Hot Tub Construction

Fibersteel™ Contruction

Durability is paramount with it comes to your home investments. That's why Cal Spas hot tubs utilize the exclusive Fibersteel™ Construction Process. The finest acrylic sheets are vacuum molded into shape, then reinforced with vinyl ester and fiberglass. After curing, the shell receives a resin filler coat, fiberglass and calcium carbonate. Stiffener reinforcement supports and 1 inch angled irons are added to ensure maximum strength. A final filler coat is applied to seal, bond and toughen the overall structure.

Reinforced Framework

Reinforced Framework

Each Cal Spas hot tub is built on a structure of pressure treated wood that resists corrosion, decay and insect damage. The frame is constructed from a sturdy design of rails and cross-bracings which are secured by 1 inch galvanized staples for sold strength, while vertical supports are shored with plywood corner gussets and vertical angle bracings.


Cal Spas Thermo-Shield™ insulation system starts by installing a unique material primarily comprised of post consumer recycled denim. This 3” thick insulating material foundation is then thermally bonded with a 99% pure aluminium reinforced foil sheet on one side creating a radiant heat shield which directs motor and equipment heat back into the spa, retaining residual heat and increasing energy efficiency. Next, we install a layer of dual walled reflective bubble foil to the floor area of the spa to reflect heat upward into the spa seat and floor. Finally we add an ABS liner or ABS moulded pan that locks in heat and keeps moisture out.

Full Foam Insulation

Insulation is one of the most important aspects to consider when purchasing a hot tub. By incorporating high-quality insulation into the spa structure, Cal Spas is reducing the time it takes for the water temperature to pass from the body of water to the outside environment. By effectively doing so, the time that it takes to heat and maintain water temperature is reduced and in return, saving you money on your electric bill.

Bio-Clean™ Filter System

A special bacteria-fighting agent is molded into the fabric of the filter and prevents harmful microbes and bacteria from reproducing. A TeleWeir Gate prevents debris from re-entering your water system.

PureSilk™ Ozonator

The Eco-friendly PureSilk™ Ozonator by Cal Spas instantly kills bacteria through exposure to the Ozone while minimizing chemical usage. It features exclusive moisture-sensing technology that delivers virtually maintenance-free operation. The unit automatically shuts off when moisture is detected inside. Once the moisture has dissipated, the unit starts again automatically.

Synergy™ or Hybrid Clear™ Water System

Combining Ozone and UV water treatment technologies to reduce the use of chlorine, bromine and other sanitizers to treat a closed water system formulates the Synergy™ System. Water is treated by combining water filtration and purification technology.

CalPure™ Salt System

Sodium bromide (NaBr) is an effective bacteria killer that should be part of every hot tub's water clarity regimen. The eco-friendly CalPure™ II Salt System instantly turns salt into bromine to keep your hot tub water clean and fresh. This perpetual sanitation cycle kills bacteria, algae and other pathogenic organisms without ever requiring additional sodium bromide. A dedicated digital topside display monitors the salt levels of your spa at all times. The CalPure™ II Salt System also eliminates the need for an Ozonator.
