Acrylic niche trims are prefabricated, water-resistant framing components designed to neatly seal and finish the raw outer edges of a tiled shower niche. Crafted from durable, lightweight acrylic, these trims create a smooth, non-porous border that shields the wall cavity from moisture infiltration and conceals rough tile cuts. Their low-profile design provides a clean, modern aesthetic that blends seamlessly into surrounding tilework while resisting mold, mildew, and soap scum buildup. Because they require no complex miter cutting or specialized maintenance, acrylic niche trims offer an efficient, stylish solution for achieving a polished, professional finish in wet environments.
