This 20ft container swimming pool is a new, purpose-built pool unit constructed from high-grade Corten weathering steel with a sleek black exterior finish. At 20ft in length with a 4ft water depth and a capacity of approximately 4,500 US gallons (17,034 litres), it is the most compact option in our container pool range — suited to smaller residential backyards, courtyard installations, rooftop terraces, and properties where a 30ft or 40ft pool cannot be accommodated. Despite its smaller footprint, it provides a full 4ft depth and 20ft swim length, making it a functional lap pool for fitness use as well as a leisure and entertaining feature.

The Corten steel construction develops a stable surface oxide layer over time, providing long-term corrosion and weather resistance without ongoing maintenance to the exterior. The advanced integrated filtration system is included as standard, maintaining water clarity with minimal manual intervention. Entry into the pool is customisable at time of order — choose between built-in steps integrated into the pool structure or an exterior ladder depending on your site layout and aesthetic preference. The unit is compatible with both saltwater and freshwater/chlorine systems — if a saltwater configuration is intended, confirm interior lining specification with JK Shipping LLC before ordering, as Corten steel requires appropriate internal waterproofing for saltwater use.

Optional add-ons available at time of order include an energy-efficient heating system for year-round use, LED underwater lighting with customisable colour settings for evening use, resistance swim jets for lap training and aquatic fitness, and decking or surround options in timber, composite, or stone. None of these extras are included in the base price — specify required options at time of order to receive an itemised quotation.

The unit arrives fully constructed and requires crane placement onto a prepared level base — a reinforced concrete slab is strongly recommended. Plumbing connection for water fill, waste, and filtration return, and any electrical connection for filtration pump, heating, or lighting must be completed on site by licensed contractors. Pool installations in the USA are subject to local building permits, property setback requirements, and pool fencing or barrier laws in most states and counties. Confirm all permit and compliance requirements with your local authority before ordering. For reference, see the International Code Council building standards reference.
