Do Gas Grills Need Lava Rocks?

Most gas grills come with a lava rock tray already installed. If your grill didn’t come with one, or if you’ve lost it, you can purchase one at a home improvement store. Lava rocks help distribute the heat evenly across the cooking surface and prevent flare-ups.

They also add flavor to your food by absorbing drippings and vaporizing them.

If you’re like most people, you probably think that all grills need lava rocks. After all, they help to distribute the heat and prevent flare-ups, right? Well, it turns out that gas grills don’t actually need lava rocks.

In fact, many experts believe that they can actually do more harm than good. Lava rocks are made of porous materials like pumice or obsidian. When heated, these materials release gases that can be harmful to your health.

Additionally, lava rocks can absorb grease and other liquids, which can cause them to explode when heated. For these reasons, it’s generally best to avoid using lava rocks on your gas grill.

-How Often Should I Replace My Lava Rocks

Lava rocks are a type of igneous rock that forms when molten lava cools and hardens. They are commonly used in landscaping and gardening, as well as in aquariums and fish tanks. Lava rocks are very durable and last for many years, but they will eventually need to be replaced.

Depending on the size of your lava rocks and how often they are used, you may need to replace them every few years or so. If you notice that your lava rocks are starting to break down or crumble, it’s time to replace them.


Most gas grills come with a layer of lava rocks or briquettes. These rocks help to distribute the heat evenly across the grill and prevent flare-ups. Many people wonder if they really need to use lava rocks or if they can just use charcoal.

Lava rocks are not necessary for your gas grill, but they can certainly be helpful. If you do choose to use them, make sure that you soak them in water for at least an hour before grilling. This will help to prevent them from igniting and causing a fire.
