Deep Single Bowl Handmade Topmount Kitchen Sink with Faucet Hole

Deep Single Bowl Capacity

The HA06456’s basin measures 533×400mm with a 228mm depth, providing sufficient volume for washing large stock pots, baking sheets, and roasting pans in a single uninterrupted basin. Unlike double-bowl configurations where the divider limits the size of items that can be submerged, the single-bowl design allows the full basin footprint for oversized cookware.

For contractors specifying kitchens in multi-unit residential developments, the single-bowl format reduces installation complexity (one cutout, one drain assembly) while providing the deep capacity that residents expect for everyday cookware cleaning. The 228mm depth also contains splash within the basin, protecting surrounding laminate or tile countertops from water damage, which is a warranty concern in rental and multi-family properties.

Topmount Drop-In Installation

Rim and Deck Mounting

The topmount configuration features a perimeter rim that rests on the countertop surface, with the basin suspended below. The sink is secured from underneath with mounting clips that compress against the countertop bottom face. A silicone sealant bead between the rim and countertop prevents water infiltration at the rim-to-deck interface.

This installation method is compatible with countertop materials that cannot support undermount mounting, including post-form laminate (the most common countertop material in North American multi-family construction), butcher block wood, and ceramic tile. For contractors working with these materials, the topmount format eliminates the need for solid surface countertops, reducing project material costs.

Countertop Compatibility

The sink rim requires a flat mounting surface of at least 20mm width around the cutout perimeter. The cutout dimensions are provided in the technical drawing package, which includes template layouts for accurate on-site cutting. For project procurement teams ordering sinks for multiple units, Xinhe provides cutout templates in digital and physical format to ensure consistency across installations.

Pre-Drilled Faucet Hole

Standard Faucet Fit

The faucet hole is pre-drilled to accommodate standard single-handle kitchen faucets with a 35mm (1-3/8 inch) mounting diameter. The hole position is located on the sink deck, set back from the back wall to provide clearance for faucet base rotation and spray head extension. For buyers sourcing faucets separately, the standard hole diameter ensures compatibility with faucets from major manufacturers including Moen, Delta, Kohler, and Grohe.

Optional Hole Configurations

For projects requiring non-standard faucet configurations, Xinhe can produce the sink deck with additional holes for accessories such as soap dispensers, filtered water taps, or air gaps. The hole count and positions are specified at the time of order, with custom deck layouts produced within the standard manufacturing lead time. This customization is available for OEM clients developing product lines with specific accessory packages.

Brushed Surface Finish

Scratch and Stain Resistance

The brushed satin finish is produced by mechanically abrading the stainless steel surface with abrasive belts in a uniform direction, creating fine parallel lines that diffuse light reflection. This finish masks minor scratches from daily use, as new scratches blend with the existing brushed pattern rather than appearing as distinct marks on a polished surface.

The surface resists oil adhesion due to the non-porous nature of stainless steel, and the material does not support bacterial colonization when cleaned with standard kitchen sanitizers. For food preparation environments, this means the basin surface can be sanitized by wiping with a cloth and food-safe sanitizer, without requiring specialized cleaning products or sealants.

Maintenance and Cleaning

Routine cleaning uses a non-abrasive cloth with warm water and mild detergent. For stubborn residues, a paste of baking soda and water applied with a soft cloth removes stains without scratching the brushed pattern. Avoid steel wool pads and chlorine-based cleaners, which can damage the passive chromium oxide layer and cause localized pitting. With proper maintenance, the brushed finish maintains its appearance for the service life of the sink.

Accessory Compatibility

Optional accessories for the HA06456 include a custom-fit stainless steel grid that sits on the basin bottom, protecting the surface from cookware impact and elevating dishes above drain water. A basket strainer with removable debris cup fits the standard drain opening. Additional accessories include a colander that nests within the basin rim, a cutting board that spans the basin width, and a drying rack for air-drying utensils and glassware.

For procurement teams outfitting multiple kitchen units, accessories can be bundled with the sink as a single package, reducing sourcing complexity and ensuring accessory compatibility across all installations.

Suitable Project Types

This handmade topmount kitchen sink is specified in multi-unit residential developments where laminate countertops are standard, single-family home renovations where the existing countertop is retained, accessory dwelling units (ADUs) and guest house kitchens with limited counter space, and light-commercial applications such as break room kitchens in office buildings and small café prep areas.

For property developers and kitchen outfitters serving the rental market, the topmount installation reduces installation time and labor cost compared to undermount sinks, as the rim-mounted format does not require countertop edge finishing or under-mount bracket installation. The single-bowl configuration also simplifies plumbing rough-in, requiring only one drain line and one faucet connection.
