Transform that unused bathroom corner into a luxury oasis with the Inster 36" x 36" Double Threshold Shower Base. Whether you’re embarking on a full-scale renovation or just upgrading your guest bath, this square corner pan provides the perfect modern foundation. Its double threshold design is tailor-made for those seeking a bright, airy shower space with glass walls on two sides.Engineered for Performance At Inster, we know that a shower base is only as good as its construction. That’s why our trays are built using a high-performance Acrylic and ABS composite. This material offers the brilliant, reflective white finish of porcelain but with the impact resistance and warmth of modern polymers. It won’t creak, it won’t flex, and it certainly won’t yellow over time.
