Features: High Performance™ Pump, WhisperHot™ Titanium Heater, Two Multi Colored LEDs

Dimensions: 93" x 187" x 51"

Inspired by the success of our Swim-Pro Series, the Fitness-Pro F-1537 features both therapy and bench style seating areas with addition of the Cal Spas Exclusive Features. This unique spa therapy section features Rain Jets for a full body massage that helps improve blood circulation to soothe sore muscles after an intense swim. The power of 4 swim jets work in conjunction to deliver a steady swim current with pin point resistance. The swim system features River Jets on top which provide smooth upper body resistance, while the lower jets provide added resistance and lift, making this system perfect for swimmers looking a great aquatic workout to burn calories and increase muscle mass. Over 11-feet of unrestricted fitness area allows for intense treadmill swimming session which keeps the swimmer in place. The swim area also doubles as a “party zone” for a large group!

Fibersteel™ Construction

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 1.5 inch angled irons are added to ensure maximum strength. A final filler coat is applied to seal, bond and toughen the overall structure.

Bio-Clean™ Antimicrobial Filter with TeleWeir Gate

Our Eco-friendly Bio-Clean™ Antimicrobial Filter utilizes a special bacteria-fighting agent that is molded into the fabric. This unique protectant prevents harmful microbes and bacteria from reproducing and re-entering your water system ultimately minimizing the need of chemical sanitizers during regular cleaning and maintenance.

Whisper Hot™ Titanium Heater

Titanium’s inert properties resist corrosion and calcium build up, making it the most advanced and reliable heater in the industry.

Thermo-Shield™ Insulation

Insulation 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 keep moisture out.

Feather Touch Control Panels
