J-400™ High-Back Design

The exclusive high-back Jacuzzi® silhouette, premium LED lighting throughout and backlit waterfall that cascades down your neck and back make J-400™ Hot Tubs a sight to behold.

In addition, PowerPro® jets that rotate and swirl pamper, stimulate and penetrate your muscles from your neck to your feet in upright seats.

The full-color ProTouch™ Control paired with the ProLink™ app helps you stay informed of the status of your hot tub, schedule maintenance reminders and adjust temperature and jet functions.
