You get a limited warranty with each of Hansgrohe’s products. All products purchased from an authorized retailer come with a five-year guarantee from the manufacturer.
Because the warranty cannot be transferred to another person, it is only valid for the first purchaser of the device and only in the location where it was initially installed.
Hansgrohe offers a replacement of the product or the component in question if you discover flaws in either the materials used or the craftsmanship of the item.
