What Hamberger Industriewerke does
Hamberger Industriewerke GmbH is a privately held, family-owned German industrial company headquartered in Stephanskirchen near Rosenheim, Bavaria, founded in 1866. Following the Q1/Q2 2026 carve-out of its Flooring Business (HARO parquet and hard floor coverings, ~EUR 150M revenue) to Mutares SE & Co. KGaA, the company operates two divisions: Hamberger Sanitary GmbH, which manufactures toilet seats under the HARO (premium specialty retail), Cedo (home improvement/DIY), and OEM brands for global sanitary ceramics manufacturers; and a Real Estate Management and Development division handling the group's own property portfolio.
The Sanitary division is the European market leader for WC seats, producing approximately 8 million units per year and offering over 350 models with 120,000 combination possibilities through a proprietary Modular Baukasten-System, supported by patented SoftClose® and TakeOff® technologies and 120+ mounting solutions. Production is highly automated in Germany and Bulgaria, with on-site biomass and hydropower plants providing a structural energy cost advantage. The company holds long-tenured certifications (ISO 9001 since 1995, ISO 14001 since 1998, PEFC since 2002, ISO 50001 since 2012) plus Blue Angel and Climate Partner climate credentials.
Revenue is generated primarily through B2B hardware sales of manufactured WC seats, with OEM contracts and a 50%+ export share distributing volume across more than 70 countries. The company is led by Managing Directors Ralph Wonnemann and Michael Huck, employs over 1,150 people globally in the Sanitary division, and reported EUR 115 million in Sanitary revenue in 2025.
