THE WORLD IS BEAUTIFUL, SEE MORE OF IT IN A CASCADE SPA

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.

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.

Xtreme Pumps

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

Meet the Coast Spas Xtreme 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 Xtreme 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.
