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.

Large Hearth and Mantel
Standard Fireplace Hearth

Performative Firebox: Efficiency Meets Design

Our wide firebox 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.

Cornerstone Outdoor Fireplaces are Affordable Luxury for Every Backyard

Do you love the crackle and warmth of a real wood fire? Are you looking to add a wood-burning hardscape feature to our backyard? Perhaps you carve the ease of a gas-fired fireplace.

Why buy our DIY kits when creating your outdoor living oasis?

1. You will Save Money with Our Easy-to-Build Kits

Upgrading your home and expanding its useability isn’t just a monetary investment; it’s an investment in well-being. Moreover, you’ll recoup your investment when you sell your property.

4. You won’t need skilled labor installing our easy-to-build kits

You deserve a fantastic personal space to relax and recharge. Moreover, you deserve a rockin’ pad to throw parties and entertain guests. You also know how many hours procuring a rockin’ pad can take. Spend time enjoying your killer patio- not building it. Most of our DIY kits can be built in a weekend or less. You don’t need special tools or skills- our kits are fun and easy to build.
