Four decisions define a dispenser program: vend type, capacity, mounting, and who keeps it stocked. Get those right and the unit disappears into the washroom. Which is the goal.
Free-vend vs coin
Free-vend is now the default: the federal requirement asks for products at no cost, and coin mechanisms fail more often than any other part. If you have sound coin units, a conversion kit usually beats replacement.
Coin-operated units do not satisfy a free-of-charge standard. That's the compliance detail most retrofits miss.
Sizing by traffic
A dual-column unit (~40 units) covers a standard office washroom for weeks. High-traffic washrooms, schools, arenas, event venues, need high-capacity units (~80) or they run dry between visits. Small single-stall rooms take a compact column.
Mounting and accessibility
The push slide must land inside accessible reach range, clear of the stall door swing, on a wall that takes a four-point fixing. Tile, drywall and block all work with the right anchors, set the height at install, not after the first complaint.
Who keeps it stocked
An empty dispenser is worse than no dispenser. It advertises the gap. Put refills on the same route as your bin service, with fill levels logged per visit, and the run-out problem disappears into the schedule.
Free-vend, sized to traffic, mounted accessibly, stocked on a documented route. Four decisions, then the unit takes care of itself.
