Brushed Stainless Basin And a Clean Undermount Fit
The Karran Cinox CCU400SS is a rectangular stainless steel undermount bathroom sink sized to bring a professional, furniture-grade look to vanity installations that call for a finished, rimless basin. Clean lines and a brushed stainless finish make it a natural choice where contemporary design and everyday durability need to coexist in the same space.
Key Features
• Undermount installation leaves no exposed rim above the vanity top, keeping the counter easy to wipe clean.
• Rectangular bowl profile delivers a sharp, contemporary aesthetic that works with both stone and solid surface tops.
• Brushed stainless steel finish blends with a wide range of hardware and faucet finishes without calling attention to water spots.
• Generous 5-7/16 inch bowl depth gives users practical working room at the vanity without looking oversized.
• Part of Karran's Cinox vessel collection, a coordinated stainless line that spans multiple basin styles for a cohesive bath design.
Where This Sink Fits the Work
Undermount installation is the right call when the countertop is doing design work of its own. With no rim sitting proud of the surface, the vanity top runs uninterrupted to the bowl edge, which makes both the sink and the stone easier to appreciate. This basin is particularly well suited to solid surface and natural stone countertops, where an adhesive-bonded undermount installation produces a clean, sealed joint. Because the faucet mounts through the countertop rather than through a deck on the bowl, the hardware selection stays flexible and the plumbing layout stays tidy beneath the vanity.
At 23-5/8 inches long and 15-3/4 inches wide, this is a full-size lavatory bowl suited to a primary bath or a high-use powder room where a compact vessel would feel cramped. The rectangular footprint keeps it readable in the layout drawings cabinet shops and designers use for specifying custom vanity builds.
Stainless in a Bathroom Context
Stainless steel in a bath setting reads differently than it does in a kitchen. Here it reads architectural: the brushed Stainless Steel finish of the Cinox bowl sits alongside brushed hardware, matte fixtures, and warm wood cabinetry without competing. The material is non-porous, holds up to hand soaps and grooming products that would stain softer surfaces, and does not require the careful drying routine that polished or enameled basins can demand. The Cinox collection carries the same stainless construction across its line, so the CCU400SS can be paired with a coordinating Cinox vessel bowl at a second vanity in the same bath and the finishes will read as a matched set.
Who Specifies This Bowl
Cabinet shops building custom or semi-custom vanity boxes will find the rectangular format straightforward to spec: the undermount clips into the underside of the top, and the clean outline photographs well for portfolio work. Designers specifying a contemporary or transitional primary bath reach for brushed stainless when they want a material that won't date as quickly as a trend-color composite. Contractors handling a bath remodel or new construction with a stone or solid surface top can install this bowl using the same undermount process they already know. The 5-7/16 inch bowl depth keeps daily use practical without requiring a deeper vanity than a standard build provides.
Frequently Asked Questions
Does this sink have pre-drilled faucet holes?
No. As an undermount bowl, the Cinox CCU400SS has no faucet deck and no pre-drilled holes. The faucet, soap dispenser, and any other accessories mount through the countertop behind the bowl.
Is a drain assembly included?
A drain assembly is not included with this sink and must be purchased separately. Select a lavatory drain compatible with the 1-3/4 inch drain opening standard to this bowl size.
Does the bowl have an integral overflow?
The product data for this SKU does not confirm an integral overflow. Verify the overflow configuration before selecting a drain so the drain type matches the bowl.
What countertop materials work with this undermount installation?
This sink is suited to solid surface, natural stone, and quartz countertops where an undermount bond can be properly made. The fabricator should follow the countertop manufacturer's recommended method for undermount attachment.
Can I use a standard-height bathroom faucet with this sink?
Yes. Because this is an undermount bowl rather than a vessel, a standard-height single-hole or deck-mount faucet installed through the countertop works well with this sink.
A Vanity Bowl That Pulls Its Weight Every Day
The Cinox CCU400SS delivers a crisp, rimless look without asking the countertop fabricator or the installing contractor to do anything unusual. Brushed stainless, a full-size rectangular bowl, and a straightforward undermount process add up to a vanity sink that holds its appearance over years of daily use.
