How many portable toilets does a film crew need?
It depends on the busiest day's headcount, the length of the shooting day and how many spots you are filming in. There is no single film-set ratio on this site. Give the provider your call sheet numbers and they will suggest a bank for each spot.
Productions often ask for a ratio, and the honest answer is that it comes from the people on your call sheet. The City of Houston special-event sheet asks event producers for 1 toilet per 300 persons, but that is written for permitted events on city property, not for a crew working a closed set. Do not borrow a number that was written for a crowd and apply it to a crew of forty.
If your production's safety coordinator, insurer or location agreement names a ratio, hand the number to the provider as written. If it does not, count people at their peak, count the spots where they gather, and order a bank at each spot. A crew that must walk across a lot for every break loses time.
Cast and background change the math. A day with sixty background performers can double the headcount without adding a single crew member, and those people sit in holding for hours. Tell the provider the holding location and the hours, and let them work out the bank.
Where should portable toilets go on a film location?
Put them where a delivery truck can reach, on flat ground, away from the camera and the microphone, and close enough to base camp that crew do not wander across the set. Ask the provider for placement that keeps the units out of frame and out of earshot.
Think of the location as three zones. The set is where the camera points, base camp is where trucks, tents and catering sit, and holding is where cast and background wait. Each zone wants its own units, because a restroom trip from holding to a far-off bank pulls people through the shot.
Sound is a real concern. A door that slams in the middle of a quiet take can cost a take, and a unit set just outside a window can be heard on a boom. Place units downwind and out of line of sight where you can, and warn the sound team where they are.
Ground matters as well. Tell the provider what the surface looks like, because Houston rains can turn an unpaved lot soft quickly. A scout photo of the actual spot saves a phone call on delivery morning.
What changes when you shoot in Houston summer heat?
Heat drives restroom use up and makes a closed unit uncomfortable. Houston has issued repeated heat advisories with temperatures at or above 105 degrees Fahrenheit and a heat index near 112, so plan for more frequent servicing, shaded placement and water for the crew.
Hot weather changes the schedule of a day. Crew drink more, take more breaks and use the restrooms more often, so a bank that looked right for a spring shoot can run short in July. If your shoot falls in the hottest months, tell the provider the dates and ask whether more units or more frequent servicing suit the job.
A standard unit heats up in the sun. Where the location allows, ask for placement in shade or beside a building, and tell the crew to expect warm interiors by mid-afternoon. For principal cast and anyone who has to stay in costume, a restroom trailer with air conditioning is a comfort choice some productions make, subject to what the provider has free.
What does a Houston location shoot need to tell the provider?
Tell the provider the address or a map pin, the shoot dates, the daily call and wrap times, the headcount on your busiest day, the surface units will sit on and any access limits such as a gate code or a tight alley. Then confirm the removal day after wrap.
A clear brief at the start saves calls during the shoot. Include a contact who will actually answer on the delivery morning, the name of the location owner and any restrictions on where trucks may park. If the location is a street or park, mention that the production holds the permits so the provider can plan around the arrangement you already made.
The Houston Film Commission supports location shoots and permits, and permit requirements are handled between the production and the city or the property owner. Houston Porta Potty Rental does not obtain or approve film permits, and no provider can promise one. What a provider can do is supply the units, service them on a schedule you agree and remove them on the day you name.
