Gunmetal Gray Stainless Sink For Vanities That Make a Statement
The Karran Cinox CCU300GG is a rectangular undermount bathroom sink in brushed stainless steel finished in Gunmetal Gray, sized to work in a standard single-basin vanity. It belongs to Karran's Cinox vessel and undermount stainless collection, bringing an industrial-edged finish option to a segment where chrome and matte black usually dominate.
Key Features
• Gunmetal Gray finish gives the brushed stainless surface a cooler, darker tone that coordinates with dark plumbing trim without reading as black.
• Undermount installation keeps the vanity top surface continuous, with no rim collecting water or soap residue around the bowl edge.
• Rectangular bowl profile maximizes usable basin area within the sink's footprint, making it practical for daily grooming as well as aesthetically deliberate.
• 5-1/2 inch bowl depth provides enough working depth for handwashing and face-washing without the basin feeling shallow in use.
• Stainless steel construction from Karran's Cinox collection, a line built specifically for bathroom applications where a metal finish is the design intent.
Where This Sink Fits Best
The Gunmetal Gray finish earns its keep in bathrooms where the hardware palette already runs dark: matte black or gunmetal faucets, dark cabinet pulls, or unlacquered fixtures with a cooler gray cast. It suits primary bathrooms, powder rooms, and master ensuite vanities where the sink itself is a visible part of the design rather than a background fixture. It also fits renovation projects where a client wants a metal-finish basin but not the warmth of gold or the brightness of chrome. Because it installs undermount, the countertop edge — whether stone, quartz composite, or solid surface — is finished and exposed, so the countertop material should be specified for undermount use before cutting.
Material and Finish Details
Stainless steel in a bathroom sink is a different proposition than it is in the kitchen. The Cinox collection treats stainless as a finish material rather than a utilitarian one, and the Gunmetal Gray version carries that logic furthest. The finish is applied over the brushed stainless surface to produce a consistent gray tone across the bowl. Stainless construction resists the moisture environment of a bathroom vanity, and the undermount profile means no rim seams to trap standing water or mildew. The bowl has no faucet holes, so the faucet mounts through the vanity top or through the wall — a standard setup for undermount vanity bowls that keeps the deck clean and gives the installer flexibility on faucet placement.
Specifying and Ordering Considerations
Designers and cabinet shops specifying this sink should confirm the countertop material and fabricator method before cutting. Undermount installation in stone or engineered quartz requires mechanical fasteners or adhesive appropriate to the substrate. No drain assembly is included with this sink — the drain is a separate purchase and should be selected in a finish that complements the Gunmetal Gray bowl. A pop-up drain in Gunmetal Gray or Matte Black finish is the natural pairing. The faucet mounts through the vanity top, so a single-hole or three-hole top is the right deck specification depending on the faucet chosen. Homeowners ordering directly should plan both the drain and the faucet before installation day.
Frequently Asked Questions
Does this sink have an overflow?
No. The Cinox CCU300GG does not have an integral overflow. When selecting a pop-up drain to pair with this sink, choose a drain made for sinks without overflow.
What countertop materials work with this undermount sink?
Undermount installation is appropriate for stone, engineered quartz, and solid surface countertops that are fabricated and finished at the cutout edge. The specific adhesive or clip system should match the countertop substrate — confirm with your fabricator before cutting.
Is a drain assembly included?
No. The drain assembly is sold separately. Plan to order a pop-up drain in a compatible finish alongside this sink.
What faucet configuration does this sink require?
The bowl has no faucet holes, so the faucet mounts through the vanity top. A shorter spout height suits undermount installations; confirm reach and height against the bowl dimensions before specifying the faucet.
Will the Gunmetal Gray finish coordinate with matte black trim?
Gunmetal Gray reads as a cooler, slightly lighter gray compared to true matte black, so the two can read as complementary in the same bathroom rather than identical. For a tight match, compare finish samples before finalizing a hardware spec.
A Vanity Sink That Earns Its Place in the Design
The Cinox CCU300GG in Gunmetal Gray is for bathrooms where the hardware choices are intentional and the finish palette is darker. It installs clean, looks sharp against the right countertop, and gives designers a stainless undermount option that doesn't default to silver.
