Making better homes a reality for everyone, everywhere

Every person on the planet dreams a better home. LIXIL makes that possible with pioneering water and housing products. Through the merger of five of Japan's most successful building materials and housing companies, we draw on our Japanese heritage to create world-leading technology and high-quality products that transform homes. We make things that matter to all sorts of different people, to the many communities we are part of, and to sustainably support the world we live in. Today, our approach comes to life through some of the most trusted global brands in our industry, including INAX, GROHE, American Standard, and TOSTEM. We are proud that our products touch the lives of more than a billion people every day, but believe we have the potential to still do so much more.
