The short answer is, "No." The longer answer is a little more complicated.
Hansgrohe is the original company founded in Germany by Hans Grohe in 1901. Grohe had been a well-known clothier near Berlin, but his interest in water and early sanitation systems led him to abandon fabric and establish a metal-working shop, according to the company's website.
At the turn of the 20th century, indoor plumbing was still a rare convenience in most homes, but Hans saw the potential. He designed tin showers as a more economical way to bathe than the traditional bathtub.
Eventually, Hans was considered a pioneer and expert in shower technologies. Showers today with a wallbar for their handheld showerhead have Grohe to thank for it; he invented it in 1953.
The company is now part of the MASCO Group - headquartered in Atlanta, GA - along with well-known brands like Delta Faucets and Brizo Faucets, but still has members of the Grohe family on board in a variety of roles like heading up the Axor brand and as deputy chairman of the board.
A few years ago, the Hansgrohe slogan was, "Das Orginal," a clear message about its position as the original Grohe company.
Grohe was founded in 1911 as Berkenhoff & Paschedag in Hemer, Germany, but got its new name in 1948, 12 years after Friedrich Grohe, one of Hans Grohe's sons, purchased the company, the company history page reads. From that point, Friederich acquired a number of smaller companies, each of them specializing in a different technology:
- 1956 - Carl Nestler Armaturenfabrik, inventor and leading manufacturer of thermostats
- 1991 - Eichelberg, the oldest (1817) sanitary faucet manufacturer in Germany
- 1994 - Deutsche Armaturenfabrik Leipzig (DAL), inventors of the flush valve
Since then, Grohe has grown and now directly competes against Hansgrohe. Grohe America is headquartered in Bloomingdale, IL.
The two companies do have something in common: both produce quality fixtures; modern and top-of-class for everything from kitchen and bath faucets to rain shower heads and tub faucets.
