HOW MANY UNITS DO YOU NEED?

1 unit per 10 workers

Based on a standard 40-hour work week. OSHA requires one toilet for every 20 workers, but we recommend 1 per 10 for better comfort and compliance.
Example: A crew of 25 workers needs 3 portable toilets.

FOR CONSTRUCTION SITES

Perfect for weddings, graduation parties, birthday celebrations, and corporate gatherings.
Example: A 150-person wedding needs 3 portable toilets.

FOR EVENTS (4 HOURS OR LESS)

1 unit per 50 guests

FOR LONGER EVENTS (8+ HOURS)

1 unit per 35 guests

All-day festivals, concerts, and multi-hour outdoor events require more capacity.
Example: A 200-person all-day festival needs 6 portable toilets.

 IMPORTANT FACTORS TO CONSIDER:

If you're serving beer, wine, or cocktails at your event, plan to add 1-2 extra units. People use restrooms more frequently when alcohol is involved.

At least one ADA-accessible unit is required for any event open to the public. These units are also great for families with small children and anyone needing extra space.

Women typically need restrooms more frequently than men. If your event has a female-heavy guest list, consider adding extra units.

What should I do to prepare the site for delivery?

What should I do to prepare the site for delivery?

For smooth delivery, have ready:
Level ground: Portable toilets need relatively flat, stable surfaces. Slight slopes are okay, but avoid steep inclines.
Clear access: Our delivery truck needs to get within 50 feet of placement location. Remove obstacles, low branches, or debris from the path.
Placement location marked: Flag or mark where you want units placed. For multiple units, show us the layout.
For events: Avoid placing units:

Too close to food service areas (keep 50+ feet away)
In guest sight lines or photo backgrounds
Where they block emergency access

For construction sites: Place near work areas but away from:
Heavy equipment paths
Material delivery zones
Excavation areas

Ground conditions:
Solid ground is best: Grass, gravel, dirt, or concrete
Avoid soft/muddy areas: Units can sink or tip
Frozen ground (winter): No problem—we have stabilizers

You don't need to:
Provide power or water hookups
Dig holes or prepare foundations
Haul units yourself—we handle everything

Questions about your site? Text or email us photos before delivery and we'll confirm the setup will work. Call 406-822-4495.
