American Standard Trimbrook 0.85–1.0 GPF Urinal
This urinal uses a siphon jet flush action with a low 1.0 gpf/3.8 Lpf consumption. It is best for medium- to high-traffic restrooms where reliable draw and minimized water use are priorities. The flushing rim helps ensure efficient waste removal with standard maintenance expectations. Choose this if you want a proven American Standard design with strong water savings.
Best for: Commercial restrooms or public facilities seeking proven efficiency and a compact footprint.
Caution: Availability of service parts should be confirmed for older plumbing configurations.
Maybrook Universal Washout Urinal (1.0 GPF)
This model offers a wide flush range from 0.125 to 1.0 gpf, with a powerful washdown action and a flushing rim. It’s best for projects that require flexible water use and the ability to optimize flush volume based on occupancy. The HEU compatibility makes it suitable where code-compliant efficiency matters.
Best for: Restrooms that require adjustable flush performance or upgrading from older, higher-flow units.
Caution: Complex installations may require compatible supply lines and careful measuring of mounting hardware.
Shawoo Wall-Mounted Urinal With Lid
This wall-mounted option includes an odor-dispersing lid, a flushing interface, and a long drain hose. It’s best for compact spaces where odor control and space savings are priorities. The dual mounting options support varied wall conditions. It can be a practical alternative when a full-sized commercial unit is not feasible.
Best for: Small restrooms, outdoor setups, or areas needing odor control with minimal footprint.
Caution: May require additional parts for flush valve compatibility and wall mounting robustness.
OMISTAR Wall-Mounted Urinal With Cover
Includes a hygienic lid and complete flush valve kit. It’s best for residents or small facilities that prioritize odor control and easy installation with optional no-drill mounting. The kit’s flexible drain and dual-caliber connections help accommodate different plumbing layouts.
Best for: Apartments, garages, or RV-friendly installations where space and odor concerns are key.
Caution: Some setups may require custom adapters for optimal performance with existing pipes.
Sloan Regal 186 Exposed 1.0 GPF Flushometer
The 1.0 GPF Regal 186 flushometer emphasizes water conservation with a non-hold-open handle and no external volume adjustment. A vacuum breaker flush connection protects against backflow for hygienic operation. This option suits mid- to large-scale commercial projects where consistent flush performance matters.
Best for: High-traffic commercial restrooms needing reliable, code-friendly flushing.
Caution: Some installations may require specific supply lines and mounting hardware (not included).
Sloan Regal 186 Exposed 0.5 GPF
This lower-flow version supports water efficiency without sacrificing washdown effectiveness. The 0.5 GPF rating targets facilities aiming to cut water use while maintaining hygiene. Like its 1.0 GPF sibling, it relies on a vacuum breaker flush connection.
Best for: Renovations or new builds where water savings are a priority and space is limited.
Caution: Lower flow may require slightly longer flush cycles in very soiled restrooms.
Sloan Regal 111 1.6 GPF
The Regal 111 uses 1.6 GPF with Para-Flo technology for efficient flush performance. It is designed for heavy-use environments where robust cleaning is necessary. Vacuum breaker flush connection enables hygienic operation and backflow prevention.
Best for: Very high-traffic facilities or spaces requiring strong, reliable flushes.
Caution: Higher water use compared to low-flow models; assess water availability and costs.
Buying Guide
- Water efficiency vs. flush power: Consider gpf ratings (0.125–1.6 gpf range). For compact spaces or cost-conscious projects, choose models with lower gpf. For high-traffic areas, reliable higher-flow units can reduce re-flushing needs.
- Flush mechanism: Siphon jet, washdown, and diaphragm-style flushometers offer different performance. Siphon jet provides strong waste removal with lower water use; washdown delivers a more straightforward flush for some layouts.
- Valve type and maintenance: Exposed flushometers are easy to service but may require space for maintenance. Hidden or wall-mounted options save space but may need more careful installation planning.
- Backflow prevention: Vacuum breaker connections protect the water supply. Ensure your installation includes or accommodates this feature where required by code.
- Installation space: Measure mounting height, wall strength, and available space. Some units have compact footprints and removable lids for odor control, while others require more room for valves and piping.
- Materials and durability: Look for vitreous china or durable plastics designed for commercial use. Finish and corrosion resistance matter in humid or damp environments.
- Maintenance access: Consider ease of access for cleaning, deodorizing, and parts replacement. Sealed lids and odor pads can help, but ensure maintenance teams can reach critical components.
Frequently Asked Questions
- What does gpf mean? Gallons per flush; a lower number indicates less water used per flush.
- Do flush valves require professional installation? Many do, especially in commercial settings, to meet code and ensure proper venting and water supply connections.
- What is a vacuum breaker? A backflow-prevention device that protects drinking water from contamination during flushing.
- Are all these units compatible with wall-mounted drains? Most are designed for standard drain configurations, but verify measurements and piping specs for your space.
- Which model is best for high-traffic areas? Models with higher reliability and robust flush performance (like 1.0–1.6 GPF variants) are commonly chosen for busy facilities.
- Can I mix lid-equipped and lidless urinals in the same restroom? Yes, but consider odor control, cleaning routines, and consistency in maintenance practices.
