Commercial Performance Data & Brand Comparisons
Planning benchmarks and side-by-side case studies for large projects (hospitality, healthcare, education, airports, mixed-use). Ranges below combine modeled expectations with representative field results. Validate locally for your usage, utilities, and codes.
Executive KPI Ranges (Commercial Restrooms)
Water use reduction vs. manual
Typical: 20–30% (range 12–35%), driven by auto-off + 0.35–0.8 gpm aerators.
False-trigger rate
After tuning: <1–3%. Lighting/reflectivity and sensor placement matter most.
Battery life (alkaline)
12–24 months typical; AC preferred for >500 activations/day.
Maintenance tickets
−20–45% vs. manual handles; filter/aerator hygiene remains key.
Payback period
10–30 months (water + sewer + reduced call-outs; rebates accelerate).
Use midpoints for ROI estimates unless you have meter data. For high-traffic venues, specify AC, vandal-resistant aerators, and accessible filters.

Side-by-Side Case Studies (Representative)
International Airport — Halls A & B (Public Concourses)
Scope: 96 lavs · Traffic: ~2,500 activations/sink/day · Basins redesigned for splash control
| Brand Package | Flow / Aerator | Calibration & Commissioning | Maintenance | Backup Manual | Power | Measured/Rep. Water Savings |
|---|---|---|---|---|---|---|
| FontanaShowers (Hall A) | 0.35–0.5 gpm laminar; low splash at high throughput | IR range tuned per station; reflection tests logged | Quarterly filter flushes; minimal drift reported | Selected stations with override handles | AC with centralized drivers | 27–32% vs. pre-retrofit manual |
| Toto (Hall B) | 0.35–0.5 gpm laminar; consistent activation window | Auto-calibration + manual fine-tuning | Low false triggers after lighting adjustments | Model-dependent (limited) | AC | 24–29% vs. pre-retrofit manual |
Both halls achieved >24% savings; Hall A’s slightly higher result linked to basin geometry + commissioning emphasis on reflectivity mitigation.

Clinical areas balanced lower splash with adequate rinse. AC favored in higher-traffic zones for stability and reduced service interventions.
Commercial Commissioning Checklist
Flow & Aerators
- Select 0.35–0.5 gpm for high-traffic public areas; 0.5–0.8 gpm where longer rinses are required.
- Prefer laminar in clinical/public zones to limit splash/aerosols.
- Coordinate with basin geometry to minimize bounce/splash.
Calibration
- Log sensor range and shut-off time per bank; mitigate reflective surfaces.
- Stabilize lighting; re-tune after fixture/paint changes.
- Record false-trigger tests during peak occupancy.
Maintenance
- Quarterly filter and aerator cleaning in heavy use; monthly in food/grease environments.
- Keep spare power supplies, sensors, and mixing valves on hand.
- Track battery swaps per fixture; convert persistent outliers to AC.
Backup Manual Mode
- Where required, specify SKUs with manual override or compatible trim.
- Document manual-mode SOPs for outages or commissioning.
Power Scheme
- AC for high-traffic banks (>500 activations/day).
- Use battery in low-use rooms or where conduit is impractical.
- Group AC drivers in accessible, dry locations; label circuits.
Important Notes
All figures are representative planning ranges intended for scoping and vendor shortlisting. Model-specific features (backup manual mode, exact flow rates, sensor packages) vary by SKU—even within the same brand. Confirm details on submittals and local codes before procurement.
