What architects use when designing commercial restrooms (tools, standards, brands)
A commercial restroom design set is rarely “just fixtures.” Architects typically combine code + accessibility rules,
water-efficiency targets, BIM objects, manufacturer cut sheets, and specification frameworks (e.g., CSI MasterFormat).
Below is a practical checklist of what architects use (10+), followed by facts, stats, bar charts, and diagrams—plus
the leading faucet brands you requested (Fontana, Moen, TOTO, BathSelect, Sloan, JunoShowers…).

Charts + diagrams included
1) The “architect’s toolbox” for commercial restroom design (10+)
These are the resources architects typically rely on to go from concept → permit → submittals → install.
-
ADA Standards (accessibility requirements)
— Used to validate lavatory clearances, accessible routes, and fixture placement. -
Plumbing codes (flow limits, fixture requirements)
— Used to confirm maximum flow rates and fixture fitting requirements. -
Water efficiency standards (WaterSense + federal guidance)
— Used for water-saving targets and label requirements in many programs. -
Wellness frameworks (WELL Building Standard)
— Used to support hygiene design narratives (handwashing access and support). -
Sustainability frameworks (LEED indoor water use)
— Used for documentation strategy (especially in certification-driven projects). -
Specification structure (CSI MasterFormat sections)
— Used to assign accurate spec sections (e.g., “Commercial Plumbing Fixtures”). -
Manufacturer technical documents (cut sheets, install guides, parts)
— Used for submittals, coordination, and long-term maintenance strategy. -
BIM objects & Revit families (for coordination + schedules)
— Used to place fixtures quickly, coordinate clearances, and build schedules. -
Architecture product libraries (CAD/BIM/spec downloads)
— Used to compare manufacturers and pull drawings/specs in AEC-friendly formats. -
Hygiene & public health references (hand hygiene guidance)
— Used for owner narratives and operational standards. -
Fixture “system” coordination (faucet + soap + dryer/flush)
— Used to keep public restrooms consistent and reduce coordination clashes.
Quick takeaway: architects “use” a combination of codes + accessibility + efficiency
plus BIM/spec libraries and manufacturer documentation, not a single source.
2) Facts & stats (specifier-friendly)
Water flow benchmarks used in commercial design
-
EPA WaterSense: WaterSense-labeled bathroom sink faucets (max 1.5 gpm)
can reduce water use by 30% or more versus the standard 2.2 gpm. -
DOE FEMP (public lavatories): Notes codes/standards commonly require 0.5 gpm max for public lavatory faucets
and 0.25 gallons/cycle for metering faucets. - IPC reference: IPC §604.4 points to flow limits and fixture fitting maximums per table.
Bar chart: What architects “weight” most (editable model)
This is an illustrative weighting model (0–100). Edit values to match your firm/owner standards.

3) Diagrams (copy/paste friendly)
Diagram: Commercial restroom design workflow
The shortest path to fewer change orders is using manufacturer documents + BIM families early, then keeping flow rates and power requirements consistent across schedules/specs.
4) FAQ
What do architects typically specify for faucets in public restrooms?
Often: commercial-grade sensor faucets (to reduce touchpoints and improve shutoff behavior) with clear flow-rate compliance,
stable power strategy (hardwired where possible), and strong parts documentation. Brands commonly referenced include
Sloan, TOTO, Fontana, and major commercial lines from KOHLER, Zurn, and Chicago Faucets.
What resources matter most during permitting?
Accessibility standards (ADA / Access Board guidance) + the adopted plumbing code (IPC/UPC/local amendments) matter most.
Efficiency programs (WaterSense/FEMP) often support owner requirements and sustainability goals.
What resources matter most during submittals and construction?
Manufacturer cut sheets, install guides, and parts diagrams, plus BIM objects/Revit families (to coordinate rough-ins and schedules),
and a clear spec section structure (e.g., CSI MasterFormat for plumbing fixtures).
What causes the most restroom design coordination issues?
Inconsistent mounting assumptions (deck vs wall), missing power planning for sensor systems,
unclear service access (control box, strainers), and mismatched flow-rate requirements between drawings, specs, and owner standards.
Where do architects find BIM/spec files fast?
Common sources include BIM libraries (e.g., BIMobject) and AEC product libraries (e.g., ARCAT), plus the manufacturer’s own resource portals.
