Buying Guide
What outlet size do I need?
Consider the typical waste flow and the plumbing fittings you already have. Smaller outlets (2″) fit many residential apps, while larger or multiple outlets may be better for busy commercial spaces.
What sump depth matters?
sump depth affects drainage performance and installation height. Deeper sumps (6″) are common in commercial sinks, while shallower options suit compact areas.
Material and build quality
Polymer sinks and domed strainers offer corrosion resistance and easier maintenance in busy environments. Durability is crucial in both commercial kitchens and high-usage home spaces.
USB and power considerations
For spaces needing charging, look at floor boxes with USB ports and weather-resistant housings. Tamper-resistance adds safety in public areas.
Installation and maintenance
Choose products designed for straightforward installation with clear service paths. Recessed or floor-box designs can reduce trip hazards and create a clean appearance.
Space and accessibility
Assess the floor area where the unit will sit. Low-profile designs reduce foot obstruction, while larger units may be better for high-traffic settings.
Best practice checklist
- Confirm outlet size and sump depth match your plumbing layout.
- Check compatibility of strainers and gratings with your chosen model.
- Evaluate the availability of local support and replacement parts.
- Ensure the design aligns with safety requirements in your environment.
