16 Gauge Stainless Steel Undermount Sink Built for a Two-Station Kitchen Workflow
The Karran Profile PU53L-PK1 is a 16 gauge stainless steel undermount kitchen sink with a small/large bowl configuration, sized at 31-1/2 by 20-1/2 by 8-1/2 inches and sold as a complete kit with installation essentials included. It is designed for kitchens where one bowl handles the heavy washing and the other holds prep, rinsing, or a disposal setup.
Key Features
• 16 gauge stainless steel construction delivers noticeably heavier walls than standard 18 gauge sinks, reducing flex and noise under daily use.
• Small/large bowl layout separates the primary wash area from a secondary prep or rinse station within a compact 31-1/2 inch footprint.
• 8-1/2 inch bowl depth provides enough clearance for large pots, sheet pans, and deep cookware without straining over a shallow basin.
• Undermount installation keeps the countertop edge unobstructed, making cleanup fast and the finished look clean.
• Kit includes basket strainers, bottom grids, and Luster Pro oil, so the sink arrives ready for installation without a separate accessory order.
Where the Two-Bowl Layout Earns Its Place
A small/large bowl sink fits kitchens where a single basin creates a bottleneck. The large bowl takes on soaking and washing, while the smaller bowl handles a colander, a cutting board rinse, or a disposal connection alongside it. For households that cook seriously or kitchens that see high traffic, the divided layout keeps both stations functional at the same time rather than forcing one task to wait on another. Cabinet shops and contractors specifying sinks for kitchen renovations will find the 31-1/2 inch overall width fits standard 33 inch sink base cabinets with room to spare on the countertop.
Construction and Kit Contents
The Profile Series PU53L is built from 16 gauge Type 304 stainless steel, the same thickness used in the Elite line, giving the bowl a solid, dampened feel that thinner-gauge sinks cannot match. The brushed satin finish resists water spotting and surface marks in everyday kitchen conditions. Because this SKU ships as a -PK1 kit, it includes stainless steel basket strainers sized for each drain opening, bottom grids to protect the bowl floors, and a bottle of Karran Luster Pro oil for the initial finish care. The faucet mounts through the countertop behind the sink rather than through a deck on the sink itself, giving the fabricator or installer control over hole placement and faucet selection.
The Right Fit for This Sink
This sink suits homeowners replacing an existing undermount in a 33 inch or wider sink base, designers specifying a workhorse stainless sink for a cabinet package, and cabinet shops building kitchens where the client wants a divided bowl without moving to a 36 inch base. The 8-1/2 inch depth and 16 gauge build also make it a practical specification for rental units and contractor-grade kitchens where longevity and easy cleaning matter more than a specialty finish. Because this is an undermount model, the countertop material should support undermount installation — quartz, granite, and solid surface are the typical choices.
Is the left-bowl or right-bowl orientation specified in the model number?
The L suffix in PU53L designates the bowl orientation. Confirm the layout against your cabinet run before ordering — a companion model covers the opposite orientation if needed.
Do the included grids fit both bowls, or just one?
The -PK1 kit includes bottom grids matched to the PU53L's bowls. Grids in this catalog are model- and bowl-specific, so the grids in this kit are made for these bowls and not interchangeable across other Profile models.
Does the kit include a drain or a template?
The kit includes basket strainers (which seat in the drain openings), bottom grids, and Luster Pro oil. A paper template and undermount clips are not included; the countertop fabricator typically supplies the cutout template and the mounting hardware suited to the countertop material.
What countertop materials work with this undermount sink?
As a conventional undermount, the PU53L installs in quartz, granite, and solid surface countertops using each material's standard undermount clip and adhesive method. It is not a seamless-series sink and does not use Karran's laminate fabrication method.
A Sink Kit That Arrives Ready to Install
Ordering a sink and sourcing the accessories separately adds steps and the risk of a mismatch. The PU53L-PK1 bundles the grids, strainers, and care oil with the sink so the installation can move forward the day it arrives — no back-order on a basket strainer holding up a countertop drop.
