DIY SWIMMING POOL COSTS EXPLAINED
Building a DIY pool can offer numerous benefits, making it an appealing option for many homeowners. Firstly, it allows for significant cost savings compared to hiring professionals, as can manage labour and materials according to your budget. Additionally, building a pool as a DIY project gives you complete control over the design, size, and features, enabling you to create a personalised oasis suits your family's needs. Finally, the satisfaction of completing project like this can be immensely rewarding, as you enjoy the fruits of your labour for years to come.
To build a DIY swimming pool, you can choose from simpler options like a stock tank or a flat pack metal pool, or more involved projects such as an in-ground block and liner pool. Regardless of the option, you must prioritise safety, proper planning, and an effective filtration system.
For any permanent, in-ground installation, hiring a professional for key steps like electrical work is highly recommended.
Option 1: DIY stock tank pool
For a simple, affordable option, use a galvanised steel stock tank. Gather materials. You will need a stock tank of a suitable size, a pump and filter system, a pool hose kit, a drill, and a sealant.
Choose the location.
Pick a level area near a water source and an electrical outlet for the filter. Ensure the ground is firm enough to support the filled tank.
Install the filtration.
Following the pump manufacturer's instructions, drill holes for the filter intake and output fittings. Attach and seal the fittings to ensure they are watertight.
Connect and test.
Attach the pump and filter hoses. Before filling completely, add a few inches of water to check for leaks around the fittings.
Fill and maintain.
Fill the tank with water and begin running the filter. Use basic pool chemicals to balance the water and keep it clean.
Option 2: DIY flat pack timber pool
This above-ground method uses wooden panels to create the pool's structure.
Prepare the base.
Create a perfectly level area for the pool. Arrange the pallets into your desired shape and screw them together to form a sturdy frame.
Add support.
Use wood planks to reinforce the pallets and provide a smoother inner surface.
Line the pool.
Add a protective layer, such as tarps or old carpeting, inside the frame to shield the liner from screws and splinters. Then, install a waterproof pool liner, securing it neatly over the top edges.
Install the filter.
Cut holes and attach a pump and filter system, as described for the stock tank pool. Add the finishing touches. Build a small, simple deck or use pea gravel around the perimeter to finish the look.
Option 3: DIY block and liner in-ground pool
This is a more permanent and complex option that requires significant time, effort, and potentially professional help for excavation and electrical work.
Plan and prepare
Secure permissions and / or party wall agreements.
Check local regulations to see if you need planning permission for an in-ground pool, which is often not required for standard domestic installations.
Design and mark.
Create a detailed plan outlining the pool's dimensions and the location of the skimmer, returns, and pump. Mark the area for excavation.
Excavate the hole.
Dig the pool's shape and depth using a mechanical excavator. Ensure the ground is level for the foundation.
Lay the foundation.
Pour a concrete slab with a steel mesh for reinforcement to form the pool's floor.
Build the structure
Construct the walls.
Build up the pool walls with concrete blocks, typically nine courses high. Install a concrete ring beam behind the top of the walls for stability.
Add plumbing and electrical.
Install all plumbing for the filter system and any electrical connections for lighting. This electrical work should be done by a qualified electrician to ensure safety.
Render the walls.
Apply a layer of cement render to the walls and screed the floor. This provides a smooth, uniform surface for the liner and prevents punctures.
Finalise the pool
Install the liner.
Fit the liner lock around the perimeter of the pool. Stretch the heavy-duty vinyl liner over the pool, using a vacuum to remove all air and ensure a smooth, wrinkle-free finish.
Finish the surround.
Lay coping stones around the edge of the pool. Finish the area with paving stones or decking.
Set up the filter.
Connect and install the pump and filter in a nearby plant room, filling the filter with sand or glass media.
Fill and start up.
Fill the pool with water and add the necessary chemicals to balance the water before its first use.
One thing to note is that when you calculate the pricing for construction projects, you have to consider building materials, plant hire, and labour costs. Now while it is difficult to give a firm price without looking at actual site conditions, and also since the work would be done by yourselves, the guide prices for materials and plant hire costs for good quality concrete pool shells are very rough but are mentioned below.
