Move over granite, quartz, and marble — lava stone countertops are one of the hottest (sometimes literally) new trends in kitchen design. Made volcanic rock that has been cut into slabs and fired with an enamel glaze, lava stone countertops are incredibly durable, more sustainable than other materials, and versatile for both indoor and outdoor use.
* Temperature resistance. Lava stone is very resistant to heat, cold, and temperature swings, and you can place hot pans directly on the surface. Granite sealant and quartz are both sensitive to excessive heat, while rapid fluctuations can crack quartz and marble.
* Porosity. Lava stone's enameled surface is nonporous, so it won't harbor bacteria and it resists staining, unlike marble or unsealed granite.
* Durability. UV rays can fade or discolor marble, quartz, and granite countertops over time, and none of these materials are generally recommended for outdoor surfaces. The enamel finish on lava rock does not fade with UV exposure, can withstand caustic chemicals (a major no-no on other stone surfaces) and resists chipping and cracking.
* Color. Lava rock's enamel finish comes in a huge array of colors, and the slight irregularities all along the surface make each countertop a unique piece.
The main downside to lava rock countertops: Cost. It's among the most expensive options available at around $250 to $350 per square foot, while marble often comes in at about $100 per square foot. For a more budget-friendly alternative, sealed porcelain countertops range from about $50 to $120 per square foot. Many colors and patterns are available, and while it won't hold up quite like lava stone, it's still durable and heat-resistant with an on-trend glossy finish.
