What Are Modular Restroom Containers?

Our modular restrooms are typically built out of high-quality shipping containers that are modified to include full restroom facilities - partition walls, toilets, showers, urinals, sinks, washbasins and changing rooms. This approach offers portable buildings that are a durable, flexible and cost-effective solution for environments and projects where traditional permanent construction is impractical or too slow.

Frequently Asked Questions

  • How long does it take to deliver and install a restroom container?

    Shipping containers are inherently designed for transport. Born from the necessity to ship goods across oceans and continents, these steel boxes are crafted to be moved efficiently. When transformed into homes, they retain this essential quality. Unlike traditional homes, container homes can be easily loaded onto a truck or a ship, ready for their next destination. Once your land is cleared and infrastructure is restored, your shipping container home can be easily moved to your original lot or a new location.


  • Can the restroom container be moved later?

    The straightforward foundation requirements of container homes allow for rapid deployment. Your home can be built off site and then delivered to your property, set on various temporary foundations so it is functional and hooked up to utilities in a matter of days from delivery.

  • Are your units ADA compliant?

    Yes, we do offer designs and builds to meet ADA (Americans with Disabilities Act) requirements, including accessible stalls, door widths, and ramps.


  • Do you offer off-grid solutions?

    Certainly — we can integrate solar power, battery storage, and can hook up to grey water systems, and self-contained waste systems to support remote or unelectrified sites.
