Winter Stone Glacier Gray Polished Bullnose Porcelain Trim 4x12

Winter Stone Glacier Gray is a 4x12 polished porcelain bullnose trim piece shaped around a calm, linear stone look. The gray coloring reads cool and even, while the polished face catches light across the directional markings. Winter Stone carries this softened stone expression through Glacier Gray and Ice White pieces in reflective or restrained finishes.

At 4x12, the elongated trim completes exposed edges and creates a continuous endpoint for tiled runs, framed sections, or transitions. Its bullnose profile provides the finished curved side, and rectified edges give the piece a precise outline. The 9 mm, or 3/8 inch, thickness matches the dimensions of the coordinated line. A V2 shade rating indicates slight visual differences among pieces, enough for natural movement without pronounced contrast.

The porcelain absorbs 0.5% water or less, placing it in the impervious category under ANSI A137.1 and meaning very little water enters the body. Breaking strength is at least 325 pounds, comfortably above the 250-pound ANSI reference for floor tile. It also records resistance to frost and thermal shock in the corresponding performance tests.

Sold individually, this bullnose is packed 15 pieces per box, with a box weight of 22 pounds. Glacier Gray field tile is offered in 12x24 and 24x48 sizes. The 4x12 bullnose format also comes in Ice White matte and Ice White polished.
