Outdoor Kitchen Materials: What Actually Lasts Outside

Outdoor kitchen materials can look beautiful on day one—but will they still perform years from now?
Choosing the right outdoor kitchen materials is one of the most important decisions you’ll make when designing a space that’s built to last.
In this episode of The Outdoor Kitchen Experience, we break down what “outdoor-rated” really means and why an outdoor kitchen should never be treated like an indoor kitchen moved into the backyard.
Rain, humidity, direct sunlight, freezing temperatures, salt air, insects, and intense grill heat can all put outdoor kitchen construction materials to the test. Wood can swell, warp, rot, or attract insects. Certain metals can rust or corrode. Cement board and layered finishes can face challenges when exposed to moisture, freeze-thaw cycles, and changing outdoor conditions.
That’s why RTA Outdoor Living takes a different approach. Our primary outdoor kitchen system uses high-performance, microfiber-reinforced concrete structural panels designed specifically for outdoor environments. Concrete doesn’t rust or rot, and its non-combustible properties make it well suited for an outdoor cooking space.
But the structure is only part of the equation.
Outdoor-rated appliances also matter. We’ll explain why grills, refrigerators, burners, doors, and storage need to be selected with exterior exposure in mind—and why RTA commonly pairs its kitchens with Coyote outdoor appliances constructed with 304 stainless steel.
You’ll also learn why choosing a grill involves more than looks. Fuel type, appliance dimensions, ventilation, clearances, service access, cooking habits, and the overall kitchen layout all need to work together.

Have you ever seen an outdoor kitchen that looked great when it was brand new but started failing after a few seasons? Have you wondered why some materials rust, swell, crack, or just don’t hold up outside? You’re in the right place because outdoor rated is not just a nice

0:15
to have, it’s the foundation of a kitchen that actually lasts. In this video, I’ll explain what fails outside, why it fails, and how RTA thinks about both the kitchen structure and the appliances from day one. Hi, I’m Jordan from RTA Outdoor Living and today we’re

0:30
talking about why outdoor rated materials and appliances matter so much when you’re building an outdoor kitchen. The easiest way to think about this is simple. An outdoor kitchen is not just an indoor kitchen placed outside. Indoor cabinets, indoor finishes, and indoor

0:45
appliances are not built for rain, humidity, direct sun, freezing temperatures, heat from grills, insects, or salt air. Outside, everything gets tested. If a material absorbs moisture,

1:00
it can swell, crack, rot, or break down. If metal is not protected or is the wrong grade, it can rust or corrode. If a finish is only stuck onto the surface, it can start to separate over time. One of the most common problem areas is the

1:15
structure of the kitchen itself. Some outdoor kitchens use metal frames, wood frames, cement board, masonry layers, or surface cladding. Some of those materials can work in the right situation, but each one has its weaknesses. Wood is combustible, can

1:30
rot, warp, swell, or attract insects. Metal can rust or corrode when moisture gets inside the structure. Cement board may be water resistant, but that does not mean it is immune to outdoor moisture, especially in freeze, thaw,

1:45
humid, or coastal environments. And with layered finishes like tile, stone veneer, stucco, the risk is that the outer layer can crack, flate, or delaminate if the system is not built correctly. That is

2:00
why RTA takes a different approach with our main outdoor kitchen system. RTA kitchen panels are made from high-performance concrete reinforced with microfers. The idea is to create a structural panel that is built for

2:15
outdoor conditions. instead of building a frame first and then depending on multiple layers to protect it. Concrete is non-combustible. It does not rust and it does not rot. That matters because the structure is

2:30
what supports the grill, appliances, countertops, and the entire outdoor kitchen experience. [music] But outdoor rated is not just about the island. The appliances matter just as much. A grill, refrigerator, side burner, access door, or storage drawer

2:45
is going to be exposed to moisture, grease, heat, temperature swings, and everyday use. If the appliance is made with lower quality materials, it may look fine at first, but over time it can tarnish, rust, corrode, or become harder

3:00
to use. That’s why RTA commonly works with Coyote outdoor appliances, which are built from 304 stainless steel and [music] designed specifically for outdoor use. The other thing homeowners should know is that the appliance fit matters. You just don’t pick a grill because it looks good and then hope it

3:15
works in the island. You need to think about size, fuel type, ventilation, clearances, access for service, and how the appliance actually supports the way you cook. A customer who grills once a month may need a different setup than

3:30
somebody who wants a grill, side burner, refrigerator, storage, and a full entertaining station. So, the big takeaway of this is outdoor rated is not optional if you want an outdoor kitchen to last. It affects the structure, the finish, the appliances, the safety of

3:45
the installation, and the long-term experience of using the space. RTA is a good fit for homeowners who want an outdoor kitchen designed as a complete outdoor system, not a collection of indoor ideas forced into an outdoor

environment. Try our free outdoor kitchen design tool. And if you’re unsure which materials or appliances are right for your backyard, book a free consultation with one of our design experts.
