A Bold Gunmetal Gray Finish for a Standout Undermount Vanity
The Karran Cinox CCU100GG is a round stainless steel undermount bathroom sink finished in Gunmetal Gray, bringing a darker, more dramatic tone to vanity installations where standard brushed silver would disappear. At 15-3/4 inches in diameter with a 4-3/4 inch bowl depth, it fits cleanly beneath a vanity top and keeps the counter surface uninterrupted from front to back.
Key Features
• Gunmetal Gray finish delivers a moodier, darker alternative to conventional stainless steel without sacrificing the material's durability.
• Round bowl geometry softens the vanity's visual profile and suits circular or oval vanity cutouts.
• Undermount installation positions the bowl beneath the countertop so the deck surface wipes clean with no rim in the way.
• Stainless steel construction resists everyday bathroom wear, including moisture, soap residue, and daily cleaning.
• No faucet holes on the bowl means the faucet mounts through the vanity top or a wall, keeping the bowl profile clean.
Where This Sink Works Best
The Cinox Gunmetal Gray is a natural fit for moody, design-forward bathrooms — think dark-stained vanity cabinets, matte black hardware, or honed charcoal stone countertops. The finish bridges the gap between industrial stainless and matte black, making it easier to pull together a layered, contemporary look without mismatched tones. It also performs well in spa-style bathrooms where the goal is visual restraint: the round form and consistent gunmetal surface read as considered and quiet rather than loud.
The undermount configuration suits solid surface, stone, and quartz vanity tops where a polished edge detail around the cutout is part of the design. Because there is no rim sitting on the counter, there is also no ledge to trap toothpaste or soap — a practical benefit that matters in a busy household bathroom as much as a designed one.
Stainless Steel in a Finish That Holds Its Own
Stainless steel as a vanity bowl material brings real-world resistance to the conditions bathrooms deliver daily: standing water, cleaning products, and frequent contact. The Gunmetal Gray finish gives the Cinox collection its distinctive look. As with all colored faucet and sink finishes, pair it thoughtfully with other fixtures in the space — Gunmetal Gray coordinates well with matte black and dark bronze family finishes, but an exact cross-brand finish match is never guaranteed.
The bowl has no faucet holes, so the faucet mounts through the vanity top above it. A taller, slender faucet suits the round bowl's geometry. Drain assembly is not included with the sink and should be ordered separately to match the finish and confirm compatibility with a 1-3/4 inch drain opening.
Who Specifies the Cinox Gunmetal Gray
Designers working on dark, layered bathroom palettes reach for the Cinox Gunmetal Gray when they need a sink finish that commits to the direction rather than defaulting to silver. Cabinet shops finishing custom vanity commissions appreciate that the undermount bowl delivers a clean, fabricated look without requiring specialty countertop materials. Contractors sourcing for a renovation where the client has already chosen matte or dark hardware throughout will find the Gunmetal Gray a reliable match anchor for the rest of the space.
Frequently Asked Questions
Does this sink include a drain assembly?
No. The drain assembly is sold separately. The bowl has a 1-3/4 inch drain opening, which is standard for lavatory sinks — order a pop-up drain in a compatible finish to match the faucet.
What countertop materials work with an undermount installation?
Undermount sinks attach beneath the countertop and work well with solid surface, stone, and quartz tops where the cut edge can be finished and sealed. The countertop fabricator sets and clips the bowl from below.
Where does the faucet mount if the bowl has no holes?
Through the vanity top above the bowl. Your countertop fabricator or installer drills the faucet hole to match the faucet's mounting requirement — single-hole, widespread, or wall-mount.
How does Gunmetal Gray compare to the Stainless Steel finish in the Cinox line?
The Gunmetal Gray is a darker, warmer-toned surface compared to the standard brushed stainless finish. It reads as closer to matte charcoal than silver, which suits bathrooms built around dark or matte hardware palettes.
The Right Sink for a Considered Bathroom Design
The Cinox Gunmetal Gray undermount sink gives designers and builders a stainless steel lavatory that earns its place in a dark, deliberate bathroom scheme — not just a functional bowl, but a finish choice that holds the room's palette together.
