Cabinet and Panel Enhancements

Engineered to Keep Your
Hot Tub Warm in Any Climate.

State-of-the-Art Accents

Cal Spas hot tubs are constructed with elegant and durable paneling to protect your investment and add everlasting sophistication to your backyard hot tub retreat. Our unique cabinet panels protect the spa equipment from the elements and can be easily removed for maintenance purposes.


The spa cabinet is an integral part of the construction of the entire hot tub. With durable integrated framework, our cabinet frames are strong enough to support even the largest hot tub designs. All Cal Spas cabinets feature a reinforced wall made of treated lumber that is bracketed and reinforced at the corners. To provide additional support, wood support beams are attached directly to support the seating area. Our cabinets also feature an equipment access door, equipment enclosure which isolates the equipment, and fresh air vents to provide the motors with cooling, fresh air.


Cal Spas also provides additional protection for the bottom of your hot tub with the resilient ABS Molded Bottom Tray. This tray locks the heat in and seals out moisture, while protecting the hot tub’s underside.

Advantages to Cal Spas state-of-the-art cabinets include:

  • No warping, shrinking or decay

  • No cracking, splitting or chipping

  • Maximum heat retention for lower operating costs – energy efficient!

  • Removable panels for easy access Moisture resistant Soundproof
