Calculating the Costs: How Much Does it Cost to Build a BBQ Island?


Ready to take your backyard BBQ island ideas to take it to the next level? If grilling outdoors is your passion, you want more than just a freestanding outdoor grill. You love the convenience and functionality that a complete outdoor kitchen offers.

We’re talking about… an outdoor kitchen with island grills, an outdoor kitchen island with sink, an outdoor kitchen island with refrigerator, or a combination of an outdoor kitchen island with sink and refrigerator.

One of the first questions you ask before starting an outdoor kitchen project is, “how much does it cost to build outdoor kitchen grill islands?” The cost of outdoor kitchen projects varies, depending on the location, utilities, appliances, and other factors. It’s important to understand these factors to help you gauge your budget.

We'll go over the specifics in this article, starting with the cost factors…

Outdoor Kitchen Costs

Outdoor Kitchen Cost | Flame Authority - Trusted Dealer

1. Location for Outdoor Kitchens

When calculating the DIY cost for your outdoor kitchen project, one crucial factor to consider is the location, particularly the state you reside in. The costs associated with labor and materials can vary significantly from one state to another.

Obtaining a building permit is an important aspect to consider, and it can incur additional expenses. Depending on your location, the cost of a permit for a basic outdoor kitchen can be as low as $150, while for a more elaborate and intricate outdoor kitchen installation, it may reach up to $2,000.

Building Permit: $150 - $2,000

Moreover, the distance between your outdoor kitchen and your home is another factor that influences the overall cost. The farther the outdoor kitchen is from your residence, the higher the expenses involved.

It is essential to adhere to local building codes and regulations when constructing a permanent structure like an outdoor kitchen. These codes ensure the safety and compliance of the project, and failure to follow them may result in additional expenses or legal complications.

Considering the outdoor kitchen costs, project requirements, local codes, and location-specific factors will enable you to plan and budget effectively for your dream outdoor kitchen while adhering to all necessary regulations.

2. Outdoor Space for Outdoor Kitchens

How much space will you use for your outdoor island grill?

Existing living space: FREE

You won't have to worry about this expense if you already have an outdoor kitchen or an existing patio for your grill island. Unless you want to extend your patio or outdoor kitchen to add all your appliances and extra amenities.

New living space: $1,500 - $5,000

If you don’t have an existing patio yet and are planning to build one for your grill island, this is usually the cost of building a patio large enough to accommodate an average outdoor kitchen with grill island.

3. Utilities for Your Outdoor Kitchen

Utilities | Flame Authority - Trusted Dealer

You don't have to worry about the installation costs if your patio or outdoor kitchen already has gas and water lines. Otherwise, you need to install gas lines, water lines, and electrical lines, which will likely have the following estimated costs:

  • New Gas Lines: $15 - $25 per linear foot
  • Propane Gas: $3 - $5 per gallon
  • Electric: $50 - $100 per hour
  • Water sink and plumbing: $500 - $2000

It is crucial to ensure that utility lines and outlets for BBQ grills are properly set up to ensure smooth operation of your outdoor kitchen. Additionally, if you desire a BBQ island with a sink, new pipes and running water will need to be installed.

To incorporate an outdoor sink in your outdoor kitchen, you will need plumbing services, which can amount to approximately $500 to $2000, depending on the complexity of the installation.

Considering the outdoor kitchen cost, the need for gas lines, water lines, and electrical lines, and their associated costs per linear foot, it is essential to account for these expenses when planning your outdoor kitchen project.

The average outdoor kitchen costs will vary based on the specific requirements and the square footage of countertops, but incorporating these necessary installations is vital for a fully functional and enjoyable outdoor cooking space.
