Installation Process

Installing a prefab plunge pool is a straightforward and rewarding process. To make it even easier, let’s break it down into four simple steps: site preparation, pool placement, landscaping, and finishing touches.

1. Site Preparation

Preparing the site for your plunge pool installation is crucial. Start by acquiring the necessary permits and building approvals from your local town hall or government center. Then, ensure the area is cleared of debris, vegetation, or obstacles. It’s also good to check for underground utilities and confirm the site’s accessibility for heavy equipment like excavators and cranes.

2. Pool Placement

Next, decide on the perfect location for your plunge pool. Consider factors such as sun exposure, privacy, and proximity to your home. A professional will excavate the area to the required depth, ensuring the ground is level and stable. They will then set the prefab pool into the excavated space using a crane, ensuring it is in the correct position and properly aligned.

3. Landscaping

Now that your pool is in place, it’s time to consider landscaping. Customizing the area around your pool can enhance the overall ambiance and increase your enjoyment of the space. Opt for a pool deck in materials like tile or wood, and consider adding elements like plants, decorative stones, and outdoor lighting for added flair.

4. Finishing Touches

Finally, focus on the finishing touches that will make your plunge pool exceptional. Install essential equipment like pumps, filters, and heaters, and add your desired pool seating, steps, or rails. Complete the process with desired water features, spa jets, or lighting options to create a relaxing and inviting oasis for you and your guests.

Maintenance and Care

When owning a prefab plunge pool, it’s essential to understand the basic maintenance and care procedures to ensure your pool stays in top condition. This section will help guide you through the key aspects of maintaining your plunge pool, including water chemistry, cleaning, and filtration.

Water Chemistry

Proper water chemistry is vital to maintaining a healthy and safe environment in your plunge pool. The following factors should be regularly monitored:

  • pH levels: Maintain a balanced pH between 7.2 and 7.8 to ensure optimal sanitation and swimmer comfort.
  • Chlorine: Strict the pool’s chlorine levels to prevent bacteria and algae growth. The ideal range is between 1 and 3 parts per million (ppm).
  • Alkalinity: Aim for an alkalinity range of 80 to 120 ppm to minimize pH fluctuations and support efficient chlorine performance.
  • Calcium hardness: A 200 to 400 ppm level helps prevent corrosion and scaling in the pool’s equipment and surfaces.

Regularly test your pool’s water chemistry using test kits or digital testing devices and adjust the levels by adding the necessary chemicals.


Routine cleaning is critical in maintaining a clean and visually appealing plunge pool. Remember to:

  • Skim the surface: Use a pool net to remove leaves, debris, and insects that accumulate on the water’s surface.
  • Brush the pool walls and floor: Prevent algae and dirt buildup by brushing your pool’s surfaces with a pool brush.
  • Empty the skimmer baskets: Remove collected debris from skimmer baskets regularly to ensure optimal water circulation.

In addition, as plunge pools require less maintenance than full-size pools, you can typically use a handheld pool vacuum to keep them clean.


A well-functioning filtration system is essential for maintaining clear and healthy water in your plunge pool. Consider the following tips:

  • Run the filter: Operate your pool’s filtration system for at least 8-12 hours daily to filter out impurities and circulate the water.
  • Inspect the filter: Check your pool filter for clogs or damaged components. Clean, repair, or replace as needed.
  • Backwash the filter: Depending on the filter type, you may need to perform periodic backwashing to remove accumulated debris and prolong the filter’s lifespan.

By diligently following these maintenance and care guidelines, you’ll be able to enjoy a clean, safe, and inviting prefab plunge pool for years to come.
