40 Ft Container Pool (CW-40-FT-CONTAINER-POOL)

A 40ft shipping container in used condition — in service and structurally sound. Chosen for general cargo and secure storage. Every unit is inspected before it leaves our yard, so the grade below is what you will actually receive.

A 40ft container pool is a practical way to create a large, modern swimming area without starting with a conventional concrete pool. By repurposing a structurally sound shipping container, the design combines a strong steel structure with the flexibility to add a custom pool finish, filtration system, heating, lighting, decking and other features.

Because the pool is built around a 40ft container, it has a long, narrow footprint that can work particularly well in backyards and other outdoor spaces where a conventional pool layout may not be ideal. It also gives you plenty of room for swimming, relaxing and entertaining.

40ft Container Pool Design

The rectangular shape gives a container pool its distinctive industrial look. The exterior can be painted or finished to complement the property, while decking, paving, landscaping or seating can soften the steel structure and create a more finished outdoor living area.

A custom deck can also extend around part of the pool, creating space for loungers, seating and access to the water. For a more contemporary appearance, buyers can consider features such as glass panels, integrated lighting or a minimalist surrounding deck.

Sustainable Pool Alternative

Using a repurposed shipping container gives the project a second use for an existing steel structure instead of starting with an entirely new pool shell. Steel is also a durable and recyclable material, making the container-based approach attractive to buyers who want a different approach to outdoor construction.

However, sustainability depends on the complete project, including the pool equipment, heating system, lining, insulation and materials used for the surrounding deck and landscaping. Choosing efficient equipment and a suitable pool cover can also help reduce ongoing energy consumption.

Space and Dimensions

The underlying 40ft shipping container measures approximately 40ft long and 8ft wide externally. The standard internal dimensions are approximately 39ft 5in long by 7ft 8in wide, although the final usable pool dimensions will depend on the conversion.

The pool depth can be designed around the intended use, subject to the engineering and construction requirements of the finished pool. A recreational pool, family pool and deeper swimming pool can require different specifications, so the intended use should be established before fabrication begins.

Approximate container dimensions

These are approximate dimensions for the underlying container. Pool construction reduces the available internal space, and exact measurements can vary slightly between container manufacturers.

Above-Ground or Partially Recessed Installation

A 40ft container pool can be installed above ground, partially recessed or incorporated into a more extensive landscaping project, depending on the site and design.

An above-ground installation can reduce the amount of excavation required, while a partially recessed installation can make the pool blend more naturally into the surrounding landscape. The appropriate approach depends on ground conditions, access, drainage, structural support and local requirements.

A filled pool places a significant load on the supporting surface, so the foundation or support system should always be designed for the completed installation rather than simply the empty container.

Custom Features and Finishes

The container is only the starting point. The finished pool can be configured around the way you intend to use it.

Waterproof Interior

A suitable pool lining or interior finish creates the waterproof swimming surface and provides the appearance you want. Available finishes can vary depending on the pool builder and specification.

Heating

A pool heating system can extend the swimming season and make the water more comfortable. The right system depends on the pool volume, climate, desired water temperature and available energy source.

Filtration

A properly sized filtration and circulation system is essential for maintaining clean, clear water. Equipment should be selected according to the finished pool volume and expected usage.

Lighting

LED lighting can improve visibility after dark while adding an attractive feature to the finished pool. Lighting can be combined with surrounding deck and landscape lighting for a coordinated appearance.

Decking

Wood, composite decking, paving and other exterior finishes can be used around the pool. A well-designed deck can provide space for seating, sunbathing and safe access while helping integrate the container into the garden.

Is a 40ft Container Pool Suitable for Your Property?

The long footprint makes a 40ft container pool particularly interesting for properties with a narrow or elongated outdoor area. It can provide considerably more swimming length than a smaller container pool while retaining the relatively compact width of the container.

Before ordering, consider the complete installation rather than just the pool itself. You will need enough room for delivery, unloading, installation, equipment access and ongoing maintenance.

Access should be measured from the road or delivery point all the way to the proposed installation area. Gates, turns, overhead cables, trees and other obstacles can affect whether a 40ft container can reach the site.

Used Container Condition

This pool is based on a used 40ft shipping container that has previously been in service. It is wind and watertight, with no holes, working door seals and an intact roof.

As with any used shipping container, surface rust, dents, scratches and previous owner markings can be present. These are normal signs of previous use and do not necessarily affect the container's suitability for conversion.

Every unit is inspected before leaving our yard. If you are purchasing the container specifically for a pool conversion, we recommend confirming the structural condition and proposed modifications before fabrication begins.

Frequently Asked Questions

How big is a 40ft container pool?

The underlying container is approximately 40ft long and 8ft wide externally. The finished swimming area will be smaller depending on the waterproof lining, insulation, steps, seating and other internal features.

Can a used shipping container be converted into a swimming pool?

Yes. A suitable used container can provide the structural shell for a pool conversion. It needs to be inspected and appropriately prepared before installing the waterproof interior, plumbing, filtration and other pool systems.

Can a 40ft container pool be installed above ground?

Yes. Above-ground installation is one possible configuration. The supporting foundation must be suitable for the substantial weight of the container and water when the pool is full.

Can the depth of a container pool be customized?

The finished pool design can be customized, but the achievable depth depends on the engineering, structural modifications, pool lining and installation method. Discuss the intended depth with the pool builder before fabrication.

Can I add heating and filtration?

Yes. Heating, filtration and circulation systems can be incorporated into a container pool. Equipment should be correctly sized for the finished pool volume and intended usage.

Can I add a deck around a 40ft container pool?

Yes. Decking is a popular way to create a finished appearance and provide space for seating and access around the pool. Wood, composite and other suitable exterior materials can be considered.

Does a container pool require a foundation?

The pool needs adequate structural support. The exact foundation or support system depends on the site, installation method, ground conditions and finished pool design. A qualified professional should determine the appropriate solution.

How much does a 40ft container pool cost?

The total price depends on the container, pool conversion, waterproofing, filtration, heating, insulation, lighting, decking, delivery and installation. Request a quotation based on your preferred specification and delivery location.

Dimensions and capacity

Internal dimensions are approximately 39 ft 5 in × 7 ft 8 in × 7 ft 10 in (12,032 × 2,350 × 2,393 mm), giving 2,390 cu ft (67.7 m³) of usable space, with double doors at one end. These are the standard figures for a 40ft container; exact internals vary slightly by manufacturer.

Condition

This is a used container that has been in service. It is wind and watertight — no holes, working door seals, an intact roof — but it shows its history: surface rust, dents and previous owner markings are normal and do not affect how it performs.

What it is good for

This unit is commonly used for general cargo and secure storage. Doors, windows, insulation, electrics and paint can all be added before it ships — it is cheaper and neater to specify a conversion while the container is still in our yard than to modify it on your site afterwards.

Standards and inspection

Containers intended for international shipping carry a valid safety approval plate under the Convention for Safe Containers, administered by the International Maritime Organization. Condition grades such as cargo-worthy follow the inspection criteria published by the Institute of International Container Lessors. If you need a unit for shipping rather than static storage, tell us and we will confirm its plate before dispatch.

Delivery

Delivery is quoted against your site access rather than published as a flat rate, because haulage for a container depends on the distance, the approach and whether a crane is needed. Most deliveries use a tilt-bed truck, which needs a clear and reasonably level run about twice the container length. We price it before you commit.
