Marmox Trough Underlay 1200X1200 Long Grate Mmt-T1212L
Marmox Shower Underlay Long Grate
The Marmox Shower Underlay Long Grate System is a modern drainage solution designed for sleek, contemporary bathrooms and wet rooms. Featuring a linear (long grate) drain design, this system creates a minimalist, high-end finish while delivering efficient water flow—ideal for open-plan showers and larger tiled areas.
Built from a durable yet lightweight polymeric cement core, and reinforced with alkaline-resistant glass mesh, the Marmox underlay provides a strong, stable, and tile-ready base. The tray is pre-formed with a precise gradient to direct water efficiently toward the linear drain, ensuring optimal drainage performance.
Designed with flexibility in mind, the underlay can be cut to size on-site, allowing it to suit a wide range of layouts—including custom and irregular shower spaces. Its low-profile design also enables step-free access, making it perfect for modern and accessible bathroom designs.
Note: Waterproofing over this system is strongly recommended to comply with Australian Standards.
