15-3/4" Square Undermount Sink For a Clean, Modern Vanity
The Karran Cinox CCU500SS is a square stainless steel undermount bathroom sink sized for compact and single-basin vanity installations. Its perfectly symmetrical footprint and concealed undermount installation make it a natural fit for contemporary and minimalist bathroom designs where the countertop takes center stage.
Key Features
• Square bowl geometry delivers a uniform, architectural look that suits modern vanity tops and custom tile surrounds.
• Stainless steel construction holds up to daily use while keeping the bowl easy to wipe clean.
• Undermount installation positions the bowl beneath the countertop for a seamless, rim-free surface above.
• 5-7/16" bowl depth provides practical capacity for handwashing and grooming routines without overpowering a smaller vanity cabinet.
• No faucet deck on the bowl means the faucet mounts through the vanity top, keeping the bowl perimeter clean and uninterrupted.
Where This Sink Works Best
The square format and stainless finish make this sink an especially strong choice for powder rooms, guest baths, and primary vanities where the countertop material is meant to be the visual focus. Because the rim disappears beneath the stone, quartz, or solid surface top, there is no visible edge to interrupt the countertop plane — just the bowl opening and the stainless interior. It also works well alongside vessel faucets or wall-mounted faucets mounted behind the cutout when no sink deck is available. Designers specifying mixed-material bathrooms — brushed metal fixtures against a matte stone top, for example — often reach for a stainless basin precisely because it coordinates across finish families without committing to a single metal tone.
Material and Finish
The Cinox collection is Karran's stainless steel vessel and vanity sink line, and this model brings that brushed stainless aesthetic to an undermount format. Stainless steel resists moisture and the daily contact of hand soaps, cosmetics, and water without the chipping or crazing risk of ceramic alternatives. The brushed interior finish is consistent with the Cinox collection's tone and masks minor water spots between cleanings better than a mirror-polished surface would. Because this is a stainless sink, standard stainless care applies: avoid harsh abrasives, and dry the bowl periodically to prevent mineral deposit buildup in hard-water areas.
Who This Sink Is For
Cabinet shops and countertop fabricators fitting out a modern bathroom project will appreciate the straightforward undermount geometry — no rim to negotiate, a clean square cutout, and a bowl that drops away from sight once the countertop is in place. Homeowners remodeling a powder room or guest bath get a durable, low-maintenance basin that reads as contemporary without demanding a full bathroom overhaul to match. Designers working with quartz, solid surface, or natural stone tops will find this sink easy to specify: the 15-3/4-inch square footprint works in a wide range of vanity widths, and the faucet-deck-free profile keeps the countertop clean for widespread or vessel-style faucet placements.
Frequently Asked Questions
Does this sink require a special cutout template?
A square cutout at the sink's stated dimensions is needed. Because the sink has a square profile, a CNC template or careful hand layout works well. The actual sink should be present before the countertop is cut to verify the fit.
Where does the faucet mount since the bowl has no faucet holes?
The faucet mounts through the vanity top behind the cutout — not through the sink itself. Single-hole, widespread, and wall-mount faucets all work depending on your countertop configuration and plumbing rough-in.
Is a drain included with this sink?
A drain assembly is not included and should be ordered separately. Standard 1-3/4 inch lavatory drains are the correct size for this bowl.
What countertop materials work with this undermount sink?
Undermount installation is compatible with stone, quartz, solid surface, and similar rigid countertop materials that can support and finish an undermount edge. Laminate countertops are generally not suited to a standard undermount install.
A Stainless Vanity Sink That Stays Out of the Way
The Cinox CCU500SS delivers a clean square basin in brushed stainless, letting the countertop material and faucet do the talking while the bowl handles the daily work reliably.
