Jacuzzi J-335™ - Main features

As you can see, the Jacuzzi® J-355™ has many features, some patented to the Jacuzzi® brand, and some exclusive to the J-300™ collection. These come as standard on all J-335™ Hot Tubs and won't be an extra cost, as they might be with other brands. 

Jacuzzi® J-335

Premium LED Lighting   

The J-335™ has access to a much more diverse lighting package with the Prolite™ range, adding to the hydrotherapy hot tub experience with light therapy, either via a carousel of colours or a fixed colour that helps set the mood and induce a relaxed state.  


Prolite™ gives access to features that are not available in lower collections, giving you added richness to your wellness routine.  


PowerPro® Range 

The J-335™ utilises advanced Jacuzzi® PowerPro® jet technology, which is an upgrade from the ClassicPro™ range found in lower spec models. 


One of the main features of the J-335™ is the significant increase in both hydromassage variation and quality you can expect. The PowerPro® range provides a broader variety of jets, in numerous sizes, able to rotate and target specific areas of the body for maximum effect.  


As a more advanced hydromassage package, the J-335™ gives plenty of room and hydrotherapy hot tub options in the different seats, utilising the PowerPro® jet range for a much deeper impacting massage.  

ProFinish™ Cabinetry  

The ProFinish™ cabinetry seamlessly combines durability and style to enhance the aesthetic appeal of this hot tub.

This advanced design integrates high-quality, UV-resistant materials, ensuring tool free, easy access to essential parts and plumbing. Not only does it provide a sleek appearance, but it also remains resilient against the elements, maintaining its pristine condition. 


Another great feature that works alongside the cabinetry is the durable ProPolymer™ base, which is highly resistant to moisture and the environment, providing a solid foundation for the rest of the hot tub to sit on. 

Hydrosoothe pillows

Hydrosoothe™ Pillows 

Exclusive to Jacuzzi® J-300™ collection, the Hydrosoothe™ massage pillow is a distinctive feature designed to enhance comfort during your hot tub experience. Crafted with water-resistant, soft fabric- this pillow allows you to rest your head comfortably while receiving a soothing massage to the back of your head and neck. 


As water cascades onto your shoulders, the Hydrosoothe™ pillow provides an additional layer of relaxation, relieving tension headaches, neck pain, and promoting muscle relaxation. This unique feature is only available with Jacuzzi® hot tubs. 

SmartTub™ Compatible  

Another feature is the optional SmartTub™ system, another Jacuzzi® patented feature. You can either upgrade to SmartTub™ when you purchase, or after you've purchased a Jacuzzi® hot tub. 


SmartTub® allows you to remotely monitor your hot tub system health, control the temperature, turn off specific parts as well as lockdown the hot tub’s programmes, all from your smart device.

The SmartTub™ app can be used via cellular communication, rather than WIFI for its stable connectivity (that's exclusive to Jacuzzi®). This means that no matter where you are, you’re in control.

How much does the J-335™ hot tub cost?

The Jacuzzi® J-335™ has an RPP of £11,999.

Is the Jacuzzi® J-335™ energy efficient?

On average, Jacuzzi® UK customers use an average of 4kWh to run the J-335™ Hot Tub. This works out at around £1.36 a day at the current 34p per unit. To put that into perspective, it is less than a family of 4 taking a 10 minute shower a day. 

(This is based on data collected from 1,850 SmartTub®s from Jan 1st 2022 to December 31st 2022 which includes real world usage.)

So the answer is, yes the Jacuzzi® J-335™ is energy efficient as it includes these features:

  • It meets and exceeds California Energy Commission (CEC) standards by 29%.
  • Includes CLEARRAY Active Oxygen™ clean water system. It reduces chemical usage and helps your hot tub run more efficiently.
  • ProLast™ hot tub cover which help retain heat in the water.
  • Full foam insulation to maximise heat retention in the cabinet area.
  • Optional SmartTub™ to track your energy usage and use features such as Smart Heat Mode and Holiday Mode.

Who is the J-335™ good for? 

The J-335™ is an exceptional hot tub for providing an enhanced hydromassage hot tub experience with powerful jets designed to deliver a deeper massage.


The J-335™ could be well suited to you if you like socialising. With seating for up to 5-6 people, everyone can sit comfortably in the ergonomically designed seats, while one person can enjoy the lounge seat for a full-body massage experience. 


This hot tub is our best all-rounder tub for those looking for premium massage while also being a great social and family spa to enjoy. 


Who is the J-335™ not a good fit for? 

If you’re looking for the absolute premium features, both in hydro technology and additional features, then a hot tub such as the J-475™ from the J-400™ collection, may be a better option for you. 


With the J-335™ being a premium hot tub, it does come at a premium price of RRP £11,999. If you’re on a budget or looking for a hot tub that prioritises socialisation over hydrotherapy, then something in the mid-range price bracket might be a better option. 


Pros of the J-335™

  • Hydrosoothe™ massage pillow - Headache relieving, extra hydrotherapy 
  • PowerPro® jet range - Exclusive jets and therapy seats 
  • Shell designStylish, curved and unique shell 

Cons of the J-335™

  • Lounge seat - The lounger is that the lounger seat leads straight into the corner seat so if you are particularly tall, your feet could be in the persons lap in that seat 
  • Premium hot tub - Might be out of some people's price range 
  • Hydrosoothe™ massage pillow - There is only one pillow of the four that is HydroSoothe which limits who can benefit from that massage at one time

The J-335™ is compact enough to fit in most gardens while being spacious enough for five people to sit comfortably, making it a great socialisation space. 

Whether you want to incorporate daily hot tub hydromassage into your wellness routine or create a space for relaxation and stress reduction, the J-335™ could be the perfect addition to your home. 

The combination of design, hydrotherapy, and being a great social spa is reflective in the price. Those that lean more to the social side could consider the J-200™ collection or those wanting to have our best hydrotherapy jet technology and higher spec technology features may want to take a look at the J-400™ collection
