What factors make a restroom trailer rental more expensive?

A restroom trailer rental is more expensive due to its features, setup needs, and capacity. The number of stalls is the primary cost driver; a four-station trailer costs more than a two-station one. High-end features like climate control (air conditioning and heating), premium finishes, and sound systems add significant cost. The size of the fresh water tank and gray water tank also affects price, as larger tanks require a heavier chassis and reduce the need for mid-event service. Delivery fees vary based on the trailer's weight and setup complexity. A heavier, multi-axle trailer requires a larger truck for towing. Setup complexity, like the need for precise leveling on soft ground or a longer distance to hook up power and water, adds labor time. For your 150-guest wedding with a six-hour dinner and open bar, the industry units per person guideline suggests more capacity is needed than for a shorter event without alcohol, which may explain why a larger, more equipped trailer was quoted.
