Family of five, no plumbing until spring 2027. One porta potty enough?

One standard portable toilet is not enough for a family of five for two years of daily living. A standard unit holds 50 to 70 gallons and is designed for intermittent use by workers or event attendees, not continuous household use. For a family of five, you will need at least two units to manage waste volume and reduce odor buildup between service visits.

Upgrade to a deluxe unit with a flushing toilet and sink or consider a restroom trailer for better hygiene and comfort. A restroom trailer provides multiple stalls, running water, and mirrors, but it requires level ground, electrical power, and more frequent servicing due to its fresh water and gray water tanks.

Service frequency depends on use. For a family of five with one standard unit, you would need service every three to four days to prevent overfilling and maintain cleanliness. With two units, weekly service may suffice. Heavier use, heat, and flushing units increase service needs. Discuss your usage with the rental company to set a realistic service schedule.

One standard unit can work for five people if you get it serviced twice a week instead of weekly. We lived through a gut job on our only bathroom with two adults and two teenagers and one unit on the driveway. Weekly service was rough by day five. Switching to two visits a week fixed most of it.

A few things helped us more than upgrading the unit:

• A deluxe unit with a sink, or a separate hand wash stand right next to the door. Kids actually wash when the sink is right there.
• A trash can inside the unit and a house rule that nothing but toilet paper goes in the tank. Wipes and paper towels are what made ours stink and plug up.
• Turn the door away from the street and put it where it gets afternoon shade. Heat makes the smell a lot worse.
• A battery lantern hanging inside for night trips.

For a job that runs this long, ask your contractor if they can set one temporary toilet on the existing drain line early in the job. If that can't happen, I'd skip the trailer since it needs power and water hookups you probably won't have mid demo. Watch how full the tank gets the first two weeks and set your service visit schedule from that.
