Commercial Wall-Mounted Knee-Operated Hand Wash Sink

SENFON manufactures commercial wall-mounted knee-operated hand wash sinks for hospitals, clinics, laboratories, food processing rooms, restaurant kitchens, hotel kitchens, chain stores, shopping malls, canteens and B2B hygiene projects. This stainless steel hand wash sink is designed for hands-free operation: users press the front knee-operated push panel with the knee to start water flow, helping reduce direct hand contact during washing.

This product is not a regular wall-mounted sink. It is a dedicated knee-operated hands-free hand wash station with a one-piece deep-drawn sink bowl, wall-mounted stainless steel body, faucet, pure copper delay shut-off valve, hot/cold water mixing parts, stainless steel water hoses and drain set. SENFON developed a custom mold for the knee-operated switch structure, making the product more suitable for commercial hygiene environments and B2B project supply.

This product belongs to SENFON’s Commercial Sinks & Specialty Equipment series. It is especially suitable for buyers who need compact wall-mounted hygiene sinks for commercial kitchens, food factories, medical-related facilities, public handwashing areas and project installations.

Commercial Wall-Mounted Knee-Operated Hand Wash Sink

The Commercial Wall-Mounted Knee-Operated Hand Wash Sink is designed for hygiene-focused handwashing areas where users should avoid touching the faucet or valve directly with their hands. Instead of turning a faucet handle by hand, the user lifts the knee slightly and presses the front semi-round knee-operated panel. The water starts flowing through the faucet, and the pure copper delay shut-off valve allows the water to continue for a short period after release before closing automatically.

This operation method makes the sink suitable for commercial hygiene stations, food preparation areas, medical clinics, laboratories, restaurants, hotels, chain stores and other environments where hands-free washing is preferred.

Key Features

• Knee-operated hands-free design: users press the front knee panel to start water flow without touching the faucet by hand.
• Pure copper delay shut-off valve: water continues briefly after release, then shuts off automatically depending on valve configuration.
• SENFON custom knee switch mold: the knee-operated switch structure uses a custom-developed mold for stable operation and clean appearance.
• One-piece deep-drawn sink bowl: smooth bowl surface with clean formed structure, suitable for handwashing use.
• Wall-mounted compact body: saves floor space and is suitable for commercial hygiene stations and limited-space installation areas.
• Default accessory set included: faucet, knee switch set, pure copper delay valve, copper hot/cold water mixer, stainless steel water hoses and drain set.
• SUS304 recommended: SUS304 stainless steel is recommended for hygiene and humid washing environments; SUS201 can also be discussed for selected markets.
• Regular sizes available: 400×400 mm, 435×410 mm, 450×450 mm and 500×450 mm.
• Custom dimensions supported: size, material, body structure and accessory configuration can be customized for project requirements.

Hands-Free Knee Operation for Better Hygiene

In commercial handwashing areas, reducing hand contact with faucet handles or valves is important. This knee-operated hand wash sink allows users to activate water flow by pressing the front knee panel instead of touching the faucet by hand.

This is useful when users need to wash hands before food preparation, after handling ingredients, before entering a clean working area, or after using cleaning tools. For hospitals, laboratories, restaurant kitchens, food processing rooms and chain store back kitchens, hands-free operation can help support cleaner handwashing workflows.

This product should not be confused with a normal wall-mounted hand wash sink. The core feature is the front knee-operated push panel combined with the pure copper delay shut-off valve.

Pure Copper Delay Shut-Off Valve

The sink is equipped with a pure copper delay shut-off valve. After the user releases the knee-operated panel, the water continues to flow for a short time and then closes automatically according to the valve configuration.

This delay function helps users complete handwashing without continuously pressing the knee panel. It also helps reduce unnecessary water use compared with faucets that may be left open manually. The exact delay time can vary depending on valve configuration, so SENFON recommends confirming the final valve requirement before order confirmation.

Default Included Accessories

This product is supplied as a complete knee-operated hand wash sink set. The default accessory configuration includes:

• One faucet
• One knee-operated switch set
• One pure copper delay shut-off valve
• One copper hot/cold water mixer or distributor
• Three stainless steel water hoses
• One drain set

The three stainless steel water hoses are used for connecting the hot and cold water mixer and the faucet. Buyers can confirm water inlet direction, plumbing requirement and accessory configuration according to local installation conditions.

One-Piece Deep-Drawn Sink Bowl

The sink bowl is made with a one-piece deep-drawn structure. Compared with a welded bowl, the deep-drawn bowl provides a smooth formed surface and clean inner bowl appearance, which is suitable for commercial handwashing stations.

This structure helps make the product easy to clean and visually neat. For B2B buyers, the deep-drawn bowl also supports consistent product appearance for repeated orders and project supply.

Material and Thickness

This wall-mounted knee-operated hand wash sink can be produced with SUS201 or SUS304 stainless steel. For hygiene handwashing environments, SUS304 stainless steel is recommended because it is more suitable for humid commercial washing areas and long-term use.

The regular thickness range is approximately 0.9 mm to 1.2 mm. The final material and thickness can be selected according to destination market, project budget, installation environment and buyer requirements.

Regular Sizes and Custom Dimensions

SENFON provides several regular sizes for this wall-mounted knee-operated hand wash sink. These sizes are suitable for many commercial hygiene station and project installation requirements.

Wall-Mounted Installation

This product is designed for wall-mounted installation. Before installation, buyers should confirm wall load-bearing capacity, water inlet position, drainage position and site conditions. Different projects may require different installation methods, so final installation should be confirmed by the buyer or local installer according to the actual site.

Because this sink is wall-mounted and includes knee-operated components, the installation height and operating position should be planned carefully to make the knee panel comfortable to use.

Application Scenarios

This wall-mounted knee-operated hand wash sink is suitable for commercial and project environments where hygienic handwashing is important:

• Hospitals and medical clinics
• Laboratories and testing rooms
• Food processing rooms
• Restaurant kitchens and hotel kitchens
• Chain store back kitchens
• Shopping mall food service areas
• School and hospital canteens
• Commercial hygiene handwashing stations
• Catering facilities and central kitchens
• High-end commercial kitchen projects

For local sales, buyers can position this product as a knee-operated hand wash sink, hands-free stainless steel sink, wall-mounted hygiene sink, commercial hand wash station or medical-style hand washing sink.

How This Page Differs from Other Wall-Mounted Sinks

SENFON can manufacture many types of wall-mounted stainless steel sinks and specialty sinks, but this page focuses only on the knee-operated hand wash sink. This distinction is important for B2B buyers and SEO structure.

Product Type	Main Function	Page Focus
Knee-Operated Hand Wash Sink	Hands-free handwashing with knee push operation	Hygiene stations, hospitals, food processing and commercial handwashing
Regular Wall-Mounted Sink	General washing use	Normal handwashing or small washing station
Wall-Mounted Utility or Specialty Sink	Special cleaning, processing or project use	Different structure and application, handled in separate product pages

This helps buyers choose the correct product. If the project requires a hands-free hygiene sink, the knee-operated model is more suitable. If the buyer needs another wall-mounted washing or processing sink, SENFON can provide separate OEM/ODM solutions.
