Plan hygienic restroom setups for busy crews today. Compare units, wash stations, supplies, and servicing rates. See clear targets for safer, compliant worksites now.
| Scenario | Workers | Toilets | Handwash | Service / Week | Travel (min) | Score | Status |
|---|---|---|---|---|---|---|---|
| Small crew, close access | 12 | 1 | 1 | 1 | 3 | 90 | Compliant |
| Mid crew, low servicing | 60 | 2 | 2 | 1 | 6 | 63 | Needs improvement |
| Large crew, under-supplied | 180 | 3 | 4 | 1 | 8 | 48 | Non-compliant |
1) Minimum toilets target
If workers ≤ 20: Required Toilets = 1
If 21–199: Required Toilets = ceil(Workers / 40)
If ≥ 200: Required Toilets = ceil(Workers / 50)
2) Handwash target
Required Handwash = ceil(Workers / 20)
3) Weekly waste estimate
Weekly Uses = Workers × UsesPerDay × 7
Weekly Waste (L) = Weekly Uses × LitersPerUse
4) Effective weekly capacity
Capacity per service (L) = Toilets × TankCapacity × FillLimit
Effective Weekly Capacity (L) = Capacity per service × ServicesPerWeek
Sanitary facilities reduce illness risk, protect productivity, and support worker dignity. On active sites, higher heat, dust, and overtime can raise restroom demand. A simple, repeatable scoring method helps supervisors spot gaps early and plan service before conditions become unacceptable. It also supports infection-control programs during seasonal outbreaks and flu waves.
This calculator combines people, units, handwashing access, and servicing rhythm. Crew size influences queueing and usage load, while the number of units spreads demand. Handwash stations, soap, water, towels, and sanitizer reduce contamination transfer, especially around eating areas and shared tools.
Odor, overflow risk, and cleanliness complaints often trace back to servicing that lags behind actual use. The model estimates weekly tank load from daily uses and average liters per use, then compares it with capacity and service visits. When projected load exceeds capacity, the score drops sharply.
Handwashing is not only a “nice to have”; it is the fastest way to lower cross‑contamination. The calculator checks station-to-unit coverage and penalizes missing soap/water/paper towels. If you rely on sanitizer, treat it as a supplement and verify dispensers are filled and accessible.
Long travel time can lead to avoidance, unsanitary behavior, or reduced hydration. Many sites aim for a short, practical walk from work fronts. Use the travel-time input to reflect your layout, barriers, and elevation changes, then reposition units or add satellite units where needed.
The score is a weighted blend of: unit ratio adequacy, handwash coverage, servicing sufficiency, travel time, and supply/condition checks. Each factor contributes a capped sub-score, then totals to a 0–100 result. This creates a consistent benchmark for crews, projects, and subcontractors.
Document servicing dates, vendor tickets, restock checks, and corrective actions. The CSV/PDF exports provide a quick snapshot of inputs and calculated risk, useful for toolbox talks and safety walks. Pair the export with photos and a short note of any temporary constraints.
Start with the fastest fixes: restock supplies, clean touch points, and add signage. Next, increase service frequency during peak phases, adjust unit count as headcount changes, and add handwash stations near break areas. Recalculate weekly to confirm improvements are holding.
It is a practical indicator of hygiene readiness based on staffing, unit availability, handwashing support, servicing sufficiency, and access. It helps prioritize actions; it does not replace local regulations or a qualified safety assessment.
Service frequency depends on headcount, shifts, weather, and usage. Use your vendor’s plan as a baseline, then increase visits when the model shows capacity risk or when complaints, odor, or visible soil indicates conditions are degrading.
If units are far away, workers may delay use, reduce hydration, or skip handwashing. Shorter access encourages proper use and makes it easier to keep units clean because they are visited more regularly during routine checks.
Sanitizer helps, but soap and water are more effective for many jobsite soils and after restroom use. Where plumbing is unavailable, provide stocked handwash stations and keep sanitizer as an additional option at entrances and break areas.
Use an average capacity that matches most units, or run separate checks for each type. If you mix standard and high-capacity units, consider calculating with the smaller capacity to stay conservative.
Save exports with the date, project, and area. Attach vendor service tickets and your restock checklist. During audits, the export shows your assumptions and resulting actions, making it easier to explain why you adjusted units or servicing.
Address immediate hygiene risks first: supplies, handwashing coverage, and unit condition. Next, increase service frequency or add units to reduce loading. Finally, improve placement to cut travel time and set a weekly review cadence.
Clean restrooms protect workers, boost morale, and productivity daily.
