Karran Matrix 17 W gunmetal undermount sink is a single-bowl stainless steel sink that serves bar, prep, or compact kitchen runs where space is tight but function still matters. The sink is crafted from ultra-durable 16-gauge T304 stainless steel, so the bowl resists flexing during everyday use, which supports solid-feeling faucet and disposer installs. The interior has an embossed hexagonal pattern that adds structural rigidity to the basin, which helps the sink hold its shape under heavier pots and pans. That same pattern also reduces visible wear over time, so high-contact areas in busy prep zones show less scuffing. A special Physical Vapor Deposition PVD coating creates the sleek, dark grey metallic gunmetal look, giving projects a distinct visual contrast against typical stainless. This makes the sink a good fit when the design calls for a darker, more modern metal finish.
This Karran Matrix undermount sink is intended to install beneath the countertop, so the finished edge presents a clean, flush transition for wiping crumbs and liquids straight into the bowl. The single-bowl format concentrates working room into one cavity, simplifying cutout layout in tight bar or prep runs. With a minimum cabinet size of 36 inches, this sink is sized for standard base cabinet widths common in kitchen and bar layouts, which helps align it with typical stock or semi-custom cabinetry. The drain opening size of 3-1/2 inches matches the common industry standard, providing compatibility with most garbage disposals by design. The approximate weight of 40 lbs gives the sink a substantial feel once mounted, which supports a solid, rattle-free installation under stone or solid-surface tops in working environments.
This Karran HSU1717SBGG stainless steel sink is well suited for bar stations, prep zones, or smaller secondary kitchen counters where a 17 inch bowl gives concentrated workspace without dominating the cabinet run. The undermount configuration lets the counter material be the visible perimeter, which suits stone and solid-surface tops in higher-end projects. The dark gunmetal PVD finish pairs effectively with darker cabinetry and fixtures, giving contrast to lighter countertops or tying into black and graphite appliances. The embossed hexagonal pattern inside the bowl adds visual depth, which helps the sink present as a deliberate design element in open-plan kitchens and entertainment spaces. With its stainless steel construction, the sink integrates into woodworking and cabinet projects that lean on metal components for long-term durability in wet areas.
The rear-center drain layout on this rear center drain undermount sink shifts the plumbing toward the back of the cabinet, which keeps more open volume in front for pull-out bins or storage and simplifies trap placement around nearby drawers. The 3-1/2 inch drain opening gives a straightforward interface when specifying strainers or garbage disposals, limiting special-part callouts in project notes. The sand-blasted and nano-coated surface combination speeds water shedding from the bowl, so installers and users get less standing water hiding debris at the perimeter after rinsing. The 16-gauge T304 stainless shell resists deformation at the rim and bowl, which is helpful when tightening clamps or supports during undermount installation. The gunmetal finish created by the PVD process stays visually consistent across the interior, giving trades and serious DIY users a controlled, predictable appearance once the sink is in service.
