If you have never contracted sanitary disposal before, the model is simpler than it looks: bins you never touch, on a route you never think about, with records you can pull any time.
The route model
Suppliers run geographic routes. A technician covers a set of buildings on a repeating schedule. Your site joins a route, which is why route-dense cities cost less per washroom than remote sites. Everything rides on that visit: bin exchange, dispenser refills, restocking.
What a visit includes
The sealed liner comes out, the unit is sanitized, a fresh liner goes in, and the visit is logged per washroom. A good supplier also checks dispensers in the same room. One trip, no second vendor.
If a supplier quotes bin service and dispenser service as separate visits, ask why. In one washroom, it should be one stop.
How pricing works
Quotes are built from washroom count, service frequency, bin and dispenser counts, product mix, and location. Expect a per-site rate held for the term. And be wary of per-visit surcharges for schedule changes; data-driven adjustment should be free.
Onboarding, step by step
A site walk counts washrooms and mounting surfaces. A placement plan writes out unit type, bin size and frequency per washroom, priced as one quote. Install happens in a single off-peak visit. Then the route runs. Most sites go from first contact to first fill inside three weeks.
Join a route, get a per-washroom plan, and hold the supplier to documented visits. The rest, bins, liners, refills, is their job, not yours.
