• Interior partitions for separate workspaces
• Restrooms, plumbing, and running water
• Custom electrical outlets and solar power options

8. Do container offices have restrooms?

Dry Box office containers do NOT have restrooms. Some custom models come with built-in restrooms, but they are typically an add-on feature. Let us know if you need a unit with plumbing or a nearby portable restroom.

9. Do mobile container offices have electricity?

Yes, they are pre-wired for lighting, outlets, and HVAC. Shipping container offices require 240V, 100-amp, 60-Hz single-phase power. They can connect to a power source via standard hookups or generators. A licensed electrician should be used to complete the installation.

10. How do I get the Internet in my container office?

Most portable office spaces use a cellular hotspot device for the Internet connection. And services like Starlink now offer high-speed Internet to almost every remote region in the world. However, each office container also has a conduit passthrough to bring network or other cabling into the office.
