The BSC PREFERRED LR2521PD4 is a single bowl drop-in kitchen sink constructed from 18-gauge Type 304 stainless steel with a scratch-resistant Lustertone finish. It measures 25 inches in length, 21.25 inches in width, and 7.875 inches in depth. The sink incorporates a Perfect Drain design that eliminates gaps around the drain opening, channeling food and debris directly into the drain for easier cleanup. Straight sidewalls and a flat bottom maximize usable bowl space. Bottom sound-deadening pads reduce noise and vibration during use. Licensed plumbers and experienced tradespeople handle installation in residential kitchen applications.
This sink fits countertop cutouts measuring 24.375 inches by 20.625 inches and requires a minimum base cabinet width of 30 inches. The interior bowl dimensions are 21 inches in length and 15.75 inches in width, providing substantial capacity for cookware and large items. The four-hole faucet configuration supports a wide range of faucet and accessory layouts. Drop-in mounting is accomplished using U-channel clips that secure the sink to the countertop deck from below. The 1.5-inch corner radius gives the bowl a clean, defined profile consistent with modern kitchen cabinetry.
Designed for drop-in installation in residential kitchen countertops requiring a cutout of 24.375 inches by 20.625 inches with a minimum base cabinet width of 30 inches. Compatible with four-hole faucet configurations.
Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and disconnect existing drain and supply lines before removing any existing sink. Apply a continuous bead of plumber's putty or silicone sealant around the cutout perimeter before setting the sink, then secure with U-channel mounting clips tightened evenly from below. Confirm drain alignment and connection integrity before restoring water supply and testing for leaks.
