Marmox Shower Underlay Centre Drain

The Marmox Shower Underlay Centre Drain System is an innovative solution designed to elevate modern bathroom construction. Perfect for wet rooms, compact bathrooms, and custom shower layouts, this versatile tray system can be easily cut on-site to suit any space—including irregular or circular designs—giving you complete creative freedom.

Constructed from a high-performance polymeric cement core and reinforced with alkaline-resistant glass mesh, this shower underlay is both durable and lightweight, making installation faster and more efficient. The system is inherently waterproof*, providing a reliable base for tiled shower floors while supporting a wide range of tile styles, including smaller tiles from 100mm.

The centre drain configuration ensures balanced water flow from all directions, making it an ideal choice for symmetrical bathroom designs and open-plan wet areas.

Note: Waterproofing over this system is strongly recommended to ensure compliance with Australian Standards.
