How Many Porta-Potties Do You Really Need?

You’ve booked the band, ordered the catering, and sent out the invites. But there’s one key question that stumps even the most seasoned event planner or contractor: How many porta-potties do we actually need?

One Toilet, Ten Guests? Let’s Do the Porta-Pottie Math

At Dalton Jodrey Plumbing & Heating, we get this one a lot. Whether you’re organizing a summer wedding in Mahone Bay, a block party in Liverpool, or setting up a construction site in Bridgewater, the answer depends on several important factors—and we’re here to help you figure it out.

Here’s a quick breakdown to make sure your guests (or crew) are taken care of—no waiting lines, no awkward moments.

For Events: The 1-to-50 Rule

A good general rule is one portable toilet for every 50 people for events lasting up to 4 hours. If your event is longer or includes alcohol (hello, backyard weddings and beer tents!), you’ll want to bump that up.

Here's a quick guide:

• 1–50 guests = 1 unit

• 51–100 guests = 2 units

• 101–150 guests = 3 units

• Add 1 additional unit per 50 guests after that

And if your event runs over 4 hours? Add 15–25% more units.

For Job Sites: Compliance Matters

If you're running a construction site in Queens or Lunenburg County, the rules are a little different. Nova Scotia Occupational Health & Safety guidelines recommend:

• 1 toilet per 10 workers

• Toilets should be located within a reasonable distance from the worksite

At minimum, we recommend a service every two weeks depending on crew size and usage.

We offer durable, no-fuss portable toilets that stand up to heavy use and include handwashing options for hygiene on the job.

Add-Ons That Make a Difference

When in doubt, consider the extras:

• Units with sinks for more sanitary events or food-focused gatherings

• Flushing porta-potties for weddings and VIP setups

• Pink portable toilets to match your event theme or just add personality
