18-Gauge Stainless Steel Vanity Sink For Undermount Bath Installations
The Karran E-505 is an 18-gauge stainless steel single-bowl lavatory designed for undermount installation in bathroom and powder room vanities. Its square bowl profile and compact footprint suit a range of vanity sizes while delivering the clean, wipe-easy surface that stainless steel brings to the bathroom.
Key Features
• 18-gauge stainless steel construction provides a durable, corrosion-resistant bowl that holds up to daily bathroom use.
• Single square bowl configuration maximizes usable basin space within the sink's compact overall dimensions.
• Undermount installation mounts beneath the vanity top so no rim is visible from above, making the counter easy to wipe clean.
• ADA-compliant profile supports accessibility-conscious installations when installed in accordance with ADA guidelines.
• No faucet holes on the bowl means the faucet and any accessories mount through the vanity top, giving fabricators and designers full control over faucet placement.
A Clean Work Surface From Counter to Bowl
Undermount sinks earn their place in bathroom design by eliminating the rim that collects water and soap residue on a drop-in. With the E-505 tucked beneath the vanity deck, the countertop edge finishes cleanly into the bowl opening — a practical advantage on a surface that sees toothpaste, hand soap, and daily splashing. Because the faucet mounts through the countertop rather than the sink itself, the layout is flexible: a single-hole faucet, a widespread set, or a wall-mount all work without the sink dictating the choice. The 18-1/4 by 15-7/8 inch overall footprint fits comfortably in standard 21-inch-deep vanity bases, and the 5-1/2-inch bowl depth is adequate for handwashing without the bulk of a kitchen-style basin.
Stainless Steel in the Bathroom Context
Stainless steel is less common in bath vanities than vitreous china or composite materials, and that scarcity works in its favor for certain design directions. The brushed surface reads as intentional and contemporary alongside matte black or brushed hardware finishes. The 18-gauge steel is substantial enough to resist flex and dampen sound, and the material is nonporous and easy to maintain with routine cleaning. The square bowl shape reinforces a geometric, architectural aesthetic that suits modern and industrial-style bathrooms where a china oval would feel out of place.
Where the E-505 Fits
This sink is a natural match for powder rooms, guest baths, and primary vanities where contemporary styling drives the design. Fabricators working in solid surface, quartz, or stone countertops will find the undermount install straightforward, and the absence of a faucet deck leaves the countertop material uninterrupted. Design professionals specifying accessible bathrooms can include this sink in ADA-compliant layouts when the installation follows ADA guidelines. Cabinet shops building vanity boxes benefit from the compact sizing, which opens up cabinet options beyond the widest sink bases.
Does this sink include a drain or mounting hardware?
The E-505 does not include a drain assembly. A separate lavatory drain sized for a 1-3/4-inch drain opening should be ordered to complete the installation. Confirm mounting hardware requirements with your countertop fabricator, as undermount attachment method varies by countertop material.
What countertop materials work with this undermount sink?
Stainless undermount sinks are well suited to solid surface, quartz, granite, and stone countertops where the edge can be finished cleanly. Installation method and clip or adhesive choice depend on the countertop material and the fabricator's process.
Is this an ADA-compliant sink?
The E-505 is ADA compliant when installed in accordance with ADA guidelines. Compliance depends on installation conditions — bowl height, knee clearance, and related factors — not on the sink alone.
What faucet configuration does this sink accept?
The bowl has no pre-drilled faucet holes, so the faucet mounts through the countertop or vanity top. This supports single-hole, three-hole widespread, and wall-mount faucet configurations, with the countertop determining hole placement.
A Bathroom Sink That Works As Hard As the Rest of the Shop
The E-505 brings the same stainless construction found in commercial and industrial environments into the bathroom, pairing a functional, long-wearing material with an undermount installation that keeps the vanity surface clear and clean for the life of the project.
