R. Nussbaum

What R. Nussbaum does

R. Nussbaum AG is a privately held Swiss manufacturer of fittings and plumbing systems for drinking water installation, sanitary, and heating technology, headquartered in Olten, Canton of Solothurn, and operating under the legal form of a Swiss Aktiengesellschaft. Founded in 1903, the company employs between 251 and 500 people and serves the Swiss market exclusively, positioning itself with the tagline "Wir bringen der Schweiz Trinkwasser" through a regional sales organization (Verkaufsorganisation) covering Switzerland.

The company's product portfolio spans proprietary press-fit and piping systems (Optipress stainless steel, Optiflex-Profix multi-layer, Optifitt, Cupress), brass fittings and valves (Optiarmatur, Easy-Matic, Redfil), pre-wall and flush technology (Optivis-Tec, UPV valves and flush plates), underfloor heating regulation (Therm-Control, Optipress-Therm), heat-pump and water-treatment systems (Aquapro-Ecotherma, Aquapro-Vita), and the UP-Box floor-level distribution concept. The technical backbone is the proprietary 3-Stufenmodell — a three-step framework addressing material selection, temperature, and stagnation to ensure hygienic drinking water installations — combined with 100% lead-free (bleifrei) brass production. Product specification is supported by a suite of digital planning tools (SIA 181 calculator, screw selector, volume calculator, pre-dimensioning, Nussbaum Konfigurator) and BIM integrations with Autodesk Revit, Trimble Nova, and Mega CAD Schweiz AG.

R. Nussbaum makes money primarily through one-time hardware sales to professional installers, planners, builders, and facility managers in Switzerland, distributed via its own regional sales force, the Nussbaum Online Shop (shop.nussbaum.ch), inside sales (phone/email), and as a distributor of complementary third-party brands (Honeywell Braukmann, JRG, Nyffenegger, Kugler, Lyss). A recurring spare-parts business supports the installed base, and free training via the Nussbaum Campus (in-person and webinar) functions as a customer acquisition and retention lever rather than a direct revenue stream. The customer base spans residential construction, hotels, industry/commercial, healthcare, and public buildings, with reference projects including Roche Bauten 2 und 7, Centurion Tower Brugg-Windisch, and Eniwa Buchs.
