What is wall return trim and when is it used?

• A. A decorative tile insert.
• B. A trim piece that returns around corners or edges to provide a clean edge and protect tile edges.
• C. A type of adhesive.
• D. A sealant used at joints.

Answer: (B)

Wall return trim is a finishing profile that turns back toward the wall from the edge of the tile. It finishes the exposed edge of a tile run, creating a clean edge and protecting the tile edge from chipping where tile ends meet a wall or corner. This trim is ideal for areas like shower surrounds, backsplashes, or any place a tile edge would otherwise be exposed, because the return leg gives a neat transition and helps keep moisture and wear away from the vulnerable edge. Decorative tile inserts sit within the tile field rather than finish the edge, adhesives bond tiles to the substrate, and sealants fill joints; none of these serve as a finishing edge like wall return trim.
