Hair caught in the drain? The structural self-cleaning function of Schlüter-KERDI-LINE-VARIO makes that a rare occurrence. To rule out any drain clogging, we offer an additional hair trap. It catches hair and other small parts, which can be especially useful for those wearing jewellery in the shower. Schlüter-KERDI-LINE-VARIO-S is compatible with the WAVE 42 and Cove 34 drainage profiles.
