Our Hudson Penny Round Stillwater Porcelain Mosaic Tile is a beautifully tranquil update on the timeless penny round design. Featuring a reactive glaze with an eye-drop effect, these tiles have varying shades of grey, ranging from slate grey to a dark cloudy grey, that blend to white on the edges. This mosaic creates a uniquely sporadic design through a pleasing mixture of cool-toned tints with additional dimension added by the smooth, high-gloss finish. Its impervious and frost-resistant features make this penny tile an ideal choice for indoor and outdoor floor and wall installations including, kitchen backsplashes, bathroom showers and accent walls. This penny round tile can be used as a whole sheet or cut into smaller strips as an accent piece. It is a perfect choice on its own or coordinated with other colors in our Hudson Penny Round series. Color: Stillwater; High Sheen.
