Stone-effect LVT has the look of slate, marble and concrete without the cold, hard feel or the sealing that real stone needs. It’s 100% waterproof and works over underfloor heating, which makes it a practical choice for kitchens, bathrooms and hallways.Luvanto stone comes in 305 x 610mm and 305 x 305mm tiles, glue-down or click, and the glue-down tiles can be laid with Design Strips to create grout lines. Craftsman adds a dark grey click tile.
