When winter rolls around, it is important that your workers feel as comfortable as possible on the job site. Portable restrooms can be kept warm all through the cold months with the use of electric heaters in each of your restrooms. These heaters can keep your job and your workers comfortable this holiday season. Along with providing comfort to your site, heaters are also required by Minnesota State Law Revisor 5207.0800 which states “Where privies are not placed inside of heated building, provisions shall be made for heating privies to a minimum of heat that can be emitted from the installation of a 1,300 watt heater or other type equivalent heater.” 

To be sure that your job site is working as best as possible, call us and request an electric heater to be placed in your portable restroom this winter season.
