Building a DIY round pool offers an accessible entry point into the world of backyard water features. Unlike their above-ground counterparts, these structures combine the visual appeal of a circular design with the installation relative simplicity of an above-ground pool. This guide walks you through the entire process, from initial planning to final water testing, ensuring you create a safe and enjoyable retreat.
Planning Your Round Pool Project
The success of your project begins long before the first shovel hits the ground. Careful planning saves time, money, and potential frustration down the line. You must consider the specific location, available space, and your budget constraints with equal weight.
Site Selection and Ground Preparation
Choosing the right spot is crucial for safety and longevity. Opt for a flat, level area that receives ample sunlight but is also shaded during the hottest parts of the day to reduce algae growth and water evaporation. Avoid placing the pool under trees to minimize leaf debris. Once you have a location, use a garden hose to outline the shape and ensure the space fits your chosen model. Clear the area of any sharp objects, rocks, or roots, and level the ground thoroughly. A solid, flat base is essential to prevent the walls from bowing or collapsing under pressure.
Selecting the Right Equipment
Not all round pools are created equal, and the equipment you choose dictates the pool's performance and maintenance needs. You will need a structure, a filtration system, and a means of heating if you plan to extend the swimming season.
| Equipment Type | Key Considerations | Purpose |
|---|---|---|
| Pool Wall Kit | Height (48" vs 52"), Material (steel or aluminum), Interlock System | Defines the perimeter and water retention |
| Pump and Filter | Flow Rate (GPH), Filter Type (Sand, Cartridge, DE) | Circulates water and removes debris |
| Heating System | Solar Mats, Heat Pump, or Gas Heater | Extends the usability into cooler months |
Step-by-Step Installation Process
With your site prepped and equipment selected, you can move on to the physical assembly. This process requires two people for handling the liner and wall sections safely. Follow the manufacturer's instructions closely, as designs can vary significantly between brands.
Assembling the Frame
Begin by assembling the base track or wall panels according to the diagram provided. Interlock the sections carefully, ensuring the circle remains perfectly round. Use a rubber mallet to gently tap joints into place. Once the wall is upright, install the top rail and secure it with the provided caps. This frame acts as the skeleton of your pool, so precision is vital.
Installing the Liner
The liner is the waterproof barrier that holds the water in place. Lay the liner flat inside the frame, ensuring the bottom settlement wrinkles are uniform to allow for even stretching. Attach the liner to the top rail using the coping tracks and clips. This is where the second person is indispensable; you will need to hold the liner taut while the other side clips it in place. Gradually fill the pool with water, allowing the weight of the water to smooth out the wrinkles as you go. Stop filling once the water reaches the bottom rung of the skimmer opening.
Finalizing and Water Chemistry
With the pool full, you can complete the installation of the filtration system and any additional accessories like ladders or handrails. Connect the pump and hoses, ensuring all clamps are tight to prevent leaks. Before diving in, you must address the chemical balance of the water to ensure it is safe for swimming.
Test the water using a kit or strips to measure pH, alkalinity, and chlorine levels. Aim for a pH between 7.2 and 7.6, with total alkalinity around 80-120 ppm. Add the necessary chemicals incrementally, allowing the filtration system to run for several hours before retesting. Maintaining this balance weekly prevents algae, protects the liner, and ensures a comfortable swimming experience for you and your family.
Maintenance and Longevity Tips
A DIY round pool is an investment, and proper maintenance protects that investment. Regular care is less about dramatic cleaning sessions and more about consistent, small habits. Skim the surface daily to remove leaves and insects, and brush the walls weekly to prevent algae from taking hold in the corners.
During the off-season, winterizing the pool correctly is just as important as setting it up. Lower the water level below the skimmer, drain all equipment, and clean the liner thoroughly before storing it in a cool, dry place. Covering the pool tightly protects it from UV damage and debris, extending the life of the structure and ensuring many seasons of enjoyment.
