The top mount stainless steel kitchen sink is a countertop stainless steel kitchen sink. The entire bowl and outer edge are integrally formed by stretching. The main body is constructed of 304 stainless steel. The faucet hole and drain are visible on the countertop side. The top edge features a silicone seal and stainless steel clips for direct top-down installation. It comes with a 114mm universal drain assembly and is compatible with both quartz and wood countertops.
The Top Mount Stainless Steel Kitchen Sink is made of 304 stainless steel with a chromium content of approximately 18% and a nickel content of approximately 8%. The plate thickness is approximately 1.2mm thick in 18-gauge, with an optional thicker 1.5mm thicker 16-gauge plate. It offers superior corrosion and pitting resistance to 201 stainless steel and maintains its gloss after 72 hours of neutral salt spray exposure. The entire bowl is stamped and welded without any welds, and can withstand a single point load of at least 40kg, meeting concentrated loads when cleaning cast iron pots and baking pans.
The recommended external dimensions for a Top Mount Stainless Steel Kitchen Sink are 680 x 480 mm, corresponding to an opening of approximately 620 x 440 mm. The effective inner tank measures approximately 610 x 420 x 220 mm, with a capacity of approximately 56 liters. The inner wall features a slight drainage slope of 1.5 to 2 degrees, directing water radially from the bottom to the center. The curved edge of the countertop forms a water barrier, preventing overflow.
The outer wall of the Top Mount Stainless Steel Kitchen Sink is fully covered with a 3mm composite sound-absorbing pad, with a coverage rate of at least 70%, significantly reducing the sound of falling water and metal collisions. The bottom is sprayed with a 0.4mm anti-condensation coating, preventing condensation from forming outside the sink even during prolonged cold water use, significantly reducing the risk of moisture on wooden countertops. An EVA cushioning strip is attached to the contact surface of the sink, allowing nighttime washing without disturbing neighboring rooms.
The interior of the Top Mount Stainless Steel Kitchen Sink features a straight-grain brushed finish with R10 rounded corners, eliminating any accumulation of rags at the corners. With a surface hardness of approximately 3H, it's impervious to visible scratches from a knife or fork. Repeated wet rubbing with a neutral detergent for 500 times yields a color difference of less than one. Common oil stains and coffee marks are quickly removed, maintaining a uniform, fresh appearance.
The flange is approximately 25mm wide, with a reversed folded edge for increased circumferential rigidity. The Top Mount Stainless Steel Kitchen Sink comes with a full-circle silicone seal and eight stainless steel clips, suitable for countertop thicknesses of 20 to 40mm. After slotting, the sink is pressed from below and sealed in one step, preventing moisture from penetrating the countertop. On-site positioning takes less than 30 minutes.
The drain port is an internationally compatible 114mm, compatible with garbage disposals or basket drains. The Top Mount Stainless Steel Kitchen Sink comes standard with 40mm and 50mm pipe adapters for quick connection to both wall and floor drains. The trap seals at least 50mm high for more reliable kitchen odor control, and subsequent maintenance and replacement parts are plug-and-play.
Replacing the old sink without dismantling the cabinets, the holes and grooves are cut into quartz or wood-based panels according to a template. The single-basin, 220mm deep cavity accommodates high-sided woks and baking trays flatly, and the brushed finish is fingerprint-resistant and easy to scrub. On-site confirmation of the countertop thickness and drainage direction is sufficient, and the work can be resumed within the same day, shortening the rental-sale transition period.
The kitchen is cleaned centrally on the day of departure. R10 rounded corners eliminate stubborn hygienic corners, and the seals and clips are clearly inspected. The 114mm standard drain port connects directly to the existing piping, and the anti-condensation coating reduces moisture in the cabinet. The housekeeping team conducts rapid inspections and photographs by room number for archiving, ensuring efficient and stable room status transitions.
Cup cleaning is frequent during weekdays, morning and evening. The rolled edge and nine-inch basin depth prevent water from forming on the countertop. Maintenance for countertop structures requires only top-mounted installation and removal of the drain or faucet, eliminating the need to dismantle the cabinets, minimizing downtime. Cleaning staff can quickly wipe down the sink with a neutral solution during off-hours, ensuring it's ready for use the next day.
Space behind the bar is limited, and the 680 x 480 mm design provides ample storage without obstructing aisles. Milk jugs and pour-overs are rinsed in a tray and placed on a drain rack. A sound-absorbing layer controls the noise of nighttime product rinsing. Final cleaning is completed within ten minutes of closing, ensuring smoother preparations for the next day's opening.
Real estate projects strive for standardized installation and a consistent appearance. The standardized 680 x 480 mm design and template facilitate streamlined construction on-site, ensuring smooth coordination between cabinet and plumbing teams. For future maintenance, top-mounted stainless steel kitchen sinks are replaced with the same specifications. Spare parts are managed by model in the warehouse, minimizing model number confusion and on-site waiting time.
