Schluter Kerdi-Drain Classic Shower Grate Kit KD4GRKE – 4-inch Square Stainless Grate

Overview

The Schluter Kerdi-Drain Classic Shower Grate Kit KD4GRKE is designed for tile showers that value both performance and a clean, contemporary look. The 4‑inch square stainless steel grate sits atop a drain body built to work with Schluter’s Kerdi waterproofing membrane, supporting a cohesive, moisture-conscious shower installation.

Why this kit stands out

This drain system combines practical engineering with a refined finish, aiming to streamline installation and daily upkeep. The integrated bonding flange creates a secure connection with the Kerdi membrane, helping water move efficiently away from grout lines while maintaining a slim, modern profile. The stainless steel grate resists daily moisture, offering a durable surface that complements chrome and brushed fixtures alike.

• Secure waterproofing: integrated bonding flange ensures a reliable link to the Kerdi membrane for effective moisture management.
• Versatile compatibility: designed to integrate with a variety of shower systems and tile configurations.
• Low maintenance: the grate is removable for straightforward cleaning of the drain housing and pipes.
• Built to last: constructed from high-quality stainless steel to withstand daily shower use.
• Long-term coverage: backed by a 10-year limited warranty when installed per Schluter's guidelines and data sheets.

In real-world showers, this setup can help maintain a neat, water-resistant boundary around the tile edges while preserving a sleek aesthetic. It’s a practical option for both practical family bathrooms and higher-end shower spaces where a refined finish matters.
