The Karran Profile PU55 is a 16-gauge stainless steel undermount kitchen sink with a single deep bowl, designed to install beneath granite, quartz, or solid surface countertops and sized to fit a 33-inch minimum cabinet width.
A single uninterrupted basin makes this sink the practical choice when the job calls for fitting large sheet pans, stockpots, or full-sized cutting boards into the sink without a divider getting in the way. The 9-inch interior depth keeps water and mess contained during heavy prep and cleanup. Without a center divide, washing oversized items is straightforward, and the clean sightline across the basin reads well in an open kitchen layout.
At 16 gauge, the stainless steel is meaningfully thicker than the 18-gauge material used in most entry-level sinks. A thicker bowl resists flexing under load, deadens sound better, and tends to hold its shape through years of use. The stainless finish here is the mill-standard look that coordinates with stainless appliances and hardware without requiring an exact match. Because this is an undermount design, the countertop edge is the finished surface seen from above, and the bowl drops cleanly below it. That mounting method requires a hard countertop material, specifically granite, quartz, or solid surface, so the countertop adhesive and substrate can support the weight of the bowl from underneath.
This is a sink for a primary kitchen workspace where a single large basin is preferred over split bowls, and where the countertop is granite, quartz, or solid surface. It suits a new build or a full kitchen remodel where the countertop is being fabricated around the sink cutout. Designers specifying a clean, frameless countertop edge will find the undermount format does exactly what it should. Cabinet shops and contractors fitting 33-inch or wider base cabinets can plan the 30-1/4-inch sink length into the layout with a straightforward cutout. The cUPC certification means it meets the plumbing code requirements for residential and commercial installations in the US and Canada.
This sink is designed to undermount into granite, quartz, and solid surface countertops. These hard materials provide the substrate strength needed to support an undermount bowl. It is not intended for laminate countertops.
Undermount sinks are best planned into a new or replacement countertop where the cutout is fabricated for the bowl. Installing into an existing cutout sized for a different sink is not recommended because the cutout dimensions and mounting ledge need to match this bowl's footprint.
The sink requires a 33-inch minimum cabinet width. The overall sink length is 30-1/4 inches side to side and 18 inches front to back.
No. This sink is not ADA compliant. For ADA-required installations, confirm the required specifications before selecting a sink.
The Karran Profile PU55 delivers a deep, rigid 16-gauge stainless basin that mounts cleanly beneath a hard countertop and handles the demands of a busy kitchen sink station.
