Hands-Free Hand Sinks
A hands-free hand sink turns the water on and off without the user touching a faucet handle, so freshly washed hands are not recontaminated by a dirty valve. The three common mechanisms are a knee valve (a paddle below the bowl pushed with the knee — the most common and lowest-maintenance in kitchens), a foot pedal (floor-mounted, good for high-traffic stations), and a touchless sensor faucet (premium and public areas, but it needs power or batteries). Hands-free operation is frequently required or preferred at food-prep and cook-line handwashing stations under local health codes, and it measurably cuts cross-contamination. Choose knee or foot activation for durability in a back-of-house kitchen, and sensor faucets where appearance and touchless convenience matter; confirm what your jurisdiction requires before buying.
Hands-free hand sinks run the water with a knee valve, foot pedal, or touchless sensor so clean hands never touch a handle — often required or preferred for food-code handwashing. Compare knee, foot, and sensor models below.

About this data
Last verified: August 2026. Specs are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn't published we leave it blank rather than guess.
Methodology: every hand-sink model is compared on the same set of specifications, and dimensions are checked (for sinks, overall width must exceed the combined bowl widths) — figures that fail validation are corrected from the manufacturer model number or omitted. “Street price” is the lowest legitimate published price we've found and can change.
Sourcing: product specs come from the manufacturer; regulatory statements link to the source (e.g. the FDA Food Code and NSF). Code requirements vary by jurisdiction — confirm with the authority reviewing your plans.
