Build a Backyard Pool: Planning, Costs & DIY

How to plan your backyard pool

A backyard pool is not an impulse purchase. Planning determines how successful it will be and how much you enjoy it over the long term. Start with a realistic assessment of your yard. Measure the available space carefully. Check local requirements, such as setbacks from property lines, and find out early whether you need a permit.

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

Choosing the right pool type

Your main choice is between an above-ground pool and an in-ground pool. Above-ground pools are quick to install and affordable. However, they often look less upscale and are more prone to damage. In-ground pools blend into the landscape.

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

• Prefabricated plastic pools: Factory-made shells made from GRP (glass-reinforced plastic). Advantages: quick installation, a smooth surface and resistance to algae. Disadvantage: the shapes and sizes are predetermined.
• Steel-wall pools: A steel wall is assembled in the excavated hole and lined with a pool liner. These pools offer flexibility in size but require a level concrete base.
• Concrete pools: The premium option. Built from reinforced concrete and finished with plaster or tile. They offer maximum freedom in shape, size and features, but require professional planning and construction.

When choosing a pool type, weigh 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 and steel-wall pools. The work starts with excavation. Dig out the pit, taking care to work precisely. The base must be perfectly level and well compacted.

Next, install the pool shell or steel wall, followed by the filter equipment, skimmers and return jets. Care is essential, as leaks can be difficult to repair later. Always hire a professional for electrical connections and the filtration system's plumbing.

To fill the pool, you need a sturdy hose line. A long, high-quality garden hose or a special pressure hose works well. 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 pushing 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. One that is too powerful wastes energy.

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

A pool heater can significantly extend the swimming season. Heat pumps are efficient, while solar collectors on the roof or ground offer a sustainable option. Electric tankless water heaters are suitable only for very small pools.

What does it cost to build your own pool?

Pool costs include many items, and the pool itself is only the beginning. Always budget at least 15 percent extra for unexpected expenses. The biggest cost areas are excavation, the pool, equipment and surrounding landscaping.

For a solid prefabricated pool with a filter system, installation and a simple concrete surround, expect to pay () 10.000 to 20.000 Euro. A custom 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

Other costs can add up alongside the obvious ones. These include disposing of excavated soil. Can you use the soil on your property? If not, hauling it away can be expensive. You also need access for an excavator; otherwise, the work must be done by hand, which drives up costs.

The pool surround, often made of concrete, natural stone or wood, can be a major expense. A patio right beside the pool adds comfort and cost. Also plan storage space for pool accessories such as nets, pool vacuums and chemicals. A small garden shed or an underground equipment pit can be a smart investment.

Many property owners underestimate the work involved in finishing the area around the pool. A pool by itself can look out of place. Harmonious integration into the landscape, with suitable planting, lighting and seating, creates the comfortable oasis they want.

Top Tips for Pool Maintenance

A clean pool takes regular maintenance. The three key areas are filtration, water chemistry and mechanical cleaning. Run your filter pump long enough each day. During peak season, eight to twelve hours is typical. A skimmer catches larger debris 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. If it is too high or too low, chlorine becomes less effective and materials can be damaged. For dosing pool care products, () and () are handy tools.

Clean the pool floor with a pool vacuum every week. It either connects to the filter pump or works as a standalone device with a filter bag. Brush the walls and waterline regularly to remove algae and limescale deposits.

Winterizing Your Pool and Starting the Season

Proper winterization protects your pool from freeze damage. Lower the water level below the return jets. 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 tarp.

At the start of the season, remove the cover and clean it thoroughly. Refill the pool to its normal level. Backwash the sand filter and start the filtration system. Check all seals and connections. Before swimming, bring the water chemistry into the optimal range with shock chlorination and pH adjusters.

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

Frequently Asked Questions

Do I need a permit to build a pool in my backyard?

Requirements vary by state and local authority. In-ground pools generally require a building permit. The pool’s size and depth, as well as its distance from the property line, are key factors. Check with your local building department before you start planning. You may also need a permit to use well water.

Can I build a backyard pool myself?

Yes, some types of pools are suitable for DIY installation. Steel-wall and prefabricated plastic pools often come as kits. You’ll handle the excavation, level the base and assemble the pool. Concrete pools and complex pool systems require specialist knowledge. Always hire a professional to handle electrical and water connections.

How much does a backyard pool typically cost?

Costs vary widely. A small above-ground pool costs less than 1,000 Euro. A sturdy, medium-sized prefabricated pool costs between 5,000 and (PRODUCT_40286) 15,000 Euro, including the filtration system. A custom concrete pool with landscaping, a cover and high-end equipment starts at 30,000 Euro and can quickly run into six figures.

Where should I put a pool in my backyard?

Choose a sunny, sheltered spot with ground that’s as level as possible. Keep the pool far enough from trees to avoid problems with falling leaves and roots. Make sure there’s room for excavators and delivery trucks to access the site. Consider the view from your patio and how much privacy you want. A well-planned garden space helps the pool blend in naturally.

How much maintenance does a backyard pool need?

Daily maintenance includes removing larger debris and checking the pH and chlorine levels. Clean the filtration system and vacuum the pool floor each week. You’ll also need to shock the pool several times during the season. A reliable water supply and a good garden hose make topping off the pool much easier. Before winter, be sure to winterize it properly.
