Carenza Bianca Matte Marble Look Bullnose Porcelain Trim 4x12

Carenza Bianca is a 4x12 matte porcelain bullnose trim piece with a light gray marble look crossed by pewter-colored veins. It carries the cooler Bianca coloring found throughout the Carenza line, allowing an exposed end to continue the same visual language as the coordinating field tile and mosaics. V3 variation introduces noticeable tonal and veining differences between pieces.

The 4x12 proportions create an elongated border rather than a small accent, while the matte surface keeps reflected light restrained. Its bullnose profile forms a finished boundary along matching tile runs, and the rectified edge maintains a precisely cut outline where the trim meets neighboring material. At 9 mm, or 3/8 inch, thick, it shares the thickness specified for the coordinating Carenza formats.

Water absorption is 0.5% or less, qualifying the porcelain body as impervious under ANSI A137.1 and indicating that it takes up almost no water. Breaking strength reaches at least 425 pounds, compared with the 250-pound ANSI benchmark referenced for floor tile. The trim is resistant to frost and thermal shock, two separate measures of response to temperature conditions.

This bullnose is sold by the piece. Each box contains 15 pieces and weighs 22 pounds. Coordinating Bianca choices include 12x24 and 24x48 field tile and a 2x2 mosaic. The same 4x12 trim is also available in Oro matte.
