What is a Grill Island?

Grill Islands or outdoor grilling islands provide a convenient food prep station. Although they are usually found next to full-sized outdoor kitchens, grill islands can be used on their own.

Outdoor kitchen grill islands are a great way to add space, extra cooking surface, storage, and seating to outdoor spaces in your home such as the backyard, patio, or deck.

You can also add extras like an outdoor refrigerator, island outdoor grill with sink, and an outdoor bar island with stylish seating. It's also an easy way to set up an outdoor island table, invite friends over, or just make dinner even more of an event.

You're probably asking yourself, "How to build an outdoor grill island?” – Well, if you got the skills, the tools, and a few helping hands, you can make an island grill. Below is the step-by-step guide that will make even the most overwhelming projects simple.

Step 1: DIY BBQ Island Planning Process

Before showing you how to build a BBQ island, let's start with a plan. Planning out your dream outdoor kitchen can seem like a daunting task. Let’s keep everything simple.

If you want a beautiful and practical outdoor kitchen, this guide is for you. 

Space and Location of BBQ Islands

Space and Location - Flame Authority

Your outdoor living space will be the first thing you need to worry about. After all, the size of your outdoor space will determine the size of the island grill.

Do you have a vacant lot that would be perfect for a beautiful outdoor kitchen? Do you already have a patio or backyard? Or do you need to set up one? 

One solution is to build your backyard island kitchen in an existing location. This includes using a space that is already available rather than letting it go unused or not having a better location to place it.

Do you prefer your outdoor grill kitchen near or far from your house? There are 2 types of outdoor island kitchens: Perimeter and Satellite.

  • Perimeter Outdoor Kitchen - located near or against your home's wall.
  • Satellite Outdoor Kitchen - located far from the house.

You should take a lot of things into account when you plan outdoor kitchen islands. Especially if you want an outdoor kitchen and grill island to be easy to access, space and location are very important. Next are utility lines...

Utility Lines

Outdoor Kitchen Utility Lines - Flame Authority

Depending on your choice of outdoor kitchen appliances, outdoor grill designs, and BBQ island designs and layout, make sure lines such as water, electricity, and gas lines are easily accessible. Usually, the outdoor kitchen gets its power, water, and gas lines from the house.

Do you plan to build an outdoor kitchen with sink? Check if a water line is installed in that area. If you prefer a natural gas outdoor kitchen or want natural gas grill islands, be sure to check if you have access to natural gas lines.

You will want BBQ grills outlets if your outdoor BBQ grills are electric. For your kitchen lights and other electrically powered appliances, you will also require electrical outlets.

Grill and Outdoor Appliances

Even though they are not necessary, they make outdoor cooking more fun!

Step 2: Materials Used for an Outdoor Kitchen

Materials Used for an Outdoor Kitchen - Flame Authority

When choosing materials, it's important to keep in mind that an indoor kitchen is different from an outdoor kitchen – more exposed to extreme weather conditions. The materials are the foundation of outdoor barbecue islands.

Stainless steel or metal outdoor kitchen with islands are the most common since they are lightweight, versatile, and reasonably priced. The only downside is that over time, even though the majority of metal frames are corrosion resistant, moisture will eventually penetrate into the metal frame, particularly in places with frequent freeze/thaw cycles.

Ever thought of how to build a BBQ island with wood? Unfortunately, using wood is not something we recommend. Why? Because wood is extremely prone to damage.

Concrete is a material you might want to consider because it won't rust or corrode when exposed to moisture. You can finish it with stucco, veneer stone, or stacked stone.

After a brief overview of the materials, let's go over the different construction types...

Step 3: Different Construction Types for Outdoor Kitchens

The frame is the key to your success. The frame method will be used to build outdoor kitchens – if you get it designed correctly, you'll have no trouble attaining your BBQ island ideas and goals!

Wood Frame

Wood | Flame Authority - Trusted Dealer

We don't really recommend using wood to build an outdoor kitchen as it won’t last for years. Nevertheless, wood frame DIY outdoor kitchens are common because they're simple and affordable. However, they are susceptible to damage and not weather resistant. Also, you will need insulated jackets and grill liners for your cooking equipment if you're going for a wood frame.

Metal Frame

stainless steel metal | Flame Authority - Trusted Dealer

Construction with metal frames is basically the same as construction with wood frames. If you're building it from scratch, you'll be in charge of doing all the preparation work, locating all the supplies, and cutting the metal studs. You'll need a few special considerations and tools to complete the job. Overall, metal and wood frames are both often constructed similarly.


concrete | Flame Authority - Trusted Dealer

Concrete construction definitely needs the most skill. Only use this method if you are experienced. The art of masonry is a totally different thing. Without prior masonry experience, building a concrete outdoor kitchen is going to be challenging. Aside from that, metal and wood are lighter than concrete blocks. Your patio or deck's structural footings may therefore need to be taken into consideration.

Step 4. Budget for DIY Outdoor Kitchen

Finally, the cost to build outdoor kitchen...

The resources you choose and the size of the outdoor BBQ islands will affect the total cost of your DIY Outdoor Kitchen project. If you're trying to keep costs down or stay within your budget, here's a tip: Make a list of your "needs" and "wants"

Just keep in mind that you should never compromise on the products and materials. Your outdoor kitchen won’t last a lifetime if you use low-quality materials.

When the price starts to seem a bit high, you can slash off some of your "wants". By doing this, you can keep all the important elements without going over budget.

And that's it!

Step 5. Pros and Cons of DIY Outdoor Kitchens
