Creating a round pool is a thrilling way to bring luxury to your backyard.
Even though professional installation is safest, many homeowners discover that a round pool can be built successfully via DIY.
Below is an easy‑to‑follow guide that walks you through every phase of the process—from preparation and excavation to finishing touches—so you can enjoy a beautiful, functional pool without breaking the bank.

Know Your Site and Legal Regulations

1. Check Local Construction Codes. Before you touch a shovel, verify that your local municipality allows residential pools. A permit will probably be required, along with setbacks, fencing, and safety requirements you must meet.
   
   
2. Assess the Terrain. Level ground is best. If your yard slopes, you’ll need to level it or pick a spot that naturally fits a round shape. Check for underground utilities—call your local utility services to mark lines.
   
   
3. Choose Size and Depth. Decide on the diameter that fits your space and needs. Common 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 will give you versatility.
   
   

Collect Materials and Tools

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

Shovels, wheelbarrows, and a robust tarp for debris

A steel frame or wooden rim to define the pool perimeter

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

Waterproofing membrane (polyethylene liner or epoxy coating)

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)

Having a clear inventory list can prevent costly last‑minute buys.

Step‑by‑Step Installation

1. Mark the Pool Outline. Use a garden hose or string to mark the circle on the ground. Fasten the ends securely. Measure the diameter with a tape measure. This ensures the pool will be perfectly round.
   
   
2. Dig the Site. Dig to the required depth, maintaining a smooth, even slope from shallow to deep. The bottom should be level, especially in the shallow area. If you’re using a concrete or plaster finish, a level base is essential.
   
   
3. Install the Perimeter Frame. Erect a sturdy ring around the excavation’s edge. For a concrete pool, a steel rebar circle or a prefabricated ring works best. If you choose a vinyl liner, simply lay the liner over the excavated area and secure the edges with a rim or a ring of sand.
   
   
4. Lay the Waterproofing Layer.
   

Concrete Pools: Pour a concrete footing around the perimeter, then embed rebar for reinforcement. Cure the concrete for at least 28 days.

Vinyl Liner: Position the liner over the bottom and sides, smoothing wrinkles carefully. Fasten the edges with a rim or a sand ring, ensuring the liner stays taut.

1. Install Plumbing. Install the skimmer, return jets, aufstellpool angebote and filter system. Thread the plumbing lines through the rim of the pool. Insert the plumbing before the concrete sets for concrete pools. Use a pre‑cut inlet for vinyl liners to avoid cutting the liner.
   
   
2. Apply the Interior Finish.
   

Concrete: After curing, apply a cementitious plaster or a special pool plaster. This provides a smooth surface for swimming.

* Vinyl: No additional finish is needed; the liner itself is the interior surface.

1. Apply Coping or Tiles. Lay coping stones, concrete coping, or decorative tiles around the lip. This not only looks polished but also protects the rim from erosion.
   
   
2. Fill with Water. Once everything is in place and plumbing is tested, fill the pool. Check for leaks. If any appear, patch them promptly.
   
   
3. Run the Filtration System. Run the filter and pump for 24 hours to circulate the water. Add chlorine or another sanitizer to keep water quality.
   
   
4. Final Safety Check. Confirm that all safety requirements are met—fencing, gate, and any required signage. If your local code requires a professional inspection, schedule it before you start using the pool.
   
   

Tips for a Successful DIY Pool

• Drainage Tips. Ensure the surrounding area has proper grading so water doesn’t pool around the foundation. A gentle slope away from the pool helps keep the area dry.
  
  
• Level Frequently. A level catches uneven spots early, saving time and money. Check the bottom, walls, and coping for squareness.
  
  
• Keep the Liner Flat. When working with vinyl, avoid cutting the liner. Lay it out with gentle, even pressure and a roller to flatten it instead.
  
  
• Protect Tools. Store all equipment in a dry place and maintain them regularly. A well‑kept shovel and wheelbarrow will last years.
  
  
• Budget for Extras. Unexpected costs—like extra sand, a small concrete patch, or a replacement liner—can sneak up. Allocate 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.
