A Brief History Of KWC Faucets

Almost everyone with decent knowledge of faucets is familiar with KWC. It is a small Swiss manufacturer of various types of faucets. In the early 1870s, the visionary Adolf Karrer was determined to create a legacy in the realm of plumbing fixtures. Inspired by the magic of Swiss precision engineering, he founded Karrer Wasser- und Chemiefabriken. This is how the term “KWC” was invented.

As time marched on, KWC’s reputation grew significantly. The company maintained a culture of innovation, constantly pushing the boundaries of faucet technology. In 1932, they unveiled the world’s first-ever faucet with a ceramic disc valve. It was a groundbreaking feat that paved the way for modern faucet engineering.

However, in 2013, KWC was acquired by another Swiss company, called Franke Holding AG. But they couldn’t keep the faucet division open for too long. In 2021, they handed KWC over to Equistone Partners Europe. As the 21st century dawned, KWC dazzled the world with touch-control faucets and sensor-activated wonders.
