Build a Garden Pool: Planning, Costs & DIY

How to plan your garden pool properly

A garden pool is not an impulse purchase. Planning determines its success and your long-term enjoyment. Start with a realistic assessment of your garden. Measure the available space carefully. Observe legal requirements such as boundary distances. Find out early whether you need planning permission.

Set your priorities. Do you want to swim for exercise or simply cool off? Should the pool remain visible all year round or be covered in winter? The answers determine its size, shape and features. Also think about how you will use it later: a wide staircase or integrated seating area can make the pool more comfortable.

Choosing the right pool type

You have a fundamental choice between an above-ground and an in-ground pool. Above-ground pools are quick to install and cost-effective. However, they often look less premium and are more susceptible to damage. In-ground pools blend into the garden landscape.

These are the common construction types for in-ground pools:

• Prefabricated plastic pools: Prefabricated shells made from GRP (glass-reinforced plastic). Advantages: quick installation, smooth surface and resistance to algae. Disadvantage: shapes and sizes are predetermined.
• Steel-wall pools: A steel wall is assembled in the excavated hole and lined with a pool liner. Flexible in terms of size, but requires a level concrete base.
• Concrete pools: The premium option. Cast from reinforced concrete and rendered or tiled. Maximum freedom in terms of shape, size and features. Requires professional planning and construction.

Choosing a pool type should always involve weighing up your budget, design preferences and the amount of work involved. A concrete pool is an investment for generations, while a prefabricated pool can be completed more quickly.

How do you build a DIY pool?

Building a pool yourself is a demanding project. Complete kits with instructions are available for prefabricated or steel-wall pools. Your work starts with the excavation. You dig out the pit, taking care to work precisely. The base must be absolutely level and well compacted.

Next, install the pool shell or steel wall. This is followed by installing the filter equipment, skimmers and inlet nozzles. Care is essential here, as leaks are difficult to repair later. Always call in a professional for all electrical connections and the pipework for the filtration system.

To fill the pool, you need a sturdy hose line. A long, high-quality garden hose or a special pressure hose is ideal. Allow several hours to days for filling.

Choosing the right pool equipment

The filter pump is the heart of the system. It keeps the water clean by forcing it through a sand filter or cartridge filter. Its capacity must match the pool size. A pump that is too weak will not clean the water effectively. A pump that is too powerful wastes energy unnecessarily.

Water care includes a disinfection system. The traditional option is a chlorination system. Alternatives include saltwater electrolysis, UV systems or ozone treatment. Each system has advantages and disadvantages in terms of cost, maintenance and effectiveness.

A pool heater significantly extends the swimming season. Heat pumps are efficient, while solar collectors on the roof or ground are sustainable. Electric instantaneous water heaters are only suitable for very small pools.

What does it cost to build your own pool?

The costs consist of many items. The pool price alone is only the beginning. Always include a buffer of at least 15 percent for unforeseen expenses. The biggest cost areas are excavation, the pool itself, the equipment and the surrounding landscaping.

For a solid prefabricated pool with filter system, installation and a simple concrete surround, you should expect to pay () 10.000 to 20.000 Euro. An individual concrete pool starts at 30.000 Euro. There is no upper limit if you want elaborate landscaping, a pool enclosure, lighting and heating.

Hidden and ongoing costs

Further costs arise alongside the obvious items. These include disposing of the excavated soil. Can you use the soil on your property? If not, removal can be expensive. There must also be access for an excavator; otherwise, the excavation has to be done by hand, which drives up costs.

The pool surround, often made from concrete, natural stone or wood, is a major expense. A patio directly beside the pool increases both comfort and costs. Also plan storage space for pool accessories such as nets, pool vacuums and chemicals. A small garden shed or an underground equipment pit are sensible investments.

Many property owners underestimate the work involved in perfecting the pool surroundings. A pool on its own can often look out of place. Only harmonious integration into the garden design, with suitable planting, lighting and seating, creates the desired oasis of comfort.

Top Tips for Pool Maintenance

A clean pool is the result of regular maintenance. The three key areas are filtration, water chemistry and mechanical cleaning. Run your filter pump for long enough every day. During peak season, eight to twelve hours is usual. A skimmer catches coarse dirt such as leaves.

Check the pH level and chlorine content at least twice a week. The pH level should be between 7.0 and 7.4. A level that is too high or too low makes chlorine ineffective and can damage materials. For dosing pool care products, () and () are practical helpers.

You should clean the pool floor with a pool vacuum every week. This is either connected to the filter pump or available as a standalone device with a filter bag. Brush the walls and waterline regularly to remove algae and limescale deposits.

Winterising Your Pool and Starting the Season

Proper winterisation protects your pool from frost damage. Lower the water level below the inlet nozzles. Empty all pipes, the filter pump and the sand filter. Add winter pool chemicals to the water to prevent algae growth. Cover the pool with a sturdy tarpaulin.

At the start of the season, remove the cover and clean it thoroughly. Fill the pool back up to its normal level. Backwash the sand filter and start the filtration system. Check all seals and connections. Before swimming, bring the water values into the optimum range using shock chlorination and pH regulators.

The right tools make maintenance easier. Alongside a pool net and pool vacuum, a good pool brush and a water test kit are essential. In our range of garden tools, you will find durable accessories.

The pool size, distance from the property boundary and depth are key factors. Always check with your local building authority before planning. Using well water may also require a permit.

Can I build a garden pool myself?

Yes, DIY construction is realistic for certain pool types. Steel-wall or prefabricated plastic pools are often supplied as kits. You then carry out the excavation work, level the base and assemble the pool. Concrete pools or complex technology require specialist knowledge. Always have a professional handle electrical and water connections.

How much does an average garden pool cost?
