Select Series Stainless Steel Undermount Sink for Symmetrical Kitchen Workflows
The Karran Select Series SU77 is a 16 gauge stainless steel undermount kitchen sink designed for two-station wash-and-rinse work. Its equal double bowl layout divides the basin evenly, and its tight-radius corners give each bowl a clean, squared profile that suits contemporary cabinetry.
Key Features
• 16 Gauge Stainless Steel Construction: Thicker steel than standard 18 gauge sinks, providing a more rigid, quieter bowl.
• Equal Double Bowl Configuration: Both bowls share the same interior dimensions, so either side handles a full washing load.
• Tight-Radius Corners: Squared bowl corners deliver a modern, architectural interior profile.
• Undermount Installation: Mounts beneath the countertop for a clean, wipe-through counter edge — suitable for granite, quartz, and solid surface countertops.
• Satin Brushed Finish: The brushed surface minimizes the appearance of water spots and light scratches during daily use.
Where the Symmetrical Layout Works Hardest
A 50/50 equal bowl configuration suits any kitchen where both sides of the sink see heavy use. One bowl holds soapy wash water while the other serves as a dedicated rinse station — a workflow that makes sense for homes that hand-wash dishes, busy prep kitchens, or cabinetry showrooms outfitting a working demonstration kitchen. The 9-1/2 inch bowl depth also accommodates deeper pots and hotel pans without the rim getting in the way. Because the two bowls are identical, neither side becomes a bottleneck, and a disposal can mount on whichever side the plumbing layout favors.
Construction Built for a Professional Install
The Select Series is built around 16 gauge Type 304 stainless steel, which is a gauge step heavier than the 18 gauge material common in builder-grade sinks. Heavier gauge reduces flex and dampens vibration, qualities that matter in a high-use kitchen or in any project where the finished product is expected to outlast the surrounding finishes. The undermount design attaches beneath the countertop surface, so the counter edge — whether granite, engineered quartz, or solid surface — remains uninterrupted and wipes clean without a rim channel to trap debris. Tight-radius corners complete the picture, aligning this sink with the squared, contemporary cabinetry styles that cabinet shops and designers currently specify most.
Right Fit for the Job and the Installer
This sink suits cabinet shops specifying complete kitchen packages, designers sourcing for a contemporary kitchen renovation, and contractors installing in stone or solid surface countertops where the undermount method is the right approach. Homeowners who want a sink that holds its look through daily use will appreciate the 16 gauge build and the brushed satin surface. The equal bowl layout is particularly well matched to households that split kitchen duties between two people — a common scenario in open-plan kitchens where two cooks work side by side. This is a dry indoor installation; plan faucet holes through the countertop, since the sink has no integral faucet deck.
Frequently Asked Questions
Does the Select Series SU77 include a drain, grid, or template?
Included components should be confirmed at the time of order. Karran's Select Series sinks do not include a paper template or undermount clips per the series documentation. Check the product listing for current pack contents before purchasing companion hardware separately.
What countertop materials work with this undermount sink?
Undermount installation suits granite, engineered quartz, and solid surface countertops — materials thick and rigid enough to support the sink from below. Laminate tops are not engineered for undermount installations and are not appropriate here.
How do I mount a faucet with this sink?
The SU77 has no integral faucet deck, so the faucet, soap dispenser, and any other accessories mount through holes drilled in the countertop behind the sink. Coordinate hole quantity and spacing with the countertop fabricator before the slab is cut.
Is this sink suitable for a garbage disposal on one side?
Yes. Because the two bowls are equal and independent, a disposal flange can be fitted to either bowl depending on the plumbing layout. Verify the disposal flange size matches the sink's drain opening before ordering.
Why does gauge matter in a stainless steel sink?
Gauge is the thickness of the steel: a lower gauge number means thicker material. At 16 gauge, the Select Series bowl is stiffer and less prone to flexing under load than an 18 gauge sink, and it absorbs vibration better — which reduces the hollow drumming sound common in lighter sinks.
A Sink Built to Stay Out of the Way and Get the Work Done
When the goal is a symmetrical, high-use undermount sink that holds its look and structure through years of daily use, the Select Series SU77 delivers it without requiring compromises on gauge, corner profile, or bowl balance.
