You’ll be pleased to know that the Jacuzzi® J-345™ comes as standard with a high-quality Bluetooth music system. Featuring 4 x Jacuzzi® speakers that have been installed in key areas, this allows users to hear their favourite tunes whilst the jets are turned on.

Oh, did we mention that the music is equally crisp as it is LOUD!

Many people are keen to know how much it costs to run one of our Jacuzzi® hot tubs, but with every owner using theirs in a different way, it can be very difficult to give an entirely accurate, one-size-fits-all answer. However, what we can tell you is that all Jacuzzi® spas are put through rigorous independent testing by the California Energy Commission (CEC) who set stringent standards for how much energy a hot tub can use.

Thanks to the high-quality design, insulation and smart technology, the Jacuzzi® J-345™ hot tub exceeds these standards by 29%, giving you the peace of mind that you are choosing one of the most energy-efficient spas in the world.

The J-345™ also comes as standard with a thick, well-insulated cover.

The road bridging ancient hot tubs and modern spas is a long and interesting one leading back to the Jacuzzi brothers. After immigrating to California from Italy in the early 1900s, the Jacuzzi family initially made their living as inventors, designing advancements in aviation and water pumps for agricultural use (specifically, orange groves). But it was their submersible pump, the first in the world, which pulled water from the ground that was the first step that led them towards the Jacuzzi^® Brand you know today.

In 1956, a Jacuzzi family member developed rheumatoid arthritis. In an effort to reduce the pain associated with this child’s affliction, the Jacuzzi brothers used their knowledge of hydraulics to create a hydrotherapy pump, the J-300. This pump was portable and transformed any standard bathtub into a rejuvenating spa, launching the wellness industry.

Many years later Jacuzzi has established itself as the go-to brand of hot tubs for the rich, famous, professional sportspeople and anyone seeking the best hydro-massage possible. They’re a top-quality brand that you can trust.

The clarity of your hot tubs water is important to Jacuzzi®, which is why they have integrated their patented U.V. and Ozone combined sanitation system with four-stage filtration.

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

When it comes to massage, the only thing better than a J-300 model is a J-400 model. Seriously, these hot tubs deliver a hydro-massage unlike anything else on the market. So, for those seeking the ultimate in hot tub hydrotherapy, the Jacuzzi® J-345™ is an excellent choice.

The J-300 range incorporates a well-balanced combination of both directional and rotational jets which also vary in size. We especially love the larger rotational jets, these act like a masseuse’s thumbs, making circular motions around key areas of the body. But the best bit is that by using the diverters and the air system, you have full control over the intensity of the massage. Each seat in a Jacuzzi® offers a different experience from the next, we recommend spending 5 minutes in every seat to obtain the maximum benefit that the J-345™ offers.

The Jacuzzi® J-345™ offers an all-seated, social design with every seat facing a centre point. As such, this model has a foot dome located in the centre of the hot tub. Meaning that wherever you decide to sit, you will be able to have a foot massage from the foot dome.

Let’s talk about the captain seat. This seat in particular targets down either side of the spine plus the centre and lower area of the spine. If you’re someone who suffers from back pain or back stiffness, then you will love this seat. But wait… it gets better. This seat also comes with jets that target behind the knees and as with all of the seats in this hot tub is positioned in front of the foot dome.

One of our personal favourite seats in the Jacuzzi® J-345™ model is the seat to the left of the backlit waterfall. This seat includes 3 HUGE, directional jets that target the hips and also the centre spine. We can’t stress how amazing this seat is!

SmartTub® now comes as standard on all J-300 models.
