The company has two three-person hot tubs, and it has eight models which fit either six or seven people. Each of these hot tubs come with different features and star in a different range of PDC’s hot tub series.

There’s three ranges of hot tubs to choose from. The LifeStyle Series is the most affordable of the group, with the Premium Series bridging the gap to the most premium Luxury Series. These tubs come with a 35-year warranty, but the LifeStyle hot tubs get a comparably weaker 10-year coverage.

In total, the manufacturer has 51 hot tub models each of which come with several colors to choose from. These also come in a range of shapes, including oval options, triangle-shaped styles and the more traditional square-shaped designs.

Cal Spas also come with plenty of upgrade options too, so you can tailor your tub to your exact style, taste and needs. But while this means there is a Cal Spas hot tub for every home, this means it can be a little overwhelming when it comes to finding your dream tub. If you’re searching for a Cal Spas hot tub online, it’s hard to directly compare models without speaking to a representative.

So what makes Cal Spas stand out? Out of all the other hot tub companies we researched, this US-based brand is the only manufacturer that offers a saltwater hot tub sanitation option, along with UV-C and ozone options. Other stand-out features include a special hydrotherapy system called the Fountain of Youth.

This feature creates tiny bubbles to increase the amount of oxygen in the water, giving it a silkier feel and encouraging cell and collagen regeneration – hence its name. While another selling point exclusive to Cal Spas is its Adjustable Therapy seat. This lets you adjust your hydrotherapy by controlling the power and type of jet blast.
