Make more space in your tiny camper kitchen with an RV countertop extension. These RV countertop extension ideas will give you more counter space when you need it and store away to take up zero storage space when you don’t.

What Is an RV Countertop Extension?

A countertop extension can be anything that creates more useable workspace in your RV kitchen while simultaneously being able to store away when not in use. These convenient surfaces make meal prep easier and can fit seamlessly into most RV kitchens.

Three primary types of countertop extensions can come with or be added to your RV:

  1. Sink or Stovetop Countertop Extensions
  2. Flip Up/Down Countertop Extensions
  3. Permanent Extension/Extended Overhang

You may also see hidden countertops behind cabinet doors for storing away those countertop appliances, though they are less common. We love this one turned into a little coffee nook:

Or, even less common, there are slide-out countertop extensions. These are rare to see in RVs, but are a possible DIY project.

Let’s dive into more detail on the three most common RV countertop extension options, including where to buy them and how to make your own.

Sink and Stovetop Covers

One of the simplest ways to extend your countertop is a stovetop cover or sink cover. Many RVs are built with sink covers or have stoves with built-in, foldable covers.

My Winnebago had covers made out of the same heavy-duty material as the countertop. If it weren’t for the faucet, you couldn’t tell there was a sink underneath! I used it sometimes for meal prep, but more often to hide dirty dishes when we had company over! 🫣

The stove also had a built-in glass cover. These are a little more common in new, manufactured RVs than sink covers.

If your RV didn’t come with one, you can buy a cover for your RV stove in a camping store or on Amazon. Or you find a small piece of countertop or butcher block and cut it to fit your space.

Amazon sells many different types of stove covers to fit 3- and 4-burner stoves.

Sink covers can be harder to find since sinks come in more varied sizes. (And many people opt to replace their RV sink anyway!) Camco, a popular brand for RV-related products, sells them in different sizes and styles.

DIY Sink or Stove Cover

For a newbie DIYer, creating a sink or stove cover is an easy project. Wood, purchased at your local lumber or home improvement store, is the most common choice for a DIY sink cover.

Here’s how to easily make your own:

Step 1: Measure your sink or stove (or both!) and figure out what size of wood you need. You may also consider buying a cutting board of the same size, but wood will be cheaper!

Step 2: Buy and cut your wood to size.

Step 3: Sand and round your corners. Keep your corners rounded to protect yourself from sharp edges. Use a jig saw to cut off the corners and then sand until smooth. If you want to create holes to easily pick up your board, grab a power drill with a large bit. Check out the video below to see more of this process.

Step 4: Apply cutting board oil to protect the wood. If you want a different wood color for your boards, you can stain it before applying the oil.

Ta-da! That’s all you need to do for a DIY sink or stove cover. The whole project should cost you less than $30 and give you a couple of extra feet of usable counter space.

Now, let’s look at flip-up countertop extensions.

Flip Up/Down Countertop Extensions

Sink and stove covers are great for creating a clean look in the kitchen, but more often, RVers stick the covers under the sink and forget about them. Flip-up countertops are the most popular countertop extensions we see used.

The above Grand Design was built with a flip-up countertop extension included. Flip-up countertop extensions fold away and are set up easily. Since sinks and stoves are used multiple times a day, their covers can be a minor annoyance as they get in the way.

While they are a little more expensive to build than sink covers, these flip-up countertop extensions are much more useful and the best option for more countertop space.

The only question is: to build or to buy?

Where to Buy a Countertop Extension

Amazon is one the easiest places to find RV countertop extension options. Camco offers different sizes and styles.

These countertop extensions will include the countertop itself as well as the mounting brackets you need to support it. They are available in a few different colors and styles.

But the best way to create an extra bit of counter space that perfectly matches your RV is to make your own.

Countertop Piece Options

For the countertop piece, the most popular look is wood, bamboo, or butcher block. You could order extra material when replacing your countertops, like this remodel:

Or buy a single square foot of wood or butcher block for cheap:

Permanent Countertop Extension

An easy way to add more counter space is to extend your counter over the edge of your cabinets. An “extended overhang” is a common way to create counter seating at a kitchen island.

This allows for permanent seating, but it also makes for a narrower walkway! Depending on the weight of your countertops and how far it extends, you may need to add supports under it, like in this renovation:

Extended overhangs are a great permanent solution for more counter space. Or, to really add more space, you could even add your own kitchen island!
