Designing a circular pool is an exciting way to add a splash of luxury to your backyard.
Although professional installation is the safest option, many homeowners find that a round pool zum aufstellen winterfest can be built successfully using DIY.
Below is a user‑friendly guide that covers every stage—from preparation and excavation to finishing touches—allowing you to enjoy a beautiful, functional pool without overspending.

Know Your Site and Legal Requirements

1. Confirm Local Building Codes. Before you touch a shovel, check that your local municipality allows residential pools. You’re likely to need a permit, and there may be setbacks, fencing, and safety requirements you must comply with.
   
   
2. Check the Terrain. Level ground is best. If your yard slopes, you’ll need to level it or select a spot that naturally suits a round shape. Check for underground utilities—call your local utility services to mark lines.
   
   
3. Choose Size and Depth. Choose the diameter that fits your space and needs. Typical sizes range from 12 to 20 feet across. For depth, a shallow zone (3–4 ft) for lounging and a deeper area (5–7 ft) for swimming or diving supplies versatility.
   
   

Gather Materials and Tools

Excavator or backhoe (or a sturdy rented mini‑excavator for smaller pools)

Shovels, wheelbarrows, and a strong tarp for debris

A steel frame or wooden rim to outline the pool perimeter

Reinforcing steel bars (rebar) or a pre‑formed concrete circle

Waterproofing membrane (polyethylene liner or epoxy)

Pool plumbing kit (pump, filter, skimmer, return jets)

Pool tiles or coping stones for the lip

Concrete or plaster for the interior finish

Safety fence and gate (if required)

Keeping a detailed inventory list will help you avoid pricey last‑minute buys.

Step‑by‑Step Installation

1. Mark the Pool Outline. Use a garden hose or string to delineate the circle on the ground. Stake the ends securely. Use a tape measure to gauge the diameter. This guarantees a perfectly round pool.
   
   
2. Dig the Site. Remove soil to the required depth, ensuring a smooth, even slope from shallow to deep. The bottom should be level, especially in the shallow area. For concrete or plaster finishes, a level base is essential.
   
   
3. Build the Perimeter Frame. Erect a sturdy ring around the excavation’s edge. For a concrete pool, a steel rebar circle or a prefabricated ring is best. If opting for a vinyl liner, lay it over the excavated area and secure the edges with a rim or a sand ring.
   
   
4. Install the Waterproofing Layer.
   

Concrete Pools: Pour a concrete footing around the perimeter and embed rebar for reinforcement. Let the concrete cure for at least 28 days.

Vinyl Liner: Lay the liner over the bottom and sides, smoothing wrinkles carefully. Secure the edges with a rim or a ring of sand, making sure the liner is taut.

1. Lay Plumbing. Set up the skimmer, return jets, and filter system. Lay the plumbing lines through the rim of the pool. Embed plumbing before the concrete sets for concrete pools. For a vinyl liner, use a pre‑cut inlet to avoid cutting the liner.
   
   
2. Apply Interior Treatment.
   

Concrete: Once cured, apply a cementitious plaster or a specialized pool plaster. This yields a smooth surface for swimming.

* Vinyl: The liner is the interior surface; no further finish is required.

1. Install Coping or Tiles. Install coping stones, concrete coping, or decorative tiles around the lip. It looks polished and protects the rim from erosion.
   
   
2. Fill the Pool with Water. With everything in place and plumbing tested, fill the pool. Verify for leaks. If any appear, patch them promptly.
   
   
3. Start the Filtration System. Turn on the filter and pump for 24 hours to circulate water. Add chlorine or another sanitizer to maintain water purity.
   
   
4. Final Safety Check. Ensure all safety requirements are met—fencing, gate, and any required signage. If local code mandates a professional inspection, schedule it before using the pool.
   
   

DIY Pool Success Tips

• Plan for Drainage. Make sure the surrounding area is properly graded so water doesn’t pool around the foundation. A gentle slope away from the pool keeps the area dry.
  
  
• Frequent Level Use. A level catches uneven spots early, saving time and money. Check the bottom, walls, and coping for squareness.
  
  
• Ensure Liner Flatness. When working with vinyl, avoid cutting the liner. Instead, use gentle, even pressure to lay it out and use a roller to flatten it.
  
  
• Safeguard Your Tools. Store equipment in a dry place and maintain them regularly. A well‑kept shovel and wheelbarrow will last years.
  
  
• Budget Extras. Unexpected costs—such as extra sand, a small concrete patch, or a replacement liner—can sneak up. Set aside a contingency of 10–15% of your estimated budget.
  
  

Maintenance After Installation

• Test the pH and chlorine levels at least twice a week during heavy use.
  
  
• Keep the filter clean; run the pump for 8–12 hours each day.
  
  
• Inspect the coping stones and liner for cracks or wear.
  
  
• Perform a full water change every 3–4 months, or when the water looks cloudy.
