October 2026 wedding: do we need heated restroom trailers?

Yes, for an evening wedding in Chicago in late October, you should rent heated restroom trailers to keep guests comfortable. The temperature can fall into the 40s, and standard trailers without heat will feel cold, especially for guests in formal attire. A restroom trailer with heating provides a warm, comfortable environment.

The heating system in a restroom trailer is typically electric and requires a power source, which is an important setup factor. You will need to arrange for a generator for restroom trailers if the venue lacks sufficient outdoor electrical outlets. This need for a generator and the more complex heating unit are the primary factors that increase the cost compared to a standard unheated trailer.

For 150 guests at an eight-hour event with an open bar, a good starting point is to plan for more than the basic guideline of one unit per 50 to 75 people. You should also include at least one ADA-compliant portable toilet if you are clustering multiple units, as required by the ADA 5 percent cluster rule. Confirm with your rental company that the units will be placed on level ground for stability.
