Many of the new porcelain tiles for showers or walls do not come with a prefabricated finished trim piece (bullnose) to trim the edge of a tile shower wall, niche, or curb. This leaves a few options for trim, such as a Schluter Jolly (A100) or similar or doing a mitered edge. One of the drawbacks of a mitered tile edge is that they can be fragile on the corner or sharp. In an area such as a shower where slipping or stepping on a corner is a possibility, this Schluter Finec profile is great because it combines the clean look of a mitered joint with the protection and safety of a metal edge trim.
