Ask about the actual equipment
Wider doors and interior space vary between models. Explain the access requirements for your event or worksite and ask for the specifications of the proposed unit. A photograph illustrates a product category; it does not confirm that a particular model meets every requirement of your location.
Check the route beyond the door
Loose gravel, a steep edge or a narrow gap between parked vehicles can make an otherwise suitable unit difficult to reach. Walk the proposed route from the entrance and main activity area. Consider surface stability, clear space at the door, lighting and any temporary cable covers.
If you are working with a venue or event organiser, have that person review the layout too. Equipment selection is only one part of an access plan, and this guide does not replace a project-specific accessibility assessment.
Keep accessible facilities available
Avoid placing stock, bins or barriers in the clear area after setup. Nominate someone to monitor the route while people are on site. When requesting a quote, describe both the cabin requirement and any washing station or trailer access needs so the proposed arrangement addresses them together.
