them until either you drain and clean the hot tub, or purchase equipment that will pick them up. Unfortunately, sharing your spa with these little particles means that you will have to endure an undesirable gritty texture when stepping in your hot tub and spa vacuums are not always the cheapest accessories to purchase. Coast Spas saves you all the trouble and money with the Self-Cleaning Sweeper Jet. The Sweeper Jet is positioned near the spa floor with its fan-like nozzle aimed downwards, and is automatically activated on daily filtration cycles. The sweeper jet blows all the particles resting on the floor of your spa up and into the moving water to then enter the filtration system. Here's to a spotless grit-free hot tub, without having to lift a finger.
