Grill Islands or Outdoor Grilling Islands provide a convenient prep station for outdoor cooking. 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 kitchen island with 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?” or “How to build an outdoor kitchen island grill?" – Well, if you got the skills, the tools, and a few helping hands, you can build an island grill or outdoor kitchen. Below is the step-by-step guide that will make even the most challenging projects simple.

1. The Planning Process

Before showing you how to build a BBQ island outdoor kitchen, 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

Space and Location - Flame Authority

Your outdoor living space will be the first thing you need. 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, 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 grill island with sink? Make sure a water line is installed in that area. If you prefer a natural gas outdoor kitchen or want natural gas grill islands, be sure 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

Aside from the grill BBQ, do you want to include any other appliances?

Homeowners are increasingly installing specialized equipment to their modern outdoor kitchen island, such as BBQ island drawers, island fridges, BBQ island with smokers, BBQ island doors, gas island grill heads, outdoor kitchen with freestanding grills, outdoor island vent hoods, and other portable outdoor kitchen island appliances.

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

Additionally, you should choose stainless steel appliances that can withstand the weather – from scorching hot summers to freezing cold winters. It’s wise to have a stainless steel outdoor kitchen island, which works well for all weather conditions.

Now that you've chosen your grill type, what size should it have?

It always comes down to how many people you'll be cooking for on a regular basis. If you only have a few guests, choose a smaller one. And of course, the more guests you have, the bigger the grill or a big island BBQ you'll need.

Size isn't just a grill thing, too... You should also take other appliances' sizes into account. Do you need a large fridge or could a smaller one be enough? Do you need more outdoor kitchen island cabinets? Perhaps you may eliminate some it turns out that you don't really need so many.

Determine your Appliance Budget

The final deciding factor: Your budget.

How much are you willing to spend on this DIY Outdoor Kitchen project and appliances? Additionally, there are plenty of grill options available. How much money you are ready to spend will determine what is feasible for your project.

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 outdoor kitchen islands 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.

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

3. Different Construction Types

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

Wood Frame

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

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 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.


Ready-to-Finish or RTF systems are designed to make processes easier. This type of system is a fast and efficient method to build DIY outdoor kitchens. RTF systems are partially completed and have already been trimmed and ready for installation. Some will also have pre-cut cement boards. Just install the appliances and utility lines and finish it out yourself.


Reading all these construction methods can be overwhelming as they need a lot of work and preparation, so we totally understand!

Luckily, you don't have to put yourself through all of this trouble!

Ready-to-Assemble or RTA Outdoor Kitchen Island Kits are the easiest DIY outdoor kitchen method, which can be completed in a few hours. It's as easy as putting together a piece of furniture! No expert skills are required.

4. Considerations for your budget

Finally, the cost to build outdoor kitchen...

The resources you choose and the size of the outdoor BBQ islands you build 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!
