Square Gas Fire Bowls

Square gas fire bowls from The Outdoor Plus and Fire by Design. A square fire bowl gives a crisp, architectural outline that lines up with modern paving, pool edges and planters. Browse copper, concrete, powder coat and GFRC designs in a range of sizes, offered for natural gas or liquid propane.

Why Choose a Square Fire Bowl?

Square bowls suit contemporary spaces. Their straight edges line up with pool coping, steps and walls, so a row of square bowls looks precise and planned. The flame still rises from the center, but the square form gives a stronger, more structured look than a round bowl.

Designs in This Collection

• The Outdoor Plus – the Maya square fire bowl, offered in concrete, powder coat and copper in 24", 30" and 36" sizes.

Where Fire Bowls Work Best

Fire bowls are compact, so they fit where a full fire pit won't. Line a pool edge with a row of bowls, frame an entrance or a set of steps with a matching pair, or set a single bowl on a low wall or plinth as a focal point in the garden. Several bowls in a row create rhythm and light along a long space, and a pair on either side of a feature creates symmetry. Some fire bowls can also be combined with water features, and our fire and water features collection shows designs made for that.

Choosing the Right Size

Think about how far the bowl will be seen from. A large bowl reads well across a big pool or lawn, while smaller bowls suit tighter spaces and work well in groups. Check the bowl's height too: a low bowl suits a plinth or wall, while a taller bowl can stand on its own. Each product page lists the dimensions published by the manufacturer.

Materials and Finishes

Copper brings a warm, handcrafted look. Powder coat offers a range of colors with a durable baked-on finish. Concrete and GFRC bowls give a solid, architectural presence and come in a range of colors to match stone, paving and pool coping.

Plan the Gas Supply First

Every gas fire feature has a BTU rating that tells you how much gas the burner needs to reach its full flame. Pipe diameter, the length of the run from the meter or tank, and the number of fittings all affect how much gas reaches the burner, and an undersized line is the most common reason a fire feature never reaches its full flame height. Share the BTU rating listed on the product page with your gas professional so they can confirm the line size before installation.

Choosing an Ignition System

Many products in this collection are offered with a choice of ignition. Match lit systems are the simplest and need no electricity. Flame sense systems add a safety valve that shuts off the gas if the flame goes out, and spark ignition lets you light the fire with a push of a button. Electronic ignition lets you control the fire from a switch, timer or home automation system. The available options vary by manufacturer and are listed on each product page.

Natural Gas or Propane

Choose the fuel before you order. Natural gas and liquid propane versions are built with different components and are not interchangeable. Natural gas suits permanent installations close to an existing gas line, while propane runs from a tank and works where there is no gas line. Our Natural Gas vs. Propane guide explains the differences in more detail.

Ventilation and Drainage

Any enclosed gas fire feature needs ventilation so gas cannot collect inside the base. Propane is heavier than air and settles low; natural gas is lighter than air and rises. Follow the vent requirements in the manufacturer's installation instructions and your local code. Rainwater also filters down through the fire media, so make sure there is a path for water to drain away from the burner and gas components.

Finishing With Fire Glass or Lava Rock

Fire media hides the burner, spreads the flame and gives the fire feature its finished look. Fire glass adds color and sparkle, while lava rock gives a natural, rustic look. In a bowl, the media also forms the visible surface, so it plays a big part in the finished look. Cover the burner evenly at the depth recommended in the installation instructions. Shop our fire glass and lava rock, and protect your fire feature between uses with a fire pit cover.

Professional Installation

All gas fire features must be installed by a qualified, locally licensed gas professional, following the manufacturer's installation instructions and your local building codes. Keep the clearances to combustible materials listed in the instructions, and do not place a gas fire feature under an awning, pergola or other overhead structure.
