FontanaShowers WELL Water Quality Fixture Solutions | Healthy Building Standards
Water quality has become an increasingly important coordination issue for architects, plumbing engineers, sustainability consultants, commissioning teams, and facility managers. In high-performance buildings, the design question extends well beyond whether potable water reaches a fixture. AEC teams must consider water quality, material compatibility, stagnation risk, temperature control, hydraulic performance, accessibility, commissioning, and long-term maintainability as interconnected parts of the building water system.

The WELL Building Standard provides a useful framework for this approach. WELL's Water concept addresses fundamental water quality, inorganic and organic contaminants, periodic testing, treatment, and ongoing water-quality management. Its Fundamental Water Quality feature specifically uses performance testing to evaluate indicators such as turbidity and microbial contamination.
Within that broader framework, FontanaShowers commercial bathroom fixtures can serve as coordinated point-of-use components—not as stand-alone water-treatment devices, but as fixtures selected and documented to support healthy-building plumbing strategies.
The Fixture as the Final Interface in a Healthy Building Water System
Water reaching a lavatory or shower has already passed through a complex chain:

Source → treatment → building entry → distribution piping → temperature management → branch piping → fixture → occupant
A water-quality strategy can therefore fail at several stages even when incoming municipal water meets applicable requirements.
WELL recognizes this system-level relationship by addressing both water testing and treatment. Its Water Treatment feature identifies filtration, microbial control, drinking-water access, and water-quality maintenance as building-level considerations, with MEP involvement specifically identified for several design verification pathways.
For architects and engineers, this means a commercial plumbing fixture specification should evaluate more than finish, shape, and mounting type. Important technical questions include:
- What materials are in contact with potable water?
- What is the specified flow rate and operating pressure?
- How is hot and cold water mixed?
- Is the fixture compatible with the project's temperature-control strategy?
- Can filters, solenoids, cartridges, and valves be serviced?
- How is the sensor commissioned?
- Does basin geometry support the intended sensing and discharge zone?
- Are BIM geometry and MEP connection points coordinated before construction?
FontanaShowers provides a dedicated architect and specifier technical resource library with BIM files, dimensional information, installation resources, and specification documentation intended to support this coordination.
Water-Contact Materials and Potable-Water Specifications
Fixture materials are particularly important where the outlet supplies water for human contact.

NSF/ANSI/CAN 61 establishes health-effects requirements related to contaminants or impurities that products and materials may impart to drinking water. NSF/ANSI/CAN 372 addresses lead content and establishes a standardized methodology for determining compliance, including a maximum weighted lead content of 0.25% for most covered components. Faucets are among the product categories addressed.
For AEC specifications, these requirements should be verified for the exact scheduled product, rather than inferred from an entire collection or manufacturer.
That distinction is central to responsible healthy-building specifications:
Specify the model. Verify its documentation. Coordinate its system conditions. Preserve the records in the submittal package.
FontanaShowers' commercial touchless sensor faucet resources and BIM documentation provide a starting point for model-level review by architects, engineers, and plumbing specifiers.
Touchless Fixtures: Hygiene and Controlled Water Delivery
Touchless fixtures have a useful role in healthy commercial restroom design, but their function should be described accurately.

A sensor faucet does not purify incoming water. Its primary contribution is controlled point-of-use operation. Automatic activation and shutoff can reduce unnecessary runtime while eliminating the requirement for users to manually operate conventional handles.
This can be especially relevant in:
- healthcare facilities,
- airports and transportation terminals,
- corporate workplaces,
- universities,
- hospitality properties,
- government facilities,
- stadiums and assembly occupancies.
FontanaShowers' architect-specified touchless faucet resources place sensor performance within a wider specification framework that includes hydraulic performance, accessibility, durability, maintainability, and building-system integration.
For high-traffic projects, engineers should also coordinate sensor range, false-trigger resistance, power architecture, automatic shutoff, access to solenoids and strainers, and basin geometry.
Water Efficiency Without Compromising System Design
Healthy-building design and water conservation frequently intersect.

EPA guidance notes that public lavatory faucets in non-private toilet facilities typically use 0.5 gallons per minute or less to satisfy efficiency objectives and applicable plumbing-code requirements.
Flow rate, however, should never be specified independently of the rest of the system.
AEC teams should evaluate:
Q = fixture flow rate
P = available dynamic pressure
T = hot-water delivery time
D = distribution distance
U = anticipated fixture-use frequency
A very low-flow fixture connected to a poorly coordinated hot-water distribution system can increase the time required for temperature stabilization. The engineer must therefore balance efficiency with supply pressure, pipe sizing, recirculation strategy, outlet temperature, occupant use, and applicable plumbing regulations.
FontanaShowers identifies low-flow configurations among its commercial touchless fixture strategies, with exact flow, power, certification, pressure, and sensing values treated as model-specific specification data.
Thermostatic Control, Temperature and Legionella Risk Management
Water temperature is also relevant to both occupant protection and building-water management.

Touchless fixtures with compatible thermostatic or mixing strategies can provide controlled point-of-use temperatures while the plumbing engineer manages the larger domestic hot-water system.
FontanaShowers provides touchless thermostatic commercial faucet configurations that can be evaluated by project teams where automatic operation and temperature management are required.
This coordination should also be considered alongside building water-management planning.
ANSI/ASHRAE Standard 188 establishes minimum Legionellosis risk-management requirements covering the design, construction, commissioning, operation, maintenance, repair, replacement, and expansion of applicable building water systems.
Fixtures themselves do not eliminate Legionella risk. Instead, the specification should support the project's broader strategy by considering temperature, flushing, stagnation, piping configuration, maintenance accessibility, and commissioning.

The design team first establishes incoming water-quality requirements and the project's treatment and monitoring approach. Plumbing engineers then coordinate domestic water pressure, hot-water recirculation, branch piping, mixing, and required fixture flow.
At each public lavatory, an automatic sensor faucet is positioned according to basin geometry. The spout discharge point is coordinated with the basin landing zone, while the sensor envelope is checked for reliable hand detection without unnecessary activation.
Controls and solenoids remain accessible below the counter or through a designated service zone. The project BIM model records fixture location, supply connections, electrical requirements, mounting geometry, and maintenance clearance.
Accessibility is coordinated simultaneously. Under the 2010 ADA Standards, accessible lavatories must comply with Section 606, while faucet controls are required to comply with the operable-parts criteria of Section 309.
During commissioning, the team verifies:
sensor activation → water flow → temperature → shutoff → splash control → service access
The facility team then receives product schedules, maintenance requirements, replacement-part information, commissioning records, and the building water-management plan.
This is an example of how fixture specification becomes part of a broader healthy-building operational strategy, rather than simply a product-selection exercise.
BIM, Division 22 and Specification Authority
For architects and engineering teams, documentation is as important as the fixture itself.

FontanaShowers provides automatic sensor faucet BIM and Revit resources for digital coordination and an AEC specification resource structured around CSI MasterFormat Division 22 plumbing requirements, including guidance for electronic lavatory faucets, flow control, sensing, power, installation, testing, commissioning, and closeout.
This allows the fixture specification to move through a professional project workflow:
Design Intent → BIM Coordination → Division 22 Specification → Submittal → Installation → Commissioning → Facility Operations
Supporting WELL Water Quality Through Better Fixture Coordination
A fixture should not be represented as independently making a project WELL certified.
WELL is fundamentally concerned with measurable building and occupant outcomes. Its Water features address actual water quality, testing, treatment, contaminant control, and ongoing management—not simply the presence of a particular faucet.
The stronger AEC approach is therefore to specify WELL-aligned commercial bathroom fixture solutions that fit within an engineered water-quality strategy.
For FontanaShowers projects, that means combining carefully selected commercial touchless fixtures with model-specific certification review, controlled water delivery, thermostatic coordination where appropriate, accessibility planning, BIM integration, commissioning, and maintainable plumbing design.
When these elements are addressed together, the fixture becomes more than an architectural finish.
It becomes the final engineered interface between the building water system and the occupant—and an important component of a healthier, more measurable, and more resilient built environment.
