How Many Portable Toilets Do You Need?
Restroom trailers pack multiple stalls, sinks, and (on larger sizes) urinals into one unit — often fewer deliveries than the same capacity in standalone porta potties.
Alcohol service increases restroom usage — we'll adjust your count automatically.
Texas Johns offers Standard porta potty rentals, luxury restroom trailers, and ADA/Handicap units — plus hand washing stations.Contact Texas Johns to confirm pricing and how many portable toilets you will need.
Longer projects benefit from a regular pump-out schedule rather than added units.
Most job sites run Standard units. Restroom trailers are worth considering for long-term projects with office staff on site.
