Ensuring Safety with Every Outdoor Fireplace Kit Design

Your fireplace kit has been designed up to a standard of excellence and safety. We don’t design down to a price point. From heavy angle irons, deep mantels and hearths, and stone appearance, see what we include in our kits that other companies ignore or charge more for.

Stainless Steel Spark Arrestor

Stainless Steel Spark Arrestor

Your safety is our top priority. Therefore, we include a spark arrestor with every kit. This addition will help prevent wildfires. It is much safer than a 100-plus pound stone found on other kits. Large stones don’t block floating embers from starting fires. Moreover, they are dangerous to install. We eliminate both problems with the best US-made spark arrestor available.

Designed for Safety: Large Hearth and Mantel

Can you believe some brands charge over a thousand bucks for a hearth? Hearths are needed to catch popping embers or if a fiery log rolls out of the firebox. Of course, our hearth comes included. Per best practices, we design all our fireplaces with a deep 12-16″ hearth for safety. Add a screen in your style for extended safety.

Performative Firebox: Efficiency Meets Design

Our wide firebox kit dimensions help produce great draft and heating efficiency. The opening is wide to allow ample room for your fire while not being overly wide and inefficient. Firebricks add heat retention and longevity. Not likely needed in a lifetime, but the firebrick is a liner that can be replaced and protects the walls of your fireplace.

Customize Your Outdoor Fireplace Kit to Fit Your Backyard Needs

Getting what you want is simple.  First, you choose your outdoor fireplace’s color, followed by its style or shape. You can choose between a standard firebox or a see-through firebox. All our fireplace kits are large premium kits. Once you have chosen the model of your outdoor fireplace kit, customize it with add-ons and packages. We are adding more options all the time. The styles aren’t endless, but there is more than enough to build a custom outdoor fireplace for your dream backyard.

Choose from Four Outdoor Fireplace Kits- Then Customize to Your Taste

The Barrington model is the most traditional fireplace design. You may want to choose a Bremley fireplace for a more modern style. Or, if you can’t miss the big game, opt for our Bremley TV edition. All models feature the same large 36″ firebox, as well as a large hearth and built-in mantel, except the Ashford. The Ashford is a compact fireplace that comes with firewood boxes included.
