Curve Spas

Raised Curve Back. Protective Shield. Privacy Wall.

The raised back of our Curve Spas shelter you from the wind as well as provide a private area in your spa. The raised back also allows proper placement of our 24" inch waterfall so the water will Cascade over your shoulders like a warm blanket.

Exclusive 24" Waterfall. The Largest Waterfall on Any Hot Tub

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 into the spa.

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.

Cascade Spas

The world is beautiful. See more of it in a cascade spas.

Coast Spas builds the only portable infinity (vanishing) edge hot tub. Infinity Spas have zero water displacement and no unsightly telescoping skimmers or filter grate. With the largest waterfall, most efficient skimmer and best view - Cascade Infinity Edge Spas are the ultimate hot tub.

With One Edge Removed, Cascade Spas are the only portable infinity edge hot tubs that provide a view that starts at the waterline.

An infinity edge is the perfect feature for a personal hot tub. Not only does it eliminate your filter grate and bobbing skimmers, it also prevents the water level from changing. No matter how many people are in the spa, the water level stays at the manufacturer-suggested level. A self-purging system automatically eliminates air-locks and an included water-level gauge makes it easy to keep the correct amount of water in the included reserve tank.

Coast Spa Features

True Pressurized Filtration. Hydro Cyclonic Filtration System

This system comes with the largest filter available in any hot tub. Coast Spas has the only spas that can accept a 175 sq.ft. filter. 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.

The Strongest Shells. Multiple Layers of Premium Owen Corning® Fiberglass with Steel Reinforcement. Coast Spas® has partnered with Owens Corning® to Deliver the Toughest and Most Durable Hot Tub Shells Available.

Your hot tub starts its life as a sheet of premium acrylic. It is then heated and vacuum-formed to take on the shape of a hot tub, at this point the acrylic is fragile and flexible.

The acrylic shell is then moved to be reinforced using high-grade Owens Corning® fiberglass. A team of specialists start by applying several layers of fiberglass to the shell, then use rollers to compress those layers together. Steel angle iron is then placed onto those first compressed layers for additional support in specific structural areas.

Additional layers of Owens Corning® fiberglass are then added (up to 12 layers or more are typical for an average-size Coast Spas Model) and compressed again, by hand, to complete the shell.reinforcement.
