31-1/2 Inch Undermount Sink For Two-Station Kitchen Workflows
The Karran Profile PU53R is a 16 gauge stainless steel undermount kitchen sink with a large/small bowl layout, sized at 31-1/2 by 20-1/2 by 8-1/2 inches overall. Its unequal bowl configuration gives you a dedicated wash side and a smaller prep or disposal station within a compact footprint, making it a practical fit for kitchens where counter space is at a premium but workflow efficiency still matters.
Key Features
• 16 gauge stainless steel construction delivers a noticeably thicker, heavier bowl than standard 18 gauge sinks in the same category.
• Large/small bowl layout pairs a primary wash basin with a secondary prep or disposal station in a single undermount footprint.
• Undermount installation positions the sink beneath the countertop for a clean, wipe-down counter edge on stone, quartz, or solid surface.
• 8-1/2 inch basin depth accommodates deep pots, sheet pans, and large cookware without overfilling.
• Right-hand small bowl orientation (R suffix) places the smaller basin to the right as installed, matching the most common plumbing and disposal configurations.
Where the Two-Station Layout Earns Its Place
A large/small bowl sink suits kitchens where a single basin forces a constant choice between washing dishes and rinsing produce. The larger bowl handles the main wash load while the smaller side keeps a colander, a running rinse, or a disposal opening within arm's reach. That separation is especially useful in households that hand-wash cookware regularly or in light commercial prep environments where two tasks run simultaneously. The 31-1/2 inch overall length fits a standard 33 inch sink base cabinet, making it a realistic swap in an existing kitchen without cabinet work.
Heavy Gauge Construction and the Profile Series Build
The Profile PU5x line is Karran's 16 gauge tier within the Profile family, a step up from the 18 gauge PU models that share the same body style. Sixteen gauge stainless is thicker, damps sound better under a running faucet, and resists the flex and drumming that thinner bowls develop over years of daily use. The undermount rim is sized and finished for installation beneath stone, quartz, and solid surface countertops, where the rim is concealed and the countertop edge is finished for easy cleaning. Because the sink has no faucet deck, the faucet mounts through the countertop, which keeps the deck clear and lets you choose a wider range of faucet configurations.
Who Reaches For This Sink
Cabinet shops specifying sinks for kitchen projects, kitchen designers sourcing a dependable mid-size undermount for renovation builds, and homeowners replacing an aging basin all find this Profile Series model worth considering. It fits projects where a larger double-bowl would overrun the cabinet but a single bowl would compromise the workflow. The right-hand small bowl orientation (PU53R) suits the majority of kitchen layouts, where the disposal drops to the right and the main wash basin holds center. Installers working with stone or quartz countertops will appreciate a rim and mounting geometry that follows standard undermount practice.
What countertop materials work with this undermount sink?
The PU53R mounts beneath stone, quartz composite, and solid surface countertops using standard undermount clips and silicone, following the countertop fabricator's recommended method. It is not a seamless series sink and does not install with the bevel-bit laminate method.
Is there a left-hand version of this sink available?
The R suffix designates right-hand small bowl orientation. A left-hand variant (PU53L) places the small bowl on the left for layouts where the disposal or secondary plumbing drops to that side. Confirm your plumbing rough-in before ordering.
Does this sink include a grid or strainer?
The PU53R is a bare sink and does not include a bottom grid or basket strainer. Karran's Elite -PK1 packs include grids and strainers, but the Profile Series PU53R ships without them. Matching accessories are available separately and are bowl-specific, so confirm the model when ordering.
What minimum cabinet size does this sink require?
The sink's 31-1/2 inch overall length is designed for a standard 33 inch sink base cabinet. Verify the countertop cutout dimensions against the actual sink before cutting, as published dimensions are nominal.
A Reliable Undermount Built for the Long Run
The Profile PU53R brings 16 gauge construction and a practical two-station bowl layout to a mid-size undermount footprint, giving kitchen projects a sink that holds up to real daily use without demanding an oversized cabinet to do it.
