How to Build an Above Ground Pool Deck: Easy Steps

Adding a deck to your above ground pool not only enhances the overall look of your backyard but also provides a functional space for lounging, sunbathing, and hosting poolside gatherings. With the right tools, materials, and a clear plan, building a deck for your above ground pool can be a rewarding DIY project. In this comprehensive guide, we’ll walk you through the step-by-step process of building an above ground pool deck, from planning and preparation to construction and finishing touches.

Step 1: Planning and Preparation

Before you start building your above ground pool deck, it’s essential to carefully plan and prepare for the project. Here are the key steps to consider:

1.1 Determine The Size And Layout

Start by deciding on the size and layout of your deck. Consider the shape and dimensions of your pool, as well as the available space in your backyard. The deck should complement the pool while leaving enough room for movement and furniture.

1.2 Obtain Necessary Permits

Check with your local building department to determine if you need any permits for constructing a deck. Compliance with local building codes is crucial to ensure the safety and structural integrity of your deck.

1.3 Gather Tools And Materials

Make a list of all the tools and materials you’ll need for the project. This may include lumber, concrete, nails, screws, joist hangers, post anchors, and more. Having everything ready before you begin will streamline the construction process.

Step 2: Building the Foundation

The foundation is the most critical part of your above ground pool deck. It provides the support and stability necessary for the structure. Here’s how to build a solid foundation:

2.1 Mark The Deck Layout

Using stakes and string, mark the perimeter of the deck according to your planned layout. This will give you a clear visual guide as you begin the construction process.

2.2 Prepare The Ground

Clear the area where the deck will be built, removing any grass, rocks, or debris. Level the ground and compact the soil to create a firm and even base for the foundation.

2.3 Install Concrete Piers

For a stable foundation, install concrete piers at key points along the deck’s perimeter. These piers will support the weight of the deck and prevent it from sinking into the ground over time.

2.4 Set Support Posts And Beams

Once the concrete piers have set, place support posts on top of them and secure horizontal beams to create the framework for the deck. Use a level to ensure that the posts and beams are perfectly aligned.

Step 3: Constructing the Deck Frame

With the foundation in place, it’s time to build the frame of your above ground pool deck. This involves installing the joists, ledger board, and other structural elements.

3.1 Attach The Ledger Board

Secure a ledger board to the side of your pool, ensuring that it is level and firmly anchored. This board will provide support for the joists and the outer edge of the deck.

3.2 Install The Joists

Place the joists perpendicular to the ledger board, spacing them according to your design plans. Use joist hangers to attach the joists securely to the support beams, ensuring a strong and stable frame.

3.3 Add Decking Boards

Once the frame is in place, you can start laying the decking boards across the joists. Choose high-quality, weather-resistant boards that can withstand exposure to water and sunlight.

Step 4: Adding Railings and Stairs

For safety and aesthetics, consider adding railings and stairs to your above ground pool deck. These features provide additional security and accessibility for users.

4.1 Install Railings

Attach sturdy railings along the perimeter of the deck, ensuring that they meet local building codes for height and spacing. Railings not only enhance safety but also add a decorative touch to the deck.

4.2 Build Stairs Or Ladder

If your deck is elevated, you’ll need to construct stairs or a ladder for easy access to the pool. Ensure that the stairs or ladder are securely attached and provide a safe transition from the deck to the pool area.

Step 5: Finishing Touches

Once the main structure of your above ground pool deck is complete, it’s time to add the finishing touches that will enhance its appearance and functionality.

5.1 Apply A Protective Finish

To prolong the life of your deck and protect it from the elements, consider applying a waterproof sealant or a weather-resistant stain. This will help prevent warping, rotting, and fading of the wood.

5.2 Furnish And Decorate

Add outdoor furniture, umbrellas, and decorative elements to your deck to create a welcoming and comfortable poolside area. Consider incorporating storage benches or containers for pool toys and accessories.

5.3 Landscaping And Lighting

Enhance the visual appeal of your deck by adding landscaping around the perimeter. Planting shrubs, flowers, or installing lighting can create a relaxing and inviting atmosphere for your outdoor space.


Building an above ground pool deck is a rewarding project that can significantly enhance the enjoyment and functionality of your outdoor space. By following the steps outlined in this guide and taking the time to plan, prepare, and construct the deck carefully, you can create a beautiful and durable addition to your pool.
