With all the energy of an erupting volcano, the shades of fire and ice collide with a burst color in our Volcanic Peak tiles. Make a statement in any room with a combination of four colors: dark red, light blue, medium blue, and white and red swirled frosted glass. At 23 mm (almost 1 inch), these square tiles are beautiful as well as functional, and because they are nonskid, they can work effectively on any surface.
