How to Choose the Right Outdoor Fireplace Kit

Choosing the right outdoor fireplace kit starts with scale, sightlines, and how people will gather around the fire. Use the comparison below to see how compact, standard, see-through, and TV-ready fireplace kits relate in height, width, footprint, and overall presence.

Compare fireplace kit sizes, footprints, and proportions before choosing the right model for your patio, pool area, outdoor kitchen, or backyard living space.

Compact, Standard, See-Through, and TV-Ready Fireplace Kits

A compact outdoor fireplace kit works well for smaller patios, courtyards, and tighter backyard spaces where the fireplace should feel permanent without overwhelming the seating area. A larger masonry fireplace kit creates more visual weight and works better as the main focal point for a full backyard living room, poolside lounge, or outdoor kitchen.

The layout matters, too. A standard outdoor fireplace kit creates a classic one-sided focal point for seating areas, patios, and outdoor rooms. A see-through outdoor fireplace kit can divide two outdoor spaces while keeping the area open and connected. A TV-ready fireplace kit can turn a patio or covered outdoor space into a complete outdoor living room. Choose the fireplace model that fits how people will sit, move, relax, entertain, and gather around the fire.

DIY-Friendly Outdoor Fireplace Kits, Without the Guesswork

Building an outdoor fireplace from scratch usually means hiring a mason, sourcing block and firebrick, figuring out dimensions, ordering caps and veneer, and hoping every part of the design works together once installation begins.

Cornerstone fireplace kits simplify the process of building an outdoor fireplace. The major masonry components are selected, sized, and packaged as a complete kit, giving you a clearer path from planning to finished installation. Each wood-burning outdoor fireplace kit is designed around a firebrick-lined firebox and solid masonry components. You still get the substance of a stone outdoor fireplace, but without having to design every course, cut list, and component from a blank page.

For experienced DIY homeowners, that means a fireplace project that is much more manageable. For contractors, it means a repeatable system that helps reduce layout time, sourcing headaches, and design uncertainty. Either way, the goal is the same: a better outdoor fireplace with fewer moving parts.

If an 82-Year-Old Can Build It, So Can You

Meet Jim, a homeowner who built his Cornerstone fireplace kit at 82.

His project shows why a guided, mortarless fireplace kit can be much more approachable than scratch-built masonry. With a clear layout, solid components, and some help with moving materials into place, the build becomes a step-by-step project rather than a custom masonry puzzle.

Outdoor Fireplace Kits Guide: Types, Differences & What to Know

Outdoor Fireplace Kits vs. Scratch-Built or Lightweight Fireplaces

There are three common ways to add an outdoor fireplace: build it from scratch, buy a lightweight veneer unit, or use our complete masonry fireplace kit.

Scratch-built masonry gives you the most flexibility, but it usually requires more design work, more skilled labor, more sourcing, and more uncertainty in the final price. Lightweight prefab fireplaces often lack the mass, permanence, or architectural presence of a solid masonry feature, and they require expensive veneers that are difficult to install properly.

Cornerstone gives you a solid middle path: a real masonry outdoor fireplace kit with a more guided, predictable installation process. You build with the look and mass of stone masonry, but with a system designed to help homeowners and contractors move from idea to installation more smoothly.

FeatureCornerstone Masonry SystemStandard Veneer Kits
Structure8″ thick solid masonry blocksHollow metal or wood frame
FacadeIntegrated tumbled stone lookAdhered thin stone or veneer
AssemblyMortarless dry-stack systemFrame, lath, adhesive, and veneer steps
DurabilitySolid masonry constructionDependent on frame, veneer, and installation quality
AccentsGenuine Indiana limestoneCast concrete or manufactured stone options

Unlike traditional veneer kits that require a separate frame, adhered stone, and additional installation steps, the Cornerstone system uses the structural masonry blocks themselves as the finished facade. That all-in-one approach reduces the need for extra materials and installation steps while delivering the authentic weight and texture of hand-laid stone.

Kit Building Progression to Patio

The Cornerstone System, Endless Possibilities.

Why build temporary when you can build permanent? Our kits utilize a mortarless masonry system that locks together with a precision fit, eliminating the saws and mess of traditional construction. It’s a unified approach to outdoor living: start with a grill island, add a custom fire pit, or anchor your patio with a grand masonry fireplace. Everything we build is designed to work together, giving you the freedom to scale your backyard retreat on a rock-solid, professional-grade foundation.

Common Questions About Outdoor Fireplace Kits

Yes. The firebox and chimney system is designed specifically for wood-burning use and adheres to proven masonry fireplace principles when installed as shown in the instructions. Every kit is designed for safe wood-burning use and includes a fire brick-lined firebox, deep hearth, and a stainless-steel spark arrestor for added peace of mind.

These fireplaces are built from structural masonry units, not surface veneer. The stone is part of the structure itself, not a decorative layer applied over framing.

No. The system is designed for no-cut assembly using standard tools. The blocks stack and bond together without sawing or specialized masonry equipment.

Yes. The kits are engineered so homeowners can assemble them confidently using clear instructions, dimensions, and planning resources provided before and after purchase.

Outdoor fireplace kits can be installed on patios, slabs, or properly prepared bases. Placement depends on site conditions, clearances, and local codes.

Your fireplace should be installed on a proper footing or an existing patio that can support the weight of a masonry structure.Yes. Like all masonry-style structures, your fireplace requires a stable foundation. Many installations use an existing concrete slab. Many people use a crushed aggregate (paver) base, while others may require a small footing depending on soil conditions and local requirements.

Yes. The modular system allows for layout adjustments and optional components so the fireplace can be tailored to your space and design goals. While most kits feature the same size firebox, we do offer two-sided and compact firebox kits to ensure you get the size fireplace your home needs. Wood storage boxes, chimney extensions and more are available for all our fireplace kits.

When installed properly, these fireplaces are built to last for decades. The masonry construction is designed for long-term outdoor use with minimal maintenance.

For many homeowners, an outdoor fireplace becomes a long-term focal point for gathering, warmth, and everyday use. Compared to a fire pit, a masonry fireplace provides directed heat, wind protection, and a more permanent presence within the overall outdoor living space.
