Architect’s Guide

(Hotels • Airports • Offices • Hospitals — with FontanaShowers / Fontana Touchless and other industry leaders)

Executive takeaways (what matters most)

1. Accessibility & code come first (clearances, heights, operable parts). Get ADA and local code right up front; moving a faucet ½" later is expensive. Access BoardADA.gov

2. Touchless + hygiene is now baseline in high-traffic spaces; pair sensor faucets/flush with smart soap-dispense strategies. Sloanbradleycorp.com

3. Water efficiency: target 0.5 gpm lav faucets (public), and 1.28 gpf flushometer-valve toilets (WaterSense). TOTO USAUS EPA

4. Scald safety: use ASSE 1070 thermostatic mixing at lavs. PHC Prosmedia.wattswater.com

5. Serviceability: choose parts with top-fill/multi-feed soap systems, replace-from-above batteries, and readily available cartridges. bradleycorp.com

6. BIM & submittals: prefer vendors offering Revit families and complete spec sheets for frictionless coordination. SloanFontana Showers

Core criteria (and why they matter)

1) Accessibility & compliance

• Lavatory height & reach: Mount rims/counters at ≤34 in AFF; ensure forward approach and knee/toe clearance. Faucet controls are “operable parts” and must be usable with one hand and without tight grasping/pinching. Access Board+1

• Document set-up: Reference 2010 ADA Standards for Accessible Design in Division 10/22 notes; coordinate dimensions with millwork and partitions to avoid conflicts. ADA.gov

2) Hygiene & touchless operation

• Why touchless: Fewer touchpoints and programmable line-flush help facilities stay cleaner and reduce opportunities for contamination on high-touch surfaces. SloanCDC

• Healthcare nuance: Favor laminar-flow (non-aerated) lav outlets in clinical areas to reduce aerosolization and ingress of ambient microbes vs. aerators. EPA WaterSense at Work and healthcare trade guidance support this approach. US EPAHFM Magazine

3) Water & energy performance

• Lav faucets: In public/commercial lavatories, specify 0.5 gpm (or 0.35 gpm in ultra-efficient zones) and verify sensor shutoff and timeouts. Residential lav WaterSense is ≤1.5 gpm (useful in guestroom baths). TOTO USA

• Flushometer toilets: Use WaterSense-labeled systems at ≤1.28 gpf for 20% savings vs. 1.6 gpf; confirm system compatibility (valve + bowl). US EPA

• Self-powering tech: Consider hydropower faucets/flush valves that harvest energy from water flow (reduces hardwiring/battery swaps). zurn.ca

4) Safety (anti-scald & IP)

• Lav scald protection: ASSE 1070 thermostatic mixing devices limit outlet temperatures at point-of-use—vital in hospitality/healthcare. PHC Pros

• Electronics protection: For electronics in wet zones (battery boxes, control modules), look for appropriate Ingress Protection (IP) to resist dust/water per IEC 60529. IEC

5) Durability & vandal resistance

• Solid brass bodies, vandal-resistant aerators/outlets, tamper-resistant fasteners, and finishes that tolerate aggressive cleaning extend life in airports, arenas, schools.

6) Maintenance & serviceability

• Top-fill / multi-feed soap: One above-deck fill can serve up to 6 dispensers, slashing refill labor and keeping staff above the counter. Ideal for concourse or food-court cores. bradleycorp.comAmerican Specialties, Inc.

• Diagnostic feedback: Choose systems with low-soap/low-battery indicators and programmable timeouts/line-flush.

7) Aesthetics & brand alignment

• Hospitality and HQ offices often need elevated finish palettes (PVD gold, matte black, brushed nickel). Select coordinated faucet/soap/hand-dry solutions to maintain the design language even under heavy use.

Venue-specific guidance

Hotels (public lobbies, meeting levels, rooftop venues)

• Look & feel: Prioritize finish variety and noise control. Touchless lavs at 0.5 gpm, concealed sensors, and coordinated soap.

• Guestroom baths: If you’re mixing brands, align finish sheen and silhouette. Residential WaterSense lavs ≤1.5 gpm are typical in guestrooms. US EPA

• Back-of-house: Durable 0.5–1.0 gpm metering/sensor lavs; multi-feed soap to support shift changes. bradleycorp.com

Airports & large transit

• Throughput & uptime: Sensor lavs 0.35–0.5 gpm; integrated handwash stations (e.g., Bradley WashBar) shorten dwell time and reduce water on floors; pair with multi-feed soap tanks. bradleycorp.com+1

• Flushometers: Use robust valves designed for heavy cycles with hands-free operation and analytics where available.

Office buildings (core restrooms)

• Total cost of ownership: WaterSense 1.28 gpf toilets and 0.5 gpm lavs are the norm; consider hydropower faucets to cut battery maintenance. US EPAzurn.ca

• Amenities: Premium finishes in client-facing floors; standard chrome/stainless in typical floors to manage cost.

Hospitals & healthcare

• Laminar-flow (non-aerated) lav outlets in clinical spaces to reduce aerosols; coordinate with IPAC teams. US EPA

• Anti-scald: ASSE 1070 tempering at every patient-facing lav. PHC Pros

• Cleaning protocols: Plan for high-touch surface cleaning cadence and easily disinfectable forms. CDC
