Is Grohe owned by American Standard?

No, Grohe is not owned by American Standard, but both Grohe and American Standard are owned by the same parent company, Lixil Corporation, which is why they are often confused as being related. GROHE is a German faucet and shower brand founded in 1936 in Germany, headquartered in Düsseldorf. American Standard is an American plumbing brand founded in 1875 in the US, headquartered in Piscataway, New Jersey, and is the largest plumbing brand in North America known for toilets and faucets. In 2013, Lixil Corporation, a Japanese building materials giant headquartered in Tokyo, acquired American Standard Brands for $342 million. In 2014, Lixil, together with the Development Bank of Japan, acquired GROHE Group for about $4.1 billion euros. So since 2014, both GROHE and American Standard have been sister companies under Lixil ownership. They operate as separate brands with separate headquarters, design teams, and product lines. GROHE remains positioned as a premium German-engineered brand for faucets and showers, while American Standard is positioned as a mainstream American brand focused on toilets and value faucets. Lixil also owns other brands like Inax from Japan. So Grohe is not owned by American Standard, but both are owned by Lixil, making them corporate siblings under Japanese ownership.
