Cold weather doesn't have to stop your project or event. Here's what you need to know about portable restrooms in winter conditions.
How Cold Weather Affects Portable Restrooms
Standard portable toilets can operate in temperatures down to about 20°F (-7°C). Below that, several issues arise:
- Chemicals freeze: The sanitizing solution can solidify
- Waste freezes: Making pumping impossible
- Plastic becomes brittle: Risk of cracking
- Worker discomfort: Unheated units see less use
Winterized Units: What's Different
We offer cold-weather packages with special features:
- Antifreeze solution: Won't freeze in sub-zero temps
- Insulated walls: Retains some heat
- Solar-powered lighting: For short winter days
- Heated units: Propane heater keeps interior above freezing
- Heat lamps: Optional add-on for luxury trailers
Cold Weather Pricing
| Service | Additional Cost |
|---|---|
| Antifreeze treatment | $15-25/unit |
| Insulated unit upgrade | $25-50/unit |
| Propane heater (per day) | $35-75/unit |
| Daily heated trailer | $150-250 additional |
Site Preparation for Winter
Help us serve you better in cold weather:
- Clear snow: Keep access path to units clear
- Salt/sand walkways: Prevent slips
- Mark unit locations: Stake flags so they're visible in snow
- Plan for plowing: Don't block service access
- Provide windbreaks: Canopies reduce wind chill
Winter Event Tips
Outdoor Winter Events
- • Consider heated trailers instead of standard units
- • Place units in sheltered areas out of direct wind
- • Add lighting — it gets dark early
- • Consider more units — people use them faster in cold weather
- • Schedule more frequent service to prevent freezing issues
Construction in Winter
Building doesn't stop when it snows:
- OSHA still applies: Workers need accessible restrooms
- Insulated units help: But heated units are better
- Service more often: Prevents waste from freezing in tank
- Check daily: Monitor for any freezing issues
What Happens If Waste Freezes?
If a unit freezes, don't panic:
- Unit cannot be serviced until it thaws
- We may need to bring a replacement unit
- Thawing may take 24-48 hours naturally
- Additional charges may apply for emergency service
