Stetra Corners

DESCRIPTION
Stetra Corners are prefabricated waterproof components designed for 90° internal and external joints, made of reinforced polymer membrane. The seamless monolithic design ensures perfect water tightness, while the thin profile minimizes bulk at corners.
Their material flexibility allows easy adaptation even in imperfect corners and ensures a secure seal—ideal for preventing leaks and mold formation.

APPLICATION
Stetra Corners are designed to seal wall-to-floor and wall-to-wall junctions in waterproofing systems. Ideal for:
● showers, bathrooms, and spas;
● external corners in niches or around columns;
● edges in ventilated walls;
● complex shower tray details.
Installation is quick and safe thanks to the preformed geometry: apply the main membrane, overlap the Stetra Corner by at least 5 cm, and embed it in adhesive. This creates a durable, watertight system in line with best waterproofing practices.
