22英寸圆角长方形陶瓷台上盆，柔角白色盆体

The defining feature of this rounded corner ceramic vessel sink is its proportion: a wide rectangular footprint with corner radii that soften the form. The straight, tapered walls give it an open basin suited to above-counter use.

Verified dimensions:

• Overall size: 555 × 420 × 145 mm (21.9 × 16.5 × 5.7 in), width × depth × height
• Interior basin opening: 515 × 380 mm (20.3 × 15 in)
• Wall thickness: 20 mm (0.8 in)
• Overall height: 145 mm (5.7 in)

The marketed 22 inch designation reflects a true width of 21.9 in (555 mm). For submittals, takeoffs, and countertop cutting, use the exact figures above. Full dimensional drawings are provided on request for specification packages.

This is an above-counter vessel. It rests on the finished countertop surface and connects to the drain plumbing beneath, which keeps installation flexible across standard vanity tops and custom surfaces.

The drain outlet is Ø45 mm (1.8 in), with an outer recess of Ø70 mm (2.8 in) at the base, and is positioned approximately at the center of the basin. The exact cutout location is given in the dimensional drawing. The spec drawing shows no overflow, so the basin pairs with a standard non-overflow vessel drain, either a grid or a pop-up without overflow. If a run requires an overflow port, we confirm that when we quote.

Because the basin sits above the counter, pair it with a tall deck-mount vessel faucet or a wall-mount faucet sized for vessel height. Faucet and drain hardware are quoted separately unless bundled by agreement, so confirm the pairing on your order to ensure deck height and reach suit the installation.

The rounded rectangular profile is a versatile specification across commercial and residential project work:

• Hospitality FF&E: guest bathrooms and public restrooms where one vessel repeats consistently across many keys
• Multifamily and build-to-rent: unit bathrooms that repeat a single fixture across a large count, where run-to-run consistency is reviewed and confirmed before production
• Showroom dealers: a clean, modern vessel to merchandise and pair with countertop and faucet displays
• Distributors and importers: a catalog-ready ceramic vessel with documented dimensions for resale
• Private-label brands: a neutral shape suited to own-brand programs
• E-commerce resellers: a defined-dimension vessel for marketplace listings, with export packaging to protect ceramic in transit

For project buyers, the priorities we plan around are consistency from run to run and delivery that holds to a construction schedule.

SANIKB manufactures this vessel sink factory-direct and supports OEM and ODM programs. Customization scope, including finish options, branding, and carton and insert design for private-label programs, is defined per project. Where a buyer needs a configuration outside the standard unit, we review feasibility before the order is placed.

Export packaging is built to protect glazed ceramic through ocean and parcel freight, with carton specifications and palletization specified per order. Spec sheets and dimensional drawings support submittals and listings.

MOQ, pricing tiers, and lead time depend on configuration, finish, and order volume, and are set at the quotation stage. To move forward, send your target quantity, destination, and any branding or finish requirements through the RFQ process for a tailored quote.
