Information on Restrooms
A general rule of thumb is 1 restroom stall per 50 guests for a standard 4-hour event. However, factors like event duration, alcohol service, and a higher ratio of women to men can significantly increase that number. Use our free Event Restroom Calculator above to get a precise recommendation for your specific event.
Yes. Alcohol consumption increases restroom usage by approximately 30–40%. If your event includes an open bar or significant alcohol service, you should plan for additional stalls and handwashing stations beyond the standard recommendation.
Yes. Women statistically require more time per restroom visit than men. If your event has a higher percentage of female attendees — such as a bridal shower, wedding, or women’s conference — you should increase your restroom count accordingly to avoid long lines and guest frustration.
A portable restroom (port-a-potty) is a self-contained single unit, typically more affordable and suitable for casual or outdoor events. A restroom trailer is a climate-controlled, multi-stall unit with running water, flushing toilets, and interior lighting — better suited for weddings, corporate events, and upscale occasions.
The standard recommendation is at least 1 handwashing station for every 5–6 restroom stalls, or roughly 1 per 200–300 guests. Events with food service or health-sensitive environments may require more.
We recommend booking at least 2–4 weeks in advance for standard events, and 4–8 weeks ahead for peak seasons (spring and fall in Houston) or large events over 500 guests. Early booking ensures equipment availability and allows time for site logistics planning.
Yes. Houston Tents & Events offers ADA-compliant portable restrooms and restroom trailers to accommodate guests with disabilities. ADA units are larger, include grab bars, and meet accessibility requirements for public events.
