The sidewalls of a restroom trailer serve as the structural exterior, providing support, insulation, and protection for the interior plumbing and electrical systems. They are typically constructed from durable materials like aluminum, fiberglass, or composite panels to withstand weather conditions and frequent transport.
Sidewalls also house essential components such as ventilation systems, access doors, and service panels for maintenance. In some designs, they include connection points for water, electricity, and waste disposal. Additionally, sidewalls contribute to the trailer’s aesthetics and branding, often featuring graphics, logos, or decorative finishes.
