Karran Stainless Steel Undermount Sink For Bathroom Vanities
The Karran Edge 300 is an 18-gauge stainless steel undermount vanity sink built for single-bowl bathroom installations where a clean, rimless countertop look is the goal. Its compact footprint fits comfortably in standard vanity bases while still delivering a generous basin depth for everyday use.
Key Features
• 18-gauge Type 304 stainless steel construction provides a solid, durable bowl suited to daily bathroom use.
• Single-bowl layout maximizes uninterrupted basin space within the compact overall dimensions.
• Undermount installation hides the rim beneath the countertop, creating a continuous surface that is easy to wipe clean.
• ADA compliant when installed in accordance with ADA guidelines, making it a viable option for accessible vanity projects.
• No faucet holes on the bowl — the faucet mounts through the countertop or vanity deck, keeping the bowl profile uncluttered.
Where This Sink Fits the Job
Stainless steel reads as a natural fit in bathrooms that pair the vanity with other metal fixtures — brushed nickel faucets, steel-framed mirrors, or industrial-style cabinetry. The Edge 300's single bowl keeps the workspace open, which suits powder rooms and secondary baths where the vanity has to work hard in a small footprint. Because the faucet mounts through the countertop rather than through a deck on the sink itself, this bowl works cleanly with stone, quartz, and solid surface tops where the fabricator drills the faucet holes to the buyer's exact spacing. Undermount installation means the countertop edge finishes to the bowl wall — a detail that makes cleaning the surrounding counter quick and thorough, with no rim ledge to trap water or residue.
Material and Finish
The bowl is formed from 18-gauge stainless steel, which offers the thickness expected in a residential vanity sink. The brushed satin interior finish softens the appearance of minor water marks between cleanings — a practical consideration in a bathroom environment where hard water spotting is common. Stainless steel at this gauge holds its shape under daily use and responds well to standard bathroom cleaning products. As with all stainless fixtures, avoid abrasive pads that can scratch the brushed surface and alter its appearance over time.
Who Should Specify This Sink
Cabinet shops building vanities for renovation or new construction projects will find the Edge 300 straightforward to specify alongside any solid surface, stone, or quartz top. Designers working on accessible bathrooms can include it confidently, provided the install meets ADA clearance and height requirements. Homeowners planning a bathroom refresh who want a clean modern look without the maintenance demands of a china or ceramic bowl will appreciate how stainless ages in a bathroom setting. Contractors looking for a consistent, spec-friendly vanity sink across multiple units in a multifamily or commercial project have a reliable option here.
Frequently Asked Questions
Does this sink include a drain or clips?
The drain assembly and mounting clips are not included with this sink and are sold separately. Confirm your countertop material and fabrication method when selecting clips or adhesive for the undermount installation.
Can this sink be installed in a laminate countertop?
The Edge 300 is an undermount sink. Laminate countertops are not typically recommended for undermount installations because moisture can penetrate the exposed substrate at the cutout edge. This sink is best suited for solid surface, stone, or quartz tops where the edge can be finished to resist moisture.
Where does the faucet mount?
This bowl has no pre-drilled faucet holes. The faucet mounts through the countertop or vanity deck above the sink. Your fabricator will drill the holes to match your chosen faucet's mounting configuration.
Is this sink reversible or handed?
As a single-bowl undermount sink with a centered basin, the Edge 300 does not require orientation — it installs the same way regardless of which side the plumbing enters from below.
A Practical Vanity Sink Built for the Long Run
