d line unifies architectural hardware and plumbing with PVD finish system

architecture-design · 2026-07-09

Danish design brand d line has introduced a unified design system that ensures seamless finish consistency across door hardware, plumbing collections, and bath accessories. Using Physical Vapor Deposition (PVD) technology on marine-grade AISI 316 stainless steel, the brand eliminates the common problem of mismatched finishes between levers, faucets, and shower controls. The PVD process bonds color at a molecular level in a vacuum environment, creating surfaces resistant to scratches, moisture, and harsh detergents. The PVD Copper finish offers a warm, vibrant alternative for contemporary interiors, pairing well with concrete, terrazzo, and matte surfaces. d line's digital Mood Board Tool allows designers to browse the catalog, compare products, and finalize material palettes before installation. The collection includes Knud Holscher's door hardware, the Qtoo plumbing line, and coordinated bath accessories. Bridgeport Worldwide distributes the collection.
