Product Options:


A Marmox Niche is an elegant way to provide extra space for small shower items. Providing a low-cost, easy to install and completely waterproof option.

These shower niches are comprised of an extruded polystyrene core, coated on either side with a thin but robust layer of fibreglass mesh & reinforced polymer concrete.

Marmox Shower Niches are fixed to the wall, usually on a frame, so that the front lip of the niche is flush with the Marmox Multiboard on the wall. The joints between the shower niche and the Multiboard are sealed together with Marmox Waterproof Tape.
