What are Marmox shower niches?

Marmox Prefabricated Shower Niches are factory-built, fully waterproofed XPS-cored niche boxes that fit into wall framing. They eliminate the need to site-build and waterproof niche cavities, saving hours of waterproofing detail work per shower.

How are they installed?

Fix into the wall stud cavity at the desired height, screw the flange to the studs, then waterproof the niche-to-wall flange using ACTFLEX 906 WPU or similar liquid membrane. Tile the niche interior using standard tile adhesive.

Are they pre-waterproofed?

Yes. The XPS core is closed-cell and waterproof, and the polymer-modified cement coating bonds directly to waterproofing membranes. You still need to seal the perimeter flange to the surrounding wall membrane.

What sizes are available?

Marmox niches are available in multiple standard sizes including double-shelf options. Refer to the variant selector for current sizing and shelf configurations.

Are they compliant with AS3740?

Yes. When installed per the manufacturer's instructions and integrated with a compliant wet-area waterproofing membrane (ACTFLEX or equivalent), the niche assembly meets AS3740:2021 requirements for wet area waterproofing.
