Installation Process: Custom vs Precast Plunge Pool

Have you wondered which plunge pool type—custom or precast—is best for your backyard? Opt for a custom plunge pool if you want a unique design that perfectly matches your preferences and complements your outdoor space.

Both options have their benefits, but your choice depends on your priorities.

What Are Custom and Precast Plunge Pools?

Custom Plunge Pools

Custom plunge pools are built on-site. They offer complete flexibility in shape, size, and design. Features like lighting, jets, or unique finishes can be added to match your preferences. These pools are ideal for homeowners wanting a pool that aligns with their property’s layout.

Precast Plunge Pools

Precast plunge pools are made in a factory and delivered to your property. They are available in standard sizes and shapes, offering quick and affordable installation. Precast pools are perfect for homeowners who want simplicity and cost-effectiveness without compromising style.

Benefits and Trade-Offs of Each Type

Custom Pools

  • Benefits: Custom pools offer complete design freedom. You can choose the shape, size, and features to match your preferences. They integrate well with landscaping and allow for specific additions like jets or lighting.
  • Trade-Offs: Custom pools are more expensive, require longer installation times, and need experienced builders for construction.

Precast Pools

  • Benefits: Precast pools are quicker to install, cost less, and have consistent quality due to factory production.
  • Trade-Offs: They have limited customisation options and often require crane access for installation.

Key Differences Between Custom and Precast Pools

Installation Timelines and Processes

Custom pools need weeks or months to build due to on-site construction. Precast pools are installed in days or weeks as they are pre-made and delivered ready for placement.

Design Flexibility and Customisation Options

Custom pools allow full design freedom, while precast pools come in fixed shapes and sizes with limited personalisation.

Costs, Durability, and Maintenance Requirements

Precast pools cost less upfront but offer limited design options. Custom pools are more expensive initially but may add long-term value due to unique designs. Both types are durable but vary in maintenance needs depending on materials and installation quality.

Step-by-Step Guide to Installing a Custom Plunge Pool

Step 1: Site Assessment and Excavation

Professionals inspect the site to evaluate soil stability, slope, and access. Once approved, excavation begins to prepare the foundation for the concrete plunge pool.

Step 2: Custom Design Approval and Material Sourcing

A final design is selected, including dimensions, finishes, and additional features. Materials are sourced to ensure strength and durability.

Step 3: Steel Reinforcement, Plumbing, and Concrete Pouring

Steel reinforcements are added for structure. Plumbing and electrical systems are installed, followed by concrete pouring to shape the pool.

Step 4: Curing, Finishing, and Landscaping

The concrete cures over several weeks. Finishing touches, such as tiling or painting, are added. Landscaping completes the area for a polished look.

Step-by-Step Guide to Installing a Precast Plunge Pool

Step 1: Selecting Your Pool Design and Dimensions

Choose a pre-made pool design that offers flexibility in design options. The pool is built in a factory to meet high-quality standards.

Step 2: Site Preparation and Crane Access Planning

Prepare the site by leveling the ground and clearing space for crane placement. Ensure easy access for smooth delivery.

Step 3: Delivery, Placement, and Connection of Utilities

The pool is delivered and placed using a crane. Plumbing and electrical systems are connected to complete the setup.

Step 4: Final Touches, Including Decking and Landscaping

Decking, paving, and landscaping are added to enhance the pool’s usability and appearance.

Sustainability Insights: Custom vs. Precast Pools

Resource Usage in Manufacturing and Installation

Custom Pools:
Custom pools need more materials, like concrete and steel, which are delivered to the site. On-site work creates additional waste from cutting and shaping these materials.

Precast Pools:
Precast pools are pre-manufactured pools made in factories, reducing waste and improving resource efficiency. The entire pool is transported as a single unit, lowering on-site material use

Impact of Site Disruption and Excavation

Custom Pools:
Excavation for custom pools can disturb plants, trees, and soil. The extended construction process can impact the surrounding area significantly.

Precast Pools:
Precast pool installation is quicker and less invasive. Minimal excavation is required, preserving the property’s natural environment.

Maintenance and Long-Term Durability

Custom Pools:
Custom pools often need more chemicals for cleaning and larger filtration systems, increasing upkeep and energy costs.

Precast Pools:
Precast pools are easier to maintain due to their smooth surface, which resists algae. This reduces cleaning time and the need for chemical treatments.

Potential Repair Needs and Associated Costs

Custom Pools:
Custom features like tiles or lighting may require frequent repairs. Structural fixes can be costly due to the unique design.

Precast Pools:
Precast pools are built to standard specifications, making repairs simpler and cheaper. However, improper installation when installing a plunge pool might lead to minor issues, like cracks or settling

Long-Term Durability of Custom vs. Precast Pools

Custom Pools:
A well-built custom pool can last decades. Its durability depends on high-quality materials and precise construction.

Precast Pools:
Precast pools are durable due to their uniform design. The one-piece construction reduces the chance of leaks or structural damage.

Frequently Asked Questions

1. Can a precast plunge pool be installed on sloping or uneven ground?

Yes, precast plunge pools can be installed on sloping or uneven ground with proper preparation. Excavation and levelling may be required to stabilise the base. In some cases, retaining walls or structural supports may be added to ensure stability on sloped sites.

2. What are the site preparation requirements for precast plunge pools?

Precast pool site preparation includes levelling the ground, ensuring proper drainage, and clearing any obstructions for crane access. A stable foundation is essential to support the pool’s weight. Soil testing may also be done to check for ground stability. These steps are crucial for a secure and smooth installation.

3. Do precast plunge pools require a crane for installation?

Yes, precast plunge pools need a crane for placement. The pool arrives as a single unit and is lifted into position by the crane. Planning for crane access ensures the process is quick and efficient, avoiding delays or unexpected costs.

4. Are there any hidden costs in custom plunge pool installations?

Hidden costs in custom installations may include unexpected excavation work, design adjustments, or weather-related delays. Extra expenses for permits, specialised materials, or professional labour can also arise. Partnering with an experienced contractor helps anticipate and control these costs for a more predictable project.

5. Which type of plunge pool is better for small backyards?
