A system warranty is a comprehensive warranty that includes all products in a particular system of Schluter products (e.g., Schluter®-Shower System, Schluter®-DITRA-HEAT, Schluter®-DITRA). If there is an issue, these system warranties cover the reinstallation/replacement of the Schluter products, non-reusable tile surfaces, and the appropriate setting and grouting materials or payment to reinstall the affected portion of the tile assembly, including labor. Depending on the system(s), our warranties can last from 10 years to lifetime. Schluter offers a lifetime extended limited warranty that is available when applicable Schluter systems are used with Schluter thin-set mortars.
