Step into a Jacuzzi J-400 Designer Collection hot tub and let the inventors of the modern hot tub help you step outside the box. In creating the J-400 Collection, Jacuzzi designers and engineers were inspired to rethink traditional hot tub design. And the ingenious result literally breaks the mold by taking Jacuzzi WaterColour™ waterfall technology to new heights. Graceful curves present a contemporary profile – and a natural backdrop for cascading water and light. This Jacuzzi hot tub will change the way you see water and experience hydrotherapy.
