Reliable, compliant, and professionally serviced portable toilets built for contractors who need zero downtime on their jobsites.
Construction sanitation isn't a comfort question. It's a compliance question, a productivity question, and a workforce retention question. OSHA mandates one toilet per 20 workers for sites under 200 employees, with service requirements that scale by crew size.
Kvaren runs a construction-dedicated service line in St. Charles built around three operational priorities: delivery reliability, service schedule integrity, and billing structures that work with contractor cash flow.
Compliance is the floor, not the ceiling.

"We've used Kvaren for the last four ground-up commercial projects in St. Charles. Service schedule has never slipped. When we expanded the crew mid-project and needed two more units, they had them onsite in three hours. Invoicing is clean and matches the contract every time."
— James Burkhardt, Project Superintendent
"Honest review: had one bad service visit early in our project — tech missed restocking paper. Called Kvaren the same morning, they had a different tech back within four hours to fix it and credited us for the missed service. No argument."
— Tony Marchetti, Site Foreman
A general contractor in St. Charles running a 40-person crew once tried to save money by renting two units instead of three. He calculated $150/month in savings. Over ten months the crew lost roughly 90 hours of productive labor per month due to wait times. That’s close to $50,000 in lost productivity.
