Deep Single Bowl and a Complete Kit, Ready to Install
The Karran Profile Series PU27 is an 18-gauge stainless steel undermount kitchen sink built for kitchens where every inch of counter space matters and a clean, rimless look is the goal. At 23 inches by 17-3/4 inches with an 8-3/4 inch bowl depth, it delivers genuine working capacity in a compact footprint — and it ships as a complete kit with the accessories needed to finish the install.
Key Features
• 18-gauge stainless steel construction provides a solid, sound-dampening bowl for everyday kitchen work.
• Undermount installation puts the rim beneath the countertop, leaving a clean wipe-down edge on the counter surface above.
• 8-3/4 inch bowl depth accommodates tall pots, colanders, and sheet pans without crowding the basin.
• Single bowl configuration gives uninterrupted workspace across the full interior, with no divider in the way of large cookware.
• Ships as a -PK1 kit including a stainless steel basket strainer, bottom grid, and Luster Pro oil so the sink arrives job-ready.
• Brushed satin finish blends with a wide range of hardware and appliance finishes and resists visible surface marks in daily use.
Where This Sink Fits the Job
The PU27 is the right call when a kitchen needs a capable undermount sink but the cabinet run is sized for something narrower than a standard 30-inch or 33-inch basin. Secondary kitchen stations, apartment renovations, tight galley layouts, and butler's pantry installs are natural fits. The 23-inch exterior width works in base cabinets sized for it, so confirm the minimum cabinet opening before cutting. Because it undermounts, the countertop material matters: stone, quartz, and solid surface all support undermount attachment well, while laminate installations require a different approach. The faucet mounts through the countertop above, since this sink has no faucet deck of its own.
Construction and the Kit Contents
Profile Series construction uses an 18-gauge stainless bowl with a brushed satin finish that softens fingerprints and wipes clean without special care. The gauge sits in the mid-range of the stainless market — heavier than economy sinks and suited to residential and light-duty professional use. The -PK1 pack resolves a common frustration with sink purchases: the basket strainer, bottom grid, and Luster Pro protective oil are in the box. The grid lifts the bowl floor away from standing water, protecting both the sink surface and whatever's resting in it. Luster Pro is applied after installation to condition and protect the stainless finish. The drain assembly is not included and is sold separately; order it alongside the sink to avoid a return trip.
Who Orders This Sink
Cabinet shops fitting out a compact kitchen, contractors working through a multi-unit renovation, and homeowners planning a kitchen refresh all reach for this sink when the priority is a reliable undermount in a smaller size class. The kit format appeals to anyone who has been caught short by a sink that arrived without a strainer or grid. Designers specifying secondary prep stations and island sinks find the compact footprint and the kit format simplify the spec. For volume projects, having strainers and grids arrive with each sink removes a common punch-list item.
Does this sink work with laminate countertops?
Standard undermount installation is intended for stone, quartz, and solid surface countertops that can support the bowl from below. Laminate installations require a seamless-series sink like Karran's Q Series or Edge Series, which use different fabrication methods designed for laminate. This Profile Series sink is not a seamless product.
Is the drain included in the kit?
No. The -PK1 kit includes the basket strainer, bottom grid, and Luster Pro oil, but the drain assembly is sold separately. Add a 3-1/2 inch kitchen drain to your order to have everything on hand for install day.
Where does the faucet mount on this sink?
This sink has no faucet deck, so the faucet mounts through the countertop behind the bowl. Plan your countertop drilling for the faucet and any accessories like a soap dispenser before the countertop is fabricated.
What is the minimum cabinet size needed?
Karran's spec sheet for the PU27 states the minimum cabinet size required. Confirm that value against the sink's spec sheet before cutting — the overall sink dimension and the cabinet opening are distinct measurements.
What does Luster Pro oil do, and when is it applied?
Luster Pro is Karran's conditioning oil for stainless surfaces. It is applied after installation to protect and enhance the brushed finish. The product is included in the -PK1 kit.
A Sink Kit That Keeps the Project Moving
The PU27-PK1 pairs a compact, workhorse stainless bowl with the accessories to finish the job without a second order — making it a practical choice for contractors, cabinet shops, and homeowners who want the install done right the first time.
