A Compact Undermount Lavatory Built for Refined Bathroom Vanities
The Karran VC-105-WH is a single-bowl vitreous china undermount sink sized at 18 by 13 by 5-3/4 inches, designed to fit neatly beneath a vanity top while keeping the counter surface clean and uninterrupted. Its rectangular form suits both new vanity builds and countertop replacements where a flush, rimless installation is the goal.
Key Features
• Double-glazed vitreous china construction delivers a dense, high-gloss white finish that resists stains, scratches, and scuffs through daily use.
• Undermount installation conceals the bowl rim beneath the vanity top, producing a smooth counter edge with no crevice to trap water or debris.
• Single-bowl rectangular basin provides a focused wash area well matched to compact and standard bathroom vanities.
• White finish coordinates cleanly with a broad range of faucet and hardware finishes across Chrome, Matte Black, Brushed Gold, and more.
• ADA-compliant when installed in accordance with ADA guidelines, supporting accessible vanity configurations for residential and commercial settings.
Where This Sink Fits the Job
At 18 by 13 inches, this bowl works especially well in guest bathrooms, powder rooms, and master vanities where counter real estate is shared with a faucet and accessories mounted through the vanity top. The undermount method suits solid surface, stone, and quartz countertops, where a finished edge against the bowl rim delivers the wipe-clean surface that homeowners and designers favor. Because the faucet mounts through the countertop rather than the sink deck, the bowl is compatible with widespread, centerset, and single-hole faucet configurations as long as the vanity top accommodates the drillings. Cabinet shops building custom vanity cases will find the rectangular footprint straightforward to plan around, and contractors retrofitting an existing top need only confirm the cutout dimensions before ordering.
Material and Finish
Vitreous china is fired ceramic with a glassy glaze that bonds to the body during kiln firing rather than being applied as a surface coating. Karran's Valera Collection double-glazes the material, adding a second fired layer that increases the density and uniformity of the gloss. The result is a surface that holds its white appearance under routine bathroom use, resisting the stains and scuffs that wear softer finishes over time. The White finish is consistent across the bowl interior and exterior, so it reads cleanly from every angle during installation. Because the material is non-porous at the glaze layer, standard bathroom cleaners maintain it without special products or periodic resealing.
Who This Bowl Is For
Designers specifying a classic, long-wearing lavatory without a heavy price premium will find the double-glazed china surface delivers the high-gloss look expected in a well-finished bathroom. Homeowners renovating a guest bath or powder room get a durable, easy-to-clean bowl that holds up through years of use. Cabinet shops and contractors doing full vanity builds appreciate that the rectangular form integrates predictably into the cutout layout, and that the ADA-conditional compliance opens this sink to accessible build projects when the installation meets the required guidelines. The undermount style is the natural choice anywhere a clean counter transition matters more than the ease of a drop-in rim.
FAQ
Does this sink include a drain assembly?
No. The drain assembly is sold separately. You will need a pop-up drain or lavatory drain sized for a standard 1-3/4 inch drain opening to complete the installation.
Does this bowl have faucet holes?
No. As an undermount design, the faucet mounts through the vanity top rather than through the sink. This gives you full flexibility over faucet style and hole configuration when you fabricate or select the countertop.
What countertop materials work with an undermount china sink?
Undermount sinks pair most reliably with solid surface, natural stone, engineered quartz, and similar countertop materials that can be finished at the cutout edge. Laminate is not typically recommended for undermount installations because the exposed edge is difficult to protect from moisture.
Is this sink ADA compliant?
It is ADA compliant when installed in accordance with ADA guidelines. Compliance depends on the finished installation height and knee clearance, not the sink alone, so the full vanity configuration must meet the applicable requirements.
Does the double glaze require any special maintenance?
No special maintenance is required. Standard non-abrasive bathroom cleaners keep the surface in good condition. Avoid harsh abrasive pads, which can dull the glaze over time.
A Lasting Finish in a Form That Works
The VC-105-WH delivers a clean, durable undermount lavatory in a size that suits the widest range of bathroom vanity builds, backed by Karran's double-glazed vitreous china construction and ADA-conditional compliance for accessible projects.
