Learn More. And, a 4-stage water filtration system keeps water clean and free of debris quickly using four stages: ProClear® Filter, ProCatch™ Filter Bag, surface skimmer and a pleated filter.


Jacuzzi® Brand PowerPro® Jets deliver a high volume, low pressure hydromassage through Aqualibrium™: the perfect mix of air and water. As the first company to pioneer jetted water technology, only Jacuzzi® can deliver a massage experience that a legacy that spans nearly 60 years can bring.


PowerPro® FX Jets (8)

Fully adjustable for high or low pressure, exclusive PowerPro FX Jets have a rejuvenating effect and can help overworked, overstressed muscles and joints.

PowerPro® FX Large Rotational Jets (3)

Patent-pending jets that deliver intense hydrotherapy without moving parts, the jets are the larger, more powerful version of the original Jacuzzi FX jets. Their distinct spiral action produces a surging stream of air and water that provides a vigorous massage to larger muscles in the back and shoulder areas.


PowerPro® FX Large Jets (2)

The PowerPro® FX Large Jets focuses on the middle of the back relieving tension and muscle strain, typically caused by poor posture. The FX Large Jet gives a spiral action massage to the back promoting better circulation.


PowerPro® FX Rotational Jets (2)

Using the same FX technology, the PowerPro® FX Rotational Jet focuses on smaller muscle groups with a kneading effect to stimulate surrounding tissue.

Rated 5 out of 5 by from First hot tub, great decision to get Jacuzzi We are new to owning a "hot tub" or "spa". Therefore, we had a lot of understanding to catch up on before we could make an informed choice. Narrowing the elements, building knowledge, determining needs and wants, evaluating the balance between our objectives and the offerings in the marketplace, took time, many many visits to tier one showrooms. And, our friends who had hot tubs gave well-meaning input as well. The single most important bit of advice was to "wet-test" the tubs. Our experience with Jacuzzi was accidental, We had selected several brands to evaluate and had settled on one that we thought met enough of the criteria we had established. As I drove home from the last visit, on the side of the highway was a Jacuzzi showroom, newly established. Recognizing the name, I stopped intending to eliminate this option and validate our earlier choice as "due diligence" to avoid buyer's remorse should I find later that we had made a mistake.. The sales people were different: relaxed, competent, knowledgeable, and it was immediately clear to me that their model that was in our size and performance range completely outperformed the one we had settled on in so many dimensions... and in areas I had been concerned about with the competition. The wet test was the clincher even beyond the obvious quality appointments of its well designed structure, construction integrity, jet configurations, ease of maintenance, looks, and, yes its "feel". It had everything we wanted, compromised nothing in our criteria, and felt just right. We exhaustively tested it, deliciously positioning, and adjusting everything to "be sure" we weren't just infatuated, rather we were in the kind of "informed love" that would endure into a relationship we could be continually be reminded of how good a choice we made. Better yet, we were pampered by the team at Jacuzzi. I am a pretty jaundiced buyer, that having been my profession. every step of the way from our first contact, this team, and I do mean team was fully engaged, coordinated, and committed to making this experience which I entered with great trepidation, a great one. there aren't many of those and this was one... and continues to be, a month after it was installed. We feel cared for and have been immersed in this tub EVERY evening except one since Jacuzzi installed it. That is a story in and of itself, What a brilliant pair of installers. I can't say enough. Gush? Maybe, but well deserved. I would recommend this team and this product to anyone, and would be happy to share my experience with anyone new to this company. I am not easily pleased, but I am happy with Jacuzzi. They earned my serious and deeply skeptical respect, and I smile every time I sit and soak-in the result that could have gone so differently had I never caught their storefront out of the corner of my eye.

Rated 5 out of 5 by from Private Hydro Therapy I am not a germaphobe but the thought of crawling into a public pool / spa,that smells of chlorine or bromine, is not an option. The filtration system is outstanding.

Rated 5 out of 5 by from Best little Hot tub Ever ! Got this a couple months ago and it's the best thing ever on my arthritis and tendinitis ! It is enjoyed by all

Rated 4 out of 5 by from Nice Hot tub I purchased this a month ago and so far I have been pleased with the functions of the tub. I purchased the J315 tub. I'm 6' and the lounge seat is to short to accommodate the calf jets. I wish the filter was on the other side of the tub so I could stretch out. All in all the product is a good product.

Rated 5 out of 5 by from time to relax! i bought this Jacuzzi about 2 months ago and use it several times a week. it helps me sleep better and i've been able to spend more quality time with my wife

Rated 5 out of 5 by from Perfect for Two This is the perfect hot tub for two people to enjoy together. We use it everyday and sometimes twice a day! The optional 110 plug & play power cord is great! We avoided having to pay a large amount of money to an electrician to run a dedicated 220 line. 110 works great no issues after owning for about a month now. It fits perfectly into small spaces.

Rated 5 out of 5 by from Perfect for my needs This hot tub is perfect for me- just wanted something small that I can hop into most evenings to relax. The jets are great (although the leg jets are a little weak), and there is enough room for the occasional visitor. The waterfall is superfluous and a little silly. I'm looking forward to cooler weather.
