Gray Quartz Vessel Sink for a Design-Forward Vanity
The Karran Sternhagen SQS300GR is a large-format quartz composite vessel sink that rests above the vanity surface, making the bowl itself a visual centerpiece. In a warm Gray finish, it brings depth and texture to bathroom designs that call for more than a standard white basin.
Key Features
• Quartz composite construction blends 80% natural quartz crystals with 20% acrylic resin for a dense, durable bowl.
• Gray finish provides a rich, neutral tone that pairs with wood tones, concrete surfaces, and matte metal hardware.
• Vessel mount installation positions the bowl above the countertop for a bold, furniture-like vanity presentation.
• Single-bowl configuration delivers an uninterrupted basin well-suited to a primary or guest bathroom vanity.
• Highly scratch, stain, chip, and heat resistant surface holds up to daily grooming routines without showing wear.
• Part of the Sternhagen quartz vessel collection by Karran, offering a coordinated family of vessel designs in multiple finishes.
Above the Counter, by Design
Vessel sinks occupy a different visual space than undermount or drop-in bowls. Because the basin sits proud of the deck, the countertop functions as a platform rather than a working surface, and the sink becomes the room's focal point. The Sternhagen's generous proportions support that role without overwhelming a standard vanity footprint. Its single bowl offers ample room for daily use, and the absence of deck faucet holes keeps the countertop surface clean. The faucet mounts through the vanity top, so the pairing choice matters: a tall vessel-height faucet is required to clear the bowl's rim and reach the basin comfortably.
Quartz Composite Built for a Bathroom That Gets Used
The Sternhagen collection is built from Karran's quartz composite material, an 80/20 blend of natural quartz crystals and acrylic resin. That composition produces a bowl that is highly resistant to scratches from everyday toiletries, staining from soaps and cosmetics, chipping at the rim, and heat from styling tools. Unlike glazed ceramics, which show crazing and chipping at cut edges over time, the quartz composite is consistent through its full depth. The Gray colorway is integral to the material rather than a surface coating, so minor scuffs do not expose a contrasting layer underneath. Care is straightforward: routine cleaning with a non-abrasive cleanser keeps the surface looking its best.
The Right Sink for Bathrooms That Prioritize Appearance
Interior designers specifying a spa-inspired primary bath, contractors finishing a high-end remodel, and homeowners who want the vanity to read as a piece of furniture rather than a utility fixture all land on vessel sinks for the same reason: the bowl above the counter changes the room's character. The Gray finish is especially effective in bathrooms that mix natural materials — wood vanities, linen wall treatments, concrete tile — where a bright white sink would feel out of place. Cabinet shops building custom vanities can size the top to this sink's footprint and let the bowl drive the aesthetic. Because the Sternhagen is part of a coordinated collection, matching vessel bowls are available in additional finishes for projects where multiple bathrooms need to hold a consistent design language without being identical.
Frequently Asked Questions
Does the Gray finish match Karran's quartz kitchen sinks in Grey?
Karran uses "Gray" for Sternhagen vessel finishes and "Grey" (abbreviated GR) for its quartz kitchen and farmhouse sink color family. The underlying color is similar, but because the Sternhagen and the kitchen quartz lines are separate collections with different molding processes, an exact finish match across product families cannot be guaranteed. If color coordination across a kitchen and adjacent bath is a priority, request physical samples before specifying both.
Is a drain included with this sink?
No drain assembly is included. A compatible vessel drain or pop-up drain should be ordered separately to complete the installation.
What faucet height is needed for this vessel sink?
Because the bowl sits above the countertop surface, a standard short faucet will not clear the rim. A faucet designed for vessel installation — with sufficient spout height to reach into the basin — is required. Verify the faucet's spout height and reach against the sink's 5-1/8 inch bowl depth before ordering.
Does this sink have a faucet hole or an overflow?
The Sternhagen vessel bowl has no pre-drilled faucet holes and no integral overflow. The faucet mounts through the vanity top or countertop, and drain selection should account for the absence of an overflow port.
What countertop materials work with this vessel sink?
Because this is a vessel mount sink that rests on top of the surface, it is compatible with virtually any countertop material capable of supporting its weight and accommodating the drain cutout. The countertop edge finish and thickness remain fully visible around the bowl, so the deck material choice is part of the visual composition.
A Vanity That Makes an Impression
The Sternhagen in Gray delivers the presence of a statement fixture with the durability of a material built for daily use — the kind of combination that earns a second look in a showroom and holds up to real bathroom routines for years.
