A Stainless Undermount Bowl Built for the Vanity
The Karran Edge 309 is an 18-gauge stainless steel undermount sink sized for bathroom vanity installations where clean lines and durability matter as much as looks. Its rectangular single-bowl profile mounts beneath the vanity top to leave a flush, wipe-clean counter edge from deck to bowl.
Key Features
• 18-gauge stainless steel construction delivers a solid, rigid bowl that resists flex and holds its shape over years of daily use.
• Undermount installation conceals the rim beneath the vanity top for a clean, seamless counter surface with no raised lip to trap water.
• Single-bowl rectangular basin provides unobstructed workspace for handwashing, grooming tasks, and routine cleaning.
• Compact footprint at 18-1/8 by 15-3/4 by 5-1/2 inches suits space-constrained vanities without sacrificing usable bowl depth.
• Brushed satin interior finish softens the look of the steel and resists visible water spots and surface scratches from everyday contact.
Where This Sink Fits the Job
The Edge 309 is sized for vanities where a standard kitchen undermount would overwhelm the cabinet run. At just over 18 inches across, it drops into a compact bathroom vanity or a tighter powder room without requiring a large cutout. The 5-1/2-inch bowl depth is deep enough for comfortable handwashing but shallow enough to clear typical under-sink plumbing in a 21-inch vanity cabinet. Designers specifying a consistent stainless finish across a bathroom suite will find the brushed interior coordinates naturally with brushed faucets and accessories.
Material and Finish
Stainless steel at 18 gauge gives this bowl meaningful rigidity for a vanity application. The brushed satin finish runs through the interior of the bowl and reduces the appearance of fine scratches that accumulate with normal use. Because stainless is non-porous, the surface does not harbor soap residue the way some porous materials can, and routine cleaning with a soft cloth and mild cleaner keeps it looking consistent. This sink is intended for indoor bathroom use.
Who Orders This Sink
Cabinet shops fitting out bathroom vanities with a modern or industrial edge reach for this bowl when the client wants stainless rather than china or composite. Contractors sourcing for a guest bath or powder room renovation appreciate the compact dimensions and straightforward undermount install. Homeowners drawn to a professional, utilitarian aesthetic in a bathroom space find that a stainless vanity bowl holds its finish without special maintenance beyond basic wiping. The Edge 309 also works as a second-sink option in a dual-vanity layout where a smaller bowl pairs with a larger primary basin.
FAQ
Does this sink come with a drain assembly?
No drain assembly is included. A compatible 1-3/4-inch vanity drain is a separate purchase and should be selected before finalizing the countertop cutout.
Does the faucet mount through the sink?
There are no faucet holes in the bowl. The faucet mounts through the vanity top or deck behind the sink, so hole count and placement are determined at the countertop fabrication stage.
What is the minimum vanity cabinet size this sink requires?
Confirm the required minimum cabinet size against the Karran spec sheet for the E-309 before ordering, as the cutout dimensions and minimum cabinet depth need to match your vanity.
Is this sink part of the Karran Edge seamless series?
The Edge seamless series (E Series) is engineered for a flush, seamless finish in laminate and solid surface countertops. Confirm the E-309 model documentation for the correct installation method and compatible countertop materials before fabricating the cutout.
Can this sink be used in a kitchen application?
The Edge 309 is dimensioned and positioned as a vanity sink. Its bowl size and depth are suited to bathroom use rather than kitchen prep or dishwashing workflows.
Stainless Where You Need It Most
The Edge 309 brings a consistent, professional finish to bathroom vanities that other materials do not match, and its compact rectangular bowl installs cleanly wherever the countertop demands a crisp, low-profile look.
