Premium Options

iPod docking station with FM radio

Set the mood with your favorite music straight from your iPod to your new Spa! This option also features an FM transmitter, 4” speakers and water resistant remote control.

LED lighting

With several distinct color modes available, you pick the mood you would like to set. Then display your favorite color through your spas jets and around the top perimeter.


This innovative waterfall is designed with an adjustable control and will compliment any outdoor space. The tranquil sound of cascading water is exactly what you need to inspire the deepest of relaxation.


The addition of an ozonator is an eco-friendly, efficient, and safe sanitizing solution for your spa. Bacteria are killed 3,000 times faster than traditional chlorine or bromine. Ozonators will save you time and money. Ozone is the most powerful oxidizer and disinfectant that can be safely used in spas. More effective than chlorine, ozone creates no harmful by-products because it is a natural process, not a chemical.

Full Foam Insulation

While all of our spa shells are insulated with the highest grade of closed cell foam, some environments demand a little more. If you’re in an extremely cold climate, you can save energy and retain more heat with full foam insulation. This process fills the entire cabinet of the spa with insulation.


Our spa covers are made from 100% marine grade vinyl and a tapered angle downward from the center to drive off rain and prevent precipitation from pooling. Every cover also includes safety straps that employ a lock and key device to protect young children from unsupervised entry

Cover Valet

The Cover Valet is a dual gas spring system that will assist in effortlessly lifting and lowering your spa cover. A locking safety feature holds the cover open until it is time to close up shop.


Our synthetic spa steps are designed with style, safety and longevity in mind. These steps come in a variety of colors to match the cabinetry of your spa.

Spa Side Handrail

Probably the most user friendly spa side assistant on the market. This handrail is designed to provide 360° of movement to allow for easy entry and exit of your spa. The end of the rail is complimented by a battery powered blue LED light.

Chemical kit

You don’t have to be a mad scientist to keep your spa clean. We offer you this simple kit filled with the essentials. Our spa chemical kit has everything you need to keep the water clear at an affordable price.
