Ivorynn Stone Riverstone Grey Matte Travertine Look Bullnose Porcelain Trim 4x12

Ivorynn Stone Riverstone Grey is a 4x12 matte porcelain bullnose trim piece with a gray travertine look. Digital veining brings layered stone movement to the face, and raised texture traces the pattern so the trim coordinates in both appearance and touch with the larger series pieces.

Its 4x12 proportion forms a narrow finishing course, while the bullnose edge closes exposed tile ends and completes borders and transitions within matching runs. The matte finish maintains subdued reflection beside coordinating surfaces. V4 variation allows noticeable changes in gray tone and veining between pieces, preserving the line's varied stone character. Rectified edges give the trim a precisely formed profile, and its 9 mm, or 3/8 inch, thickness matches the related Riverstone Grey field tiles and mosaics.

Absorption of 0.5% or less qualifies this piece as impervious porcelain, meaning its body takes up almost no water. Breaking strength is at least 425 pounds, above the 250-pound ANSI floor-tile benchmark. The surface measures 7 on the Mohs scale, a hardness that resists scratches from grit and sand. It carries Class E chemical resistance and is resistant to frost and thermal shock.

Pieces are sold individually, with 15 pieces packed in each 22-pound box. Matching Riverstone Grey choices include the 24x48 tile and 2x2 mosaic. The same 4x12 bullnose format is also produced in Sahara Sand matte and Caramel Noce matte.
