A Stainless Undermount Bowl That Anchors a Moody, Design-Forward Vanity
The Karran Cinox CCU400GG brings a brushed stainless steel construction and a Gunmetal Gray finish together in a rectangular undermount bowl sized for a confident, contemporary vanity. It installs beneath the countertop, leaving the deck surface uninterrupted and the clean geometry of the bowl on full display.
Key Features
• Gunmetal Gray finish gives the bowl a deep, matte-toned presence that pairs naturally with dark hardware and matte stone surfaces.
• Brushed stainless steel construction provides a non-porous surface that cleans easily and holds up to daily bathroom use.
• Undermount installation places the bowl flush beneath the vanity top so no rim breaks the countertop surface.
• Rectangular bowl profile offers a defined, architectural shape suited to modern and transitional vanity designs.
• No faucet holes on the bowl means the faucet mounts through the vanity top, keeping the rim line uncluttered.
• 1-3/4 inch drain opening accepts standard lavatory pop-up drains, sold separately.
Where This Bowl Fits the Project
This sink is built for vanity installations where finish coordination matters as much as function. Gunmetal Gray works with matte black fixtures, brushed brass, and unlacquered metals without competing with them, making it a natural choice for a primary bathroom or powder room with a deliberate, curated palette. Because the faucet mounts through the countertop rather than the bowl, the deck stays clear regardless of the countertop material. Undermount installation suits solid surface, stone, and engineered quartz tops where a continuous, wipe-clean deck is the goal. The rectangular profile holds its proportions in a 24-inch or wider single-sink vanity, and the 5-7/16-inch bowl depth gives enough capacity for a working bathroom sink without dominating a shallow vanity cabinet.
Stainless Construction in a Finish Built for Contrast
Stainless steel in a bathroom sink earns its place through durability and ease of cleaning. The Cinox bowl's brushed surface resists water spots and fingerprints better than a polished finish, and the non-porous material does not harbor mold or mildew at the bowl wall. The Gunmetal Gray finish elevates the material beyond a utilitarian choice: it reads as intentional, sitting in the same tonal range as matte graphite tile, dark cement board, and blackened metal fixtures. The finish is consistent across the bowl interior and exterior, so it looks finished from above and from the side where the apron is visible in an open or floating vanity. This is a stainless sink for a bathroom where stainless is a style decision, not a fallback.
Who Orders This Bowl
Designers specifying a guest bath or primary bathroom remodel reach for this bowl when the project calls for a dark, cohesive metal palette and a faucet deck with no visible penetrations at the rim. Cabinet shops and contractors handling vanity installations appreciate that the rectangular undermount profile is straightforward to template and set, with no curved apron or unusual geometry to account for at the cutout. Homeowners upgrading an existing vanity can use this bowl anywhere the countertop can be cut for an undermount and the plumbing can be connected to a separate pop-up drain. A drain assembly is not included and should be ordered alongside the sink.
Does the drain ship with the sink?
No. The drain assembly is sold separately. Order a standard 1-3/4 inch lavatory pop-up drain that matches your chosen faucet finish or coordinates with the Gunmetal Gray bowl.
Where does the faucet mount?
Through the vanity top or countertop, not through the bowl. This keeps the sink rim clean and gives you flexibility over hole count and faucet style. A single-hole, centerset, or widespread faucet all work depending on how the top is drilled.
Is this sink a good match for a floating or open vanity?
Yes. Because the Gunmetal Gray finish covers the bowl exterior as well as the interior, the outside of the bowl looks intentional where it is visible below an open or floating vanity deck.
What countertop materials work with this undermount installation?
Solid surface, natural stone, and engineered quartz are the materials best suited to undermount installation. The installer should template and cut the top with the actual sink present before making the final cutout.
A Finish Worth Specifying by Name
When the vanity design calls for a sink that commits fully to a dark metal aesthetic, the Cinox CCU400GG in Gunmetal Gray delivers the finish and the form to make that decision hold up across the life of the project.
