There’s nothing like the crackle and warmth of an outdoor fire that will make anyone want to build a fire pit in their yard. Luckily, it’s not a hard task. Once you find the spot you want to make your fires, all you need is a fire pit ring insert to contain the flames.

Fire pit ring inserts (also called liners) are crucial elements to any outdoor brick or stone fire pit. Not to be confused with a fire pit ring, inserts are fireproof frameworks that contain your flames for a safe burn in their below-ground shallow hole.

Sunnydaze Fire Pit Ring

Made of thick, unpainted carbon steel, the SunnyDaze fire pit ring is almost twice as deep as most other inserts on the market. The practical 36-inch exterior is just right for typical backyard fire pits, leaving a 30-inch interior diameter big enough to burn even robust, hand-split logs. The steel framing lets you enjoy a raging fire without potentially dangerous tall flames reaching too high into the air.

“We purchased the ring to go inside a cottage block ring that is three stones high,” writes verified purchaser, Mayra Olivas-Arreola. “It worked great. The lip on the outside helps stabilize the ring and keeps it sturdy for the rest of the construction. The width of the hole is perfect for a backyard fire pit, and we get six lawn chairs around the ring comfortably.”


  • Has an average of 4.5 out of five stars
  • Includes an added safety lip
  • 36-inch exterior and 30-inch interior diameters
  • Has an open bottom

What to Consider When Buying a Fire Pit Ring Insert

Fire pit ring inserts are not just outdoor fireplace accessories, they’re stylish fire pit safety devices. Your top priority when buying a fire pit ring insert is to choose one that contains heat-resistant metal materials, which act as a barrier to keep the intense heat and flames from damaging your masonry walls. By not adding a fire pit ring insert, the mortar and adhesives responsible for keeping your fire pit blocks together can weaken over time due to consistent exposure to heat.

The next consideration is the metal thickness, which is responsible for the durability and protection of the masonry component against heat. Most fire pit ring inserts will include 10- to 20-gauge metal thickness. The thickness you need depends on if you have a small or large fire pit ring.

Types of Fire Pit Ring Inserts

The various types of fire pit ring inserts can be broken down into two categories: shape and bottom.

  • Shape: Fire pit ring inserts come in a variety of shapes. Choose from a circular, rectangle, square or octagon to show personality and add flair to your outdoor fire pit.
  • Bottom: Some fire pit rings are made with a bottom while others aren’t. If you opt for a bottomless fire pit ring insert, you will need to layer the bottom with wood, brick or stone materials.

Do I need a fire pit ring insert?

If you already have one of the best outdoor gas fire pits or rely on an outdoor fireplace, you don’t need a fire pit ring insert. However, if you’re planning to build a fire pit in your yard or patio area, a fire pit insert is a smart backyard fire pit idea. Putting an insert in your DIY fire pit helps to contain the flames and sparks while also preserving the stonework from the effects of long heat exposure.

What do you put under a fire pit ring?

Some fire pit rings are made with a metal bottom while others are bottomless. If your fire pit ring insert falls into the latter category, you can layer the bottom of your insert with brick or patio stone, or layer wood on the ground to burn inside the insert. If you choose the wood option, know that your landscape may take several years to recover from the heat and burning.

What is the best material for a fire pit ring?

Fire pit rings made of metal materials, such as steel or iron, are best for a fire pit insert. They’re very strong and durable, and have a strong threshold to withstand the heat.
