- Water capacity and weight: water capacity about 10 cubic meters (10,000 liters), empty pool weight about 2.2 tons, total weight when fully loaded about 10-13 tons. The foundation design must be constructed according to this load-bearing standard.
- Transport compatibility: external dimensions comply with international 20-foot standard container specifications, can be shipped to major global ports via standard container ships, and one 20GP can load the whole unit.
20ft Swimming Pool Installation: What to Prepare Before Delivery
- Foundation preparation: three recommended foundation options—reinforced concrete foundation, steel structure platform, or compacted gravel foundation. Key requirements: level error ≤5mm, stable foundation with no settlement risk, meeting the 10-13 ton full-load weight requirement.
- Power supply reservation: bring the power line to the pool installation site in advance. Standard voltage 220V/50Hz, with support for customization according to the destination country (USA 120V/240V/60Hz, Australia 240V/50Hz, etc.).
- Water supply and drainage piping: pre-install water inlet and drainage pipe connections, ensuring alignment with the pool equipment compartment.
- Hoisting conditions confirmation: confirm that a crane can reach the installation site, with no obstacles such as overhead power lines or low tree branches nearby.
- Installation timeline: hoisting and positioning take about 1 hour; water/electricity connection and system commissioning take about half a day to one day, then the pool is ready for filling and use.
Container Swimming Pool Cost: Key Factors Affecting Price
- Size specifications: in the container swimming pools for sale market, prices for the 20ft, 30ft, and 40ft models increase progressively. The 20ft, being the smallest and most economical to transport, is the entry-level first choice.
- Internal material upgrades: PVC film is the standard configuration; upgrading to fiberglass lining or 316 stainless steel lining adds cost, but corrosion resistance and service life are also improved accordingly.
- Equipment configuration options: optional heat pump heating system, automatic roller cover, counter-current swimming system, SPA massage system, salt chlorine disinfection system, etc. Each option affects the final container swimming pool cost figure.
- Shipping cost: the whole unit can be shipped by sea in a 20GP standard container. Freight costs depend on the distance to the destination port and current shipping rates. The 20ft model has the lowest logistics cost among the three sizes.
- Customization requirements: custom items such as exterior color, glass size, interior decoration, and corporate logo all affect the quotation. YG supports providing formal project-based quotations upon request.
FAQs About the 20ft Swimming Pool
Q: Will this small container pool rust?
No. The steel structure is protected by sandblasting, Jotun anti-rust primer, and topcoat in three layers. The internal PVC waterproof system completely isolates water from the steel structure, eliminating rust risk.
Q: Is the glass viewing window safe?
Yes. It uses laminated tempered glass, fully designed for long-term water pressure loads, with dual sealing via special structural adhesive and a mechanical fixing system. Under normal use, it will not break or leak.
Q: Can it maintain a constant temperature?
Yes. The optional air-source heat pump system saves 60%-80% energy compared to traditional electric heating, suitable for year-round commercial projects or family use in colder winter regions.
Q: Is water quality maintenance complicated?
The standard quartz sand filter system is easy to maintain and has low operating costs. An optional salt chlorine disinfection system reduces chemical use, making water softer and maintenance easier.
Q: Does it support smart control?
Optional WiFi control system, mobile APP remote control, and automatic water quality monitoring are available, suitable for commercial scenarios like resorts and homestays that need remote management.
