An overmount kitchen sink refers to a type of kitchen sink that is installed on top of the countertop and supported and secured by the sink's edges. In practical use, it provides users with a direct and stable operating experience, requiring no complex construction under the countertop, making installation and maintenance easier. Its structure typically consists of a single-piece basin with a reinforced panel, giving it a solid feel and preventing wobbling during use. The overmount design creates a clear boundary at the countertop transition, making it easier for users to manage the cleaning area and reduce water splashing, resulting in a more intuitive overall kitchen experience.
| Color: | Gun Grey/Black Titanium |
| Material: | Stainless Steel |

1. Deep-Drawn Forming
The Overmount Kitchen Sink basin is manufactured using deep-drawing technology, allowing the overall depth to consistently reach approximately 180 millimeters, while maintaining a uniform wall thickness with a variation of no more than ±0.3 millimeters after forming. The deep-drawn structure prevents splashing when handling large containers and maintains a stable shape even under repeated impacts.
2. Antibacterial Treatment
The surface features a nano-antibacterial layer, achieving an antibacterial rate of over 99% according to third-party testing, and maintaining high stability, especially in humid environments. The microscopic structure of the coating significantly reduces surface adhesion, decreasing particle retention on the surface by approximately 40%, thus reducing the frequency of cleaning during use.
3. Automatic Welding
The frame and panel are joined using fully automatic laser welding technology, with a weld seam width consistently controlled between 0.8-1 millimeters and a repeatable welding accuracy of ±0.03 millimeters. Compared to manual welding, weld consistency is improved by over 35%, and the heat-affected zone is reduced, effectively minimizing panel deformation after welding.
4. Reinforced Surface Layer
The black titanium or gunmetal gray surface features a dense coating structure, significantly increasing surface hardness. After wear resistance testing, no significant scratches appear after 3000 friction cycles. The high density of the coating reduces the wear rate by approximately 50% when in contact with everyday metal utensils, slowing down the visual aging process.
5. Noise Reduction Structure
A high-density sound-absorbing spray coating material is added to the outer layer of the sink, with a material thickness maintained between 2-3 millimeters. Testing shows that typical water splashing noise can be reduced by 30 to 40 decibels, with a mid-frequency attenuation rate of approximately 45%. For open-plan kitchens, this structure significantly reduces sound transmission interference.
1. Home Kitchens
Overmount kitchen sinks are most commonly used in home kitchens and are suitable for most standard countertop materials. Due to their top-mount design, which eliminates the need for under-counter access, installation requires fewer construction requirements and allows for quick replacement of existing sinks during kitchen renovations.
2. Apartment Delivery
In real estate projects involving finished apartments and rental units, top-mount sinks offer fast installation and high tolerance for errors, facilitating mass construction. Installers only need to place the sink according to the cutout dimensions, reducing the complexity of the process and ensuring timely delivery. The uniform color of the sink surface enhances the overall visual consistency of the kitchen, resulting in a higher degree of standardization and improving the resident experience.
3. Light Commercial Food Service
Suitable for coffee shops, light catering kitchens, and food preparation areas. The top-mount design facilitates quick maintenance, offers a spacious cleaning area, and has a high capacity, allowing for the handling of larger utensils or food trays. Under high-frequency daily use, the sink can meet the demands of continuous operation.
4. Integrated Cabinetry
Ideal for factory-prefabricated integrated cabinet systems. Sinks of specified dimensions can be pre-cut and installed on the production line, making subsequent on-site installation more efficient. Its standardized shape facilitates modular design by cabinet manufacturers, reducing installation obstacles caused by dimensional deviations, improving the overall stability of the cabinet system, and ensuring a consistent appearance.
A: As long as the countertop has sufficient strength and can be drilled, most materials can be installed, including quartz, solid wood, plywood, and some composite panels.
A: If the edges are properly sealed during installation, there will be no water accumulation at the transition between the countertop and the sink. It is recommended to use a special sealant to improve the waterproofing effect.
A: Yes, simply ensure that the drain opening size matches the disposal unit's connector; most models can be directly fitted.
A: The hole position can be customized according to the drainage direction, countertop structure, and internal cabinet layout, making the sink better suited to the actual space configuration.
A: Only daily cleaning with a neutral detergent is required; avoid using strong acid or alkali products to maintain the surface stability and gloss.
