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

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.


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.


Self-Cleaning Sweeper Jet

Automatically Clear Debris and Contaminants From the Floor Of Your Spa.

It is inevitable that dirt, sand and other debris will find it’s way into your hot tub. It can be brought in on your feet, blow in by the wind or simply fall from the trees or a structure above. Regardless of how it got into your hot tub, the last thing you want is for it to stay in your water – collecting over time on the floor of your spa. Our Self-Cleaning Sweeper Jet is activated during the filtration cycle and blasts the collected dirt, sand and other debris off the floor to where it can be drawn into the filtration system. It’s incredible how something so small could make such a difference to your hot tub enjoyment.

Xtreme Pumps

Built Powerful for Jetted Hydrotherapy. Intelligently Engineered for Energy Savings.

Meet the Coast Spas Extreme Line of Jet Pumps. From the Monster Flow 7HP pump to the 1.5HP Smart Flow pump, all are designed to push the maximum allowable pressure through to our specially designed Luxury Trillium Massage Jets. During your spa’s filtration cycle, your jet pumps are activated to pull and push water through your hot tub filter. During the filtration cycle, our highly efficient pumps will run on an ultra low voltage (1.2Amps for 5HP Super Flow Pumps) and at one third the RPM (3450 high / 1150 low). Programmable filtration cycles allow you to control when, and for how long, your jet pumps activate to purge your hot tub of debris. During the programmed filtration time, your hot tub pumps will consume about as much power as your backyard aquarium pump.


Lit Carbon Fiber Corners

Add Carbon Fiber Corners to Your Synthetic Cabinet.

Beautiful 9″ wide durable synthetic cabinets are available with our exclusive Lit Carbon Fiber protective corners. These innovative corners light up at night, automatically triggered by the included ambient light sensor. If an Extreme Lighting Package is installed on your spa, each corner will light up to match the color of light in your hot tub. Each synthetic panel is lined with a thick layer of dense foam topped with a heat reflective foil, preventing heat loss and saving energy.
