Detritus/Services/Hand wash stations
Portable sanitationAll 50 states + DC
Locally sourced. Nationally managed.
10,781 stations placed across all 51 US jurisdictions through 1,548 local providers. A portable hand washing station needs no plumbing or power: it carries its own fresh water, soap and paper towels, and is refilled when the restrooms are serviced. It is also the single most forgotten line on a site services order, because it is billed separately from the restroom on nearly every provider rate card and does not appear unless somebody asks.

There is no single correct ratio, so here is what we have actually placed. Use it to benchmark rather than as a formula.
| Site | Restrooms | Stations | Ratio |
|---|---|---|---|
| Commercial construction, 130 users | 8 standard | 3 | ~1 per 3 |
| Distribution warehouse, 250 people | Three 10-stall trailers | 3 | ~1 per 10 stalls |
| Sports club, year-long | 40 standard | 5 | 1 per 8 |
| Five-week theatre production | 12 standard, 2 ADA | 2 portable sinks | 1 per 7 |
Detritus order records. Health-code-sensitive settings sit at the denser end of this range. A published county contract price for a separate hand-wash station is on the portable toilet rental cost guide.
Separately from code, hand wash capacity is often written into a master service agreement or a site rule, particularly on client-facing and institutional work. That requirement usually sits with the general contractor rather than the sanitation vendor, which is exactly why it gets missed on the order.
On a construction site, 29 CFR 1926.51(f) requires washing facilities where contaminants may be harmful, and it requires lavatories in places of employment, with the water, soap, and drying the paragraph states. The section is read on the OSHA portable toilet requirements page.

Manufacturer figures for a common two-sink model. Tank size varies by provider, so heavy-use sites may need more frequent refills. Every unit type is compared on portable toilet types, and the rules for when stations are required are on hand washing station requirements.
If you are scoping restrooms, scope the stations at the same time and set one service frequency for both. Freshwater replenishment runs on the same schedule, so splitting them across two suppliers creates a gap nobody owns.
Stations come from a local provider that services your address, in all 50 states and DC, usually the same provider as your restrooms. These city pages cover local rules and what we've delivered in each metro. Every other state is on the coverage page.
Between one per three restroom units and one per eight, depending on setting.
Often yes, and by more routes than people expect.
