Building a Round Fire Pit with Bricks: DIY Guide

A round fire pit made from bricks can be a charming addition to your outdoor space, providing warmth, ambiance, and an inviting focal point for gatherings. Bricks are an excellent choice for fire pits as they can withstand high temperatures, are durable, and add rustic charm to any setting.

But how do you go about building this charming feature? Let's explore the world of round fire pit construction using bricks, from planning to completion.

Design Considerations

Before you start gathering materials, you need to plan the design of your fire pit. The size is crucial, as it determines the scale of your project and the materials needed. Typically, fire pits range from 36 to 48 inches in diameter, providing ample space for seating and conversation.

Consider the height as well. The average height for a fire pit is around 18 inches, but you may want to adjust this based on your seating arrangements and the desired visual impact.

Choosing the Perfect Location

Safety is paramount when it comes to fire pits. You should situate your fire pit at least 25 feet away from trees, bushes, or other flammable materials. Additionally, ensure it's downwind from structures to prevent smoke from accumulating.

Level ground is ideal for fire pit installation to prevent drainage issues and instability. You may need to prepare the site by removing sod, leveling the ground, and adding a base material, like gravel or sand.

Selecting the Right Bricks

When selecting bricks, longevity and aesthetics should be your guide. Fire bricks, made from refractory materials, are an ideal choice due to their high heat resistance. However, regular concrete bricks or clay bricks can also be used, as long as they're heat-tolerant and of uniform size.

For a more professional look, consider using fire pit kits that come with pre-cut bricks designed specifically for fire pits. These ensure a seamless, aesthetically pleasing finish.

Construction Steps

Building a round fire pit with bricks involves several steps, from laying the foundation to completing the final layers. Here's a simplified guide to help you through the process:

Before you start, make sure you have all necessary tools and materials, including bricks, mortar, trowel, measuring tape, rubber mallet, shovel, level, and gloves. You'll also need fireproofing materials, such as sand or lava rock, to line the inner layer of the fire pit.

Laying the Base

Begin by preparing the base of your fire pit. Dig down about 4 inches deeper than the desired height of your fire pit, leaving an additional 2 inches for gravel and mortar. Fill this area with a layer of gravel for drainage, then cover it with a layer of sand or mortar.

Use a trowel to smooth out the sand or mortar, ensuring it's level. This will provide a stable base for your fire pit and prevent water from seeping into the brick joint.

Constructing the Fire Pit Walls

Start at the center and work your way out, using a spiral pattern tolay the bricks. Apply mortar to the bottom of each brick using a notched trowel, then place it in position. Tap it gently with a rubber mallet to set it firmly in place.

Leave joints between bricks for expansion and contraction. When you reach the desired height, allow the mortar to cure according to the manufacturer's instructions.

Finishing Touches and Safety Measures

Once the mortar has cured, you can add a layer of fire-resistant material on the inside of the fire pit. This could be sand, lava rock, or even a metal grate. This adds a layer of safety, preventing sparks and embers from escaping.

Finally, add a layer of gravel or decorative stone around the base of your fire pit for a finished look. This also helps with drainage and prevents water from pooling and eroding the base of your fire pit.

Your round fire pit with bricks is now ready for enjoyment. Remember to always use caution when starting and maintaining a fire, and never leave your fire pit unattended. With proper care, your brick fire pit can provide warmth and enjoyment for years to come.
