J-345 Summer or Winter Feel-Good Centre

The J-345 hot tub is an improved version of what was already one of Jacuzzi’s most popular hot tubs. It’s a best seller partly because when people buy hot tubs, they look for balanced design and dimension. The J-345 is just that – perfectly proportioned. It’s loaded with PowerPro® jets and body-hugging seats, two more reasons to buy a hot tub from Jacuzzi. Like other models in the Collection, the J-345 has been fitted with new, brighter lighting, including illuminated pillows and cup holders, a redesigned waterfall and an improved filter shield.

Want to transform your backyard into a year ’round entertainment centre? Take your time before you buy. Hot tub owners recommend Jacuzzi for their reliable performance and quality materials. Don’t forget to check out our beautiful spa accessories by Jacuzzi Exclusives™ for “must have” items including spa steps, stools, convenient tables, and luxurious apparel.

CLEARRAY® plus 4-stage filtration

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.

Acrylic Shell Colors

The Jacuzzi TriFusion™ System produces a durable acrylic spa shell that is eight times stronger than conventional fiberglass shells and rich in color and texture.
