Do self-storage containers have a water supply?

Sorry but the short answer is “No, they don’t.” Self-storage containers are designed for exactly that: storage!

In addition, they do not have mains drainage although some suppliers — including the Space Program — do offer storage units with a 13 amp power supply in some of their locations .

However, that does not make them suitable as somewhere to live. You can find out more here about why containers can’t be used as accommodation.
