Stainless Steel Precision and a 36-Inch Cabinet Fit

This Karran undermount kitchen sink is a 31-1/2-inch equal double-bowl sink in 18-gauge stainless steel, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch base cabinet.

Key Features

• 18-gauge stainless steel construction gives the sink a solid, dent-resistant body suited to daily kitchen use.
• Equal 50/50 double bowl splits washing and rinsing into two independent basins.
• Undermount installation for granite, quartz, and solid surface countertops.
• 8-3/4-inch inside bowl depth accommodates large pots and baking sheets.
• IAPMO certified to meet plumbing code requirements.
• Requires a minimum 36-inch base cabinet for proper fit and clearance.

Two Bowls, One Workspace

Equal double-bowl sinks divide kitchen sink work into two dedicated stations. One side handles soaking or washing; the other stays open for rinsing produce, prepping ingredients, or draining pasta. The two-basin layout is especially useful in kitchens where multiple people work at the same time, or where keeping clean dishes separate from a soapy basin matters during a big cook. At 8-3/4 inches deep, both bowls have room for stock pots and roasting pans without forcing an awkward tilt.

18-Gauge Stainless Steel, Undermount Ready

The sink is built from 18-gauge stainless steel, a thickness that balances rigidity with reasonable weight and resists the flexing and drumming that thinner-gauge bowls can develop over time. It mounts beneath the countertop so the counter surface runs flush to the bowl edge, eliminating the rim ledge where water and crumbs collect around a drop-in. This undermount approach requires a countertop material that supports the method: granite, quartz, or solid surface. IAPMO certification confirms the sink meets the plumbing code requirements that inspectors and general contractors typically look for on residential projects.

Cabinet Size and Project Fit

At 31-1/2 inches side to side, this sink fits a 36-inch base cabinet with standard clearance on each side. It suits a primary kitchen sink run in a remodel or new build where the countertop is being fabricated to accept an undermount. Because it mounts under the counter, it needs to be specified into the countertop plan before the stone or surface material is cut. Designers and cabinet shops specifying a full kitchen package will find it straightforward to coordinate with a 36-inch base; contractors sourcing for an install should confirm the countertop material is one of the three compatible types before the countertop order is placed.
