Whether you’re searching for a connex box pool or researching connex swimming pools, this guide covers everything you need to know.

What Are Connex Swimming Pools?

A connex swimming pool is exactly what it sounds like: a real swimming pool made from a repurposed steel shipping container (also called a Conex box). These are the same large metal containers you see stacked on ships and trains.

To create a connex box pool, builders:

  • 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
