Traditional swimming pools come with high costs, large footprints, and construction cycles of several months, discouraging many homeowners. In recent years, a prefabricated solution known as a small container pool has gained huge popularity. It adopts the steel frame of new or retired shipping containers. Welding, anti-corrosion treatment, interior finishing, and equipment pre-installation are all completed in the factory. After delivery to the site, hoisting, pipe connection, and water filling commissioning can usually be finished within one day. Take the standard 20FT model as an example: its empty weight is around 2.2 tons, and total weight reaches 10~13 tons when fully filled with water. Its cost is only 1/3~1/2 of a conventional swimming pool. Flexible, durable, and stylish, this solution has become a popular choice for backyard upgrades, homestay supporting facilities, and villa landscape projects. Below, we will comprehensively cover purchasing tips for a small container pool from dimensions, material selection, installation, space matching, and frequently asked questions.

How to Choose Internal Materials for a Small Container Pool?
When purchasing a small shipping container pool, the liner material directly affects water quality, service life, and maintenance cost. Comparison of three mainstream options:
- PVC Pool Liner: Most popular in European & American markets, cost-effective with abundant color options (white, light blue, dark blue, grey, black, etc.). Easy maintenance, ideal for most residential users.
- Fiberglass: One-piece molding, acid & alkali resistant, high strength and good thermal insulation, yet slightly higher initial cost than PVC liner.
- 316 Stainless Steel: Top-tier anti-corrosion performance, especially suitable for coastal or humid environments. No liner replacement required, but comes at the highest price.
Recommendations: Choose PVC if you have a limited budget; prioritize 316 stainless steel for long-term use or salt chlorination systems; fiberglass balances performance and cost.
How to Select Installation Methods for a Small Container Pool?
An above ground shipping container pool supports three installation modes; select according to site conditions and landscape requirements:
- Above-ground Installation: Fastest solution, no excavation required. Ready for use right after hoisting. It can be relocated after draining water, the most budget-friendly option.
- Semi-recessed Installation: Embed 30%~70% of the pool height. Balances visual effect and integration with surroundings with moderate construction workload. We suggest reserving drainage channels and maintenance access.
- Fully Recessed Installation: The whole pool is buried underground, only the glass viewing window or deck surface exposed. The visual effect is identical to traditional swimming pools. Special attention must be paid to groundwater treatment, structural load-bearing, and equipment maintenance space.
Tip: Whichever method you adopt, a concrete base (or steel platform) is recommended to guarantee stability.
How to Perfectly Fit a Small Shipping Container Pool in Limited Backyard Space?
The 20FT small container pool occupies only around 13 square meters. Smart design can turn it into a courtyard highlight without looking abrupt:
- Exterior Decoration: Cover the pool with wooden slats, anti-corrosion timber, or stone cladding to weaken the industrial container look and match the style of your garden or patio.
- Utilize Viewing Windows: The standard large viewing window (2400×900mm) improves lighting and creates an underwater viewing experience. Bury most of the pool body underground with only glass exposed, which is the most favored modern style among European and American customers.
- Surrounding Deck: Build an anti-corrosion timber deck at the same height as the pool to form a leisure zone, while concealing the maintenance door and staircase.
- Color Matching: Pick exterior paint tones similar to your building facade or outdoor furniture (grey, dark blue, etc.), letting the pool naturally blend into the background.
Equipment Configuration & Intelligent Upgrade for Above Ground Shipping Container Pool
Optional extra functions for small container pool based on your demands:
- Filtration & Sanitation: Quartz sand filter as standard; salt chlorinator optional to cut chemical usage and deliver softer water.
- Constant Temperature System: Air source heat pump enables year-round swimming, highly recommended for homestays and all-season commercial projects.
- Intelligent Control: WiFi & mobile APP remote control, automatic water quality monitoring, low-voltage IP68 LED lights for safe operation.
- Automatic Cover: Optional electric roller cover to reduce heat loss and fallen leaf contamination.
FAQ About Small Container Pool
Below are answers to the 8 most common questions during selection and usage:
Q: Will it rust?
A: No. The steel structure undergoes sandblasting + Jotun primer + topcoat treatment, with a waterproof isolation layer inside. Main structure service life exceeds 20 years.
Q: Can sizes and colors be customized?
A: Yes. Length, width, depth, glass dimensions, and equipment are all customizable. Regular colors include white, blue, grey, black; custom RAL color codes are available.
Q: What is the weight? Weight when fully filled?
A: 20FT: empty weight 2.2 tons, 10~13 tons full of water. 40FT: empty weight 5 tons, 24~26 tons full of water. Confirm ground bearing capacity before installation.
Q: Can SPA jets or counter-current swimming system be added?
A: Yes. Massage nozzles, bubble system, constant temperature system, or custom endless counter-current unit can be equipped for fitness training.
Q: Can it be installed on the coastline or rooftop?
A: Coastal installation requires upgraded anti-corrosion grade and 316 stainless steel accessories. Rooftop installation must be verified by structural engineers for full load capacity.
Q: How long does installation and commissioning take?
A: 1 hour for hoisting, 2~4 hours for pipe connection, half a day for water filling & testing. Normally completed within one day in total.
Q: Can it be relocated again?
A: Yes. Simply drain the water and lift the pool. This is a core advantage of container pools compared with traditional concrete pools.
Q: Is the operating cost high?
A: The circulation system consumes roughly 2~5 kWh daily. Heating with a heat pump consumes about 10~30 kWh/day (heat pumps save 60~80% power compared with electric heating). It features higher water circulation efficiency and more energy-saving filtration than traditional pools.
