Top How Deep Should A Inground Fire Pit Be? Idea. We built our fire pit with a patio surround, so you'll need to apply the same steps for building a paver patio. If your fire pit is too tall, you won't be able to prop your feet comfortably on the edge. Make sure the ground is as level as possible before adding in your layer of lava rocks or fire pit glass.

If you decide to dig a deeper fire pit, make sure you have some kind of ventilation so your fire gets enough air to burn.
You can go deeper if you want, but keep in mind that you don't want the hole so deep you can't enjoy watching the fire. On places like decks or hills that may be more of a pain to try to contour to fit an inground fire pit. Make sure the ground is as level as possible before adding in your layer of lava rocks or fire pit glass. I was wondering if there is a difference between drilling many small vent holes (1.25 inch drill bit) or making 2 large vent holes (busting a few blocks out). The fire will rest above that. To build a backyard fire pit with bricks, start by digging a circular hole that's 4 feet in diameter and 12 inches deep. Dig a eight inch wide hole below the rest of the fire pit about twelve inches deep and fill with gravel. Besides thinking about the safety and legal aspects of owning a fire pit, you'll probably also wonder what size fire pit you need and how deep the pit should be. You should only use a solid cover when you are ready to extinguish the fire.
