18-Inch Cylindrical Round Ceramic Vessel Sink Bowl

Built to a compact round footprint, the SN134-537C carries the following confirmed specifications:

• Overall outer diameter: 18 1/8 in (460 mm)
• Overall exterior height: 5 3/4 in (145.5 mm)
• Inner basin diameter: approximately 16 1/2 in (420 mm)
• Wall thickness: 0.8 in (20 mm)
• Drain opening: 1.8 in (45 mm), seated in a 2.8 in (70 mm) recess
• Mounting: above-counter vessel with a single center drain

The basin has no overflow and a single center drain, so it pairs with a free-flow (non-overflow) pop-up drain rather than a standard overflow-style fitting. Confirming the correct drain at the specification stage avoids mismatched accessories and field callbacks.

The body is glazed ceramic in white. The glazed surface is smooth and easy to wipe clean, and the neutral white finish coordinates with a broad range of countertop materials and fixture finishes, which makes the cylindrical vessel basin straightforward to specify across multiple projects or a private-label range. For volume orders that require strict finish matching across production runs, request a current sample so the approved standard is documented before production.

The SN134-537C sits on top of the counter as a vessel basin, with the drain routed through a single center opening into the cabinet below. Because the basin raises the rim well above the counter surface, it is typically paired with a tall vessel-style faucet or a wall-mounted spout sized to clear the 5 3/4 in (145.5 mm) overall height. Standard deck-mounted faucets usually sit too low for comfortable use with an above-counter basin.

This round ceramic vessel sink suits a range of B2B programs. Distributors and importers can stock it as a core above-counter SKU, while private-label brands can build it into a branded bathroom range. The form factor works for multifamily and build-to-rent units, hospitality guest baths, showroom displays, and e-commerce listings where a clean, photogenic above-counter basin supports the catalog.
