JetPak™ technology. As you’d expect from Villeroy & Boch, the SP- and SR-line are designed to be the most advanced spa ranges available. As such, it incorporates an unique innovation: JetPak™ technology. This technology is protected by patents and achieves significant technical advantages over other spa designs.
Full-foam insulation. The SP- and SR-line are completely filled with closed-cell foam insulation. This limits heat transfer and maximises energy efficiency.
Fewer connections for 100% pressure.
