Arbonia AG is a Swiss-based company specializing in high-quality interior doors, showers, and glass solutions for architecture and design. Founded in 1874 as a coppersmith's shop in Arbon, Switzerland, it has evolved into a leading European supplier of building components, focusing on wood, glass, and metal products that enhance living spaces with comfort, style, and security. The company offers a comprehensive range including interior and functional doors, digital locking systems, loft doors, partition wall systems, shower doors and cubicles, handles, and building glass, serving residential, commercial, and public sectors from the middle to upper market segments.
