Kolorines Vitrogota Pebble collection reflects the design of natural river pebbles. The flat shape gives a smooth, comfortable walking surface, while the color options of the glass mosaic pebbles far exceeds those found in rivers. The glass pebbles come pre-assembled in interlocking sheets for easy installation. There are four size variations per sheet. This tile is the perfect choice for your swimming pool and spa and home interior and exterior, wet or dry installations, including kitchen backsplashes, shower walls and residential floors (not slip resistant).
