Villeroy & Boch Spas are engineered to be more powerful without using more energy. This “PowerPlus” concept means that you will have more powerful spa jets without having to use a larger pump. With a Villeroy & Boch Spa there is much less plumbing per jet, and consequently less water friction. The unique JetPak™ plumbing design of a Villeroy & Boch Spa allows every jet in the spa to run at the same time. All conventional spas have diverter valves that run only some of the jets at any one time because they do not have enough power to run all the jets simultaneously. In a Villeroy & Boch Spa, every single person in the spa can enjoy their customized massage together.
