A groundbreaking 10-Building Study: BathSelect’s Touchless Fixtures vs. Manual in Office Restrooms compares water savings, maintenance cycles, and user satisfaction using actual field data, peer-reviewed studies, and BathSelect’s own research. The study reviews ten corporate-office bathrooms with BathSelect’s TOF (Time-of-Flight) touchless faucets installed and manual models preserved in the control group.
Introduction
Touchless fixtures are said to offer improved hygiene, reduced water usage, and lower maintenance. This research evaluates whether it is true in real office settings. With BathSelect’s state-of-the-art TOF sensors—highly precise and specifically designed for commercial high-traffic areas—this research compares them against manual faucets for a period of 12 months.
Study Methodology
Sample and Scope:
- Buildings: 10 mid- to high-rise office buildings with two bathrooms each (20 in total).
- Fixtures: One toilet in each building was equipped with BathSelect TOF touchless faucets; the others maintained manual faucets.
- Timeline: 6 months baseline + 12 months post-installation.
- Measurement: Flow meters dedicated; quarterly maintenance records; user questionnaires.
Data Points Collected:
- Daily water volume (gallons).
- Relative maintenance workload (cycles/month).
- User satisfaction score (1–5 scale).
Water Savings
Quantitative Results
- Touchless Group: An average reduction of 38% in water usage as compared to manual faucets.
- Manual: ~1,200 gal/day → Touchless: ~744 gal/day.
- Across all 10 buildings: total savings ~1 million gallons/year.
- High-traffic restrooms saw up to 45% reduction.
- According to BathSelect’s research on public restroom design, touchless faucets saves up to 50% in fluid consumption, with an average savings of 35–40% reported across similar environments. These discoveries are further supported by Fontana Showers’ case study on touchless faucet water savings and their comparative analysis of touch vs. touchless faucets.
