This shower system is cUPC certified as a complete set and complies with ASME A112.18.1-2018 and CSA B125.1-18 standards, helping ensure inspection approval and reducing the risk of rework during installation. The 10 in. rain shower head delivers wide water coverage for full-body rinsing rather than a concentrated spray. An upgraded nozzle design with openings reduced by 40% maintains consistent water pressure while operating at 1.8 GPM (6.8 L/min), meeting California water efficiency requirements without sacrificing flow stability. The system offers 3 spray options-rain shower, handheld spray, or simultaneous use-allowing flexibility for everyday showering, targeted rinsing, and cleaning tasks. Standard US 1/2 in. NPT connections support compatibility with common residential plumbing, and an optional extension kit is available to address valve depth issues during installation. Each set includes a parts map, with components kept in long-term supply and backed by ongoing customer support to support maintenance and replacement over time. Color: Brushed Nickel.
