Bold Color and Above-Counter Impact
The Karran Sternhagen SQS300BL is a vessel-mount, single-bowl bathroom sink in quartz composite, finished in Black. It sits above the vanity surface for a commanding presence on the countertop, and its elongated 32-1/8 by 18-1/4 inch footprint gives the bowl a sculptural scale that reads as a design centerpiece rather than a standard lavatory fixture.
Key Features
• Vessel mounting positions the bowl on top of the vanity surface, with no countertop cutout required beyond the drain opening.
• Quartz composite construction combines natural quartz crystals and acrylic resin for a material that is highly scratch, stain, chip, and heat resistant.
• Black finish is a molded-through color, not a surface coating, so the tone runs consistent throughout the bowl.
• Single-bowl configuration delivers an uninterrupted interior for an uncluttered, easy-to-clean basin.
• Low-profile 5-1/8 inch depth keeps the bowl's silhouette lean while still offering practical interior volume.
Where This Sink Works Best
This sink is well-suited to a bathroom where the vanity is meant to stand out. The Black quartz composite reads well against light-toned stone or solid surface tops, where the contrast becomes a deliberate design move rather than a background detail. The elongated rectangular form also works in master bath layouts with wider vanities, where a narrower round vessel would look undersized. Designers specifying a moody, tonal palette and contractors building high-finish primary baths will both find the proportions and color work at that scale.
Because this is a vessel sink, the faucet mounts through the vanity top rather than through the bowl, and taller vessel-height faucets are the right pairing to clear the bowl's rim comfortably. Plan faucet selection around the bowl's above-counter height before finalizing the vanity top drilling.
Material Built for Daily Use
The Sternhagen collection uses Karran's quartz composite, an 80% natural quartz and 20% acrylic resin blend that the manufacturer describes as highly resistant to scratches, stains, chips, and heat. The Black color is inherent to the material mix, which means minor surface contact leaves no visible wear through a coating layer. The non-porous quartz composite surface does not absorb soap residue or hard water deposits the way a porous material would, and it cleans without specialized products. The 5-1/8 inch bowl depth keeps the interior volume manageable for a single-person lavatory without making the vessel look undersized on a full-width vanity top.
For Designers, Builders, and Discerning Renovators
Design professionals specifying a full bathroom renovation will appreciate that the Sternhagen's Black quartz holds its finish across the install's lifespan without the polishing or re-sealing a stone surface would require. Cabinet shops finishing out vanity builds can offer this vessel as a high-impact upgrade over a standard undermount. Homeowners refreshing a primary or guest bath get a fixture that changes the room's character without a full rebuild. The vessel format also keeps the countertop fabrication straightforward: the top surface remains largely uncut, which simplifies templating and reduces the chance of a fabrication error at the cutout edge.
Frequently Asked Questions
Does this sink include a drain assembly?
No drain assembly is included. A separate vessel drain sized for the bowl's drain opening is required to complete the installation.
Does the Black color run through the material or is it a surface finish?
The Black is molded into the quartz composite blend rather than applied as a coating, so the color is consistent through the bowl wall.
What faucet height works with this vessel sink?
Vessel sinks require a taller vessel-height faucet or a wall-mount faucet to reach comfortably over the bowl's rim. A standard short-reach faucet will not clear the bowl.
Is this sink suitable for countertop materials other than solid surface or laminate?
As a vessel sink, it rests on top of the vanity surface, so countertop material compatibility is primarily about the drain opening cut rather than the sink mounting method. Consult your fabricator for the drain cutout on stone, solid surface, or laminate tops.
Can this sink be used in a commercial bathroom?
The product data does not include a commercial rating or code listing for this model. Confirm compliance requirements with the specifying authority for commercial or ADA-regulated applications before ordering.
A Statement Fixture That Stays Practical
The Sternhagen in Black delivers the visual impact of a design-forward vessel sink alongside a quartz composite construction that holds up to the actual demands of a daily-use bathroom, so the room looks as good in year five as it did at install.
