Description
A 20ft Container Pool is a creative and modern swimming pool made by converting a used or new 20ft shipping container. It offers a sleek, industrial-chic design with a quicker and often more affordable installation than traditional in-ground pools.
What is a Container Pool?
It’s exactly what it sounds like: a standard 20ft shipping container (8ft wide, 8.5ft high) is professionally modified into a fully functional swimming pool. The steel structure is made watertight, fitted with a filtration system, and often finished with a pool liner or interior coating.
Key Dimensions (Approximate):
-
Length: 20 ft (6.1 m) – Usable water length is slightly less.
-
Width: 8 ft (2.44 m)
-
Water Depth: Typically 4.5 ft to 5.5 ft (1.4 m – 1.7 m), but can be customized.
-
Water Volume: Roughly 5,000 – 6,500 gallons, depending on final depth.
Benefits of a Container Pool
-
Faster Installation: Can be ready in weeks, not months. The shell is delivered pre-fabricated.
-
Cost-Effective: Often 30-50% less expensive than a comparable in-ground concrete pool.
-
Modular & Portable: In theory, it can be moved or relocated, unlike a traditional pool.
-
Modern Aesthetic: The sleek, rectangular shape fits contemporary garden designs.
-
Strong & Durable: Made from corrosion-resistant Corten steel, built to withstand harsh environments.
Key Components & What’s Involved
Turning a container into a pool requires professional conversion. Here’s what’s included:
-
The Structure: A one-trip or wind/watertight 20ft container.
-
Waterproofing: A full interior pool liner (most common) or a spray-coated sealant.
-
Filtration System: Sand filter, pump, skimmer, and return jets—same as a traditional pool.
-
Reinforcement: The container may need internal bracing to counteract the water pressure, especially if partially buried.
-
Finishing: External painting, decking cutouts, and steps or ladder installation.
Important Considerations & Challenges
Before you get excited, know the full picture:
-
Site Access & Delivery: You need a clear, wide path for a flatbed truck and a crane to place it.
-
Ground Preparation: Requires a perfectly level and engineered base, often a reinforced concrete pad.
-
Burial vs. Above-Ground:
-
Above-Ground: Easier and cheaper to install. May require safety fencing per local code.
-
Partially Buried: More aesthetic but requires serious excavation, drainage, and engineering to prevent collapse.
-
-
Regulations & Permits: You will need building permits. Local zoning laws may restrict placement.
-
Ongoing Costs: Same as any pool: chemicals, electricity for the pump, water, and maintenance.
Step-by-Step: How to Get One
-
Research & Design: Find a specialized container pool converter. Decide on features (depth, windows, decking, color).
-
Site Check & Permits: The company will often help assess your site and guide permit applications.
-
Preparation: Level your site and pour the concrete base or prepare the excavation.
-
Conversion & Delivery: The company modifies the container off-site, then delivers and places it with a crane.
-
Installation & Hookup: The pool is connected to the filtration system, filled, and treated.
Container Pool vs. Traditional Pool
| Feature | 20ft Container Pool | Traditional In-Ground Pool |
|---|---|---|
| Installation Time | Weeks | 3-6 Months |
| Upfront Cost | $$ (Lower) | $$$$ (Higher) |
| Design Flexibility | Limited to rectangular shape. | Highly customizable (any shape, size, depth). |
| Durability | Very high (steel structure). | High (concrete/gunite). |
| Resale Value Impact | Novelty can be a pro or con. | Generally adds value. |
