Short answer: the J-335 is a 5-6 adult spa with 42 jets and 360 gallons of water, sold and installed only through Jacuzzi dealers. It is the largest spa in our catalog. There is no published price and no plug-in mode in our data, so treat it as a project with a site visit.
How heavy is 360 gallons?
The water alone weighs about 3,002 lbs (360 gal x 8.34). Our data has no dry weight, so the true filled figure is higher, and 5-6 adults add more. The shell is 84” x 84”, which is 49 sq ft. Water alone works out to about 61 lbs per sq ft.
Plan for a reinforced concrete pad or an engineered deck. Also check the delivery path: a 7 ft square shell that is 36” tall has to get through your gate, usually on its side.
How much energy does a fill take?
Raising 360 gallons from 60°F to 102°F takes about 37 kWh before heat loss (360 gal x 8.34 lbs x 42°F, divided by 3,412). The electrical requirement isn’t in our data. Ask the dealer for the voltage, the breaker size, and the heater wattage, then get an electrician’s quote before you commit.
Here’s what the spec sheet won’t tell you
- Price, which varies by dealer
- Electrical requirements
- Dry and filled weight
- Warranty terms
- Delivery, crane, and installation fees
Ask for one written quote that lists each of those as its own line.
You get, you give up
You get 42 PowerPro jets across several seat styles, a lounge seat with a jetted pillow, and Jacuzzi’s True Water filtration, which the brand describes as a nanobubble system. You give up online checkout and price transparency.
How it compares
The AquaRest Discover Premium 600 also seats 6, holds 240 gallons, and lists at $3,479. It has 29 jets against 42. Bottom line: get the J-335 quote, then decide whether 13 more jets and a dealer install are worth the gap. Start with 6-Person Hot Tub: What Changes at This Size.
