Karran undermount vanity sink is a stainless steel single-bowl sink designed for vanity installations where an undermount fit is required. The 17-1/4 inch width provides a compact bowl size that lines up well with typical bathroom countertops while leaving deck space for faucet placement. Its stainless steel construction places it in Karran's Stainless Steel Sinks product class, giving a metal basin option instead of vitreous or composite. The sink is identified as model UV-1816, so it can be specified consistently across drawings and purchase orders. An approximate weight of 22 lbs offers a substantial feel during handling and mounting while remaining manageable for a one-person install. The sink is intended for use in a minimum 21 inch cabinet, so it pairs with common bath vanity widths without crowding interior storage.
This Karran undermount vanity sink uses a rear-center drain configuration sized for a 3-1/2 inch drain opening, which is compatible with most garbage disposals and many standard drain fittings. That opening size simplifies matching common drain components when specifying plumbing layouts. The minimum cabinet size is 21 inches, indicating that standard 21 inch and wider vanity cabinets can accommodate the footprint without encroaching on side panels. The single bowl layout keeps all draining within one basin, which simplifies trap connections below. As an undermount design, the sink sits beneath the countertop, allowing water on the counter surface to flow directly into the basin and giving the vanity a clean edge profile once installed.
This Karran UV-1816 stainless steel sink sits in the Kitchen & Bath Cabinet Accessories, Sinks and Accessories, Sinks category, which places it directly in bathroom and vanity planning workflows. Its 17-1/4 inch width focuses the bowl footprint, supporting installations in compact vanities where counter run is limited. The sink is described as an undermount vanity sink, so it works with solid-surface or stone countertops designed for undermount cutouts. The ultra-durable 16-gauge T304 stainless steel material allows the basin to sit beneath hard countertop materials without concern for mismatch between rigid surfaces. The dark grey metallic look from the PVD coating gives designers another finish option when coordinating with faucets, drains, and cabinet hardware. The embossed hexagonal interior pattern adds structural rigidity, which supports repeated use in residential or light commercial bath environments where the basin experiences daily loading and temperature shifts.
The UV-1816 model number and manufacturer part number UV-1816 provide a consistent identifier across ordering and installation documents, reducing the risk of mixing different sink sizes on multi-unit projects. The minimum 21 inch cabinet size can be referenced during cabinet layout, aligning sink selection with framed or frameless vanity widths so the bowl centers correctly under the faucet. The rear-center drain location opens up more unobstructed space toward the front of the cabinet, which supports cleaner routing of supply lines and storage planning underneath. With a 3-1/2 inch drain opening that is compatible with most garbage disposals, installers using vanities with disposal or similar fittings can rely on the opening size during rough plumbing. The sand-blasted and nano-coated surface, combined with the PVD dark grey metallic finish, supports consistent visual results by resisting water retention and helping the finish maintain its matte character across the full bowl interior.
