The Uni-Green Square Niche is an essential component for any bathroom renovation focused on long-term reliability. It is injection-molded from high-impact ABS with a 4mm wall thickness, making it much more rigid than standard plastic inserts. This one-piece design effectively removes the risk of leaks at the bottom corners, which are the most common failure points in hand-built shower niches.
One of the key engineering features is the 1-degree pitch on the bottom shelf, which uses gravity to ensure water runs off and doesn't pool. The interior surface has a textured "honeycomb" grid designed to help thin-set mortar stick firmly, ensuring your tile job looks professional and stays secure. Because it is a "set-and-forget" unit, it can reduce the time needed to install a shower niche from several hours down to about 20 minutes.
While the square design is efficient for storage, it is helpful to feather out the mortar 6 to 8 inches beyond the outer flange during installation. This helps hide the transition between the niche and the wallboard, ensuring the finished tile wall is perfectly flat. This unit is a practical, durable choice for those prioritizing function and waterproofing over complex designs.
For a more decorative and modern look that doesn't require tiling, the Black Stainless Steel Niche provides a sleek alternative. See more square and rectangular inserts by visiting built-in shower niche organizers.
