What Are Connex Swimming Pools?

Cut a section from the container side
Reinforce the structure (containers aren’t designed to hold water)
Add waterproof lining, insulation, and filtration
Install pumps, heaters, lighting, and decking
Key benefits of connex swimming pools:
| Benefit | Why It Matters |
|---|---|
| Affordable | Costs 40-60% less than in-ground pools |
| Fast installation | Set up in 2-4 weeks vs. 2-3 months for traditional pools |
| Eco-friendly | Repurposes retired shipping containers |
| Portable | Can move with you to a new home |
| Durable | Corten steel lasts 20+ years with proper maintenance |
| Space-saving | Fits narrow or urban backyards |
