What’s Inside an RTA Panel? (Why Materials Matter Most)

When shopping for an outdoor kitchen, most people focus on how it looks—but what’s inside the structure is what determines how long it lasts.
So what’s actually inside an RTA panel?
In this episode of The Outdoor Kitchen Experience, we break down exactly what RTA outdoor kitchen panels are made of and why that construction matters for durability, weather resistance, and long-term performance. If you’re comparing RTA concrete kitchens to steel-frame or cement-board systems, this video will help you understand the differences that aren’t always obvious at first glance.
RTA panels are made from a high-strength concrete composite formed as one solid piece. There’s no steel framing to rust, no wood to rot, and no cement board to absorb moisture or fail over time. Instead of layered materials that depend on fasteners and adhesives, RTA panels use a monolithic concrete design that creates strength through simplicity.
We’ll also show how finishes are molded directly into the concrete—so nothing peels, delaminates, or separates—and how appliance cutouts are precision-cast at the factory for clean, accurate installs. Despite their strength, these panels are designed to be manageable, allowing two people to assemble a kitchen with basic tools and no on-site cutting.
If you want an outdoor kitchen that feels permanent, stable, and built for real outdoor conditions—sun, rain, heat, and freeze-thaw cycles—understanding what’s inside the panels is critical.

When you look at an outdoor kitchen,

0:01
most people just focus on the finish,

0:03
but what’s underneath it is what

0:05
determines how long it’ll actually last.

0:08
And that’s what people often ask us.

0:10
What exactly is in the inside of an RTA

0:12
panel? Hi, I’m Phil with RTA Outdoor

0:14
Living. [music] And today we’re going to

0:16
talk about what are our panels actually

0:18
made of? Because if you’re comparing

0:20
other outdoor kitchen options, the

0:22
materials inside the structure are one

0:24
of the most important things to

0:26
consider. Our panels are made with high

0:28
strength composite concrete. They’re not

0:30
hollow. They’re not framed with steel.

0:32
[music] It’s one solid piece of

0:34
structural concrete that’s engineered to

0:37
live outdoors for decades. The single

0:39
piece design creates a level of

0:41
durability you just don’t get from the

0:43
steel frame systems or even the cement

0:45
board systems that are going to rely on

0:48
layers. One of the biggest

0:49
differentiators when it comes to an RTA

0:51
panel is what’s not inside. There are no

0:54
steel studs to rust,

0:57
no wood to rot, no cement board to

1:00
absorb moisture or crumble over time.

1:03
The problem with these layered systems

1:05
is that one weak material eventually is

1:07
going to impact the entire structure.

1:10
With RTA, the integrity comes from one

1:12
single monolithic concrete form. The

1:15
texture you see on the outside of an RTA

1:18
panel isn’t stuck on. It’s molded

1:20
directly into the concrete. That means

1:23
no veneers, no adhesives, and nothing to

1:26
delaminate or peel over time. The

1:28
structure in the finish itself is the

1:31
same piece. That’s what makes it

1:33
incredibly strong and weather resistant.

1:36
Every RTA panel is cast with the exact

1:39
openings

1:41
for your grill,

1:44
for your fridge,

1:46
any other appliances that you have in

1:48
your [music] design. Because the

1:49
concrete is molded at the factory, the

1:52
cuts are going to be clean, accurate,

1:53
[music]

1:54
and ready to go for your installation.

1:56
There’s going to be no need for

1:57
additional cutting on site. No special

2:00
tools required, and no need to worry

2:02
about damaging the structure. Outdoor

2:04
kitchens live in tough environments.

2:06
Snow, rain, sun, you name it. Great

2:10
thing is concrete handles these

2:12
conditions [music]

2:13
better than almost any material. The

2:16
weight gives it its stability. The

2:18
density helps resist the weather. And

2:20
the simplicity, just having one

2:22
material, means fewer failure points

2:24
over the years. Even though these panels

2:26
are strong and substantial, they’re

2:28
designed to be manageable. Two to three

2:30
people can carry and install these

2:32
kitchens. These panels are designed to

2:34
interlock, bolt together, and create

2:37
[music] a solid structure without any of

2:39
the complex framing or messy

2:41
construction techniques like you might

2:43
find on some other systems. If you want

2:44
to take a closer look at how our panel

2:46
system works, try our free online design

2:49
tool or speak with one of our design

2:51
experts. We can walk you through the

2:54
materials, the layout, and help you see

2:57
exactly how an RTA kitchen will fit in

2:59
your space. I hope this video gave a

3:01
pretty clear picture of what’s actually

3:03
inside an RTA panel and why that matters

3:06
for our long-term durability. If you

3:09
have any questions about the materials

3:11
or installation, just ask. We’re here to

3:14
help.
