Cover Options 

Coast Spas Sunstar cover use only virgin foam cores to save you money and provide you a stronger, more durable, and more energy-efficient cover. 
The exclusive, proprietary plastic is more effective than what other manufacturers typically use. Sunstars specially formulated material reduces vapor transmission and still has the strength, flexibility, transparency, and seal-ability we require. Equally important is the perfect heat seal seam. Sunstar uses an impulse sealer that makes a perfect seam using the right combination of temperature, pressure, and timing. Unlike the less expensive hand-held sealing machines, all human variables are eliminated so your cover makes a perfect seal every time. 
Sunstar’s end pillow and full length heat seal are all specially designed to help save heat and prevent moisture loss for long-term energy savings. 
Sunstar meet the ASTM Safety Standard along with other manufacturers and we have gone a step further to be independently UL Classified.

One of the most important functions of the hot tub is filtration. The performance of your filter will impact the water purity, clarity, chemical consumption and even the equipment inside the hot tub.  
Coast Spas have the most effective water filtration system on the market. This system is commercial grade, taking the filter cartridge out of the bathing area. This prevents contaminates from re-entering the water when the pumps are not running and while removing the cartridge for cleaning. This secures the integrity of your hot tub water so you can enjoy the benefits of clean, clear water within your hot tub.  
Filtration Systems 
Sliding Weir Door: Small and compact yet extremely efficient skimmer for the small compact hot tubs. 
50 sq.ft Pressurized Filtration: A compressed pressurised filtration system to accommodate compact hot tubs models. 
100 sq.ft Cyclonic Filtration: Commercial grade pressurised filtration for the clearest water. 
175 sq.ft Cyclonic Filtration: The industries largest and most efficient pressurized filtration.

1. Water is taken into the system through the skimmer and suction ports. 
Coast Advantage: The refresh button activates filter cycle on demand and the sweeper jet blasts any debris, on the spa floor, up and into the skimmer and suction. Coast spas have large skimmers that move more water than the traditional designs. 
2. Working its way through the plumbing to the heater where it is instantly increased in temperature. 
Coast Advantage: The extra large 3" plumbing increases the amount of water supplied to the pump, heater, filtration and purification system. 
3. Water then travels to the spa pump where it is then powered through the rest of the system. 
Coast Advantage: Coast Spas have high horse power pumps that have been custom engineered to run on low speed during filtration cycles. 
4. Next the water travels through the filter cannister where particles smaller than the eye can see are captured. 
Coast Advantage: Exclusive pressurized commercial grade filtration with an available 175 sq.ft filter cartridge. By far the most advanced and effective filtration system available. 
5. The majority of the water now travels to the jets in the hot tub where it is mixed with air before delivering a generous massage to the bather. 
Coast Advantage: Coast Trillium jets give you a deep tissue massage simulation with strategically placed jets to maximise effectiveness. They are also adjustable by simply turning each jet to allow more or less water pressure. 
6. Some of the water travels to a mazzei injector which employs a venturi effect to draw ozone that is produced by the spas ozonator. 
Coast Advantage: Coast offers the O3 One Plus Ozonator which produces a higher concentration of ozone, further increasing the level of sanitation in your spa. 
7. Water then travels to the salt water generator (if installed) where electrodes connected to the regulator box constantly produces salt water. 
Coast Advantage: Our EcoClean salt water generator produces softer water that is gentle on sensitive skin, odour free and eco friendly. 
8. The ozone rich salt water now travels to an expansion chambers which increases the efficiency of the ozone. 
Coast Advantage: The Crystal Clear Purification Chamber boosts ozone efficiency. 
9. The water then exits though the drain in the bottom of your spa. 


O3 One Ozonator 
Injects ozone into your water and kills bacteria on contact. One of the most effective purification methods. The O3 One Plus Ozonator produces a higher concentration of ozone (more ppm) than the O3 One ozonator. 
Crystal Clear Purification Chamber 
Ozone mixing chamber for increased ozone efficiency. Give ozone increased access to organic materials while in their energetic state increasing it's efficiency. 
Ecoclean Salt Water System 
An eco-friendly alternative to using chlorine as a method of sanitizing your hot tub. The continuous generation of sodium chloride reduces the amount of sanitizers needed for operation. The water is softer so an ideal option for sensitive skin.

Coast Spas has launched the AquaSole Massage System, specifically targeting the feet. Consisting of two large “foot massage” jets in the footwell of many of the spa models, the AquaSole Massage jets are designed to provide gentle and rhythmic massage from the top of the toes through the arch and to the bottom of the heel. The user simply presses their feet against these jets and the swirling water action works on all the areas of the feet. Meanwhile the powerful high-flow volcano jet aims to give a totally different but complementary massage. 
The two different jets and hydrotherapy pattern are designed to work together as an integrated system to rejuvenate tired and sore feet. All jets are adjustable, and water can be channelled as required by Coast Spas’ water diversion controller. Feet are connected to all other areas of the human body through muscle and nerve endings, and that massaging them can have positive affects in many different areas and help with pain relief, anxiety and tiredness/soreness. 
Benefits of the MicroSilk® System 
•Removes impurities from pores 
•Leaves your skin silky smooth 
•Plumps and hydrates skin 
•Energizes skin cells 
•Kills bacteria 
•Promotes tissue healing 
•Improves serotonin levels 
MicroSilk® is a revolutionary skin treatment system that uses oxygen to stimulate collagen production in your skin. Your skin’s natural collagen production gradually subsides as you age. This reduction in collagen levels leads to the thinning of your skin which causes fine lines, wrinkles and the appearance of age spots. 
Exposing your skin to MicroSilk® for just 20 minutes a day will re-stimulate collagen levels leaving your skin looking smooth and beautiful and removing years from your appearance. 
The MicroSilk® Pro System from Coast Spas combines the age-defying MicroSilk® system with our commercial-grade pressurized filtration system, keeping your water clean and clear for your daily beauty routine.

Coast Spas use energy efficient pump motors. These use as little as 1 amp of power on filtration and heating cycles. 
The Cyclonic Filtration provides the most efficient filtration in todays hot tub industry. This results in shorter overall running time and reduces power consumption. 
A wide range of insulation options are available. Full foam insulation is available on most Coast Spas models to maximize heat retention and minimize power consuption. Full foam also helps support the pipe work within the hot tub. 
Each hot tub model has its own Sunstar custom designed insulating cover. These reduce heat and moisture loss. Energy saving baffles, at the centre seam, seal your cover to keep the heat in. 
The control panels allow you to run you hot tub in Economy mode which will only heat the water during filtration cycles. This reduces the running cost for people who do not use their hot tub on a regular basis but still protect the water from freezing in harsh conditions.
