When the cold season arrives, a question often arises among contractors, municipalities, and event organizers : can portable toilets really be used in winter ?

The answer is yes, provided you work with a supplier that has the equipment, expertise, and logistics suited to winter conditions. At Sanivac, portable toilet rentals don’t stop in the fall. Thanks to a specialized fleet, winterized units, and the largest inventory of temporary sanitary solutions, we provide reliable service 12 months a year, even during the harshest winters.

Why does winter pose a challenge for portable toilets ?

Winter brings a host of technical challenges. Sub-zero temperatures can cause liquids to freeze, make maintenance more complex, and reduce user comfort. Without the proper equipment, a portable toilet can quickly become unusable.

That is why using portable toilets in winter requires :

• properly winterized units,
• products designed to resist freezing,
• a maintenance fleet capable of operating in cold weather,
• proven on-site expertise.

At Sanivac, these elements are an integral part of our service.

Standard portable toilets adapted for winter

Contrary to popular belief, plastic portable toilets can be used in winter when properly prepared.

The standard portable toilets offered by Sanivac are winterized using:

• specialized antifreeze, preventing liquids from freezing,
• built-in heaters, maintaining a functional temperature inside the unit,
• an insulating cover, designed to retain heat and protect the toilet from extreme cold.

This combination helps maintain a usable, safe, and functional environment for workers or users, even in very cold weather.

A maintenance fleet designed for winter

The use of portable toilets in winter depends not only on the units themselves but also on maintenance capabilities. At Sanivac, our service trucks are adapted to winter conditions.

Our trucks :

• are housed in heated garages, which keeps the water at the proper temperature,
• are equipped with water heaters, preventing system freezing,
• can perform emptying, cleaning, and delivery even in the middle of winter.

Thanks to this logistics, we ensure uninterrupted service year-round. This allows us to rent, maintain, and replace plastic portable toilets 12 months a year, which is a major advantage for winter construction sites and projects.

An ideal solution for winter construction sites

On construction sites, access to sanitary facilities remains mandatory, even in winter. Winterized portable toilets provide a practical, cost-effective solution that complies with health and safety standards.

With Sanivac, contractors benefit from :

• units adapted to cold weather,
• regular maintenance despite weather conditions,
• reliable service, with no compromise on hygiene.

This approach allows construction sites to continue their operations without worrying about seasonal constraints.

More comfort in winter: restroom trailers and portable sanitation units

For projects requiring a higher level of comfort, Sanivac offers a wide range of Intersan and Prosan restroom units, as well as Multisan restroom trailers.

Unlike plastic portable toilets, these units are:

• built with a rigid aluminum structure,
• much better insulated,
• designed to retain heat efficiently.

They are also equipped with:

• real toilets,
• full heating,
• air conditioning for summer,
• optimized lighting and ventilation.

These solutions provide complete comfort, even during extended use in the middle of winter, and are a preferred option for long-term projects, municipal sites, or events requiring a high standard.
