Winter Stone Glacier Gray Matte Bullnose Porcelain Trim 4x12

Winter Stone Glacier Gray comes as a 4x12 matte porcelain bullnose trim piece shaped around a calm, linear stone look. The gray field has gentle directional character rather than dramatic veining, and the low-sheen finish keeps the surface visually quiet. Within Winter Stone, this soft mineral effect appears in Glacier Gray and Ice White with matte and polished options.

The 9 mm, or 3/8 inch, thickness gives the trim a substantial profile, while rectified edges create clean endpoints for wall sections, exposed edges, and aligned tile runs. Its V2 rating indicates limited shade movement, so neighboring pieces can differ slightly while the overall gray composition remains controlled.

With water absorption at 0.5% or less, the porcelain qualifies as impervious and absorbs almost no moisture through its body. A breaking strength of at least 325 pounds exceeds the 250-pound threshold used for porcelain floor tile. Frost resistance and thermal shock resistance are both present as tested material characteristics.

The bullnose is priced and sold individually; a full box contains 15 pieces and weighs 22 pounds. Glacier Gray continues in 12x24 tile, 24x48 tile, and a 2x2 mosaic. Ice White matte and Ice White polished provide two color-finish alternatives in this 4x12 trim size.
