J-315™ Comfort Intimate with Lounge Seat for Small Spaces

  • A small hot tub proves that bigger isn’t necessarily better, whether you’re seeking an amazing hydrotherapeutic massage or a long, relaxing soak in a hot tub. A small hot tub like the J-315™ model can be every bit as wonderful as a larger model, with lounge seating, a Water Rainbow™ waterfall, an LED coloured-lighting system and the CLEARRAY™ Water System. If you have a limited area, or prefer the economy of a small spa, Jacuzzi Hot Tubs J-315 is a superb choice.

Features & Options

Planning a custom hot tub space can be as satisfying as anticipating the hot tub itself. No need for a complete backyard makeover, either. A Jacuzzi Hot Tubs portable hot tub requires only an electrical source and a solid surface for placement. But you can make any Jacuzzi® hot tub uniquely your own with a custom hot tub feeling.


CLEARRAY® Plus 4-stage filtration

CLEARRAY® utilizes the same UV-C technology that beverage manufacturers, municipal waste water plants, hospitals and other health care environments use without producing or adding gas, chemicals, or other by-products to the water as a result. 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.


J-300™ Design

Ergonomically designed seating for comfort, LED lighting for ease of entry and repositionable headrests to perfectly position your body and maximize your hydromassage experience.


J-300™ Lounge

Tension-easing lounge seat (ProAir™ Lounge) with comforting bubbling effect(BX Jets) along with Swedish upper back seats (PowerPro® Therapy Seat), bold lower back jets (MX2), and more deep tissue jets (FX) throughout.


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)

Jacuzzi Hot Tubs introduced these jets, with their unique directional rifling action that creates a spiral stream of air and water – perfect for stimulating small muscle groups. Fully adjustable for high or low pressure, exclusive PowerPro FX Jets have a rejuvenating effect and can help overworked, overstressed muscles and joints.


PowerPro® BX Jets (6)

The BX “Bubbler” Jet represents another Jacuzzi milestone in jet technology. As part of the exclusive ProAir™ Lounge system, this unique patent-pending jet massages the calves with a comforting yet rejuvenating bubbling effect.


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 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.

Rated 4 out of 5 by from Great looks, but needs an update. I purchased my Jaccuzi J-315 a few months ago, and so far, I have been pretty satisfied with it. The jets are almost perfectly placed and very customizable. Each seat has different jets, so if the seat you are in isn't massaging the spot you want, you can move. Part of the reason that I purchased a Jacuzzi brand is the aesthetics. The cup holders are molded into the very nice looking shell. The lighting on it is just fantastic. The specs say that this can seat up to three people. I haven't had three people in it yet. I mostly sit in it with my girlfriend, which the J-315 is just perfect for (every possible seating arrangement is cozy). I was a bit disappointed though in a few aspects of the tub. First, the manual isn't very complete in a few sections. It would have been nice to know what the alkalinity measurement on my test strip meant exactly and what I was supposed to do about it and quite a few sections say to talk to the Jacuzzi dealer, when really, the manual should have that information. Where the tub really falls flat though is in its clunky menu system. Half the time, the buttons don't register that you pressed them and there is a large lag between when the button is pressed and when the menu will respond, so you are never entirely sure what your Jacuzzi is doing. Also, the display itself is sorely outdated, it displays the temperature just fine, but anything more than that is really beyond the display's capabilities. I wouldn't mind the menu so much if Jacuzzi had a decent app where I could control everything from my phone, but I didn't even bother downloading it after seeing the terrible reviews and lack of updates to it.

Rated 5 out of 5 by from Great service for the installation! We certainly have enjoyed the hot tub on a daily basis. It keeps the temperature rather steady.

Rated 4 out of 5 by from a little disappointed The hot tub is great except the waterfall feature is only on with the jets. I am told the 2016 model does not have the waterfall come on when clear ray is activated. The tub was plumbed differently. The waterfall is a nice soothing effect in the other pre 2016 models. If I am being told wrong information please let me know. If this new plumbing is indeed true update your manual. It says waterfall comes on with clear ray.

Rated 5 out of 5 by from Can't kill it! I acquired this model J 315 with the purchase of a home 2 weeks after superstorm Sandy! The previous homeowner had it for a few years prior. Now, to show this units durability. The home is on Long Island, NY. Directly on the Great South Bay! The high surf from Sandy pounded the hot tub. We had 8ft.of water crashing under the house. Thankfully, the home is raised 9ft. However the Jacuzzi is sunken into the deck allowing the waves to have its way with it. There was no damage to it at all! I lost some decking, stairs, a central a.c. unit, and a 12x12 utility shed that made its way 2 blocks down the road! Sure, I have had to some minor maintenance over the years. But this even was only limited to worn house fittings. Honestly, the best unit I have ever could have wished for. Can't kill it!!!!!!!! Sincerely, Bud Stahley
