Introduction: The Foundation of Every Great Outdoor Kitchen
Outdoor kitchens have evolved into an essential extension of modern living spaces. Whether you’re entertaining guests or preparing a weeknight meal, the outdoor kitchen has become more than just a grill and a side table—it’s a reflection of your lifestyle. However, beneath the luxurious countertops and high-end appliances lies a critical component: the frame.
The galvanized steel and stainless steel Sullivan outdoor kitchen frame offers a strong, weather-resistant foundation designed for long-term durability. If you’re considering installing an outdoor kitchen—whether through a prefab solution or a fully customized build—understanding the differences in materials, costs, installation, and available design tools will help you make the right decision.
In this guide, we explore everything you need to know about these frame systems, from material breakdowns and reviews to blueprints, costs, and DIY options.
Galvanized Steel vs. Stainless Steel: Choosing the Right Material
Selecting the right structural material is one of the most important steps in designing an outdoor kitchen. Galvanized steel and stainless steel are the two leading options for Sullivan outdoor kitchen frames—and for good reason.
Galvanized steel is steel coated with a protective layer of zinc, which helps guard against corrosion. It’s cost-effective and widely used in outdoor construction projects. It’s especially well-suited for dry or moderately humid climates, offering a balance between strength and affordability.
Stainless steel, on the other hand, resists corrosion naturally without the need for coating. Its sleek, modern appearance makes it a favorite for exposed finishes and premium builds. While more expensive, it is ideal for coastal or high-moisture environments due to its superior rust resistance.
Many Sullivan frame systems integrate both materials—using galvanized steel for the internal framework and stainless steel for external surfaces and finishes where exposure to the elements is greatest.
What Homeowners Are Saying: Reviews on Sullivan Outdoor Kitchen Frames
Homeowners who have chosen Sullivan frames consistently highlight the strength and precision of these systems. The modular design is especially appreciated, making it easy to customize the layout to fit a wide range of outdoor spaces. Whether constructing a straight-line grill island or a more complex L- or U-shaped design, users find the assembly to be logical and reliable.
Many also praise the quality of the welds, pre-cut utility ports for gas and water lines, and the frame’s compatibility with a variety of finish materials like tile, stone veneer, and stucco.
DIY users often describe the installation process as intuitive—comparing it to assembling commercial-grade furniture. With detailed blueprints and labeling on each frame section, even non-professionals have successfully completed builds without needing extensive construction experience.
Installation Overview: How to Set Up a Sullivan Frame
Installing a galvanized or stainless steel Sullivan frame involves several phases, but with proper planning, it’s manageable even for ambitious DIYers.
First, a level and solid foundation is essential. Most outdoor kitchens are installed on concrete pads or paver patios. Once the base is prepared, frame components can be laid out and assembled using bolts or, in some cases, welding depending on the model you’ve chosen.
Before enclosing the frame, utility lines for gas, water, and electricity should be installed. Sullivan’s frame systems are typically pre-cut or designed to accommodate standard utility runs. After utilities are secured, you’ll install cement board or other backing materials to support the finishing surface. Finishes may include tile, stucco, brick veneer, or even metal siding.
Lastly, countertops and appliances are mounted. Most frame systems are designed to support heavy materials like granite or poured concrete, making them highly adaptable to luxury finishes.
Understanding the Costs of Sullivan Outdoor Kitchen Frames
When planning your project, it’s important to account for both the frame and the full kitchen build. Sullivan’s galvanized and stainless steel frames vary in price based on size, layout, and whether stainless steel is used throughout or selectively.
A smaller 6-foot straight-line frame setup may cost between $1,200 and $2,000. Mid-sized L-shaped frames can run between $1,800 and $2,800, while larger U-shaped configurations may start around $2,500 and go beyond $4,000.
When including finishes, appliances, and utilities, a fully outfitted outdoor kitchen using a Sullivan frame can range from $5,000 to over $20,000 depending on materials and complexity.
Keep in mind that stainless steel-only frames increase the cost, but they may pay off in longevity—especially in humid or coastal environments.
Design Before You Build: Outdoor Kitchen Visualizer Tools
One of the smartest steps before making a purchase is using an outdoor kitchen visualizer. These tools let you plan your layout, experiment with different finishes, and preview how your final setup will look—all within a digital environment.
You can choose your layout (straight, L-shape, U-shape), drag and drop grills, refrigerators, and sinks, and even receive real-time pricing estimates. Some platforms allow you to generate PDF plans or even use augmented reality to see your kitchen placed in your own backyard.
Using a visualizer can also help you determine which Sullivan frame kit matches your needs best, preventing over- or under-building.
Outdoor Kitchen Companies: Who’s Competing With Sullivan?
While Sullivan frames are popular for their balance of strength, versatility, and finish compatibility, they are part of a growing market.
Grillnetics offers aluminum-based modular kits that are lightweight and customizable. NewAge provides stainless steel cabinetry and appliance packages, great for homeowners who want a plug-and-play solution. WWOO, a European company, offers a minimalist concrete-based outdoor kitchen system.
However, many homeowners still prefer the Sullivan system for its builder-friendly blueprints, modular customization, and compatibility with high-end finishes.
Planning for Success: Using Outdoor Kitchen Blueprints
Whether you’re installing a prefab kit or going fully custom, blueprints are essential for getting the details right. Sullivan frames typically come with downloadable plans or CAD files tailored to your kitchen layout.
These blueprints show where to place appliances, how to run utilities, and where to reinforce the structure for heavier elements like pizza ovens or stone countertops. They also ensure proper ventilation and spacing—critical for both safety and functionality.
If you’re hiring a contractor, these documents become even more important. They’ll ensure the build meets code requirements and prevents costly mistakes during installation.
Prefab Outdoor Kitchen Kits: Pros and Cons
Prefab kits using Sullivan frames offer the convenience of structured assembly without sacrificing style. They arrive with pre-cut frame components, labeled for easy identification, and often include mounting options for appliances and countertops.
One major benefit of prefab options is the reduction in construction time. What might take weeks in a fully custom build can often be completed in a matter of days.
However, there are trade-offs. Prefab kits can limit your customization options—especially in terms of layout or niche appliances. They may also have higher upfront costs due to shipping or brand premiums. Yet, for many homeowners, the convenience and aesthetic uniformity outweigh those concerns.
Thinking DIY: Build Your Own Outdoor Kitchen
For the hands-on homeowner, building an outdoor kitchen from scratch using galvanized steel or stainless steel is a rewarding and cost-saving option.
By sourcing metal studs or steel tubing from local suppliers and using cement board as backing, you can create a custom frame suited perfectly to your space. This option allows for creative control and budget flexibility.
You’ll need a solid understanding of framing, some basic tools (metal snips, drill, level), and a plan for integrating utilities. Finish materials—such as tile or composite—can be chosen based on your climate and maintenance preferences.
The DIY approach isn’t for everyone, but it can save thousands while giving you a sense of ownership and pride in your build.
