20英寸方形陶瓷台上盆，深壁台面上置白色盆体

The SANIKB 20 inch rectangular ceramic vessel sink is an above-counter basin built for distributors, importers, private-label brands, and project buyers across North America. Its clean rectangular profile and 140mm (5.5") basin height suit residential remodels, multifamily and build-to-rent units, hospitality guest baths, and showroom displays. The 20-inch designation is nominal; the actual width is 500mm (19.7"). As a factory-direct OEM/ODM product, it is available for bulk supply, recurring project orders, and private-label programs.

This 500mm rectangular ceramic vessel sink is sized for predictable countertop layout and repeatable installation across multiple units.

• Overall dimensions: 500 × 395 × 140 mm (19.7" × 15.6" × 5.5")
• Inner basin opening (length): 470 mm (18.5")
• Wall thickness: 15 mm (0.6")
• Drain opening: Ø45 mm (1.8") inner bore, Ø70 mm (2.8") outer
• Drain configuration: single drain, no overflow
• Faucet drilling: none (wall-mount or counter-mount faucet)
• Mounting: above-counter (vessel)

Because every unit shares the same footprint and drain geometry, the basin is straightforward to specify across large orders.

This vessel sink has a single drain and no overflow, which is standard for above-counter ceramic basins of this type. It is designed to accept a non-overflow drain, such as a grid (umbrella) strainer or a click-clack pop-up, sized for the Ø45mm (1.8") opening. Buyers specifying drains for a full order should confirm a non-overflow model, since pop-ups with overflow ports are not required and will not seat correctly. Drain hardware can be quoted alongside the basins on request.

The sink ships without a pre-drilled faucet hole. It pairs with a wall-mounted faucet or a counter-mounted vessel (tall-body) faucet chosen to clear the 140mm (5.5") basin height and the rim. It installs above the counter, so the countertop requires only a cutout for the drain and any mounting hardware rather than a full basin drop-in. The drain sits off-center on the basin, which installers should account for when locating the cutout and rough-in. For multifamily and hospitality rollouts, the above-counter format keeps countertop fabrication simple and consistent across identical units.

The basin is made from glazed ceramic with a smooth surface that wipes clean and presents a consistent glazed finish. The rectangular form gives it a clean, contemporary look suited to both residential and light-commercial vanities. Finish and color options are confirmed at quotation, so private-label and project buyers can align the basin with a specified design package.

SANIKB manufactures this basin factory-direct and supports OEM and ODM production for buyers building their own brand or catalog. Custom branding, neutral or branded packaging, and rebrandable spec sheets are available so the product can be sold under your own name. Each ceramic unit is packed for export handling to reduce breakage in freight and warehouse transfer, with packaging details and protection confirmed for your shipping method. Minimum order quantity, lead time, and pricing are confirmed at quotation based on configuration, finish, and branding requirements.
