Building a small deck around an above ground pool is one of the most effective ways to improve both the safety and the aesthetic appeal of your backyard. Instead of just settling for a metal frame and a slippery surface, a deck creates a stable, comfortable platform where you can easily enter the water and relax poolside. This guide walks you through the entire process, from initial planning and material selection to the final touches that transform your pool area into a functional outdoor living space.
Planning Your Deck Layout and Size
Before purchasing any lumber, you need to determine the exact footprint of your deck. For a small deck, focus on the immediate area directly surrounding the pool's entry ladder; this provides a safe zone for getting in and out. You should also consider the diameter of your pool's access gate and any necessary clearance for maintenance equipment. Sketching a simple plan on graph paper helps visualize the structure and ensures you leave enough room for chairs or a small lounge area without crowding the pool itself.
Key Structural Considerations
- Ensure the deck surface is level with the top rail of the pool wall to make entry smooth.
- Keep the deck width to a minimum of 3 feet to allow for safe movement.
- Verify that the overhead clearance is adequate if the pool is beneath tree branches or power lines.
Choosing the Right Materials for Durability
The materials you select will dictate the longevity and maintenance requirements of your deck. While pressure-treated lumber is a cost-effective standard, tropical hardwoods like Ipe offer superior natural resistance to moisture and insects, albeit at a higher price point. For the decking surface, composite boards are an excellent choice because they resist splintering and fading, and they don't require the annual sealing that wood demands.
| Material | Pros | Cons |
|---|---|---|
| Pressure-Treated Pine | Affordable, widely available | Requires sealing, prone to warping |
| Composite Decking | Low maintenance, slip-resistant | Higher initial cost, can get hot in direct sun |
Foundation and Support Structure
An above ground pool exerts significant lateral pressure on the walls when filled with water, so your deck framing must account for this force. It is generally not recommended to attach the deck frame directly to the pool wall, as this can compromise the pool's structural integrity. Instead, build a freestanding frame anchored to concrete piers placed outside the pool wall. This method transfers the weight of the deck and the load of users safely into the ground, preventing deformation of the pool.
Step-by-Step Framing Process
- Mark the perimeter of the deck using stakes and string.
- Set concrete deck piers at the corners and at mid-points based on the span.
- Construct a rectangular frame using 2x6 or 2x8 joists secured with galvanized bolts.
- Ensure the frame is perfectly square using the 3-4-5 triangle method.
Installing the Decking and Safety Features
Once the frame is level and secure, you can begin laying the decking boards. Start from the edge of the pool and work your way outward, using stainless steel or coated screws to fasten the boards. Leave a small gap between planks to allow for water drainage and wood expansion. Safety is paramount in this environment; you should incorporate non-slip strips or apply a textured coating to the deck surface, especially in areas that will remain damp.
- Use bullnose trim on the edges where you sit to prevent sharp corners.
- Install low-voltage lighting beneath the deck frame for evening use.
- Consider adding a partial railing if the deck height exceeds 12 inches.
Finishing Touches and Long-Term Maintenance
To complete the look, you might want to add built-in features such as a bench or a small storage box underneath the deck structure to hold pool toys and chemicals. These additions should be constructed from the same materials to ensure visual cohesion. Long-term maintenance involves regular cleaning to remove algae and debris. If you used wood, a yearly application of sealant will protect the grain and prevent the deck from turning gray due to sun exposure.
Ultimately, a small deck around an above ground pool adds tremendous value to your outdoor experience. It transforms a simple swimming spot into a durable and inviting retreat where you can enjoy the water comfortably and safely for years to come.
